Background
The damping pad has wide application in the automobile damping technology, and the damping technology achieves the aim of damping by attaching high-damping paint on the surface of a structural member and dissipating the energy of the structural member. Damping pads generally include asphalt-based damping pads and rubber-based damping pads.

Asphalt damping pad is a good vibration-damping paint, and has more fiber substances in the horizontal direction inside. When the sheet metal structure vibrates, the internal friction force is necessary to absorb a great amount of kinetic energy due to the crisscross arrangement of the fiber materials, so that the effects of vibration reduction and damping are achieved. However, the typical damping pad has poor high temperature resistance and is easy to adhere to the carpet under high temperature conditions, so that a high temperature resistant heat insulation damping pad is needed.
