Background
In interior decoration, wood materials are mainly used. With the increasing requirements of indoor acoustic environment, the sound insulation performance of the wood material has certain requirements. The sound insulation performance of the wood material is mainly influenced by the surface density and the thickness, and the sound insulation performance of the board is increased along with the increase of the surface density. The traditional method for improving the sound insulation performance of the single-board material is to increase the thickness and the surface density of the material, however, the method has certain limitation and is not beneficial to the long-term development of the single-board sound insulation material. The novel sound insulation material mainly adopts a multilayer composite material, and develops towards the direction of light weight and thin thickness, and the sound insulation performance of the obtained multilayer composite material is superior to that of a single-layer plate with the same thickness and surface density.
The multilayer composite material contains a large number of micropore structures, and the sound absorption and sound insulation performance is greatly superior to that of a complete solid structure because the speed (340 m/s) of sound in air is far less than the speed (3800 m/s) of sound in solid.
The types of the high polymer damping materials are more, and the research on the polyurethane damping materials and the rubber damping materials is deeper at present. Butyl rubber is commonly used as a damping noise reduction material in the market, and the loss peak of the composite damping material prepared by taking the butyl rubber as a matrix lasts from-70 ℃ to 20 ℃, so that the composite damping material is a damping material with a wider effective damping area.
