Nonwoven cloth sound absorbing cotton containing graphene

Abstract

The invention relates to sound absorbing cotton, in particular to nonwoven cloth sound absorbing cotton containing graphene. The nonwoven cloth sound absorbing cotton is composed of a top face layer, a back layer and a fiber cotton layer clamped between the top face layer and the back layer, the top face layer and the back layer are made of nonwoven cloth, and the nonwoven cloth is formed by, by weight, 100 parts of isotactic polypropylene, 5-7 parts of vinyl acetate, 2-3 parts of acrylic acid-2-hydroxy propyl ester, 1-2 parts of isocyanate, 4-5 parts of silica, 2-3 parts of sodium tripolyphosphate, 12-15 parts of epoxidized soybean oil, 1-2 parts of graphene, 1-2 parts of cetyl trimethyl ammonium bromide, 3-4 parts of radix isatidis, 1-2 parts of dyer woad leaf, 2-3 parts of houttuynia cordata and 4-5 parts of auxiliary through a melt-blowing method. The nonwoven cloth which is excellent in mechanical performance and dense in cloth quality is taken as an outer layer material, so that leakage of interlayer fiber cotton is effectively prevented, effect of environment friendliness and safety, heat resistance and flame retardancy, sound absorbing and denoising and the like is realized, and the nonwoven cloth sound absorbing cotton is wide in application prospect.

Description

technical field [0001] The invention relates to a sound-absorbing cotton, in particular to a non-woven sound-absorbing cotton containing graphene. 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 ideal alternative material, which has the ...

[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
