Inexpensive nonwoven fabric sound absorption cotton containing rice hulls

Abstract

The invention relates to sound absorption cotton, in particular to a piece of inexpensive nonwoven fabric sound absorption cotton containing rice hulls. The inexpensive nonwoven fabric sound absorption cotton containing the rice hulls is composed of a top surface layer, a back surface layer and a fiber cotton layer clamped between the top surface layer and the back surface layer, wherein the top surface layer and the back surface layer are made of nonwoven fabric material, and the nonwoven fabric material is prepared by performing a melt blowing method on raw materials of, based on the following weight part ratio, 100 parts of isotatic polypropylene, 1-2 parts of zinc chloride, 2-3 parts of silica sol, 1-2 parts of white emulsion, 10-12 parts of dioctyl phthalate, 3-4 parts of chlorinated polyethylene, 1-2 parts of sodium abietate, 10-12 parts of the rice hulls, 2-3 parts of creeping oxalis, 1-2 parts of dayflower, 2-3 parts of garden balsam stems, 1-2 parts of red peony roots and 4-5 parts of accessory ingredients. The inexpensive nonwoven fabric sound absorption cotton uses the nonwoven fabric as outer layer material, has the advantages of protecting environment and being safe, preventing dust and water, resisting heat and retarding flame, absorbing sound and reducing noise and the like, is suitable for sound insulation in various environmental conditions, and low in production cost, and has popularization and application value.

Description

technical field [0001] The invention relates to a sound-absorbing cotton, in particular to a low-cost non-woven sound-absorbing cotton containing rice husks. 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, whi...

[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
