Abstract

The invention discloses a high tensile strength rubber material, which is prepared from the following raw materials in parts by weight: 40-60 parts of hydrogenated nitrile rubber, 15-25 parts of epichlorohydrin rubber, 20-40 parts of ethylene propylene diene monomer, 0.5-1 part of epoxy fatty acid methyl ester, 1-2 parts of trioctyl phosphate, 1-2 parts of chlorinated paraffin, 10-20 parts of modified humic acid, 8-22 parts of carbon fibers, 10-18 parts of anthracite, 2-8 parts of sodium antimonate, 5-12 parts of antimony trioxide, 0.5-1.5 parts of epoxidized soybean oil, 0.1-0.6 part of trimethyl phosphate, 1-2 parts of microcrystalline wax, 1-3 parts of an antioxidant DNP, 0.5-1.5 parts of di-tert-butyl peroxide, 1-2 parts of hexahydrophthalic anhydride and 1-2 parts of sulphur. The high tensile strength rubber material has very good hardness, toughness and tensile strength as well as very high density, is excellent in corrosion resistance and ageing resistance, and has higher impact resistance.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber material with high tensile strength. Background technique [0002] my country is a big country in the rubber industry in the world. With the rise of the global low-carbon economy, green manufacturing has become one of the strategic guidelines for the sustainable development of my country's rubber industry. In order to increase industrial restructuring and vigorously develop safe, energy-saving and environmentally friendly raw materials is green basis of manufacture. In order to meet the performance requirements of parts, for example, the engine bracket made of skeleton and rubber bonding requires high hardness and tensile strength, while the hardness and tensile strength of natural rubber are low, making the gap between the rubber and the skeleton The bonding strength is poor, and the manufactured engine bracket cannot meet the demand and needs to be improved urgently. ...
