Abstract
本发明是一种新型砂岩环保吸声板，属建筑装饰装修吸声材料，由天然圆砂粒或天然彩色圆砂粒与环氧树脂胶混合后压成板材构成基础层，膨化珍珠岩颗粒与环氧树脂胶混合后压在板材上构成轻质层，网格布压在轻质层上起到强度拉力和骨架作用，当水分子蒸发环氧树脂胶固化后出现自然孔隙，起到吸声作用，其比流阻值为400Pa·s/m-1200Pa·s/m，最后用砂粒涂料或喷涂薄毡或阻燃透气壁纸处理面层，面层与内部连通都有不同的孔隙达到有效的吸声作用，砂粒大小决定孔隙多少，不同的场所需求采用不同的粒径，确保高中低频率有突出性吸收。
The invention is a new type of sandstone environmental protection sound-absorbing board, which belongs to the sound-absorbing material for building decoration. The resin glue is mixed and pressed on the board to form a light layer. The mesh cloth is pressed on the light layer to play the role of strength tension and skeleton. When the water molecules evaporate and the epoxy resin glue is cured, natural pores appear, which play a role in sound absorption. Its specific flow resistance value is 400Pa·s/m-1200Pa·s/m. Finally, the surface layer is treated with sand paint or sprayed with thin felt or flame-retardant and breathable wallpaper. The surface layer and the interior have different pores to achieve effective sound absorption. Function, the size of the sand particles determines the number of pores, and different places require different particle sizes to ensure outstanding absorption of high, medium and low frequencies.
Description
Technical field:
The present invention is multi-functional sandstone environmental protection acoustical board, belongs to the sound absorption material field of building decoration and fitment, acoustics design, noise reduction.
Background technology:
Sound absorption material is the functional material of building decoration and fitment, absorption of noise by material, reasonably tonequality designs to people living environment and a place that peace and quiet are comfortable is provided, existing architectural decoration sound absorption material on the market at home, kind much all cuts both ways, fire-protection rating is poor, absorption band is not wide, the finishing lingering fear is hit, the bad phenomenon such as the surface layer whole structure is not good, secondary pollution, is difficult to adapt to the demand of modern architecture development.
Summary of the invention:
The purpose of this invention is to provide a kind of novel sandstone environmental protection acoustical board.
This sandstone environmental protection acoustical board is combined by 4 parts; natural round sand grains or natural colorful circle sand grains and epoxide-resin glue mixing formation base layer; basal layer be provided with the light material layer, the light material layer is provided with the grid layer of cloth, the grid layer of cloth is provided with architectural surface.
Natural round sand grains or natural colorful circle sand grains and epoxide-resin glue mixing formation base layer, sand grains is 20 order to 100 orders, epoxide-resin glue is two water-soluble modified epoxy glue of component; The light material layer is that the fine perlite particle mixes with epoxide-resin glue, and unit weight is 200-300kg/m
3The grid layer of cloth is that 5 * 5MM space glass fiber makes; Architectural surface is to be made by sand grains coating or spraying mat or fire-retardant ventilative wallpaper; The sand grains size of sand grains coating is 60 orders-120 orders, is 300Pas/m-1000Pas/m than flow resistance value; The spraying mat is to spray coating by glass fibre mat, is 100Pas/m-600Pas/m than flow resistance value; On the surface layer of fire-retardant ventilative wallpaper micropore being arranged, is 200Pas/m-800Pas/m than flow resistance value.
Natural round sand grains or natural colorful circle sand grains are pressed into sheet material after mixing with the water-soluble modified epoxy glue of two components; compress light material fine perlite particle, grid cloth at sheet material; the nature hole appears after the adhesive curing of hydrone evaporation epoxy resin; it is 400Pas/m-1200Pas/m than flow resistance value; with sand grains coating or spraying mat or fire-retardant ventilative wallpaper treated side layer, surface layer and internal communication have hole to reach sound absorption at last.
Surface layer is processed and is adopted distinct methods can reach different decorative effects, is to follow according to user's request to decide, can free conversion.
In the plate construction, how many sizes of sandstone environmental protection acoustical board sand grains determines hole, need adopt different particle diameters in different places, guarantees that high, normal, basic frequency has high-lighting to absorb.
Sandstone environmental protection acoustical board is the domestic and international sound absorbent for building market diversification of horn of plenty, improve sound absorbent for building quality, occupation rate of market and utilization rate, satisfy the novel regeneration product of the demand of people's Modern Live level, sound absorption coefficient between 0.4-0.9, high, normal, basic frequency absorption can arbitrarily adjust, prevent fires reach the A2 level, be not afraid of humidity, be not afraid of hit, the characteristics such as pernicious gas zero-emission, non-secondary pollution, surface layer effect are good.
Description of drawings:
Accompanying drawing is sandstone environmental protection acoustical board structural representation of the present invention
In the drawings: 1 natural round sand grains or natural colorful circle sand grains and epoxide-resin glue, 2 fine perlite particle and epoxide-resin glues, 3 grid cloths, 4 surface layers.
The specific embodiment:
Sandstone environmental protection acoustical board is to be mixed with epoxide-resin glue by natural round sand grains or natural colorful circle sand grains, and the fine perlite particle mixes with glue, grid cloth, and surface layer 4 parts of sand grains coating or spraying mat or fire-retardant ventilative wallpaper combine.The first step: select the natural round sand grains of equal particle diameter or natural colorful circle sand grains to mix with epoxide-resin glue, be pressed into sheet material, second step: get equal particle diameter fine perlite particle and mix with epoxide-resin glue and be pressed on the first step plate material, the 3rd step: 5 * 5MM space glass fiber grid cloth is pressed on the fine perlite particle board; The 4th step: after hydrone evaporation with sand grains coating or spray mat or fire-retardant ventilative wallpaper is handled the surface layer effect well.
