Abstract
The invention relates to a nonwoven material, in particular to a palygorskite-containing nonwoven material for sound absorbing cotton. The nonwoven material is made from, by weight, 100 parts of isotatic polypropylene, 1-2 parts of nano-graphite powder, 2-3 parts of corundum, 1-2 parts of molybdenum disulfide, 10-12 parts of dimethyl isophthalate, 1-2 parts of methylhydroquinone, 10-12 parts of palygorskite, 8-19 parts of bentonite, 2-3 parts of forsythia, 1-2 parts of sophora flavescens, 2-3 parts of cortex lycii and 4-5 parts of auxiliaries. The nonwoven material contains the palygorskite good in sound absorption effect and is added with the corundum, the bentonite, the nano-graphite powder, Chinese medicinal herbs and the like, so that the prepared nonwoven material is flat in structure, good in breathability, firm in bonding, flame retardant and heat resistant and good in sound absorption effect; after being subjected to multi-layer superposition, the nonwoven material can be made into the sound absorbing cotton, thereby having broad application prospect.
Description
Technical field
The present invention relates to a kind of acoustical cotton, be specifically related to the nonwoven cloth material containing palygorskite for a kind of acoustical cotton.
Background technology
Nonwoven fabric is environment-friendly materials of new generation, have moistureproof ventilative, light weight is pliable and tough, not combustion-supporting, the characteristic such as nontoxic, and manufacturing technique is relatively simple, its range of application is more and more wider, the nonwoven fabric of usining has using value as sound-absorbing material, it is poor that it can improve traditional sound-absorbing material feature of environmental protection, cause a disease carcinogenic, inflammable, water imbibition is poor, the problems such as service life is short, all start to greatly develop nonwoven fabric sound-absorbing material at home and abroad, yet existing nonwoven fabric sound-absorbing material exists composition single, only use chemical fibre material or natural fiber material, its environment for use is restricted, therefore be necessary to improve original formula of non-woven cloth, with it, pass through multiple fiber doping, prepare the sound-absorbing nonwoven fabric of high comprehensive performance, required fully to meet consumer's daily life.
Summary of the invention
The object of the invention is to, for the deficiency of current material, provide the nonwoven cloth material containing palygorskite for a kind of acoustical cotton, to improve the sound-absorbing effect of nonwoven cloth material, to achieve these goals, the technical solution used in the present invention is as follows:
Nonwoven cloth material containing palygorskite for a kind of acoustical cotton, it is characterized in that, this material is made by the raw material of following weight portion: isotactic polypropylene 100, Nano graphite powder 1-2, corundum 2-3, molybdenum bisuphide 1-2, dimethyl isophthalate 10-12, methylnaphthohydroquinone 1-2, palygorskite 10-12, bentonite 8-19, capsule of weeping forsythia 2-3, kuh-seng 1-2, root bark of Chinese wolf-berry 2-3, auxiliary agent 4-5;
Described auxiliary agent is made by 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 ℃, is calcined after 3-4 hour, pulverizes, and mixes with other leftover materials, grinds 1-2 hour, obtains.
The described nonwoven cloth material containing palygorskite for a kind of acoustical cotton, is characterized in that, nonwoven cloth material is made by following step:
(1) capsule of weeping forsythia, kuh-seng, the root bark of Chinese wolf-berry mixed and pulverize as 200-250 order powder, standby;
(2) corundum, palygorskite, bentonite are put into calcining furnace and calcine 3-4 hour at 710-740 ℃, take out cooling after, be ground into 300-400 object powder;
(3) isotactic polypropylene is heated to molten condition, adds step (1), (2) material, stir;
(4) in step (3) material, add other residual components, fully stir, mix, by nozzle, spray silk and make nonwoven fabric.
Beneficial effect of the present invention is, the palygorskite adding in this nonwoven cloth material, short texture, has good sound absorption, the raw material such as combined corundum, bentonite, Nano graphite powder, Chinese herbal medicine fiber again, make the fibrous material preparing have good hardness and toughness, structure is smooth, ventilative good, bonding firmly, flame-proof heat-resistant, sound-absorbing effect is good, has broad application prospects.
