Wear-resistant heat-insulating nonwoven material for sound absorbing cotton

Abstract

The invention relates to a nonwoven material, in particular to a wear-resistant heat-insulating nonwoven material for sound absorbing cotton. The nonwoven material is made from, by weight, 100 parts of isotatic polypropylene, 2-3 parts of nano-silica, 1-2 parts of hollow glass microspheres, 1-2 parts of rutile titanium dioxide, 7-9 parts of smoke sheet rubber, 12-15 parts of dimethyl fumarate, 2-3 parts of calcium stearate, 6-9 parts of zeolite, 3-4 parts of diatomite, 8-10 parts of activated carbon, 2-3 parts of humifuse euphorbia herb, 1-2 parts of scutellaria baicalensis, 1-2 parts of pueraria and 4-5 parts of auxiliaries. The nano-silica, the hollow glass microspheres and the like are contained in the nonwoven material, so that mechanical properties of the material are enhanced, and the nonwoven material is flexible, wear resistant, resistant to stretching and impact, heat-insulating and breathable; sound absorption and noise reduction effect of the material is improved by the aid of the zeolite, the diatomite, the activated carbon, Chinese medicinal herb fibers and the like; after being subjected to multi-layer superposition, the nonwoven material can be made into the sound absorbing cotton, and the nonwoven material is simple in process and broad in application prospect.

Description

technical field [0001] The invention relates to a sound-absorbing cotton, in particular to a wear-resistant and heat-insulating non-woven fabric material for the sound-absorbing cotton. Background technique [0002] Non-woven fabric is a new generation of environmentally friendly materials. It has the characteristics of moisture-proof and breathable, light and flexible, non-combustible, non-toxic and harmless, and the manufacturing process is relatively simple. It has application value. It can improve the problems of traditional sound-absorbing materials such as poor environmental protection, carcinogenicity, flammability, poor water absorption, and short service life. Both at home and abroad have begun to vigorously develop non-woven sound-absorbing materials. However, the existing non-woven sound-absorbing materials There is a single component, and only chemical fiber materials or natural fiber materials are used, so that the use environment is limited. Therefore, it is ne...

[0002] Non-woven fabric is a new generation of environmentally friendly materials. It has the characteristics of moisture-proof and breathable, light and flexible, non-combustible, non-toxic and harmless, and the manufacturing process is relatively simple. It has application value. It can improve the problems of traditional sound-absorbing materials such as poor environmental protection, carcinogenicity, flammability, poor water absorption, and short service life. Both at home and abroad have begun to vigorously develop non-woven sound-absorbing materials. However, the existing non-woven sound-absorbing materials There is a single component, and only chemical fiber materials or natural fiber materials are used, so that the use environment is limited. Therefore, it is necessary to improve the original non-woven fabric formula, and prepare sound-absorbing non-woven fabrics with excellent comprehensive performance by doping with various fibers. cloth to fully meet the daily needs of consumers
