Technical field
The utility model relates to a kind of construction material, and particularly a kind of heat-barrier material of architectural usefulness belongs to building materials technology field.
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, 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 novel high-strength, heat-insulating and fire-proof heat-barrier material, it is the intermediate base layer with the flame-proof polyethylene bubble layer, attached first nonwoven or the base fabric of being knotted on the upper surface of described flame-proof polyethylene bubble layer, attached first aluminum membranous layer that is knotted on the upper surface of described first nonwoven or base fabric; Attached second aluminum membranous layer that is knotted of the lower surface of described flame-proof polyethylene bubble layer, the attached XPE foamed material layer that is knotted of the lower surface of described second aluminum membranous layer, attached second nonwoven or the base fabric of being knotted on the lower surface of described XPE foamed material layer is at attached the 3rd aluminum membranous layer that is knotted of the lower surface of described second nonwoven or base fabric.
Preferably, described flame-proof polyethylene 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.

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 high strength, heat-insulating and fire-proof heat-barrier material are the intermediate base layer with flame-proof polyethylene bubble layer 1, and flame-proof polyethylene bubble layer 1 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.Attached first nonwoven or the base fabric 2 of being knotted on the upper surface of described flame-proof polyethylene bubble layer 1, attached first aluminum membranous layer 3 that is knotted on the upper surface of described first nonwoven or base fabric 2; Attached second aluminum membranous layer 4 that is knotted of the lower surface of described flame-proof polyethylene bubble layer 1, the attached XPE foamed material layer 5 that is knotted of the lower surface of described second aluminum membranous layer 4, attached second nonwoven or the base fabric 6 of being knotted on the lower surface of described XPE foamed material layer 5 is at attached the 3rd aluminum membranous layer 7 that is knotted of the lower surface of described second nonwoven or base fabric 6.
The expansion ratio that the 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.XPE is the processes for chemically crosslinked polyethylene expanded material, is to add crosslinking agent and blowing agent with ldpe resin to form through high temperature is continuous foamed, compares with EPE (physical blowing polyethylene), and tensile strength is higher, and abscess is thinner.
The thickness of each aluminum membranous layer is the 6-30 micron, and the thickness of woven cloth or nonwoven layer is the 10-25 micron.
Connect by the polyurethanes coupler between XPE foamed material layer, flame-proof polyethylene bubble layer, each aluminum membranous layer, woven cloth or nonwoven layer are adjacent, the thickness of described polyurethanes coupler is the 5-30 micron.
All additional proportion is 35% nano-meter flame retardants in XPE foamed material layer, flame-proof polyethylene bubble layer and woven cloth or nonwoven layer, can play better flame retardant effect like this.
This high strength, high heat-insulating and fire-proof heat-barrier material have made full use of base fabric or nonwoven layer high strength, good toughness and the high reflection of aluminium film and characteristics such as expanded material and the insulation of fire-retardant bubble floor height, particularly add fire retardant and make heat-barrier material also have high flame resistance when having highly corrosion resistant, high heat insulation, 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, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
