In building materials, zinc isoctanoate mainly reacts chemically with active groups on the surface of the substrate to form a dense protective film, thereby effectively preventing moisture penetration. At the same time, zinc isoctanoate can also enhance the adhesion and weather resistance of the material and extend the service life of the building. Therefore, studying the application of zinc isoctanoate in building materials will not only help improve the waterproof performance of buildings, but also promote the process of green buildings and sustainable development.

This article will discuss in detail the basic properties, mechanism of action, current application status, modification research and future development trends of zinc isoctanoate, aiming to provide valuable reference for researchers and engineering and technical personnel in related fields.

The basic properties of zinc isoctanoate

Zinc 2-Ethylhexanoate is a common organic zinc compound with a chemical formula of Zn(C8H15O2)2 and a molecular weight of 376.7 g/mol. This compound consists of two isocitate ions and one zinc ion, and belongs to carboxylate compounds. Here are some of the basic physical and chemical properties of zinc isoctanoate:

1. Physical properties

• Appearance: Zinc isoctanoate is usually a white or slightly yellow crystalline powder with good fluidity.
• Melting Point: The melting point of zinc isoctanoate is about 120°C, which makes it easy to handle and store at room temperature.
• Solution: Zinc isoctanoate has good solubility in organic solvents, especially in polar solvents such as alcohols, ketones, and esters. However, it's in the waterThe solubility in the medium is low, at only 0.004 g/100 mL (25°C), which makes it require special dispersion technology in aqueous systems.
• Density: The density of zinc isoctanoate is about 1.1 g/cm³, which makes it have good settlement stability in the mixture.
• Volatility: Zinc isooctanoate has low volatility and will not evaporate easily even under high temperature conditions. Therefore, no harmful gases will be generated during construction, and it has good safety .

2. Chemical Properties

• Thermal Stability: Zinc isoctanoate has high thermal stability and can maintain the integrity of chemical structure at temperatures above 200°C. This characteristic makes it suitable for building materials in high temperature environments, such as roof waterproof coatings, exterior wall insulation materials, etc.
• Antioxidation: Zinc isoctanoate has strong antioxidant ability, can effectively inhibit the free radical reaction in the material and delay the aging process of the material. Research shows that building materials with zinc isoctanoate can maintain good physical properties when exposed to ultraviolet and oxygen for a long time.
• Reactive activity: Zinc isoctanoate can react chemically with a variety of functional groups, especially with substances containing active groups such as hydroxyl groups, carboxyl groups, amino groups, etc. to form stable complexes. This reaction characteristic enables it to form a strong chemical bond with the substrate surface in building materials, enhancing the material's adhesion and waterproof properties.
• pH sensitivity: Zinc isooctanoate is more sensitive to pH. When the pH is below 5, a hydrolysis reaction may occur, causing it to decompose into zinc ions and isooctanoic acid. Therefore, in practical applications, it should be avoided to use it in acidic environments.

3. Safety and environmental protection

• Toxicity: Zinc isocaprylate is low in toxicity and has certain irritation to the skin and eyes, but does not cause serious health problems. According to the International Chemical Safety Card (ICSC), the acute oral toxicity LD50 value of zinc isoctanoate is 2000 mg/kg (rat), which is a low-toxic substance.
• Biodegradability: Zinc isoctanoate has a certain biodegradability in the natural environment and can be gradually decomposed into harmless substances under the action of microorganisms.

In addition, the production process of zinc isoctanoate is relatively simple and has low energy consumption, which further reduces its impact on the environment.

4. Preparation method

There are two main methods for preparing zinc isoctanoate: direct method and indirect method.

• Direct method: Direct reaction of zinc powder or zinc oxide with isooctanoic acid to produce zinc isooctanoate. This method is simple to operate, mild reaction conditions, and is suitable for large-scale industrial production. The reaction equation is as follows:
  [ Zn + 2C8H15COOH → Zn(C8H15COO)2 + H2 ]

• Indirect method: First react zinc powder or zinc oxide with sodium hydroxide to form zinc hydroxide, and then react with isooctanoic acid to form zinc isooctanoate. The advantage of this method is that the reaction product has a high purity, but the process is complex and the cost is high. The reaction equation is as follows:
  [ Zn(OH)2 + 2C8H15COOH → Zn(C8H15COO)2 + 2H2O ]

To sum up, zinc isoctanoate has excellent physical and chemical properties, especially in terms of thermal stability, antioxidant and reactive activity. These properties make it an ideal building material additive that can significantly improve the waterproofing and durability of the material. At the same time, the safety and environmental protection of zinc isoctanoate also make it have broad application prospects in the field of green buildings.

