Problems solved by technology

At present, the vibration damping pad is relatively affected by the environmental climate because it is often exposed to the air.
At the same time, with the movement of the car, great pressure will be generated on the radial surface of the shock absorbing pad, which will easily cause deformation, aging or even cracking of the shock absorbing pad, thereby affecting the vibration damping effect and causing the vehicle to vibrate. Even frequent replacement of shock absorbing pads will increase the cost and cause inconvenience to users
At the same time, the vibration damping pad made of rubber is easy to crack due to the heat generated by friction during use, which is not conducive to the service life of the rubber vibration damping pad.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a wear-resistant and vibration-damping pad material for automobiles and a preparation method thereof. Background technique [0002] Vibration-absorbing rubber products achieve the purpose of shock absorption by absorbing or reducing the vibration generated by movement through the high damping effect of the product. Vibration-absorbing pads are the most common vibration-damping rubber products. For example, when an automobile engine is working, the reciprocating motion of the piston in the cylinder, the combustion of fuel in the cylinder, and the movement of other moving parts with the piston rod will cause the engine to vibrate violently. If the engine is directly connected to the chassis, the chassis will also vibrate, affecting the handling and comfort of the car. The vibration damping pad is installed between the automobile engine and the chassis to absorb the vibrat...
