Abstract
The invention discloses packing leather cup rubber for hydraulic mount. The packing leather cup rubber is prepared from the following raw materials in parts by weight: 30-40 parts of nitrile rubber, 20-30 parts of isoprene rubber, 20-40 parts of ethylene propylene terpolymer 5962 (LANXESS Deutschland), 10-15 parts of fluorosilicone rubber, 3-5 parts of natural rubber, 20-30 parts of high abrasion furnace black N330, 10-15 parts of modified white carbon black, 3-4 parts of antimony trioxide, 8-10 parts of modified wood ash, 4-6 parts of attapulgite, 4-6 parts of meerschaum, 9-11 parts of modified iron tailing slag powder, 0.5-1 part of stearic acid, 0.5-1 part of vulcanizing agent TMT, 0.2-0.4 part of accelerant DM, 0.3-0.6 part of accelerant BZ, 1-2 parts of calcium stearate, 2-4 parts of zinc oxide, 0.2-0.4 part of ferrocene, 1-2 parts of polyethylene wax, 1-2 parts of triphenyl phosphite, 1-2 parts of anti-aging agent RD, 2-3 parts of vinyl-tris(beta-methoxyethoxy)silane and 16-18 parts of butyl epoxy oleate. The rubber disclosed by the invention has excellent ozone resistance, excellent low temperature resistance and heat resistance and is large in operating temperature range and environment-friendly in process, so that the rubber can be used for preparing various packing materials.
Description
technical field [0001] The invention relates to the field of synthetic rubber, in particular to a sealing cup rubber for hydraulic suspension and a preparation method thereof. Background technique [0002] Rubber cups mainly refer to rubber seals used in hydraulic brake systems, clutch control systems, and booster pump systems of cars, light vehicles, vans, and some trucks to transmit pressure and seal. Rubber cups are also used in household appliances, such as the rubber cups used on the cylinder body of a double-tub washing machine to seal the cylinder body. Rubber cups are one of the rubber products with wide application and important functions in rubber products. [0003] Main features of rubber cups: [0004] 1) The cups in the master cylinder and wheel cylinder must have certain elasticity, compression deformation and wear resistance, so as to ensure that the cups have a certain return ability and sealing ability to transmit hydraulic pressure during use. 2) It has...
