Technical field
The utility model relates to a kind of constructional materials, and particularly a kind of heat-barrier material of architectural usefulness belongs to the material technology field.
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 building class roof that existing market is generally used, the heat insulation material of wall are for EPE foam or harmless cloth and the aluminium film individual layer heat-barrier material that forms such as compound.But it generally has shortcoming: at first, class material damping performances such as EPE foam or harmless cloth are poor, and easily oxidation and corrosion, and application life is low.Lost 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 relatively poor owing to surface finish, 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, and influences heat insulation usefulness.Therefore, develop a kind of not only had higher-strength and elasticity and can be anti-oxidant and 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.
The utility model content
The utility model purpose is to provide a kind of to have higher-strength and elasticity can the anti-oxidant and corrosion-resistant novel heat insulation material that also has high effect of heat insulation, economy and durability 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 heat-barrier material for building, comprise the XPE foamed material layer, attached first polyethylene layer that is knotted on the upper surface of described XPE foamed material layer, the attached polyester polymer thin layer that is knotted on the upper surface of described first polyethylene layer, attached first aluminum membranous layer that is knotted on the upper surface of described polyester film layer, attached second polyethylene layer that is knotted on the soffit of described XPE foamed material layer, attached woven cloth or the nonwoven layer that is made by polyethylene or polypropylene that be knotted on the soffit of described second polyethylene layer is at also attached second aluminum membranous layer that is knotted of the outer surface layer of woven cloth or nonwoven layer.
Preferably, the expansion ratio that described XPE foamed material layer is made by polyethylene is that the foamed cotton of 15-50 multiplying power is formed, and the height of described foamed cotton is the 3-15 millimeter.
Preferably, the thickness of described first polyethylene layer, second polyethylene layer is the 10-50 micron, the thickness of described polyester polymer thin layer is the 10-25 micron, the thickness of described first aluminum membranous layer, second aluminum membranous layer is the 6-30 micron, and the thickness of described base fabric or nonwoven layer is the 10-100 micron.
Preferably, connect by polyurethanes coupler or polyethylene or polypropylene between described XPE foamed material layer, first polyethylene layer, second polyethylene layer, polyester polymer thin layer, base fabric or nonwoven layer, first aluminum membranous layer are adjacent with second aluminum membranous layer, described polyurethanes coupler or polyethylene or polyacrylic thickness are the 5-30 micron.
Technique scheme has following beneficial effect: this heat-barrier material for building has made full use of base fabric or characteristics such as high reflection of nonwoven layer high strength, good toughness and aluminium film and the high insulation of XPE expanded material, makes the heat-barrier material of preparation promptly have high flame retardant, high heat insulation while and also has excellent properties such as highly corrosion resistant, high strength, height insulation.
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 utility model embodiment;
Wherein: 1, XPE foamed material layer; 2, first polyethylene layer; 3, polyester polymer thin layer; 4, first aluminum membranous layer; 5, second polyethylene layer; 6, woven cloth or nonwoven layer; 7, 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, this heat-barrier material for building is the intermediate base layer with XPE foamed material layer 1, XPE is the processes for chemically crosslinked polyethylene expanded material, be to add crosslinking agent and blowing agent with ldpe resin to form through high temperature is continuous foamed, compare with EPE (physical blowing polyethylene), tensile strength is higher, and abscess is thinner.The expansion ratio that XPE foamed material layer 1 is made by polyethylene is that the foamed cotton of 15-50 multiplying power is formed, and the height of described foamed cotton is the 3-15 millimeter.Attached first polyethylene layer 2 that is knotted on the upper surface of XPE foamed material layer, the attached polyester polymer thin layer 3 that is knotted on the upper surface of first polyethylene layer, attached first aluminum membranous layer 4 that is knotted on the upper surface of polyester film layer 3; Attached second polyethylene layer 5 that is knotted on the soffit of XPE foamed material layer 1, attached woven cloth or the nonwoven layer 6 that is made by polyethylene or polypropylene that be knotted on the soffit of second polyethylene layer 5 is at attached second aluminum membranous layer 7 that is knotted of the outer undersurface layer of woven cloth or nonwoven layer 6.
The thickness of first polyethylene layer 2, second polyethylene layer 5 is the 10-50 micron, the thickness of polyester polymer thin layer 3 is the 10-25 micron, the thickness of first aluminum membranous layer 4, second aluminum membranous layer 7 is the 6-30 micron, and the thickness of woven cloth or nonwoven layer 6 is the 10-100 micron.All by polyurethanes coupler or polyethylene or polypropylene connection, polyurethanes coupler or polyethylene or polyacrylic thickness are the 5-30 micron between air bladder, first polyethylene layer 2, polyester polymer thin layer 3, first aluminum membranous layer 4 and second polyethylene layer 5, woven cloth or nonwoven layer 6 and second aluminum membranous layer 7.All additional proportion is 15% nano-meter flame retardants on XPE foamed material layer 1, first polyethylene layer 2, second polyethylene layer 4, polyester polymer thin layer 3, woven cloth or nonwoven layer 6, can play better flame retardant effect like this.
This heat-barrier material for building has made full use of woven cloth or characteristics such as high reflection of nonwoven layer high strength, good toughness and aluminium film and the high insulation of XPE expanded material, makes the heat-barrier material of preparation promptly have high flame retardant, high heat insulation while and also has excellent properties such as highly corrosion resistant, high strength, height insulation.
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, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
