The key role of high-activity reactive catalyst ZF-10 in the production of high-performance polyurethane foams

Introduction

Polyurethane foam is a polymer material widely used in construction, automobile, furniture, packaging and other fields. Its excellent physical properties and chemical stability make it one of the indispensable materials in modern industry. However, the production process of polyurethane foams is complex and involves a variety of chemical reactions, in which the selection and use of catalysts have a critical impact on the performance of the final product. This article will introduce in detail the key role of the highly active reactive catalyst ZF-10 in the production of high-performance polyurethane foam, including its product parameters, mechanism of action, application cases and future development trends.

1. Basic concepts of polyurethane foam

1.1 Definition 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. Rigid foam is mainly used in the fields of building insulation, cold storage heat insulation, etc.; soft foam is widely used in furniture, mattresses, car seats, etc.; semi-rigid foam is between the two and is often used in automotive interiors, packaging materials, etc.

1.2 Production process of polyurethane foam

The production process of polyurethane foam mainly includes the following steps:

1. Raw material preparation: Select suitable raw materials such as polyols, isocyanates, catalysts, foaming agents, stabilizers, etc.
2. Mix: Mix the raw materials such as polyols, isocyanates, catalysts, etc. in a certain proportion.
3. Foaming: A gas is generated through chemical reactions, which causes the mixture to expand to form foam.
4. Currect: The foam forms a stable three-dimensional network structure during the curing process.
5. Post-treatment: Cut, mold, surface treatment, etc. of the foam.

2. The role of catalysts in the production of polyurethane foam

2.1 Mechanism of action of catalyst

The role of catalysts in the production of polyurethane foam is mainly to accelerate the chemical reaction between polyols and isocyanates, control the reaction rate, and adjust the density, hardness, elasticity and other properties of the foam. The selection and use of catalysts have a crucial impact on the performance of the final product.

2.2 Classification of catalysts

Catalytics can be divided into the following categories according to their chemical properties and mechanism of action:

1. Amine catalysts: such as triethylamine, dimethylMajor amines, etc., are mainly used to accelerate the reaction between isocyanates and polyols.
2. Metal catalysts: such as organic tin, organic lead, etc., are mainly used to accelerate the reaction of isocyanate and water, generate carbon dioxide gas, and expand the foam.
3. Composite Catalyst: It is composed of multiple catalysts, with synergistic effects and can accelerate multiple reactions at the same time.

2.3 Principles for selecting catalysts

When selecting a catalyst, the following factors should be considered:

1. Reaction rate: The catalyst should be able to effectively accelerate the reaction, but too fast or too slow reaction rate will affect the performance of the foam.
2. Foam Performance: The catalyst should be able to adjust the density, hardness, elasticity and other properties of the foam to meet different application needs.
3. Environmentality: The catalyst should have good environmental protection properties, contain no harmful substances, and comply with relevant environmental protection regulations.
4. Economic: The catalyst should have good cost-effectiveness and reduce production costs.