The mechanism of action of zinc isoctanoate in building materials

The application of zinc isoctanoate in building materials is mainly based on its unique chemical structure and reaction characteristics. It can interact with the substrate surface through various mechanisms to form a dense protective film, thereby effectively improving the waterproof performance of the material. Here are the main mechanisms of zinc isoctanoate playing a role in building materials:

1. Surface chemical reaction

The zinc ions in zinc isoctanoate have strong coordination ability and can coordinate with active groups (such as hydroxyl, carboxyl, amino, etc.) on the surface of the substrate to form a stable complex. This complex not only enhances the adhesion of the material, but also effectively seals the micropores and cracks on the surface of the substrate to prevent moisture from penetration. Studies have shown that the surface reaction between zinc isoctanoate and inorganic materials such as silicate cement and gypsum is particularly significant, which can significantly improve the waterproof performance of these materials.

For example, when zinc isoctanoate reacts with Ca(OH)₂ in silicate cement, a dense calcium-zinc composite film is formed, which has good hydrophobicity and corrosion resistance. The reaction equation is as follows:
[ Ca(OH)₂ + Zn(C8H15COO)2 → CaZn(C8H15COO)4 + 2H2O ]

In addition, zinc isoctanoate can also cross-link with active groups in organic polymers to form a three-dimensional network structure, further enhancing the mechanical properties and waterproof properties of the material. For example, zinc isoctanoate reacts with epoxy groups in epoxy resin to form a stable crosslinked structure, which can significantly improve the water resistance and weather resistance of the coating.

2. Interface modification

Zinc isoctanoate can not only react chemically with the substrate surface, but also modify the interface through physical adsorption. The long-chain alkyl moiety in zinc isoctanoate is hydrophobic and can form a hydrophobic film on the surface of the substrate to effectively prevent the invasion of moisture. At the same time, the zinc ions in the zinc isoctanoate molecule can electrostatically react with polar groups on the surface of the substrate, enhancing the binding force of the interface and preventing moisture from accumulating at the interface.

Study shows that zinc isoctanoate has a particularly obvious interface modification effect on porous materials such as concrete and masonry. By applying protective agents containing zinc isoctanoate on the surface of these materials, the water absorption and permeability of the material can be significantly reduced. The experimental results show that the water absorption rate of concrete samples treated with zinc isoctanoate was reduced by about 50% and the permeability coefficient was reduced by about 70%.

3. Hydrophobic effect

Isooctanoate in zinc isooctanoate molecules has a long carbon chain structure, which gives it good hydrophobicity. When zinc isoctanoate reacts with the surface of the substrate, a hydrophobic layer will be formed on the surface of the material, effectively preventing the penetration of moisture. Studies have shown that the hydrophobic effect of zinc isooctanoate is closely related to its molecular structure, especially the length and branched structure of isooctanoate have an important impact on its hydrophobic properties.

To verify the hydrophobic effect of zinc isoctanoate, the researchers conducted a contact angle test. The results show that the water contact angle of the untreated concrete surface is about 50°, while the water contact angle of the concrete surface after zinc isoctanoate treatment reaches above 110°, showing obvious superhydrophobic characteristics. This shows that zinc isoctanoate can significantly improve the surface hydrophobicity of the material, thereby enhancing its waterproofing properties.

4. Antibacterial and mildew

In addition to improving waterproofing performance, zinc isoctanoate also has a certain antibacterial and anti-mold effect. Zinc ions have broad-spectrum antibacterial activity and can inhibit the growth and reproduction of a variety of bacteria, fungi and molds. Studies have shown that zinc isocitate has a strong inhibitory effect on common pathogenic microorganisms such as E. coli, Staphylococcus aureus, and Aspergillus niger, and can effectively prevent building materials from becoming moldy and deteriorating in humid environments.

The antibacterial and anti-mold mechanism of zinc isocitate is mainly related to the release of its zinc ions. Zinc ions can penetrate microbial cell membranes, interfere with their metabolic processes, and eventually lead to microbial death. In addition, zinc isoctanoate can react with proteins on the surface of microorganisms, destroy its cellular structure, and further enhance the antibacterial effect.

