Abstract

The utility model relates to a high-performance heat-isolating flame retardant material. A flame retardant polyethylene bubble layer serves as a middle base layer; a first glass fiber layer is adhered to the upper surface of the flame retardant polyethylene bubble layer; a first aluminum film layer is adhered to the upper surface of the first glass fiber layer; a third glass fiber layer is adhered to the lower surface of the flame retardant polyethylene bubble layer; a chemically crosslinked polyethylene (XPE) foaming layer is adhered to the lower surface of the third glass fiber layer; a second glass fiber layer is adhered to the lower surface of the XPE foaming layer; and a second aluminum film layer is adhered to the lower surface of the second glass fiber layer. In the high-performance heat-isolating flame retardant material, the high strength and the high tenacity of the glass fiber layers, the high reflectivity of an aluminum film, and the high heat-preserving property and the like of the foaming material and the flame retardant bubble layer are fully used. Particularly, a fire retardant is added, so the heat-isolating material has high corrosion resistance, high heat-isolating property, high strength as well as high flame retardant property.

Description

A kind of high-performance heat-insulating flame-retardant material

Technical field

The utility model relates to a kind of fire proofing, and particularly a kind of high-performance heat-insulating flame-retardant material belongs to new material technology field.

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 fire resistance 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 for the deficiency that overcomes prior art a kind of high-performance heat-insulating flame-retardant material to be provided.

For achieving the above object; The technical scheme that the utility model adopts is: a kind of high-performance heat-insulating flame-retardant material; It is the intermediate base layer with the flame-proof polyethylene bubble layer; Attach being knotted first glass layer on the upper surface of said flame-proof polyethylene bubble layer, on the upper surface of said first glass layer, attach being knotted first aluminum membranous layer; The soffit of said flame-proof polyethylene bubble layer attaches and is knotted the 3rd glass layer; The soffit of the 3rd glass layer attaches the XPE of being knotted foamed material layer; On the soffit of said XPE foamed material layer, attach being knotted second glass layer, attach being knotted second aluminum membranous layer at the soffit of said second glass 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.

Technique scheme has following beneficial effect: the described high-performance heat-insulating flame-retardant of the utility model material has made full use of glass 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 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:

Accompanying drawing 1 is the stereogram of the high-performance heat-insulating flame-retardant material of the utility model;

Wherein: 1, flame-proof polyethylene bubble layer; 2, first glass layer; 3, first aluminum membranous layer; 4, the 3rd glass layer; 5, XPE foamed material layer; 6, second glass layer; 7, second aluminum membranous layer.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.

As shown in Figure 1; The described high-performance heat-insulating flame-retardant of the utility model material is the intermediate base layer with flame-proof polyethylene bubble layer 1; Polyethylene foam layer 1 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.Attach being knotted first glass layer 2 on the upper surface of said flame-proof polyethylene bubble layer 1, on the upper surface of said first glass layer 2, attach being knotted first aluminum membranous layer 3; The soffit of said flame-proof polyethylene bubble layer 1 attaches and is knotted the 3rd glass layer 4; The soffit of said the 3rd glass layer 4 attaches the XPE of being knotted foamed material layer 5; On the soffit of said XPE foamed material layer 5, attach being knotted second glass layer 6, attach being knotted second aluminum membranous layer 7 at the soffit of said second glass layer.

The expansion ratio that XPE foamed material layer 5 is processed by polyvinyl is that the foamed cotton of 15-50 multiplying power is formed, and the height of said 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 polyvinyl), and tensile strength is higher, and abscess is thinner.

The thickness of said each aluminum membranous layer is the 6-30 micron, and the thickness of glass layer is the 10-25 micron.

Connect through the polyurethanes coupler between said XPE foamed material layer, polyethylene foam layer, aluminum membranous layer and the glass layer, the thickness of said polyurethanes coupler is the 5-30 micron.

All additional proportion is the 2%-50% nano-meter flame retardants in said XPE foamed material layer, polyethylene foam layer and glass layer, can play better flame retardant effect like this.

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.
