Description
Technical field
The present invention relates to sound-absorbing material technical field, particularly relate to a kind of high tenacity high durable acoustical cotton and preparation method thereof.
Background technology
Due to rapid development of economy, the value volume and range of product of noise source gets more and more, and noise pollution has permeated people's work, the every field of life, noise become affect people's lives the most seriously, there is one of widest pollution.With the continuous enhancing of environmental consciousness, problem of noise pollution is increasingly subject to people's attention.For seeking solution, it is ensured that people's life, being normally carried out of learning activities, need to continually develop the new material that can control noise hazard.
Acoustical cotton belongs to sound-absorbing porous material, when sound by duct when, multiple reflections in the material, sound energy attenuation and reach sound absorption function.Conventional acoustical cotton has glass fibre acoustical cotton and polyester fiber acoustical cotton, and the glass fibre acoustical cotton feature of environmental protection is poor, and raw material contains hazardous substance, and easily causes itch, and be not easy to construction when touching the skin of people.Polyester fiber acoustical cotton is harmless, but poor mechanical property, it is easy to deformation, processing difficulties, durability is not high, and weatherability is poor, it is in use easily subject to the impact of natural conditions, make product appearance variation, degradation, have a strong impact on its normal use.
Content of the invention
The object of the invention is contemplated to make up the defect of prior art, provides a kind of high tenacity high durable acoustical cotton and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of high tenacity high durable acoustical cotton, it is to be prepared by the raw material of following weight parts:
PTT 10-15, CSL 1-2, polypropylene 70-90, gelatin 0.5-1, attapulgite 5-10, lauryl sodium sulfate 0.5-1, styrene 2-4, epoxidized soybean oil 0.5-1, antioxidant BHT 0.3-0.5, light stabilizer UV-531 0.3-0.5, butyl methacrylate 3-5, dioctyl phthalate 3-5, azodiisobutyronitrile 0.05-0.1, function powder 3-5；
Wherein function powder is prepared by the raw materials in: tourmaline powder 5-10, medical stone powder 3-5, nano titanium oxide 2-4, cerium oxide 1-2, hydroxypropyl methyl cellulose 1-2, polyvinyl alcohol 1-2, water 40-60；The preparation method of function powder be first hydroxypropyl methyl cellulose and polyvinyl alcohol are added to the water 85-95 DEG C under the conditions of stirring 0.5-1h, it is subsequently adding remaining raw material and continues stirring 1-2h, be dried completely after filtration, then at 700-800 DEG C of calcining 1-2h, grind uniformly after cooling, to obtain final product.
The preparation method of a kind of high tenacity high durable acoustical cotton, comprises the following steps:
(1) it lauryl sodium sulfate is configured to the aqueous solution of 0.5-1% and jointly add in reactor with gelatin; prior to 60-80 DEG C, 400-600r/min stir 0.5-1h; it is subsequently adding attapulgite and function powder ultrasonic disperse 5-10min; temperature is adjusted to 50-60 DEG C; styrene, butyl methacrylate and azodiisobutyronitrile stirring 4-6h is added under logical nitrogen protective condition; cooled and filtered, washing, drying, be subsequently adding epoxidized soybean oil and mix, and obtains modified powder after air-flow crushing；
(2) by uniform with polypropylene, PTT, antioxidant BHT, light stabilizer UV-531, dioctyl phthalate and CSL mixed at high speed for the modified powder in (1), then extruded in 200-260 DEG C of melting mixing by double screw extruder, melt spinning method carries out spinning routinely, obtains composite fibre；
(3) composite fibre in (2) carried out shredding, combing, be stacked into net, then hot-forming, after surface treatment, i.e. obtain high tenacity high durable acoustical cotton.
The invention have the advantage that the complex function powder with efficient anion releasing effect and attapulgite are carried out by the present invention compounding as filler, and utilize styrene and the polymerization of butyl methacrylate emulsion to carry out composite modified to filling surface, effectively enhance the compatibility between filler and polypropylene matrix and synergy, both the mechanical property of synthetic material had been improved, effectively improve again the porosity of material, promote sound absorbing capabilities；Meanwhile, with remaining raw material compounding formation composite fibre base-material, then composite fibre is obtained by melt spinning method; then prepare product by common process so as to get acoustical cotton not only there is acoustically effective and the feature that mechanical property is good, durability is high, and have high tenacity and high-weatherability; steady quality; service life is long, safety and environmental protection, moreover it is possible to absorb the harmful substance in air; effectively purify air; protection health, comprehensive value is high, practical.
