High-efficiency polyurethane foaming system based on retardant amine catalyst C225

Introduction

Polyurethane (PU) is a polymer material widely used in construction, automobile, furniture, packaging and other fields. Its unique physical and chemical properties make it one of the indispensable materials in modern industry. Polyurethane foaming materials have been widely used in the fields of building insulation and automotive interiors due to their lightweight, thermal insulation, sound insulation and other characteristics. However, the traditional polyurethane foaming system has certain limitations in terms of reaction speed, foam uniformity, environmental protection, etc. To solve these problems, the delayed amine catalyst C225 was born and became a key component of the highly efficient polyurethane foaming system.

This article will introduce in detail the high-efficiency polyurethane foaming system based on the delayed amine catalyst C225, including its working principle, product parameters, application fields, advantages and challenges. Help readers fully understand this advanced technology through rich forms and easy-to-understand language.

1. Working principle of delayed amine catalyst C225

1.1 Basic principles of polyurethane foaming

Polyurethane foaming is a process in which polyols and isocyanate react to form polyurethane, and at the same time release carbon dioxide gas to form a foam structure. This process is usually divided into three stages:

Foaming stage: Polyol reacts with isocyanate to form carbamate, and at the same time releases carbon dioxide gas to form foam.
Gel stage: The foam structure gradually stabilizes, forming a three-dimensional network structure.
Currecting Stage: The foam is completely cured to form the final polyurethane foaming material.

1.2 The role of retardant amine catalyst C225

The delayed amine catalyst C225 is a highly efficient polyurethane foaming catalyst. Its main function is to regulate the rate of foaming reaction and ensure the uniformity and stability of the foaming process. Compared with traditional catalysts, C225 has the following characteristics:

Delay effect: C225 exhibits low catalytic activity at the beginning of the reaction. As the reaction progresses, the catalytic activity gradually increases, thus avoiding the problem of uneven foaming caused by excessive reaction.
High efficiency: C225 can achieve efficient catalysis at lower concentrations, reducing catalyst usage and reducing costs.
Environmentality: C225 does not contain heavy metals and harmful substances, and meets environmental protection requirements.

1.3 Chemical structure of retardant amine catalyst C225

The chemical structure of C225 is N,N-dimethylcyclohexylamine (DMCHA), and its molecular formula is C8H17N. DMCHA has a ring-like structure, which can form a stable complex at the beginning of the reaction, delaying catalytic activity. As the reaction progresses, the complex gradually dissociates, releases active catalysts, and accelerates the reaction.
