Abstract

The invention discloses modified anti-tear rubber. The rubber is prepared from the following raw materials in parts by weight: 9 to 11 parts of stearic acid, 4 to 8 parts of butadiene-styrene rubber, 15 to 21 parts of chloroprene rubber, 6 to 10 parts of N115 reinforcing carbon black, 2 to 5 parts of a dispersing agent, 14 to 20 parts of tetrafluoroethlene propylene rubber, 7 to 10 parts of magnesium stearate, 3 to 10 parts of acrylate copolymer, 10 to 16 parts of epoxidized natural rubber, 1 to 5 parts of sulphur, 10 to 16 parts of zinc diethyl dithiocarbamate, 4 to 7 parts of sodium stearate, 1 to 3 parts of paste ash, 1 to 3 parts of an antifungus agent, and 13 to 20 parts of butadiene-acrylonitrile rubber. The rubber has the benefits that the rubber has good toughness and strength, good anti-tear property and good compression resistance.

Description

technical field [0001] The present invention relates to an improved tear-resistant rubber. 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 b...
