Abstract

The invention discloses a polyvinyl chloride composite soundproof material. The polyvinyl chloride composite soundproof material comprises, by weight, 100 parts of polyvinyl chloride, 40 to 50 parts of ceramic wastes, 20 to 40 parts of floating beads, 5 to 8 parts of glyceryl monostearate, 2 to 3 parts of a plasticizer, 11 to 16 parts of a filler, 2 to 3 parts of a coupling agent, 4 to 7 parts of a stabilizer and 5 to 7 parts of a foaming agent. The invention also provides a preparation method of the polyvinyl chloride composite soundproof material. The polyvinyl chloride composite soundproof material has good sound insulation performances and processing performances and can be widely used for sound insulation of buildings.

Description

technical field [0001] The invention relates to the field of sound-insulating materials, in particular to a polyvinyl chloride composite sound-insulating material and a preparation method thereof. Background technique [0002] From a physical point of view, noise refers to some irregular and uncoordinated sounds, that is, a chaotic combination of sound waves with different sound intensities and frequencies. When the noise is relatively large, it will cause people's inner troubles, affect people's work, study and rest, and more seriously affect people's health, especially causing greater damage to hearing. Noise pollution is one of the four major pollutions today. The area of ​​noise pollution is large and can be seen everywhere. The harm caused by noise to people is increasing. Noise reduction has become a consensus among people. [0003] Sound wave is a kind of mechanical wave, which has very obvious wave characteristics during its propagation, which determines that reflec...
