Environment-friendly flame-retardant efficient nonwoven acoustic foam

Abstract

The invention relates to acoustic foam, in particular to environment-friendly flame-retardant efficient nonwoven acoustic foam comprising a top layer, a back layer, and a fiber bulk layer between the top layer and the back layer. Both the top layer and the back layer are made of nonwoven. The nonwoven is made with, by weight, 100 parts of isotactic polypropylene, 2-3 parts of decabromodiphenylethane, 3-4 parts of antimonous oxide, 1-2 parts of calcium stearate, 1-2 parts of methyl cellulose ether, 6-8 parts of cassava starch, 2-3 parts of triphenyl phosphate, 12-15 parts of epoxy fatty acid butyl ester, 3-5 parts of peony root, 1-2 parts of tea tree root, 2-3 parts of burdock, 1-2 parts of light yellow Sophora root, 2-3 parts of scandent hop, 1-2 parts of peach blossom, and 4-5 parts of aid. The environment-friendly flame-retardant efficient nonwoven acoustic foam with the outer layer of soft, solid, fireproof and flame-retardant nonwoven has the advantages of environmental friendliness, safety, capability of absorbing noise and reducing noise and the like and has promising application prospect.

Description

technical field [0001] The invention relates to a sound-absorbing cotton, in particular to an environmentally friendly and highly efficient flame-retardant non-woven sound-absorbing cotton. Background technique [0002] Sound-absorbing cotton is a kind of material that combines sound absorption and noise reduction, sound quality control and decoration. It is widely used in homes, concert halls, cinemas, automobiles, factories and other places. The traditional sound-absorbing cotton materials are mainly glass fiber and polyester fiber. , rock wool, mineral wool and other materials, however, the sound-absorbing cotton made of these materials has certain defects, such as poor environmental protection, carcinogenicity, flammability, poor water absorption, short service life, etc. Therefore, it is necessary to improve the original sound-absorbing cotton material , to improve its environmental protection and safety, and improve user experience; non-woven fabrics are undoubtedly an...

[0002] Sound-absorbing cotton is a kind of material that combines sound absorption and noise reduction, sound quality control and decoration. It is widely used in homes, concert halls, cinemas, automobiles, factories and other places. The traditional sound-absorbing cotton materials are mainly glass fiber and polyester fiber. , rock wool, mineral wool and other materials, however, the sound-absorbing cotton made of these materials has certain defects, such as poor environmental protection, carcinogenicity, flammability, poor water absorption, short service life, etc. Therefore, it is necessary to improve the original sound-absorbing cotton material , to improve its environmental protection and safety, and improve user experience; non-woven fabrics are undoubtedly an ideal alternative material, which has the advantages of moisture-proof and flame-retardant, flexible, lightweight, good air permeability, recyclable, non-toxic and harmless, etc. Cooperating with other sound-absorbing materials, it can effectively improve the defects of existing sound-absorbing cotton, and improve sound-absorbing and sound-insulating effects
