Abstract

The invention discloses a silencing composite board used for an automobile. The silencing composite board comprises a sound insulation substrate, a sound absorption layer and a sound absorption panel layer are sequentially arranged on the surface of the sound insulation substrate from bottom to top, the surface of the sound absorption panel layer is coated with a fire-proof coating, the top face of the sound absorption layer is in a concave-convex saw tooth shape, and an adhesive coating is arranged on the bottom face of the sound insulation substrate. The silencing composite board is installed in an assembly gap of the automobile and has a good sound absorption and noise reduction effect; particularly, the top face of the sound absorption layer is in the concave-convex saw tooth shape, in this way, the sound absorption area of the sound absorption layer can be greatly increased, and the noise reduction effect is improved; meanwhile, the surface of the sound absorption panel layer is coated with the fire-proof coating, so that safety performance is improved; in addition, the adhesive coating is arranged on the bottom face of the sound insulation substrate, in this way, the silencing composite board can directly adhere to the automobile as long as a packaging film of the silencing composite board is disclosed, and installing is convenient.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a sound-absorbing composite panel for automobiles. Background technique [0002] With the improvement of living standards, cars have entered thousands of households as a very common means of transportation. Due to the huge population base in China, the number of household cars is also very large. At the same time, with the development of technology, consumers have put forward higher requirements for the comfort performance of family cars. When the car is running, it will produce various noises, such as the sound of the engine running, the tire noise caused by the friction between the tires and the ground, and driving for a long time. These noises will seriously affect the comfort of the driver and passengers. Therefore, how to reduce the noise generated by the running of automobiles is an urgent problem to be solved in the industry. Contents of the invention [0003] The o...
