Isotactic polypropylene/EVA resin composite non-woven fabric material for sound absorption cotton

Abstract

The invention relates to a non-woven fabric material, in particular to an isotactic polypropylene / EVA resin composite non-woven fabric material for sound absorption cotton. The non-woven fabric material is composed of, by weight, 100 parts of isotactic polypropylene, 2 parts to 3 parts of melamine, 10 parts to 12 parts of methyl methacrylate, 2 parts to 3 parts of nano-scale titanium dioxide, 12 parts of 15 parts of polybutyl acrylate, 5 parts to 7 parts of polyethylene glycol fatty acid esters, 12 parts to 15 parts of EVA resin, 2 parts to 3 parts of white carbon black, 1 part to 2 parts of accelerants TMTD, 12 parts to 15 parts of bamboo charcoal powder, 1 part to 2 parts of lithium carbonate, 2 parts to 3 parts of lotus leaves, 1 part to 2 parts of cape jasmine, 2 parts to 3 parts of pumpkin vines and 4 parts to 5 parts of auxiliaries. According to the non-woven fabric material, the performance of the isotactic polypropylene and the performance of the EVA resin are combined, then, raw materials such as the nano-scale titanium dioxide, and the bamboo charcoal powder and the Chinese herbal medicine plant fibers are combined; the prepared non-woven fabric material resists fire and flame, absorbs sound, reduce noise, resists aging and ozone and is smooth in handfeel; after multiple layers of the non-woven fabric materials are overlapped, the sound absorption cotton can be manufactured, the process is simple, and the application potential is huge.

Description

technical field [0001] The invention relates to a sound-absorbing cotton, in particular to an isotactic polypropylene / EVA resin composite 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...

[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
