Description

A kind of high-strength insulation acoustical absorption wall material and preparation method thereof
Technical field
The present invention relates to building material field, and in particular to a kind of high-strength insulation acoustical absorption wall material and its preparation side Method.
Background technology
With the fast development of industry, economic development is also quite rapid, and the whole world is also increasing to the demand of the energy, In the total energy consumption increasingly increased, building energy consumption is especially big, accounts for the 11 ~ 25% of total energy consumption, substantial amounts of data and experiment It is exactly to use heat insulating energy saving material all to show most fast most efficient method.Meanwhile with communications and transportation, the development of urban architecture, And the increase of the density of population, home amenity（Sound equipment, air-conditioning, television set etc.）Increase, ambient noise getting worse, it and Become a big public hazards of pollution human society environment.Common people can have an opportunity to be exposed in daily life different journeys in two In the noise of degree, it may occur however that various different degrees of hearing disabilities, noise can also influence cardiovascular health, the product of sleep Matter, or even the development of fetus.
Therefore the materials for wall of single performance cannot meet the needs of growing.Sound-absorbing material due to hole compared with More, short texture is larger to intensity effect.Therefore, the heat-insulating and sound-absorbing materials for wall for being badly in need of a kind of high intensity meets people to wall The insulation of body material, the requirement that sound-absorbing effect is good and intensity is high.
The content of the invention
For the prior art, the purpose of the invention is to provide a kind of high-strength insulation acoustical absorption wall material, the wall Strength of materials height, insulation, sound-absorbing effect are good, and employ discarded packaging foam as filler, have saved resource, have reduced material Expect cost, there is higher practical value and good application prospect.
Present invention also offers a kind of preparation method of high-strength insulation acoustical absorption wall material, available for multi-layer walls material Preparation, the preparation method is simple and practicable, and conjugation is high between every layer, and antidetonation antioxygenic property is good.
The present invention provides a kind of high-strength insulation acoustical absorption wall material, including closely bonds five-layer structure together, the One layer, layer 5 be cement top layer, the second layer and the 4th layer are sound-insulating layer, and layer 5 is sound absorbing layer.
First layer, the cement top layer of layer 5 are by portland cement, fibre reinforced materials, flyash, diatomite, antioxygen Agent, stabilizer, crushed crude pearlite are prepared, its intensity is high, by sound-absorbing, insulation, fire-retardant effect.
The second layer and the 4th layer of sound-insulating layer are by adhesive, hollow glass micropearl, silicone powder, wetting agent, magnesia It is prepared, there is sound insulation, the performance of insulation.
The attractable layer of third layer is prepared by semi-hydrated gypsum, foaming agent, activated carbon, adhesive, discarded packaging foam, is had There is the performance of acoustical absorption heat preserving.
The preparation method of the high-strength insulation acoustical absorption wall material, comprises the following steps：
Step（1）Fibre reinforced materials, flyash, diatomite, crushed crude pearlite are stirred evenly, then add portland cement, After antioxidant, stabilizer add water to stir evenly, cement skin-material is obtained, injects mould, shaping, forms first layer；
Step（2）Hollow glass micropearl, silicone powder, magnesia are stirring evenly and then adding into wetting agent and water, after stirring evenly, added Enter adhesive to continue to stir, be uniformly mixed it, obtain sound-insulating layer material, pour into step（1）The middle first layer of being molded Mould, makes it uniformly spread on the first layer, and shaping, obtains the second layer；
Step（3）After semi-hydrated gypsum, foaming agent in water stirring bubble, activated carbon, adhesive, discarded packaging foam are added Continue stirring to being uniformly mixed, pour into step（2）The middle mould for being molded the second layer, make its uniformly spread on the second layer, into Type, obtains third layer；
Step（4）4th layer of sound-insulating layer material preparation method and step（2）It is identical, after preparation, pour into step（3）It is middle into The type mould of third layer, makes it uniformly be layered in third layer, is molded, obtains the 4th layer；
Step（5）The cement skin-material preparation method and step of layer 5（1）It is identical, after preparation, pour into step（4）Middle shaping 4th layer of mould, makes it uniformly be layered on the 4th layer, is molded, and obtains layer 5, conserves drying, obtains offer of the present invention High-strength insulation acoustical absorption wall material.
In preparation process, start to prepare next layer when be not completely dried after last layer shaping, make its adjacent two Component portion phase counterdiffusion between layer, makes its combination more firm.Simultaneously as the adhesive property of adhesive and cement, makes Adjacent layer bonds together, it is not necessary to adds bonding agent again between adjacent layers, reduces the use of bonding agent, while also reduces After long-time use the problem of materials for wall layering rake angle.
Substantial amounts of foam is usually used during product packaging.After packing foam use, usually directly abandon, seldom recycling Utilize, and foam degraded is not easy, and fire hazardous, certain difficulty is brought to garbage disposal.But foam quality is light, porosity Height, is a kind of attraction packing material well.
Hollow glass micropearl is with lightweight is big, thermal conductivity factor is low, compression strength is high, dispersiveness, mobility, stabilization The advantages of property is good.In addition, also have insulation, self-lubricating, sound insulation, do not absorb water, fire resisting, corrosion-resistant, radiation protection, the superiority such as nontoxic Can, it is the splendid filler as various insulations, acoustical insulation products.
The fibre reinforced materials includes glass fibre, steel fibre and carbon fiber, and the fibre reinforced materials further includes fiber crops Sai Er fibers or wood fibre.The glass fibre includes thin glass fiber and raw glass fiber, its weight ratio is 4 ~ 6:6 ~4。
A diameter of 40-60mm of the thin glass fiber, length preferably 60 ~ 80mm of raw glass fiber, in materials for wall Middle formation glass layer, has good enhancing materials for wall intensity and sound-absorbing effect.
The silicone powder can improve the fire-retardant impact strength of materials for wall, improve the fire resistance of materials for wall, at the same time Dispersant is also used as, auxiliary agent, steel fibre, wood fibre, glass fibre, carbon fiber is preferably dispersed in filler.
The auxiliary agent includes foaming agent, stabilizer, wetting agent, antioxidant, its mass ratio is 0.5:3:1.5：1.
The high-strength insulation acoustical absorption wall material uses following parts by weight formula：15 ~ 20 parts of fibre reinforced materials, pearl 10 ~ 20 parts of rock powder, 10 ~ 20 parts of hollow glass micropearl, discarded 5 ~ 8 parts of foam of packaging, 15 ~ 20 parts of flyash, portland cement 15 ~ 20 parts, 20 ~ 25 parts of adhesive, 25 ~ 30 parts of semi-hydrated gypsum, 4.8 ~ 6.4 parts of auxiliary agent, 2 ~ 6 parts of silicone powder, 4-5 parts of magnesium chloride, activity 4-5 parts of charcoal, 8-9 parts of diatomite.
