Problems solved by technology

[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

Abstract

The invention relates to a nonwoven material, in particular to a palygorskite-containing nonwoven material for sound absorbing cotton. The nonwoven material is made from, by weight, 100 parts of isotatic polypropylene, 1-2 parts of nano-graphite powder, 2-3 parts of corundum, 1-2 parts of molybdenum disulfide, 10-12 parts of dimethyl isophthalate, 1-2 parts of methylhydroquinone, 10-12 parts of palygorskite, 8-19 parts of bentonite, 2-3 parts of forsythia, 1-2 parts of sophora flavescens, 2-3 parts of cortex lycii and 4-5 parts of auxiliaries. The nonwoven material contains the palygorskite good in sound absorption effect and is added with the corundum, the bentonite, the nano-graphite powder, Chinese medicinal herbs and the like, so that the prepared nonwoven material is flat in structure, good in breathability, firm in bonding, flame retardant and heat resistant and good in sound absorption effect; after being subjected to multi-layer superposition, the nonwoven material can be made into the sound absorbing cotton, thereby having broad application prospect.
