Hydrogen-containing silicone oil has a wide range of applications. Dongyue Silicon Materials is a representative enterprise in my country.
Hydrogen-containing silicone oil, also known as polymethylhydrogensiloxane, can form a waterproof film on the surface of various substrates through cross-linking under the action of metal catalysts. Hydrogen-containing silicone oil appears as a colorless and transparent oily liquid with no special odor. It is soluble in carbon tetrachloride, methyl ethyl ketone, dimethyl ether and kerosene, but insoluble in isopropyl alcohol. Hydrogen-containing silicone oil has the characteristics of good hydrophobicity, low volatility, and good weather resistance. It is widely used in synthetic rubber, textile, glass fiber, papermaking and other fields.
The preparation methods of hydrogenated silicone oil include silicone catalytic equilibrium method and co-hydrolysis condensation method. The siloxane catalytic equilibrium method uses hexamethyldisiloxane and methylhydrogendichlorosilane as raw materials, adds concentrated sulfuric acid for full reaction, and then goes through cleaning, distillation, filtration and other processes to obtain the finished product; the co-hydrolysis and condensation method is Trimethylchlorosilane and methylhydrogendichlorosilane are used as raw materials. After hydrolysis, concentrated sulfuric acid is added, and then the finished product is obtained through processes such as cleaning, filtration, and decolorization. This method is a traditional preparation method for hydrogenated silicone oil.
According to different hydrogen contents, hydrogen-containing silicone oil can be divided into two categories: low hydrogen-containing silicone oil and high hydrogen-containing silicone oil. Low hydrogen-containing silicone oil contains low reactive groups and can be used to prepare chemical products such as alkyl modified silicone oil and modified silicone oil. High-hydrogen silicone oil is a representative product of hydrogen-containing silicone oil and is a fully hydrogen-functional silicone oil that can participate in a variety of chemical reactions. , has a wide range of applications.
Hydrogen-containing silicone oil is widely used in synthetic rubber, textile, glass fiber, paper and other fields. In the field of synthetic rubber, hydrogen-containing silicone oil can be used as rubber curing agent and cross-linking agent, and addition liquid silicone rubber, high-temperature vulcanization silicone rubber, high-temperature mixing silicone rubber, etc. are its end products; in the textile field, hydrogen-containing silicone oil can be used As a fabric waterproofing agent, it can improve the friction resistance, breathability and stain resistance of fabrics. As the development of downstream industries accelerates, the market size of hydrogenated silicone oil continues to expand. According to the “2023-2028 China Hydrogen Silicone Oil Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, The global hydrogenated silicone oil market will reach US$410 million in 2022, a year-on-year growth of 7.5%.
Henan Hengxing Technology Co., Ltd., Ningbo Runhe High-tech Materials Technology Co., Ltd., and Shandong Dongyue Silicone Materials Co., Ltd. are the main manufacturers of hydrogenated silicone oil in my country. Dongyue Silicone focuses on the R&D, production and sales of hydrogenated silicone oil and methyl silicone oil. It has participated in the drafting of industry standards such as “Methyl Low Hydrogen Silicone Oil” and “Terminal Hydrogen-containing Dimethyl Silicone Oil” and is the leading supplier of hydrogen-containing silicone oil in my country. Represent the enterprise.
Industry analysts said that hydrogen-containing silicone oil has excellent performance and is widely used in many fields. With the gradual release of downstream demand, the development prospects of the industry will be Keep improving. my country’s hydrogenated silicone oil industry is highly concentrated. As a leading company, Dongyue Silicon Materials continues to increase research on efficient preparation methods for hydrogenated silicone oil. In the future, as local companies continue to exert their efforts, the development speed of my country’s hydrogenated silicone oil industry will further accelerate.
