Description
Technical field
The preparation method who the invention provides a kind of composite sound-absorbing material, belongs to building material technical field.
Background technology
Along with the development of the modern industry, environmental pollution is also along with generation, and noise pollution is exactly the one of environmental pollution, has become the mankind's one harm greatly.Noise pollution and water pollute, topsoil is regarded as three main Environmental Problems in world wide.Common people can have an opportunity to be exposed in various noises in various degree in daily life, and noise not only can affect hearing, also can affect cardiovascular health, the quality of sleep, even growth of fetus etc.
Sound wave is in communication process, if run into barrier, a part can be reflected, and another part can be absorbed, and improves the specific absorption of material of construction to sound wave, is favourable for reducing sound pollution.Common sound absorption building materials include: sawdust-board, concrete slab, pearlite slab etc., but this class sound absorption building board has various deficiencies: for example, sound absorbing coefficient is low, poor corrosion resistance, cost are high.
Summary of the invention
For the above commentary to prior art, technical problem to be solved by this invention is: the acoustically effective of common sound-absorbing material is bad.Adopt following technical scheme:
A kind of preparation method of composite sound-absorbing material, to make by the raw material of following weight part: 10～20 parts of rubber grains, 2～3 parts of Valelinum Liquidums, 3～5 parts of water-ground limestones, 1～2 part of dicumyl peroxide, 3～5 parts of talcum powder, 3～5 parts of stearic acid, 1 part of silane coupling agent, 1 part of trimeric cyanamide, 2～3 parts of tetramethylolmethanes, 15～30 parts, vegetable fibre, 5～8 parts of clays, 5～8 parts of wilkinites, 2～4 parts, magnesium oxide, 2～4 parts of polyimide fibers, 1 part, carbon fiber, 3～6 parts of perlites, 3～5 parts of urethane foams, 2～3 parts of silicon sol, 5～10 parts of Mierocrystalline celluloses, 10～20 parts of silicate cements, 10～20 parts, water.
Preparation method comprises the steps:
S1: get rubber grain, Valelinum Liquidum, water-ground limestone, dicumyl peroxide, talcum powder, stearic acid, silane coupling agent, trimeric cyanamide, tetramethylolmethane, mix at the temperature of 90～100 DEG C;
S2: by step S1 gained mixture, send in forcing machine, extrude at 120～130 DEG C of temperature; Granulation;
S3: by S2 gained particle and vegetable fibre, clay, wilkinite, magnesium oxide, polyimide fiber, carbon fiber, perlite, urethane foam, silicon sol, Mierocrystalline cellulose, mix;
S4: add cement and water in S3 gained mixture, stir, pour in mould, curing molding, obtains finished product.
The material of described rubber grain is preferably the one in terpolymer EP rubber, styrene-butadiene rubber(SBR).
Described vegetable fibre is preferably straw or stalk.
Described Mierocrystalline cellulose is preferably the one in methylcellulose gum, Natvosol, hydroxypropylcellulose.
In described S4, the size of granulation is preferably 1～2mm.
In composite sound-absorbing material provided by the invention, adopt vegetable fibre, its voidage is good, contribute to absorb sound wave, urethane foam has certain sound insulation property, and make further sound-absorbing material keep having netted interconnective space structure by polyimide fiber and Mierocrystalline cellulose, make rubber grain, talcum powder, etc. can embed preferably wherein, the performance of strengthening sound absorption.So the sound absorption of composite sound-absorbing material provided by the invention, defening effect are good.
