Description

Technical field

[0001] The invention relates to a sound insulation and deodorant interlayer for automobile interior decoration. Background technique

[0002] With the development of science and the rise of people's material levels, noise pollution has become a problem that cannot be ignored. The absorption and reduction of noise pollution has become an important issue for the coordinated development of human society. With the deepening of research, various materials that absorb sound waves are produced. The principle of sound insulation is to use when sound waves pass through a certain object, the object can absorb, weaken the reflection and even block the continued propagation of sound waves, so as to achieve the effect of sound insulation. With the development of the automobile industry, the requirements for sound insulation, heat resistance and mechanical properties of sound insulation materials are getting higher and higher. Therefore, the requirements for sound insulation m...
