The object of the invention is to, for the deficiency of current material, provide a kind of wear-resistant temperature-resistant nonwoven fabric acoustical cotton, long service life, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of wear-resistant temperature-resistant 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, stearic acid 4-5, sodium carboxymethylcellulose 1-2, nickel powder 1-2, Tissuemat E 2-3, epoxy Linseed oil 12-15, antioxidant A W 1-2, accelerant NOBS 1-2, activated carbon powder 8-10, sodium metaaluminate 1-2, red sage root 3-4, reticulate millettia 1-2, motherwort 2-3, 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 wear-resistant temperature-resistant nonwoven fabric acoustical cotton, is characterized in that, nonwoven cloth material is made by following step:
(1) red sage root, reticulate millettia, motherwort mixed and pulverize as 200-250 order powder, then the powder air blast to gained, seethes it, and to spray form epoxy Linseed 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, in isotactic polypropylene, added the raw materials such as activated carbon powder, Tissuemat E, Chinese herbal medicine, not only improved the mechanical property of material, made its pliable and tough wear-resisting, stretch-proof impact, thermal conductivity factor is low, high temperature resistant low temperature, long service life, has also increased the absorbing sound and lowering noise effect of material, Sound-proof material prepared by this nonwoven cloth material, Environmental Safety, nonflammable, heatproof change, sound-absorbing effect is good, and itself also possesses the characteristic of absorbing environmental pernicious gas, has using value.
