Description

Crushing equipment for rubber elastic body processing

Technical Field

The invention relates to the technical field of rubber crushing, in particular to crushing equipment for processing rubber elastic body.

Background Art

The structural characteristics of thermoplastic elastomers are resin segments and rubber segments composed of different chemical bonds. The resin segment forms physical crosslinking points by virtue of the interchain force. The rubber segment is a highly elastic segment that contributes to elasticity. The physical crosslinking of the plastic segment changes reversibly with the change of temperature, showing the plastic processing characteristics of thermoplastic elastomers. Therefore, thermoplastic elastomers have the physical and mechanical properties of vulcanized rubber and the process processing properties of thermoplastic plastics. They are a new type of polymer material between rubber and resin, and are often called the third generation of rubber.
