Abstract
The utility model provides a novel sandstone environment-friendly acoustic board and belongs to sound absorption materials for architectural ornament and decoration, natural round sand grains or natural color round sand grains are mixed with epoxy resin adhesive and the pressed to a plate to form a base layer, swelling pearl stone grains and epoxy resin adhesive are mixed and then pressed on the plate to form a light layer, mesh fabric is pressed on the light layer so as to take the effects of both an intensity pulling force and a framework, after water molecule evaporation and epoxy resin adhesive solidification, a natural pore is caused, a sound-absorbing effect is taken, the specific flow resistance value is 400 Pas/m to 1200 Pas/m, finally, sand grain coating or a spray thin felt or a flame-retardant ventilating wall paper is used for treating a surface, the surface is communicated with the interior and provided with different pores so as to achieve the effect of effective sound absorption, the number of the pores can be determined according to sand grain size, different grain diameters are required for different places, and prominent absorption in high, intermediate and low frequencies can be ensured.
Description
Technical field:
The utility model 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 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.
The utility model content:
The purpose of this utility model is to provide a kind of novel sandstone environmental protection acoustical board.
This sandstone environmental protection acoustical board is combined by 4 parts, and natural round sand grains or natural colorful circle sand grains and epoxide-resin glue mixing formation base layer are provided with the light material layer on basal layer, and the light material layer is provided with the grid layer of cloth, and 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, than flow resistance value, is 300Pas/m-1000Pas/m; The spraying mat is to spray coating by glass fibre mat, than flow resistance value, is 100Pas/m-600Pas/m; 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 on sheet material; after the adhesive curing of hydrone evaporation epoxy resin, the nature hole appears; it is 400Pas/m-1200Pas/m than flow resistance value; finally, 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.
Surface layer is processed and is adopted distinct methods can reach different decorative effects, is to follow according to user's request to determine, and can freely convert.
In plate construction, the size of sandstone environmental protection acoustical board sand grains determines that hole is how many, in different places, need adopt different particle diameters, 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, meet 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.
The accompanying drawing explanation:
Accompanying drawing is the utility model sandstone environmental protection acoustical board structural representation
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 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.