5. Weather resistance enhancement

Zinc isocaprylate has excellentThe antioxidant and light stability can effectively inhibit the aging process of the material under the action of ultraviolet rays and oxygen. Research shows that zinc isoctanoate can capture free radicals and prevent the chain reaction it triggers, thereby delaying the aging rate of material. In addition, zinc isoctanoate can also work synergistically with ultraviolet absorbers to further improve the weather resistance of the material.

To verify the weather-enhanced effect of zinc isoctanoate, the researchers conducted accelerated aging tests. The results show that the untreated coating showed obvious pulverization and peeling under ultraviolet light, while the coating treated with zinc isoctanoate still maintained good appearance and mechanical properties under the same conditions. This shows that zinc isoctanoate can significantly improve the weather resistance of the coating and extend its service life.

Application Status

Zinc isooctanoate, as an efficient building material additive, has been widely used in many fields. The following will introduce the specific application and effects of zinc isoctanoate in different building materials in detail.

Modification Research

Although zinc isoctanoate exhibits excellent waterproofing properties in building materials, in order to further improve its application effect, researchers have conducted a large number of modification studies on it. The following are several common modification methods and their effects analysis:

1. Nanomorphic Modification

Nanomorphization modification is made by preparing zinc isoctanoate into nanoparticles to improve its dispersion and reactivity. Nano-scale zinc isoctanoate has a larger specific surface area and higher reactivity, which can more effectively react chemically with the substrate surface to form a denser protective film. Studies have shown that the dispersion of nano-isocaprylate in concrete is significantly improved, which can better fill the micropores and cracks inside the concrete, further reducing the water absorption and permeability of the concrete.

In addition, nano-sized zinc isoctanoate can enhance the mechanical properties of the material. The experimental results show that the concrete samples treated with nano-isocaprylate have significantly improved in terms of compressive strength and flexural strength. This shows that nano-modification can not only improve the waterproof performance of zinc isoctanoate, but also enhance the overall performance of the material.

2. Compound Modification

Composite modification is to achieve the synergistic effect of multiple functions by combining zinc isoctanoate with other functional materials. Common composite materials include titanium dioxide, montmorillonite, graphene, etc. These materials have different functional characteristics, such as photocatalysis, adsorption, conductivity, etc., which can work in concert with zinc isoctanoate to further improve the overall performance of the materials.

For example, after zinc isoctanoate is combined with titanium dioxide, strong oxidative free radicals can be generated under light conditions, further enhancing the antibacterial and anti-mold properties of the material. Research shows that zinc isoctanoate-titanium dioxideComposite materials have a stronger inhibitory effect on common pathogenic microorganisms such as E. coli and Staphylococcus aureus, and can effectively prevent the material from becoming moldy and deteriorating in humid environments.

For example, after zinc isoctanoate is combined with montmorillonite, a protective film with self-healing function can be formed on the surface of the material. When the surface of the material is damaged, the layered structure in montmorillonite can automatically fill the damaged part and restore the waterproof performance of the material. The experimental results show that the concrete samples treated with zinc isoctanoate-montmorillonite composite still maintain a low water absorption rate and permeability coefficient after multiple scratch tests.

3. Graft modification

Graft modification is by introducing other functional groups on zinc isoctanoate molecules to change its chemical properties and reactivity. Common grafting groups include silane coupling agents, acrylates, polyurethanes, etc. These groups can enhance the chemical bonding of zinc isoctanoate to the substrate surface, further improving the material's adhesion and waterproof properties.

For example, after zinc isoctanoate is grafted with a silane coupling agent, a protective film with excellent adhesion can be formed on the concrete surface. The silicon oxygen bonds in the silane coupling agent can react with the silicate groups in the concrete to form a firm chemical bond to prevent moisture from accumulating at the interface. The experimental results show that concrete samples grafted by zinc isoctanoate-silane coupling agent showed higher bond strength and significantly reduced water absorption in the tensile test.

For example, after zinc isoctanoate is grafted with acrylate, a polymer network with self-crosslinking function can be formed in the coating. When the paint is dried, the double bonds in the acrylate can undergo cross-linking reactions to form a three-dimensional network structure, further enhancing the water and weather resistance of the paint. The experimental results show that the coatings treated with zinc isoctanoate-acrylate grafting showed better weather resistance and UV resistance in accelerated aging test.

