Abstract

The invention discloses wear-resistant tear-resistant ethylene propylene diene monomer material rubber. According to the technical scheme, the wear-resistant tear-resistant ethylene propylene diene monomer material rubber comprises a main material and auxiliary materials, the main material comprises ethylene propylene diene monomer, and the auxiliary materials comprise thermoplastic elastomer, chlorosulfonated polyethylene, rubber compound, polyurethane resin, wear-resistant carbon black, a vulcanizing agent, a softener, an adhesive, an accelerator ZDC, a flame retardant, zinc oxide and sulfur. The softener is a mixture of vaseline, paraffin and asphalt. The wear-resistant and tear-resistant ethylene propylene diene monomer material rubber has the beneficial effects that the thermoplasticelastomer, the chlorosulfonated polyethylene, the rubber compound, the polyurethane resin and the wear-resistant carbon black are added according to a proper proportion, so that the tensile strength,the aging condition, the wear resistance and the tear resistance of the ethylene propylene diene monomer are greatly improved, the service life of the ethylene propylene diene monomer is prolonged, the use range of the ethylene propylene diene monomer is widened, and the flame retardant effect of the ethylene propylene diene monomer is effectively improved by adding the flame retardant.

Description

technical field [0001] The invention relates to the technical field of EPDM rubber, in particular to a wear-resistant and tear-resistant EPDM material rubber. Background technique [0002] EPDM is a terpolymer of ethylene, propylene and non-conjugated diene. The diene has a special structure, and only one of the two bonds can be copolymerized. The unsaturated double bond is mainly used as a cross-link, and the other Unsaturated will not become the main chain of the polymer, but will only become the side chain. The main polymer chain of EPDM is completely saturated. This feature makes EPDM resistant to heat, light, oxygen, especially ozone , EPDM is non-polar in nature, resistant to polar solutions and chemicals, has low water absorption, and has good insulating properties. In the production process of EPDM, by changing the amount of three monomers, The ratio of ethylene to propylene, the molecular weight and its distribution, and the method of vulcanization can adjust its c...
