Abstract

The invention provides a resonance damping material produced by using waste rubber, which comprises the following raw materials in percentage by weight: 5 to 20% of butyl rubber, 2 to 15% of reclaimed butyl rubber, 5 to 20% of rubber oil, 2 to 15% of isobutene, 1 to 10% of white carbon black, 0.1 to 5% of carbon black, and 50 to 80% of powdered iron. The resonance damping material produced by using waste rubber can well resist high temperature because of reasonable selection and ratio of raw materials. Tests prove that the damping material can run for a regular time at a high temperature of 150 DEG. In addition, the damping material obtained by the invention has high waterproof performance and high adhesive strength as well as strong shock and noise absorbing performance.

Description

technical field [0001] The invention relates to the field of automobile brake system materials, in particular to a damping sheet material for preventing resonance produced by using waste rubber. Background technique [0002] The function of the damping sheet is to reduce shock, that is, to reduce the damage to the car body caused by the vibration of the engine during operation, mainly to reduce the possibility of resonance and prevent damage to the car body by the rigid connection, and to reduce noise, that is, to reduce the rigid connection. Causes noise transmission or amplification to the vehicle body. Conventional damping sheets for automobiles or air conditioners on the market, although there are a variety of raw materials, cannot meet high performance standards at low cost and low investment. Therefore, the raw materials and proportions of automobile or air-conditioning damping sheets and the performance indicators that can be achieved have become common problems that...
