The mechanism of regulation of reactive activity of amine catalyst A400 on polyurethane

Mechanism for the regulation of the reactive activity of amine catalyst A400 on polyurethane

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 synthesis of polyurethane involves complex chemical reactions, where the selection of catalysts has a critical impact on the reaction rate and the performance of the final product. As a highly efficient catalyst, the retardant amine catalyst A400 can significantly regulate the reactivity of polyurethane and thus optimize the performance of the product. This article will discuss in detail the regulation mechanism of delayed amine catalyst A400, and introduce its product parameters and applications.

2. Basic principles of polyurethane reaction

The synthesis of polyurethane mainly involves the reaction between isocyanate and polyol (Polyol). The reaction is usually divided into two stages:

Prepolymer formation stage: Isocyanate reacts with polyol to form prepolymers, and the reaction rate is relatively fast in this stage.
Crosslinking and curing stage: The prepolymer further reacts to form a three-dimensional network structure, and the reaction rate is slower at this stage.

The role of catalysts in polyurethane reaction is mainly to accelerate the reaction rate of isocyanate and polyol, thereby shortening the reaction time and improving production efficiency. However, too fast reaction rates may lead to uneven reactions, affecting the performance of the final product. Therefore, it is crucial to choose the right catalyst.

3. Overview of Retarded Amine Catalyst A400

The delayed amine catalyst A400 is a highly efficient polyurethane reaction catalyst with the characteristics of delayed reaction activity.

At the early stage of the polyurethane reaction, A400 has a low catalytic activity, mainly because the retardant groups in its molecular structure form a stable intermediate with isocyanate at the beginning of the reaction, thereby reducing the catalytic activity. This delay effect prolongs the initial time of the reaction, which is conducive to sufficient mixing of reactants and improving the uniformity of the reaction.

4.2 Acceleration effect in late stage of reaction

As the reaction progresses, the delay groups in the A400 molecular structure are gradually consumed and the catalytic activity is gradually enhanced. At this time, A400 can effectively accelerate the reaction rate between isocyanate and polyol and promote the cross-linking and curing process. This acceleration effect shortens the late reaction time and improves production efficiency.

4.3 Effect of temperature on catalytic activity

Temperature is an important factor affecting the catalytic activity of A400. At lower temperatures, A400 has a lower catalytic activity and a significant delay effect; while at higher temperatures, A400 has a significantly enhanced catalytic activity and a significant acceleration effect. Therefore, in practical applications, the catalytic activity of A400 can be controlled by adjusting the reaction temperature, thereby optimizing the reaction process.

4.4 Effect of catalyst dosage

Dose of A400The urethane reaction rate and final product performance have important effects. An appropriate amount of A400 can effectively adjust the reaction rate and improve the performance of the product; while an excessive amount of A400 may lead to excessive reaction rate and affect the uniformity of the product. Therefore, in practical applications, it is necessary to select the appropriate amount of A400 according to the specific reaction system.
