Description

The sandstone structure environmental protection acoustic wall of plastering
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, 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, finishing lingering fear is hit, the surface layer whole structure is not good bad phenomenon such as seam, secondary pollution, is difficult to adapt to the demand of modern architecture development.
The 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 the sound absorption reduction effect.
Summary of the invention:
Goal of the invention provides a kind of multi-functional sandstone structure environmental protection acoustic wall of plastering, can replace the common wall in the building decoration and fitment, play simultaneously sound absorption and fall behaviour's effect, this sandstone structure environmental protection acoustic wall of plastering constitutes by 7 layers and is fixed on the former metope, rough ground or lightgage steel joist formation base layer, be provided with ventilative flaggy at basal layer, ventilative flaggy is provided with epoxy glue layer, epoxy glue layer is provided with cotton flaggy, cotton flaggy is provided with the grid layer of cloth, the grid layer of cloth is provided with sandstone environmental protection acoustical board, and sandstone environmental protection acoustical board is provided with porous nano polymerization sand grains dope layer, and 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 orders and the water-soluble modified epoxy glue of bi-component, and it is 400Pas/m-1200Pas/m than flow resistance value.
The 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 value.
Block of glass wool is that 500Pas/m-1200Pas/m is than the block of glass wool of flow resistance value.
Fiber cotton plate is that 500Pas/m-1200Pas/m is than the fiber cotton plate of flow resistance value.
Basal layer: cavity size after its keel determine, cavity strengthens the thickness that has equaled to increase absorbing material, can free conversion 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 purposes and the water-soluble modified epoxy glue of bi-component, it is 400Pas/m-1200Pas/m than flow resistance value, the 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 when sound enters into this layer to variation, fully absorbed.
Epoxy glue layer: epoxide-resin glue is that environmental protection can also bondingly firmly add the fixing cotton flaggy of rifle nail and ventilative flaggy, and it mainly is 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 value and the domestic cotton plate of foam, block of glass wool and fiber cotton plate be 500Pas/m-1200Pas/m than flow resistance value, unit weight is 60kg/m 3-100kg/m 3Its layer is soft porous absorption material, mainly is the sound absorption transformation.
The grid layer of cloth: being that 5 * 5MM space glass fiber makes, mainly is 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 the grid cloth after justifying sand grains and the water-soluble modified epoxy glue of bi-component mixes by the natural sand grains of 20 order to 100 purposes or natural colorful; whole metope is without any seam; after hydrone volatilization glue condensation cure; form sandstone environmental protection suction disc metope; the hole that nature occurs from inside to outside; reach acoustically effective
Porous nano polymerization sand grains dope layer: the particulate coating material that is polymerized by nano level stone flour, granular size is 60 orders-120 orders, there is a large amount of holes particulate coating material inside, process surface layer when 2mm thickness than flow resistance at 300Pas/m-1000Pas/m, good sound absorption is arranged, and the fine and smooth whiteness of coating plays decorative effect.
In the above structure, how many sand grains sizes of sandstone environmental protection acoustical board and porous nano polymerization sand coating determines hole, 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, satisfy 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 the A2 level, be not afraid of humidity, be not afraid of hit, pernicious gas zero-emission, non-secondary pollution, without the characteristics such as seam, surface layer effect be good.
