Wear-resistant and heat-insulated non-woven fabric material for sound absorption cotton

Abstract

The invention provides a wear-resistant and heat-insulated non-woven fabric material for sound absorption cotton. The non-woven fabric material is prepared from, by weight, 100 parts of isotatic polypropylene, 2-3 parts of nano-silicon dioxide, 1-2 parts of hollow glass microspheres, 1-2 parts of rutile-type 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 radix scutellariae, 1-2 parts of kudzuvine roots and 4-5 parts of auxiliaries. According to the wear-resistant and heat-insulated non-woven fabric material for the sound absorption cotton, due to the fact that the raw materials such as nano-silicon dioxide and the hollow glass microspheres are contained, the mechanical property of the material is enhanced, and the material achieves the flexibility, wear resistance, stretch resistance, impact resistance, heat insulation and air permeability; by adding the raw materials such as the zeolite, the diatomite, the activated carbon and Chinese herb plant fiber, the sound absorption and noise reduction effects of the material are improved. The sound absorption cotton can be made by stacking multiple layers of non-woven fabrics, the processes are simple, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of non-woven materials, in particular to a wear-resistant and heat-insulating non-woven material for 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 neces...

[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
