A kind of novel acid and alkali-resistance anti-flaming thermal-insulation material
Technical field
The utility model relates to a kind of heat-barrier material, and particularly a kind of novel acid and alkali-resistance anti-flaming thermal-insulation material belongs to the heat-barrier material technical field of architectural usefulness.
Background technology
Along with expanding economy, the whole world increases demands for energy day by day, and in the total energy consumption that constantly increases, building energy consumption accounts for 11%~25% of total energy consumption, and therefore, the building energy conservation problem has caused the attention of more and more countries.Facts have proved that building energy conservation the most directly effective method is to use heat preserving and insulating material.Heat-barrier material commonly used at present mainly contains: foam glass, polystyrene foam plastics, nano-pore heat-barrier material, glue powder polyphenyl granule insulating material, thermal insulation mortar, gas concrete, litaflex, composite silicate thermal insulation material etc.But have following shortcoming as the one of which: at first, damping performance is poor, and easy oxidation and corrosion, and application life is short, loses waterproof, heat insulation function in general two to three years gradually.Secondly, this material extending and lower to tensile strength in length and breadth, contact with foreign matter or weight under be prone to break, and surface finish is relatively poor, the sunray reflectivity is lower; Heat insulation, heat-insulating property is relatively poor relatively.Once more, no air barrier layer in the middle of this material, interior outside energy forms convection current, conduction easily, thereby influences heat insulation usefulness; At last, burning easily, poor fire.
Therefore, develop and a kind ofly not only have corrosion-resistant but also have high effect of heat insulation, the novel heat insulation material of economy and durability is the relevant industries urgent problems.
Summary of the invention
The utility model purpose is a kind of corrosion-resistant high effect of heat insulation that has that both had to be provided, the novel heat insulation material of economy and durability for the deficiency that overcomes prior art.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of acid and alkali-resistance anti-flaming thermal-insulation material; It is the intermediate base layer with the flame-proof polyethylene bubble layer; Attach being knotted a PET aluminizer on the upper surface of said flame-proof polyethylene bubble layer, the upper surface of a PET aluminizer attaches and is knotted the second flame-proof polyethylene bubble layer, and the upper surface of the second flame-proof polyethylene bubble layer attaches and is knotted the 2nd PET aluminizer; Attach being knotted the 3rd aluminum membranous layer on the soffit of the first flame-proof polyethylene bubble layer, the soffit of the 3rd aluminum membranous layer attaches and is knotted the 3rd flame-proof polyethylene bubble layer, and the soffit of the 3rd flame-proof polyethylene bubble layer attaches and is knotted the 4th aluminum membranous layer.
Preferably, said polyethylene anti-flaming bubble layer is made up of the air bladder that the blowing of polyvinyl interpolation fire retardant forms, and the diameter of said air bladder is the 3-30 millimeter, highly is the 3-15 millimeter.
Preferably, the thickness of said aluminum membranous layer is the 6-30 micron.
Preferably, connect through the polyurethanes coupler between said polyethylene foam layer, aluminum membranous layer, the aluminizer, the thickness of said polyurethanes coupler is the 5-30 micron.
Technique scheme has following beneficial effect: the described novel acid and alkali-resistance anti-flaming thermal-insulation material of the utility model has made full use of characteristics such as high reflection of PET aluminizer and the insulation of polyethylene foam floor height, particularly adds fire retardant and makes heat-barrier material when having highly corrosion resistant, high heat insulation, high-intensity performance, also have high flame resistance.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Fig. 1 is the structural representation of the novel acid and alkali-resistance anti-flaming thermal-insulation material of the utility model embodiment;
Wherein: 1, the first flame-proof polyethylene bubble layer; 2, a PET aluminizer; 3, the second flame-proof polyethylene bubble layer; 4, the 2nd PET aluminizer; 5, the 3rd aluminum membranous layer; 6, the 3rd flame-proof polyethylene bubble layer; 7, the 4th aluminum membranous layer.
The specific embodiment
As shown in Figure 1; The described novel acid and alkali-resistance anti-flaming thermal-insulation material of the utility model is the intermediate base layer with the first flame-proof polyethylene bubble layer 1; Attach on the upper surface of the first flame-proof polyethylene bubble layer 1 and be knotted a PET aluminizer 2; The upper surface of the one PET aluminizer 2 attaches the upper surface that is knotted the second flame-proof polyethylene bubble layer, 3, the second flame-proof polyethylene bubble layers 3 and attaches and be knotted the 2nd PET aluminizer 4; Attaching the soffit that is knotted the 3rd aluminum membranous layer 5, the three aluminum membranous layers 5 on the soffit of the first flame-proof polyethylene bubble layer 1 attaches the soffit that is knotted the 3rd flame-proof polyethylene bubble layer 6, the three flame-proof polyethylene bubble layers 6 and attaches and be knotted the 4th aluminum membranous layer 7.
Said each polyethylene foam layer is made up of the air bladder that the polyvinyl blowing forms, and the diameter of said air bladder is the 3-30 millimeter, highly is the 3-15 millimeter; The thickness of each aluminum membranous layer is the 6-30 micron.Connect through the polyurethanes coupler between each polyethylene foam layer, aluminum membranous layer, the aluminizer, the thickness of said polyurethanes coupler is the 5-30 micron.
All additional proportion is the 2%-50% nano-meter flame retardants in said polyethylene foam layer, can play better flame retardant effect like this.
Technique scheme has following beneficial effect: the described novel acid and alkali-resistance anti-flaming thermal-insulation material of the utility model has made full use of characteristics such as high reflection of PET aluminizer and the insulation of polyethylene foam floor height, particularly adds fire retardant and makes heat-barrier material when having highly corrosion resistant, high heat insulation, high-intensity performance, also have high flame resistance.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
