Wear-resistant and temperature-resistant non-woven fabric sound-absorbing cotton

Abstract

The invention relates to sound-absorbing cotton, in particular to wear-resistant and temperature-resistant non-woven fabric sound-absorbing cotton. The sound-absorbing cotton comprises a top layer, a back layer and a fiber cotton layer clamped between the top layer and the back layer. Each of the top layer and the back layer is made of non-woven fabric. The non-woven fabric made by a melt-blown method comprises, by weight, 100 parts of isotactic polypropylene, 4-5 parts of stearic acid, 1-2 parts of sodium carboxymethylcellulose, 1-2 parts of nickel powder, 2-3 parts of polyethylene wax, 12-15 parts of epoxy linseed oil, 1-2 parts of anti-aging agent AW, 1-2 parts of accelerator NOBS, 8-10 parts of activated carbon powder, 1-2 parts of sodium metaaluminate, 3-4 parts of salviae miltiorrhizae, 1-2 parts of spatholobus suberctu, 2-3 parts of herba leonuri and 4-5 parts of auxiliaries. The sound-absorbing cotton containing activated carbon powder, polyethylene wax, traditional Chinese medicines, and the like is environmental friendly, nonflammable, temperature change resistant, excelling in sound-absorbing effect, capable of absorbing harmful components in environments and worthy of application.

Description

technical field [0001] The invention relates to a sound-absorbing cotton, in particular to a wear-resistant and temperature-resistant 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 ideal alternative mat...

[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
