Technical field:
The present invention is the multi-functional sandstone structure environmental protection acoustic wall of plastering, and belongs to building decoration and fitment, the sound absorption material field in building acoustics design and sound absorption reduction place.
Background technology:
Sound absorption material is the functional material of building decoration and fitment, by the absorption of noise of 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, finishing lingering fear is hit, surface layer whole structure is not good a bad phenomenon such as seam, secondary pollution, is difficult to adapt to the demand of modern architecture development.
Ordinary Portland cement brick wall only has the absorption of 0.1-0.15, and sound absorption is very little, and the sandstone structure environmental protection acoustic wall of plastering is Multifunction wall, and it can play sound absorption reduction effect.
Summary of the invention:
Goal of the invention is to provide a kind of multi-functional sandstone structure environmental protection acoustic wall of plastering, can replace the common wall in building decoration and fitment, play sound absorption simultaneously and fall behaviour's effect, this sandstone structure environmental protection acoustic wall of plastering constitutes and is fixed on former metope by 7 layers, rough ground or lightgage steel joist formation base layer, on basal layer, be provided with ventilative flaggy, ventilative flaggy is provided with epoxy glue layer, epoxy glue layer is provided with cotton flaggy, cotton flaggy is provided with grid layer of cloth, grid layer of cloth is provided with sandstone environmental protection acoustical board, sandstone environmental protection acoustical board is provided with porous nano polymerization sand grains dope layer, each layer has different effects.
Ventilative flaggy is sandstone environmental protection acoustical board or hard material perforated plate or foamed aluminium board.
Sandstone environmental protection acoustical board is mixed by the natural sand grains of 20 order to 100 order and the water-soluble modified epoxy glue of bi-component, and it is 400Pas/m-1200Pas/m than flow resistance.
Hard material perforated plate is the hard material perforated plate of 25%-50% perforated percentage.
Foamed aluminium board is the foamed aluminium board of 50%-90% porosity.
Cotton flaggy is the cotton plate of ventilation foam or block of glass wool or fiber cotton plate.
The cotton plate of ventilation foam is that 300Pas/m-800Pas/m is than the cotton plate of the foam of flow resistance.
Block of glass wool is that 500Pas/m-1200Pas/m is than the block of glass wool of flow resistance.
Fiber cotton plate is that 500Pas/m-1200Pas/m is than the fiber cotton plate of flow resistance.
Basal layer: cavity size after its keel determine, cavity strengthens the thickness that has equaled to increase absorbing material, can freely convert according to design sound absorption frequency needs.
Ventilative flaggy: its sandstone environmental protection acoustical board or hard material perforated plate or foamed aluminium board, sandstone environmental protection acoustical board is mixed by the natural sand grains of 20 order to 100 object and the water-soluble modified epoxy glue of bi-component, it is 400Pas/m-1200Pas/m than flow resistance, hard material perforated plate is the hard material perforated plate of 25%-50% perforated percentage, and foamed aluminium board is the foamed aluminium board of 50%-90% porosity.Main Function is for supporting fixing cotton flaggy, can generation sound in the time that sound enters into this layer to variation, fully absorbed.
Epoxy glue layer: epoxide-resin glue both environmental protection can also be bonding firm, the fixing cotton flaggy of additional rifle nail and ventilative flaggy, it is mainly bonding cotton flaggy and air-permeable layer.
Cotton flaggy: be the cotton plate of foam or block of glass wool or fiber cotton plate, the cotton plate of foam is that 300Pas/m-800Pas/m is than the cotton plate of the German BASF foam of flow resistance and the domestic cotton plate of foam, block of glass wool and fiber cotton plate be 500Pas/m-1200Pas/m than flow resistance, unit weight is 60kg/m
3-100kg/m
3.
Grid layer of cloth: being that 5 × 5MM space glass fiber makes, is mainly the sandstone environmental protection acoustical board of fixedly plastering, and improves its intensity and pulling force.
Sandstone environmental protection acoustical board: be to be put on grid cloth after being mixed with the water-soluble modified epoxy glue of bi-component by the natural sand grains of 20 order to 100 object or natural colorful circle sand grains; whole metope is without any seam; when after hydrone volatilization glue condensation cure; form sandstone environmental protection suction disc metope; there is from inside to outside natural hole; reach acoustically effective
Porous nano polymerization sand grains dope layer: the particulate coating material being polymerized by nano level stone flour, granular size is 60 order-120 orders, there is a large amount of holes particulate coating material inside, process surface layer in the time of 2mm thickness than flow resistance at 300Pas/m-1000Pas/m, have good sound absorption, the fine and smooth whiteness of coating plays decorative effect.
In above structure, the sand grains size of sandstone environmental protection acoustical board and porous nano polymerization sand coating determines that hole is how many, the size of cotton flaggy flow resistance value determines the acoustically effective of frequency, need adopt different design schemes in different places, guarantees that high, normal, basic frequency has high-lighting to absorb.
The sandstone structure environmental protection acoustic wall of plastering 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 people's Modern Live level requirement, sound absorption coefficient between 0.4-0.9, high, normal, basic frequency absorption can arbitrarily adjust, prevent fires reach A2 level, be not afraid of humidity, be not afraid of hit, pernicious gas zero-emission, non-secondary pollution, without the feature such as seam, surface layer effect be good.
