Description

Technical Field

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature (Tg). Its molecular weight is often large, greater than hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry and life.

[0003] After the existing rubber is mixed, it is usually necessary to perform a sheeting operation so that the mixed rubber can maintain a certain shape, which can facilitate the storage of the rubber. However, the existing mixed rubber is prone to insufficient cooling during the sheeting process, and parts of the rubber are prone to adhere to the structure in contact with it, which makes the surface of the rubber not smooth enough, the stacking of the rubber is not stable enough, and it is easy to cause pressure on the rubber finishing.
