The role of coal pitch in reclaimed rubber

Reclaimed rubber is a rubber material that can be reused, and it can be rejuvenated and revitalized by processing and treating waste rubber. Coal pitch plays a very important role in the production of reclaimed rubber. This article will introduce in detail the role of coal pitch in reclaimed rubber.

First, the characteristics of coal asphalt.

Coal pitch is a material processed from coal tar, which has the following characteristics:

1.Good adhesion properties: Coal pitch has a high adhesion capacity, which can effectively bond different kinds of rubber materials together.

2.Aging resistance: Coal pitch has good aging resistance, which can effectively improve the durability of reclaimed rubber.

3.* Low price: The ** of coal pitch is relatively low, which can effectively reduce the production cost of reclaimed rubber.

Second, the role of coal pitch in reclaimed rubber.

In the production process of reclaimed rubber, coal asphalt mainly plays the following roles:

1.Binders: Coal pitch can be used as a binder to bond different kinds of rubber materials together. Its adhesive properties are better than natural rubber, which can effectively improve the strength and durability of reclaimed rubber.

2.Filler: Coal pitch can also be used as a filler to improve the physical properties of reclaimed rubber. It can increase the volume of reclaimed rubber, improve its hardness and heat resistance.

3.Softener: Coal pitch can also be used as a softener to improve the flexibility and elasticity of reclaimed rubber. It can increase the ductility and resilience of reclaimed rubber, making it more suitable for manufacturing various rubber products.

3. The effect of coal asphalt on the properties of reclaimed rubber.

In the production process of reclaimed rubber, the amount of coal pitch added has a great impact on the performance of reclaimed rubber. If the amount is added too much, it will lead to an increase in the hardness of the reclaimed rubber, affecting its flexibility and elasticityIf the amount is too small, it will lead to a decrease in the strength of the reclaimed rubber and affect its durability. Therefore, it is necessary to strictly control the amount of coal pitch added in the production process to achieve the best reclaimed rubber performance.

IV. Conclusions. Coal pitch plays a very important role in the production of reclaimed rubber, it can be used as a binder, filler and softener, which has a great impact on the performance of reclaimed rubber. By reasonably controlling the amount of coal pitch added, it is possible to produce reclaimed rubber with excellent properties. In the future, with the continuous improvement of environmental awareness and the increasing scarcity of resources, the demand for reclaimed rubber will be increasing, and the role of coal pitch in the production of reclaimed rubber will also be more widely used and concerned.
