Abstract

The invention discloses a method for preparing a shock absorbing bushing rubber material, which comprises a rubber bushing body. The rubber material is prepared from the following components in partsby weight: 10 to 15 parts of chlorosulfonated polyethylene, 2 to 10 parts of an active agent, 2 to 3 parts of tackifying resin, 20 to 22 parts of carbon black, 5 to 15 parts of a softener, 20 to 25 parts of a reinforcing agent, 5 to 6 parts of ethoxyquinoline, and 1 to 4 parts of an accelerator. The rubber prepared by the formula disclosed by the invention has good heat-resistant air aging, good elongation rate and ozone resistance rate, and the metal and rubber combined shock absorbing bushing made of the material has high partial load capacity of rubber, the product quality of the shock absorbing bushing is improved, and the bushing has higher vibration absorption and cushioning performances. The rubber bushing body is arranged at the inner side of a cylindrical sleeve, the front and back ends of the cylindrical sleeve are fixedly provided with sealed fixing covers through screws, a combination and installation method is simple, and the disassembly and assembly are convenient.

Description

technical field [0001] The invention belongs to the technical field of shock-absorbing bush rubber materials, and in particular relates to a preparation method of shock-absorbing bush rubber materials. Background technique [0002] Because the rubber material itself has the advantages of light weight, impact resistance and high-frequency vibration absorption, coupled with the improvement of rubber and metal bonding technology, the metal rubber spring formed by the combination of metal and rubber, that is, rubber bushing, is widely used in automobile suspension. The support device in the frame is used to support the quality of the frame, ease the vibration and impact of uneven roads on the car, and quickly attenuate the vibration, improve driving comfort, reduce the dynamic stress of each part of the car body, and prolong the service life of the vehicle. [0003] The damping bushing combined with metal and rubber has certain performance requirements for rubber. There is still...
