Diatomite-containing nonwoven material for sound absorbing cotton

Abstract

The invention relates to a nonwoven material, in particular to a diatomite-containing nonwoven material for sound absorbing cotton. The nonwoven material is made from, by weight, 100 parts of isotactic polypropylene, 12-15 parts of diatomite powder, 5-8 parts of texanol, 12-15 parts of dimethyl isophthalate, 7-9 parts of chlorcosane, 3-4 parts of dioctyl maleate, 1-2 parts of quartz powder, 10-12 parts of rice hulls, 5-7 parts of bamboo charcoal powder, 2-3 parts of dandelion, 1-2 parts of agrimonia pilosa, 1-2 parts of rheum officinale, 2-3 parts of seeds of Job's tears, 1-2 parts of honeysuckle stems and 4-5 parts of auxiliaries. The nonwoven material contains the diatomite powder, the quartz powder and the like, thereby being improved in mechanical properties and durable in use; due to the raw materials such as the rice hulls, the bamboo charcoal powder and Chinese medicinal herbs, the material is low in cost and has good sound absorption effect; flame retardation and water resistance of the material are improved due to the chlorcosane; 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 non-woven fabric material containing diatomite 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 necessary to imp...

[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
