Abstract

The invention belongs to the technical field of rubber, and in particular relates to ultra-light high-wear-resistant rubber and a preparation process thereof. The ultra-light high-wear-resistant rubber includes 100-120 parts of epoxidized natural rubber, 50-80 parts of butyl rubber, 50-60 parts of chlorinated polyethylene rubber, 5-10 parts of modified nano silicon dioxide, 10-20 parts of diatomite, 2-5 parts of carboxymethyl cellulose sodium, 20-30 parts of carbon black, 10-15 parts of paraffin, 10-15 parts of graphite powder, 1-3 parts of a flame retardant, 0.5-3 parts of an anti-aging agent, 2-4 parts of a vulcanizing agent and 0.5-2 parts of a vulcanizing aid. The butyl rubber and the natural rubber are blended for use, so that the processability of the butyl rubber is improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of resins, and in particular relates to an ultra-light and highly wear-resistant rubber and a preparation process thereof. Background technique [0002] Rubber is a highly elastic, reversibly deformable polymer that can be obtained from the sap of some plants (natural rubber) or man-made (synthetic rubber). It is made after solidification and drying, and the finished product after processing is a material with elasticity, insulation, impermeability to water and air. Synthetic rubber is obtained by polymerization of various monomers. Common rubber on the market is divided into natural rubber, general rubber, styrene-butadiene rubber, nitrile rubber, silicone rubber, butadiene rubber, isoprene rubber, ethylene-propylene rubber, and neoprene. [0003] Rubber products are closely related to our life and have been widely used in all walks of life. Common rubber products in life include tires, tapes, rubber sho...
