A kind of novel heat insulation material
Technical field
The utility model relates to a kind of heat-barrier material, and particularly a kind of not only have fire-retardant but also have heat insulation novel heat insulation material, belongs to technical field of novel materials.
Background technology
Along with expanding economy, the whole world increases day by day to the demand of the energy, 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 the most direct effective method of building energy conservation 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, air entrained concrete, litaflex, composite silicate thermal insulation material etc.But it generally has following shortcoming: at first, damping performance is poor, and easily oxidation and corrosion, and service 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 easily break, and surface smoothness 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, a kind of novel heat insulation material that had not only had high effect of heat insulation but also economy and durability of exploitation is the relevant industries urgent problems.
Summary of the invention
The utility model purpose is that a kind of fire-retardant heat insulation novel heat insulation material that has that both had is 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 novel heat insulation material, it is the intermediate base layer with the glass layer, the attached first fire-retardant bubble layer that is knotted on the upper surface of described glass layer, attached first aluminum membranous layer that is knotted on the upper surface of the described first fire-retardant bubble layer; The attached second fire-retardant bubble layer that is knotted on the lower surface of described glass layer, attached second aluminum membranous layer that is knotted on the lower surface of the described second fire-retardant bubble layer.
Preferably, described each fire-retardant bubble layer is made up of the air bladder that the blowing of polyethylene interpolation fire retardant forms, and the diameter of described air bladder is the 3-30 millimeter, highly is the 3-15 millimeter.
Preferably, described base fabric or nonwoven layer are made by polyethylene or polypropylene, and thickness is the 10-100 micron.
Preferably, the thickness of described each aluminum membranous layer is the 6-30 micron.
Preferably, connect by the polyurethanes coupler between described glass layer, each fire-retardant bubble layer, each aluminum membranous layer are adjacent, the thickness of described polyurethanes coupler is the 5-30 micron.
Technique scheme has following beneficial effect: novel heat insulation material described in the utility model has made full use of characteristics such as the high reflection of aluminium film, glass layer high strength, good toughness and the insulation of polyethylene foam floor height, particularly adds fire retardant and makes heat-barrier material have that highly corrosion resistant, height are heat insulation, also have high flame resistance in the high-intensity performance.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1 is the structural representation of the embodiment of the invention;
Wherein: 1, glass layer; 2, the first fire-retardant bubble layer; 3, first aluminum membranous layer; 4, the second fire-retardant bubble layer; 5, second aluminum membranous layer.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, novel heat insulation material described in the utility model is the intermediate base layer with glass layer 1, the attached first fire-retardant bubble layer 2 that is knotted on the upper surface of glass layer 1, attached first aluminum membranous layer 3 that is knotted on the upper surface of the described first fire-retardant bubble layer 2; The attached second fire-retardant bubble layer 4 that is knotted on the lower surface of described glass layer 1, attached second aluminum membranous layer 5 that is knotted on the lower surface of the described second fire-retardant bubble layer 4.Each fire-retardant bubble layer is made up of the air bladder that the polyethylene blowing forms, and the diameter of described air bladder is the 3-30 millimeter, highly is the 3-15 millimeter.The thickness of aluminum membranous layer is the 6-30 micron.All additional proportion is 30% nano-meter flame retardants in each fire-retardant bubble layer and glass layer, can play better flame retardant effect like this.Connect by the polyurethanes coupler between glass layer, each fire-retardant bubble layer, each aluminum membranous layer are adjacent, the thickness of described polyurethanes coupler is the 5-30 micron.
Technique scheme has following beneficial effect: novel heat insulation material described in the utility model has made full use of characteristics such as the high reflection of aluminium film, glass layer high strength, good toughness and the insulation of polyethylene foam floor height, particularly adds fire retardant and makes heat-barrier material have that highly corrosion resistant, height are heat insulation, also have high flame resistance in the high-intensity performance.
Below only be concrete exemplary applications of the present utility model, protection domain of the present 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.
