Abstract

The invention discloses a tear-resistant rubber material which is prepared from the following raw materials in parts by weight: 30-50 parts of chloroprene rubber, 15-22 parts of styrene-butadiene rubber, 3-8 parts of an antioxidant, 6-11 parts of highly dispersible silica, 6-8 parts of modified fly ash, 6-11 parts of an antioxidant RD, 5-7 parts of N220 reinforcing carbon black, 7-14 parts of octylphenolic resin, 2-6 parts of a silane coupling agent, 0.2-2 parts of dicumyl peroxide, 6-8 parts of nano-alumina, 3-5 parts of 2-mercaptoimidazoline, 2-4 parts of a scorch retarder, 5-9 parts of antimonous oxide, 4-7 parts of activated zinc oxide, 4-8 parts of carbon black N100. The tear-resistant rubber material has the benefits of being good in toughness and capable of resisting torsion and shear force and preventing the rubber from tearing.

Description

technical field [0001] The present invention relates to a tear-resistant rubber material. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. Rubber provides various rubber parts for mining, transportation, construction, machinery, electronics and other heavy industries. In heavy industry, good strength and comprehensive performance are required, especially in some high-torque heavy industries, most of the rubber materials are prone to tearing, which will lead to the scrapping of rubber parts. If they are not replaced in time, it may even cause safety problems. ACCIDENT. Therefore, in heavy industry, not only rubber is required to have good compression resistance and abrasion resistance, but also rubber is required to have good tear resistance and be able to withstand large torsion and shearing forces. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the problem to be solved by...
