Abstract
The invention relates to a non-woven fabric material, in particular to an isotactic polypropylene/EVA resin composite non-woven fabric material for sound absorption cotton. The non-woven fabric material is composed of, by weight, 100 parts of isotactic polypropylene, 2 parts to 3 parts of melamine, 10 parts to 12 parts of methyl methacrylate, 2 parts to 3 parts of nano-scale titanium dioxide, 12 parts of 15 parts of polybutyl acrylate, 5 parts to 7 parts of polyethylene glycol fatty acid esters, 12 parts to 15 parts of EVA resin, 2 parts to 3 parts of white carbon black, 1 part to 2 parts of accelerants TMTD, 12 parts to 15 parts of bamboo charcoal powder, 1 part to 2 parts of lithium carbonate, 2 parts to 3 parts of lotus leaves, 1 part to 2 parts of cape jasmine, 2 parts to 3 parts of pumpkin vines and 4 parts to 5 parts of auxiliaries. According to the non-woven fabric material, the performance of the isotactic polypropylene and the performance of the EVA resin are combined, then, raw materials such as the nano-scale titanium dioxide, and the bamboo charcoal powder and the Chinese herbal medicine plant fibers are combined; the prepared non-woven fabric material resists fire and flame, absorbs sound, reduce noise, resists aging and ozone and is smooth in handfeel; after multiple layers of the non-woven fabric materials are overlapped, the sound absorption cotton can be manufactured, the process is simple, and the application potential is huge.
Description
Technical field
The present invention relates to a kind of acoustical cotton, be specifically related to a kind of isotactic polypropylene/EVA resin compound nonwoven cloth material for 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, using nonwoven fabric, as sound-absorbing material, has using value, 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, but 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 a kind of isotactic polypropylene/EVA resin compound nonwoven cloth material for acoustical cotton, reach environment friendly acoustical absorption, the object such as durable in use, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of isotactic polypropylene/EVA resin compound nonwoven cloth material for acoustical cotton, it is characterized in that, this material is made by the raw material of following weight portion: isotactic polypropylene 100, melamine 2-3, methyl methacrylate 10-12, Nano titanium dioxide 2-3, butyl polyacrylate 12-15, cithrol 5-7, EVA resin 12-15, white carbon 2-3, Vulcanization accelerator TMTD 1-2, bamboo charcoal powder 12-15, lithium carbonate 1-2, lotus leaf 2-3, cape jasmine 1-2, cushaw stem 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.
Described a kind of isotactic polypropylene/EVA resin compound nonwoven cloth material for acoustical cotton, is characterized in that, nonwoven cloth material is made by following step:
(1) lotus leaf, cape jasmine, cushaw stem mixed 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, nonwoven cloth material of the present invention combines the performance of isotactic polypropylene and EVA resin, the fibrous material flexible robust of preparation, compression resistant impacts, and glossiness is high, anti-aging, resistance to ozone, long service life, then the raw material such as combining nano grade titanium dioxide, bamboo charcoal powder, Chinese herbal medicine fiber, make this nonwoven cloth material have fire resistant flame retardant, absorbing sound and lowering noise, the resistance to ozone of anti-aging, the advantage such as be smooth to the touch.
