Classification of rubber accelerators and the concept of five systems

I. Definition of rubber accelerator

Rubber accelerator is a kind of high elastic polymer compounds (molecular weight is generally more than 100,000), so there is no high elasticity of other materials, so it is also called elastomer.

Rubber accelerator manufacturers

Two, the basic characteristics of rubber accelerator

1. Elasticity

2. It has the function of shock absorption and buffering

3. Large dependence on temperature

4, with electrical insulation

5, there is aging phenomenon

6, small proportion, low hardness, good softness

Three, raw rubber natural rubber sources

1. Wild rubber: rubber harvested from wild trees and plants;

2, cultivation of rubber: mainly three leaf rubber tree;

3, rubber grass rubber: one hectare can harvest 150-200KG;

4. Gutta-percha: Extracted from the branches and roots of Duzhong Tree. No elasticity at room temperature, high softening point, heavy ratio, good water resistance.

Four, five systems composed of formula

1. Main material

2. Softening growth rate system:

Reduce the viscosity of the compound, improve the processing property, reduce the hardness of the finished product.

3. Vulcanization system

The rubber linear large house is crosslinked to form a spatial network structure to improve performance and stabilize shape.

4. Reinforcing and filling system

Improve rubber mechanical properties, improve processing properties, reduce costs.

5. Protection system

Delay rubber aging, prolong the service life.
