1. Introduction

With the increasing global environmental awareness, environmentally friendly materials are being used in various fields more and more widely. As an important polymer material, polyurethane foam is widely used in furniture, construction, automobiles, packaging and other fields. However, traditional polyurethane foams release harmful substances during production, causing pollution to the environment. Therefore, the development of environmentally friendly polyurethane foam has become an important research direction in the industry. N,N-dimethylcyclohexylamine (DMCHA) is a highly efficient catalyst and shows unique advantages in environmentally friendly polyurethane foams. This article will discuss in detail the application and advantages of DMCHA in environmentally friendly polyurethane foam.

2.3 Chemical Properties

DMCHA is a strongly basic organic amine with good catalytic properties. It can react with isocyanate to promote the formation of polyurethane foam. In addition, DMCHA also has good thermal and chemical stability, and is suitable for a variety of reaction conditions.

3. Overview of environmentally friendly polyurethane foam

3.1 Basic concepts of polyurethane foam

Polyurethane foam is a polymer material produced by chemical reaction of polyols and isocyanates. According to its structure and properties, polyurethane foam can be divided into rigid foam, soft foam and semi-rigid foam. Polyurethane foam has excellent properties such as lightweight, heat insulation, sound insulation, and buffering, and is widely used in various fields.

3.2 Definition of environmentally friendly polyurethane foam

Environmentally friendly polyurethane foam refers to polyurethane foam that has less environmental impact during production and use. Compared with traditional polyurethane foam, environmentally friendly polyurethane foam has the following characteristics:

• Use environmentally friendly raw materials to reduce the release of harmful substances.
• Reduce energy consumption and waste emissions during production.
• The product has good durability and recyclability during use.

3.3 Application fields of environmentally friendly polyurethane foam

Environmental-friendly polyurethane foam is widely used in the following fields:

• Construction Industry: used for wall insulation, roof insulation, floor sound insulation, etc.
• Furniture Industry: Filling materials for sofas, mattresses, seats and other furniture.
• Auto industry: used in car seats, instrument panels, door linings, etc.
• Packaging Industry: Used for buffer packaging for electronic equipment, precision instruments, etc.

4. Application of DMCHA in environmentally friendly polyurethane foam

4.1 The mechanism of action of DMCHA as a catalyst

DMCHA mainly plays a catalyst in the synthesis of polyurethane foam. Its mechanism of action is as follows:

1. Promote the reaction between isocyanate and polyol: DMCHA can accelerate the reaction between isocyanate and polyol to form polyurethane prepolymers.
2. Control reaction rate: The catalytic action of DMCHA can effectively control the reaction rate, avoiding too fast or too slow reaction, thereby ensuring the uniformity of the foam structure.
3. Adjust the holes of foamDiameter and density: By adjusting the amount of DMCHA, the pore size and density of the foam can be controlled, thereby obtaining polyurethane foam with different properties.
