A kind of flame resistant heat insulation material with three layers of aluminium foil layer
Technical field
The utility model relates to a kind of improvement of heat-barrier material, and particularly a kind of have high strength, high effect of heat insulation, economy and durability, a flame resistant heat insulation material with three layers of aluminium foil layer that fire resistance is good.
Background technology
Along with present global warming, in the overall situation of low-carbon economy, country encourages, promotes energy-saving and emission-reduction energetically, and environmental protection, energy saving building are important rings.The heat insulation material of Building class roof, wall that existing market is generally used is for using EPE foam or harmless cloth and the compound heat-barrier material that forms of aluminium film individual layer.It generally has shortcoming: at first, the similar material damping performances such as EPE foam or harmless cloth are poor, and easily oxidation and corrosion, and application life is low, lose gradually waterproof, heat insulation function in general two to three years; Secondly, the hot strength of the similar materials such as EPE foam or harmless cloth and lower to tensile strength in length and breadth, contact with foreign matter or weight under easily break, and relatively poor owing to surface finish, the sunray reflectivity is lower, and is heat insulation, heat-insulating property is relatively relatively poor; Again, the centre of existing heat-barrier material is without the air barrier layer, and interior outside energy easily forms convection current, conduction, and affects heat insulation usefulness; The fire resistance of existing heat-barrier material is poor, when breaking out of fire, can not satisfy fire-retardant requirement; Therefore, develop a kind of have high strength, high effect of heat insulation, economy and durability, the Novel flame-retardant heat insulating material that fire resistance is good are the relevant industries urgent problems.
The utility model content
The utility model purpose is that a kind of have high strength, high effect of heat insulation, economy and durability, the flame resistant heat insulation material with three layers of aluminium foil layer that fire resistance is good are provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of flame resistant heat insulation material with three layers of aluminium foil layer comprises the first aluminium foil layer; The downside of described the first aluminium foil layer is bonded with the first fire-retardant bubble layer; The downside of described the first fire-retardant bubble layer is bonded with the first base fabric; The downside of described the first base fabric is bonded with the second aluminium foil layer; The upside of described the first aluminium foil layer is bonded with the second fire-retardant bubble layer; The upside of described the second fire-retardant bubble layer is bonded with the second base fabric; The upside of described the second base fabric is bonded with the 3rd aluminium foil layer.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
The flame resistant heat insulation material with three layers of aluminium foil layer of the utility model scheme is provided with the first fire-retardant bubble layer, the second fire-retardant bubble layer to provide heat insulation and fire resistance; And increased the first base fabric, the second base fabric, also improved intensity when having improved heat-proof quality; Be provided with simultaneously the first aluminium foil layer, the second aluminium foil layer, the 3rd aluminium foil layer, have the characteristics such as high reflection; The utility model scheme has high strength, high effect of heat insulation, and economy and durability, fire resistance are good.
