Description

Technical Field

[0001] The utility model relates to the technical field of rubber production, in particular to a waste rubber softening device for rubber production. Background Art

[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 and a molecular weight that is often large, greater than hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed from gum extracted 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 or various aspects of life.

[0003] Waste rubber is usually recycled and reused. When processing waste rubber, it is first necessary to soften the rubber for subsequent processing. Existing waste rubber is generally softened by a melting box, which only has the function of melting.

Therefore, it is particularly important to improve the existing waste rubber softening device and design a new type of waste rubber softening device for rubber production to solve the above-mentioned technical defects and improve the practicability of the waste rubber softening device for overall rubber production.
