1. Introduction

Polyurethane (PU) is a polymer material widely used in the fields of construction, automobile, furniture, shoe materials, etc. Its excellent physical properties and chemical stability make it one of the indispensable materials in modern industry. However, the choice of catalyst is crucial in the production process of polyurethane. The catalyst not only affects the reaction rate, but also directly affects the performance of the final product. This article will introduce in detail a catalyst suitable for large-scale polyurethane production-retard amine catalyst A400.

2. Overview of polyurethane production

The production of polyurethane mainly involves two basic reactions: the addition reaction of isocyanate and polyol (i.e. polymerization reaction) and the reaction of isocyanate and water (i.e. foaming reaction). Both reactions require catalysts to accelerate the reaction rate and control the reaction process, thereby obtaining the ideal polyurethane product.

2.1 Polymerization

Polymerization is the core reaction in polyurethane production, and isocyanate reacts with polyols to form polyurethane chains. This reaction requires a catalyst to accelerate the reaction rate and ensure that the reaction is completed within a controlled time.

2.2 Foaming reaction

Foaming reaction is a key step in the production of polyurethane foam. The isocyanate reacts with water to form carbon dioxide gas, forming a foam structure. This reaction also requires a catalyst to control the foaming rate and foam density.

3. Introduction to Retarded Amine Catalyst A400

The delayed amine catalyst A400 is a highly efficient catalyst designed specifically for large-scale polyurethane production. It has a delayed catalytic effect and can maintain a low catalytic activity at the beginning of the reaction, gradually releasing catalytic activity as the reaction progresses, thereby achieving precise control of the reaction process.

3.1 Delayed catalytic mechanism

The delayed catalytic mechanism of the delayed amine catalyst A400 mainly depends on the special functional groups in its molecular structure. These functional groups form stable intermediates with isocyanate or polyol at the beginning of the reaction, temporarily inhibiting catalytic activity. As the reaction progressesThe intermediate gradually decomposes, releasing active catalysts, thereby achieving precise control of the reaction rate.

3.2 Applicability

The delayed amine catalyst A400 is suitable for the production of various types of polyurethanes, including rigid foams, soft foams, elastomers, coatings, adhesives, etc. Its delayed catalytic effect is particularly suitable for large-scale production, which can effectively avoid violent heat exogenous in the early stage of the reaction and reduce safety hazards in the production process.
