Abstract
The invention relates to sound absorbing cotton, in particular to nonwoven cloth sound absorbing cotton containing graphene. The nonwoven cloth sound absorbing cotton is composed of a top face layer, a back layer and a fiber cotton layer clamped between the top face layer and the back layer, the top face layer and the back layer are made of nonwoven cloth, and the nonwoven cloth is formed by, by weight, 100 parts of isotactic polypropylene, 5-7 parts of vinyl acetate, 2-3 parts of acrylic acid-2-hydroxy propyl ester, 1-2 parts of isocyanate, 4-5 parts of silica, 2-3 parts of sodium tripolyphosphate, 12-15 parts of epoxidized soybean oil, 1-2 parts of graphene, 1-2 parts of cetyl trimethyl ammonium bromide, 3-4 parts of radix isatidis, 1-2 parts of dyer woad leaf, 2-3 parts of houttuynia cordata and 4-5 parts of auxiliary through a melt-blowing method. The nonwoven cloth which is excellent in mechanical performance and dense in cloth quality is taken as an outer layer material, so that leakage of interlayer fiber cotton is effectively prevented, effect of environment friendliness and safety, heat resistance and flame retardancy, sound absorbing and denoising and the like is realized, and the nonwoven cloth sound absorbing cotton is wide in application prospect.
Description
Technical field
The present invention relates to a kind of acoustical cotton, be specifically related to a kind of nonwoven fabric acoustical cotton that contains Graphene.
Background technology
Acoustical cotton is the effect materials such as a class set absorbing sound and lowering noise, control tonequality and decoration, be widely used in the places such as household, music hall, cinema, automobile, factory building, traditional acoustical cotton material is mainly the materials such as glass fibre, polyester fiber, rock wool, mineral wool, yet there is certain defect in acoustical cotton prepared by these materials, as poor in the feature of environmental protection, cause a disease carcinogenic, inflammable, water imbibition is poor, service life is short etc., therefore, be necessary to improve original acoustical cotton material, to improve its Environmental Safety, improve user's experience; Nonwoven fabric is undoubtedly a kind of desirable alternative materials, it have moisture retardant, pliable and tough light weight, good permeability, can recycle, the advantage such as nontoxic, coordinate again other sound-absorbing materials, can effectively improve the defect of existing acoustical cotton, promote sound-absorbing, soundproof effect.
Summary of the invention
The object of the invention is to, for the deficiency of current material, provide a kind of nonwoven fabric acoustical cotton that contains Graphene, make it have good mechanical property, and environmental protection flame retardant, sound absorption and noise isolation, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of nonwoven fabric acoustical cotton that contains Graphene, by top coat, back layer, and the cellucotton layer being clipped between top coat and back layer forms, described top coat, back layer adopts nonwoven cloth material, nonwoven fabric described in it is characterized in that is made by meltblown by the raw material of following weight portion: isotactic polypropylene 100, vinylacetate 5-7, 2-hydroxypropyl acrylate 2-3, isocyanates 1-2, silica 4-5, sodium phosphate trimer 2-3, epoxidized soybean oil 12-15, Graphene 1-2, softex kw 1-2, Radix Isatidis 3-4, folium isatidis 1-2, cordate houttuynia 2-3, auxiliary agent 4-5,
Described auxiliary agent is made by the raw material of following weight portion:.
Described a kind of nonwoven fabric acoustical cotton that contains Graphene, is characterized in that, nonwoven cloth material is made by following step:
(1) Radix Isatidis, folium isatidis, cordate houttuynia mixed and pulverize as 200-250 order powder, then the powder air blast to gained, seethes it, and to spray form epoxidized soybean oil in the powder seething, the two is fully mixed;
(2) isotactic polypropylene is heated to molten condition, adds step (1) material, stir;
(3) in step (2) material, add other residual components, fully stir, mix, by nozzle, spray silk and make nonwoven fabric.
Beneficial effect of the present invention is, the raw materials such as the Graphene adding in isotactic polypropylene, silica have effectively improved the mechanical property of material, and its pliable and tough wear-resisting, stretch-proof is impacted; Add in addition the natural plant fibres such as Chinese herbal medicine, increased the absorbing sound and lowering noise effect of material.The nonwoven cloth material that these raw materials are made is as the exterior material of acoustical cotton, and cloth matter is closely knit, can be good at preventing interlayer cellucotton seepage, Environmental Safety, and heat-proof combustion-resistant, absorbing sound and lowering noise, reusable edible, application prospect is extensive.
