Abstract

The invention relates to the technical field of rubber products, particularly to a cold-resistant rubber, which comprises: 40-75 parts of rubber, 15-35 parts of carbon black, 5-15 parts of sulfur, 2-12 parts of pot clay, 5-12 parts of a plasticizer, and 3-12 parts of white carbon black. The cold-resistant rubber of the present invention has advantages of excellent cold resistance and long servicelife.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to cold-resistant rubber. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force. After removing the external force, it can return to its original shape. Rubber is a completely amorphous polymer. Its glass The transformation temperature is low, and the molecular weight is often very large, greater than hundreds of thousands. Early rubber was latex taken from plants such as rubber trees and rubber grasses, which were processed into materials with elasticity, insulation, impermeability to water and air. Rubber products are widely used in all aspects of industry or life. General-purpose rubber has good comprehensive properties and is widely used. It mainly includes: natural rubber, isoprene rubber, styrene-butadiene rubber, but...
