Wear-resistance rubber for vehicles

Abstract

The invention discloses wear-resistance rubber for vehicles. The wear-resistance rubber is prepared from the following components in parts by weight: 20-45 parts of neoprene, 15-45 parts of nitrile rubber, 3-6 parts of vulcanizer, 4-9 parts of accelerant, 5-12 parts of an anti-aging agent, 3-15 parts of plasticizer, 6-10 parts of zinc oxide, 5-9 parts of stearic acid, 9-12 parts of glass fiber, 3-7 parts of silicon dioxide, 2-5 parts of sodium urea formaldehyde polymer, 2-5 parts of sulfur and 3-6 parts of carbon black. Compared with the prior art, the wear-resistance rubber has the advantages that the sodium urea formaldehyde polymer and glass fibers are added into rubber to increase the wear resistance, so that the wear resistance of the rubber is greatly improved; and meanwhile, metal wires are contained inside the rubber, and the effect of absorbing sounds can be achieved.

Description

technical field [0001] The invention relates to the field of automotive rubber materials, in particular to a wear-resistant rubber for vehicles. Background technique [0002] There are relatively many rubber parts on the car, most of which are used to seal the windows and shock absorbing parts. On the one hand, it has the function of waterproofing, and on the other hand, it has the functions of sound insulation, shock absorption and buffering. With the prolongation of the service time of the vehicle, these rubber parts will gradually harden, age or even crack. Once the above phenomenon occurs, it will cause poor sealing, which will not only fail to resist wind and rain, reduce the comfort of the vehicle, but also cause labor hours during maintenance. The cost and material cost are high. Although natural rubber has the advantages of good elasticity, high strength and good comprehensive performance, natural rubber is expensive and costly. Moreover, natural rubber has poor ozon...

Problems solved by technology

With the prolongation of the service time of the vehicle, these rubber parts will gradually harden, age or even crack. Once the above phenomenon occurs, it will cause poor sealing, which will not only fail to resist wind and rain, reduce the comfort of the vehicle, but also cause labor hours during maintenance. The cost and material cost are high. Although natural rubber has the advantages of good elasticity, high strength and good comprehensive performance, natural rubber is expensive and costly. Moreover, natural rubber has poor ozone resistance and aging resistance, and its wear resistance is also poor. Not very ideal, need a rubber material with better wear resistance
