Abstract

The invention discloses a wear-resistant tear-resistant ethylene propylene diene monomer rubber material which is prepared from the following raw materials in parts by weight: 30-40 parts of ethylene propylene diene monomer rubber, 10-18 parts of chloroprene rubber, 0.8-1.5 parts of LH-C96 vulcanizing agent, 0.5-1.5 parts of N,N'-m-phenyl bismaleimide, 1.5-1.8 parts of accelerator TMTD (tetramethyl thiuram disulfide), 2-4 parts of magnesium oxide, 1-3 parts of stearic acid, 5-10 parts of trioctyl trimellitate, 2.5-4 parts of environment-friendly flame retardant FR-T801, 0.8-1.6 parts of antimony trioxide, 20-40 parts of nano zinc oxide, 15-30 parts of coal gangue powder, 20-30 parts of calcined argil, 2-3 parts of anti-aging agent RD and 0.5-1.3 parts of anti-aging agent NBC. The material has the advantages of excellent wear resistance, excellent wear resistance and favorable aging resistance.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a wear-resistant and tear-resistant EPDM material. Background technique [0002] EPDM rubber is a terpolymer of ethylene, propylene and non-conjugated diene. Diene has a special structure. Only one of the two bonds can be copolymerized. The unsaturated double bond is mainly used as a cross-link. An unsaturated one will not become the main polymer chain, but only the side chain, so that the main polymer chain of EPDM rubber is completely saturated. This property makes EPDM resistant to heat, light, oxygen, and especially ozone. EPDM rubber is non-polar in nature, resistant to polar solutions and chemicals, has low water absorption, and has good insulating properties. EPDM has the lowest specific gravity of all rubbers and can absorb large amounts of fillers and oils with little effect on properties, making it possible to make inexpensive rubber compounds. Due to its ex...