4. Bio-based modification

Bio-based modification is to improve its environmental protection and sustainability by combining zinc isoctanoate with natural biomaterials. Common bio-based materials include chitosan, cellulose, lignin, etc. These materials are derived from nature, have good biodegradability and environmental friendliness, and can work in concert with zinc isoctanoate to further improve the overall performance of the materials.

For example, after zinc isoctanoate is combined with chitosan, a protective film with antibacterial and anti-mold function can be formed on the surface of the material. The amino group in chitosan can coordinate with zinc ions in zinc isoctanoate to form a stable complex and enhance the antibacterial properties of the material. Studies have shown that zinc isoctanoate-chitosan composites have a stronger inhibitory effect on common pathogenic microorganisms such as E. coli and Staphylococcus aureus, and can effectively prevent the material from becoming moldy and deteriorating in humid environments.

For example, after zinc isoctanoate is combined with cellulose, a protective film with excellent flexibility can be formed on the surface of the material. The hydroxyl groups in cellulose can react with zinc ions in zinc isoctanoate to form stable chemical bonds, which enhancesThe flexibility and impact resistance of the material. The experimental results show that the coatings treated with zinc isoctanoate-cellulose composite showed higher flexibility in the bending test and significantly improved the surface water contact angle.

Future development trends

Zinc isoctanoate, as an efficient building material additive, has shown great potential in improving waterproofing performance. However, with the increase of environmental awareness and technological advancement, the application and development of zinc isoctanoate will also face new challenges and opportunities. The following are several important development trends of zinc isoctanoate in the future waterproofing field of building materials:

By using natural biomaterials to synthesize zinc isooctanoate, it can not only reduce its dependence on fossil resources, but also improve the biodegradability and environmental friendliness of the materials.

Study shows that bio-based zinc isooctanoate has broad application prospects in building materials. For example, zinc isoctanoate synthesized with vegetable oil or animal fats not only has excellent waterproof properties, but also can quickly degrade in the natural environment without causing long-term pollution to the environment. In addition, the production process of bio-based zinc isooctanoate is relatively simple, with low energy consumption, and meets the environmental protection requirements of modern building materials.

2. Intelligent and multifunctional

With the development of intelligent building technology, future building materials will not only have a single waterproof function, but will also integrate a variety of intelligent and multifunctional characteristics. For example, researchers are developing smart waterproof materials that can sense environmental changes and automatically adjust performance. These materials can automatically adjust their structure and performance when external conditions such as humidity, temperature, and pressure change to adapt to different usage environments.

Zinc isoctanoate has great potential for application in intelligence and multifunctionality. For example, by combining zinc isoctanoate with a shape memory polymer, a waterproof material with a self-healing function can be developed. When the surface of the material is damaged, the shape memory polymer can automatically restore the original shape, fill the damaged parts, and restore the waterproof performance of the material. In addition, zinc isoctanoate can also be combined with other functional materials to develop composite materials with antibacterial, fireproof, heat insulation and other functions to meet the needs of different application scenarios.

Nanoized zinc isoctoate has moreLarge specific surface area and higher reactivity can more effectively react chemically with the surface of the substrate to form a denser protective film. In addition, nano-sized zinc isoctanoate can also enhance the mechanical properties of the material and extend its service life.

Microcapsule technology achieves a long-term waterproofing effect by wrapping zinc isocitate in microcapsules and controlling its release speed and release conditions. Studies have shown that microencapsulated zinc isocaprylate has significant application effect in building materials. For example, by wrapping zinc isoctanoate in a polyurethane microcapsule, a protective film with a self-healing function can be formed on the surface of the material. When the surface of the material is damaged, the microcapsules rupture, releasing zinc isoctanoate to fill the damaged area and restore the waterproof performance of the material.

4. Standardization and standardization

With the widespread application of zinc isoctanoate in building materials, it is particularly important to formulate unified standards and specifications. Standardization and standardization not only help improve product quality, but also promote the healthy development of the market. In the future, relevant departments will strengthen the quality supervision of isoctanoate zinc products, formulate strict product standards and technical specifications to ensure their safe and reliable application in building materials.

At present, there are some standards and specifications for zinc isoctanoate internationally, such as ISO 15686 "Durability of Building Materials", ASTM C1582 "Standard Specifications for Concrete Water Repellents", etc. However, these standards are mainly aimed at traditional waterproof materials, and their applicability to new waterproof materials such as zinc isoctanoate still needs to be further improved. Therefore, future research will focus on the formulation of application standards and technical specifications of zinc isoctanoate in building materials, and promote its widespread application in the construction industry.
