Abstract
The invention relates to acoustic foam, in particular to environment-friendly flame-retardant efficient nonwoven acoustic foam comprising a top layer, a back layer, and a fiber bulk layer between the top layer and the back layer. Both the top layer and the back layer are made of nonwoven. The nonwoven is made with, by weight, 100 parts of isotactic polypropylene, 2-3 parts of decabromodiphenylethane, 3-4 parts of antimonous oxide, 1-2 parts of calcium stearate, 1-2 parts of methyl cellulose ether, 6-8 parts of cassava starch, 2-3 parts of triphenyl phosphate, 12-15 parts of epoxy fatty acid butyl ester, 3-5 parts of peony root, 1-2 parts of tea tree root, 2-3 parts of burdock, 1-2 parts of light yellow Sophora root, 2-3 parts of scandent hop, 1-2 parts of peach blossom, and 4-5 parts of aid. The environment-friendly flame-retardant efficient nonwoven acoustic foam with the outer layer of soft, solid, fireproof and flame-retardant nonwoven has the advantages of environmental friendliness, safety, capability of absorbing noise and reducing noise and the like and has promising application prospect.
Description
Technical field
The present invention relates to a kind of acoustical cotton, be specifically related to a kind of environment-friendly high-efficiency fire retardant nonwoven fabric acoustical cotton.

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 environment-friendly high-efficiency fire retardant nonwoven fabric acoustical cotton, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of environment-friendly high-efficiency fire retardant nonwoven fabric acoustical cotton, 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, TDE 2-3, antimonous oxide 3-4, calcium stearate 1-2, methyl cellulose ether 1-2, tapioca 6-8, triphenyl phosphate 2-3, epoxyoleic acid butyl ester 12-15, tree peony root 3-5, tea root 1-2, great burdock achene 2-3, kuh-seng 1-2, humulus grass 2-3, peach blossom 1-2, auxiliary agent 4-5,
Described auxiliary agent is made by the raw material of following weight portion: mica 30-40, nano-sized carbon 1-2, antioxidant MB 1-2, aluminate coupling agent DL-411 3-4, Sodium Benzoate 1-2,582-2 amino resins 3-4, actinolite 2-3, urea 1-2, cyanuric acid zinc 2-3, epoxyoleic acid butyl ester 35-40, n-propyl gallate 2-3, coix seed oil 1-2, vanadium carbide 2-3, Tea Polyphenols 1-2; Preparation method sends into mica, actinolite in calcining furnace and calcine 2-3 hour at 720-740 ℃, then, takes out, and sends in the hydrochloric acid solution of 10-15% and soaks 2-3 hour, filters, and obtains filter residue, with clear water, cleans, and dries, grinds to form 400-600 order powder; Gained powder mixes with other residual components, is heated to 60-70 ℃, and stirring reaction 40-50 minute is cooling, grinds to form slurry, obtains.
Described a kind of environment-friendly high-efficiency fire retardant nonwoven fabric acoustical cotton, is characterized in that, nonwoven cloth material is made by following step:
(1) by tree peony root, tea root, great burdock achene, kuh-seng, humulus grass, peach blossom mixes and pulverize as 200-250 order powder, standby;
(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 TDE, antimonous oxide have effectively strengthened the fire resistant flame retardant effect of traditional isotactic polypropylene nonwoven cloth material, in addition the natural plant fibres such as Chinese herbal medicine that add, have increased the absorbing sound and lowering noise effect of material, the acoustical cotton of preparing with this nonwoven cloth material, cloth matter is closely knit, good permeability, sound-absorbing soundproof effect is good, and Environmental Safety, incompressible distortion, long service life, reusable edible, application prospect is extensive.
