Abstract

The invention discloses a sheet adhesive for sound attenuation and noise reduction of a car door. The sheet adhesive is prepared from the following components in parts by weight: 30-40 parts of synthetic rubber, 3-10 parts of softening agent, 5-15 parts of tackifier, 10-25 parts of sound attenuation filling agent, 2-8 parts of viscosity stabilizer, 4-10 parts of flame retardant, 5-10 parts of reinforcing filler and 0.1-5 parts of anti-aging agent. The adhesive is a non-curing type sheet, cannot change in state when placed at normal temperature for 12 months, has adhesive force with oil steel plate and galvanized steel plate substrates, and is adhered to the car door to eliminate noise generated in the car driving process. In addition, the addition of the viscosity stabilizer can improve the application temperature of the adhesive, so that the adhesive has good initial adhesion force at 0-40 DEG C. The adhesive has the advantages of having good adhesion property with the oil steel plate and galvanized steel plate substrates, and is suitable for the sound attenuation and noise reduction of the car door.

Description

technical field [0001] The invention relates to sound-absorbing and noise-reducing materials, in particular to a sheet-shaped adhesive used for noise-reducing and noise-reducing car doors. Background technique [0002] In recent years, adhesives and damping materials have attracted more and more attention. For example, in the automobile industry, with the requirement of light weight of automobiles, the steel plates used in automobile bodies are becoming thinner and thinner, so that high-speed airflow will be generated when the automobile is running at high speed, which will bring strong noise and vibration to passengers and drivers. Therefore, noise-absorbing and noise-reducing materials with light weight, good adhesion, sound absorption and vibration reduction are more and more widely used in the automotive industry, and the requirements are getting higher and higher. Generally, OEMs solve the noise problem by sticking reinforcing film on the door and other weak parts. Alt...
