Abstract

The invention relates to the field of products of sound insulation material, solves the problems in the prior art that the sound insulation material is poor in sound insulation effect, is incomprehensive in high and low frequency sound insulation, causes pollution and is easy to age, and provides an efficient sound insulation material and a manufacturing method thereof. The efficient sound insulation material includes a sound insulation layer, a sound absorption layer, and a bubble layer, wherein the bubble layer is located between the sound insulation layer and the sound absorption layer. The sound absorption layer is made of a sound insulation compound, and the sound insulation compound is prepared by raw materials of the following substances: a thermoplastic resin, inorganic fillers, and a foaming agent, wherein the inorganic fillers account for 15-80wt%, the foaming agent accounts for 5-15wt%, and the rest is the thermoplastic resin. In the efficient sound insulation material, the fillers with different particle diameters correspond to sound waves of different wave bands or frequencies, and thus consumption of sound energy of different frequencies is relatively comprehensive, and the sound insulation effect is good, so the sound insulation material is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of sound-insulating material products, and relates to a high-efficiency, high-low-frequency sound-insulating comprehensive material and a manufacturing method thereof. Background technique [0002] With the development of modern industry, environmental pollution is also produced. Noise pollution is a kind of environmental pollution, which has become a great harm to human beings. Noise pollution, water pollution and air pollution are regarded as the three main problems of human life and living environment. [0003] Noise is an irregular sound emitted by a sounding body. The sound is caused by the vibration of an object and propagates in a certain medium (such as solid, liquid, gas) in the form of waves. The sound usually heard is air sound. Generally speaking, the frequency of sound waves that can be heard by the human ear is 20-20,000 Hz, which is called audible sound; below 20 Hz, it is called infrasound wave; abov...
