Problems solved by technology

[0002] Although natural rubber raw rubber has better elasticity, the edge tearing effect of the product is poor. At present, fillers such as calcium carbonate, talcum powder, carbon black are added in natural rubber, as the patent No. is a kind of rubber composition disclosed by CN1407007A, although The edge tearing effect is improved to a certain extent, but the rubber elasticity decreases more obviously, and there will be permanent white spots and marks on the surface of the hand-scratched product, and the stability of the product size is also affected.

Abstract

The invention discloses a high-elasticity rubber composition which comprises, by weight, 80-85 parts of natural rubber, 20-25 parts of batching rubber, 45-55 parts of fillers, 1-2 parts of accelerators, 1-2 parts of vulcanizing agents, 3-5 parts of zinc oxide, 0.5-1 part of stearic acid, 1-2 parts of anti-aging agents, 4-5 parts of oil and 1-2 parts of paraffin, wherein the batching rubber is mixture of styrene butadiene rubber and butadiene rubber. The rubber composition has high elasticity, high breaking strength and good edge tearing effect, products are stable in size, and white dots and marks cannot be generated when surfaces of the products are scraped by hands.

Description

technical field [0001] The invention belongs to the field of rubber and relates to a high elastic rubber composition. Background technique [0002] Although natural rubber raw rubber has better elasticity, the edge tearing effect of the product is poor. At present, fillers such as calcium carbonate, talcum powder, carbon black are added in natural rubber, as the patent No. is a kind of rubber composition disclosed by CN1407007A, although The tearing effect is improved to a certain extent, but the rubber elasticity decreases more obviously, and there will be permanent white spots and marks on the surface of the hand-scratched product, and the stability of the product size is also affected. Contents of the invention [0003] The object of the present invention is to provide a high-elasticity rubber composition which solves the above-mentioned defects existing in the existing rubber. It has high elasticity, good edge tearing effect, stable product size, and no white spots and...
