Tear-resistant and good-leakproofness tire rubber material

Abstract

The invention discloses a tear-resistant and good-leakproofness tire rubber material. The tear-resistant and good-leakproofness tire rubber material is prepared from, by weight, 15-25 parts of nitrile rubber, 4-12 parts of polybutadiene rubber, 20-35 parts of butadiene styrene rubber, 6-12 parts of chlorosulfonated polyethylene rubber, 0.5-1.7 parts of antioxidant A, 0.5-1.5 parts of oleic acid, 0.5-2.5 parts of stearic acid, 0.15-0.45 part of ammonium dichromate, 2-4 parts of dibenzothiazyl disulfide, 30-50 parts of modified bamboo fiber, 4-12 parts of nano-carbon black, 8-16 parts of nano-cellulose whiskers, 45-65 parts of nano-clay, 3-12 parts of corn straw fiber, 1-2 parts of octyl-phenolic tackifying resin, 4-12 parts of bamboo residue fiber, 0.4-1.6 parts of dibutyl phthalate, 0.7-1.3 parts of dioctyl sebacate and 0.6-1.2 parts of epoxy fatty acid methyl ester. The tear-resistant and good-leakproofness tire rubber material is good in rear resistance and anti-aging performance and excellent in sealing performance.

Description

technical field [0001] The invention relates to the technical field of rubber tires, in particular to a tire rubber material with good tear resistance and sealing performance. Background technique [0002] Now the rubber industry is one of the important basic industries of the national economy. It not only provides people with daily and medical light industrial rubber products that are indispensable in daily life, but also supplies heavy and emerging industries such as mining, transportation, construction, machinery, and electronics. Provide all kinds of rubber production equipment or rubber parts. Rubber is more and more widely used, but there are still some defects, because in recent years, with the increase of cars, the amount of rubber is increasing, and the quality of tires is also increasing. However, tires are often used under complex and harsh conditions, and they are subjected to various extrusion, friction and high temperatures while driving. At present, ordinary r...

[0002] Now the rubber industry is one of the important basic industries of the national economy. It not only provides people with daily and medical light industrial rubber products that are indispensable in daily life, but also supplies heavy and emerging industries such as mining, transportation, construction, machinery, and electronics. Provide all kinds of rubber production equipment or rubber parts. Rubber is more and more widely used, but there are still some defects, because in recent years, with the increase of cars, the amount of rubber is increasing, and the quality of tires is also increasing. However, tires are often used under complex and harsh conditions, and they are subjected to various extrusion, friction and high temperatures when driving. At present, ordinary rubber tires cannot meet the demand and need to be solved urgently
