High-efficiency polyurethane foaming system based on trimerization catalyst TAP

Introduction

Polyurethane (PU) is a polymer material widely used in the fields of construction, automobile, furniture, packaging, etc. Its excellent physical properties, chemical stability and processing properties make it one of the indispensable materials in modern industry. Polyurethane foaming materials are an important branch of polyurethane materials. They have the characteristics of lightweight, heat insulation, sound insulation, and buffering. They are widely used in building insulation, cold chain transportation, automotive interiors and other fields.

The selection of catalyst is crucial during polyurethane foaming. Triamine-based Amine Polyol, as a highly efficient catalyst, has been widely used in polyurethane foaming systems in recent years. This article will introduce in detail the high-efficiency polyurethane foaming system based on trimerizing catalyst TAP, including its working principle, product parameters, application fields and advantages.

1. Working principle of trimerization catalyst TAP

1.1 Basic principles of polyurethane foaming

Polyurethane foaming is a process in which polyurethane is produced through the chemical reaction between isocyanate and polyol (Polyol), and at the same time, carbon dioxide gas is released to form a foam structure. This process mainly includes the following steps:

Gel Reaction: Isocyanate reacts with polyols to form polyurethane.
Foaming reaction: Isocyanate reacts with water to form carbon dioxide gas, forming foam.
Crosslinking reaction: Isocyanate reacts with polyols or water to form a crosslinking structure, improving the mechanical properties of the foam.

1.2 The mechanism of action of trimerization catalyst TAP

Trimerization catalyst TAP is an amine catalyst based on the triazine structure and has the ability to efficiently catalyze the reaction of isocyanate with polyols. Its mechanism of action mainly includes the following aspects:

Accelerating gel reaction: TAP can significantly accelerate the reaction between isocyanate and polyol, shorten the gel time and improve production efficiency.
Control foaming reaction: TAP can effectively regulate the reaction rate of isocyanate and water, and control the density and pore size distribution of the foam.
Promote cross-linking reaction: TAP can promote the cross-linking reaction of isocyanate with polyol or water, and improve the mechanical properties and stability of foam.
