Described auxiliary agent is made up of the raw material of following weight portion: nano-sized carbon 1-2, kaolin 8-10, nano diatomite 1-2, polytetrafluoroethylene powder 3-4, titanate coupling agent TMC-TTS 3-4, tetra isopropyl two (dioctyl phosphorous acid acyloxy) titanate esters 2-3, jade powder 1-2, Diethylene Glycol Dibenzoate 3-4, n-propyl gallate 1-2, coix seed oil 1-2, vanadium diboride 2-3; Its special Preparation Method is that kaolin is placed in calcining furnace and at 700-730 DEG C, is calcined after 3-4 hour, pulverizes, and mixes with other leftover materials, grinds 1-2 hour, to obtain final product.

Described a kind of acoustical cotton anti-static flame-retardant non-woven material, is characterized in that, nonwoven cloth material is made by following step:

(1) root of large-flowered skullcap, Radix Glycyrrhizae, tangerine peel, eclipta mixed and pulverize as 200-250 order powder, for subsequent use;

(2) walnut shell is sent in retort, at 530-620 DEG C, 3-4 hour is processed in charing, takes out, and is ground into powder;

(3) isotactic polypropylene, feed back polypropylene are heated to molten condition, add step (1), (2) material, stir;

(4) in step (3) material, add other residual components, fully stir, mix, spray silk by nozzle and make nonwoven fabric.

Beneficial effect of the present invention is, in isotactic polypropylene, add feed back polypropylene, avoid the wasting of resources, the raw material such as peach-pit shell, active carbon and Chinese herbal medicine after the charing adding, the sound-absorbing soundproof effect of having promoted nonwoven cloth material, the raw materials such as chlorinated paraffin wax, silica have given material good electrical insulating property, make its antistatic and safety fire-retardant, acoustical cotton prepared by this nonwoven cloth material group, has broad application prospects.
