Novel sound-proof building material and preparation method thereof

Abstract

The invention discloses a novel sound-proof building material and a preparation method thereof and relates to the technical field of novel building materials. The novel sound-proof building material is prepared from raw materials in parts by weight as follows: 30-45 parts of polyethylene, 28-36 parts of polybutadiene rubber, 15-24 parts of kaolin, 10-18 parts of asbestos, 8-17 parts of plant fiber, 12-20 parts of volcanic mud, 8-16 parts of hollow glass beads, 7-15 parts of glass fibers, 5-9 parts of montmorillonite, 4-8 parts of nanometer oxide, 8-13 parts of silica particles, 10-16 parts ofpolyurethane resin particles, 4-9 parts of diatom ooze, 8-14 parts of calcium silicate, 4-7 parts of a foaming agent, 3-8 parts of an antioxidant, 4-7 parts of a flame retardant and 2-5 parts of a plasticizer. The novel sound-proof building material is light and easy to mount, has the advantages of stable chemical property, good sound absorbing effect and good flame retardance, can effectively weaken noise outside space, is low in raw material cost and has good market prospect.

Description

technical field [0001] The invention relates to the technical field of new building materials, in particular to a new sound-insulating building material and a preparation method thereof. Background technique [0002] With the development of social economy and the increase of industrial factories, vehicles and entertainment places, a large number of factory mechanical operation sounds, vehicle whistles and entertainment places are full of people's lives, causing a new type of pollution- sound polution. On the other hand, with the improvement of living standards, people have higher and higher requirements for the quiet and comfortable living environment, working and learning environment and public places. Therefore, how to control noise pollution and reduce the impact of noise on people's lives is an urgent problem to be solved at present. [0003] In the prior art, most of the sound insulation materials installed in home, business, transportation, etc. are heavy and dense m...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, most of the sound insulation materials installed in home, business, transportation, etc. are heavy and dense materials, such as steel plates, lead plates, brick walls, gypsum boards, etc., which are dense and without gaps. It is difficult to install and transport, and because this kind of sound insulation material is dense, it is difficult to absorb and transmit sound energy and has strong reflection, so the sound absorption effect of this kind of material is not ideal
