The utility model is set to further: described watertight composition comprises two layers of elastomer modified pitch and one deck polyurethane-base cloth, and described polyurethane-base cloth is located between elastomer modified asphalt.
By adopting technique scheme, elastomer modified asphalt and polyurethane-base cloth all have good water isolating, effectively improve the water resistance of water proof roofing sheet.Secondly, elastomer modified asphalt has certain elasticity, makes water proof roofing sheet can be good at rolling, the cracking phenomena simultaneously water proof roofing sheet can being avoided in use to occur.
The utility model is set to further: described abrasion-resistant surface layer comprises the PP film and PA film that are connected, and described PP film is connected with reflector layer.
By adopting technique scheme, PP film and PA film are transparent membrane, have good light transmission, ensure that reflector layer is to the reflection of illumination; Secondly, PA film hardness is high, and wear resistance is good, effectively prevents water proof roofing sheet surface abrasion; PP film has good water proof oxygen barrier performance, prevent seep water and and PP film under material aging phenomenon.
The utility model is set to further: described intermediate tie layer is non-woven fabrics.
By adopting technique scheme, non-woven fabrics can be fixed viscous layer, and the heat-insulation layer simultaneously after non-woven fabrics and hot melt can fit tightly, and all has good be fixedly connected with effect to heat-insulation layer, watertight composition and viscous layer.
The utility model is set to further: described viscous layer comprises the polymer that is connected from viscous oil and release liners, and described polymer is located between intermediate tie layer and release liners from viscous oil.
By adopting technique scheme, polymer is used for water proof roofing sheet from viscous oil and sticks in the sticky of roof, and the perforation avoiding screw is fixed, and release liners can facilitate installation personnel to the laying of coiled material, and water proof roofing sheet can bond by release liners of tearing.

Detailed description of the invention
With reference to Fig. 1, the utility model water proof roofing sheet embodiment is described further.
As shown in Figure 1, a kind of water proof roofing sheet, comprises PA film 11 connected successively, PP film 12, thermoplastic polyester aluminizer 2, polyethylene foamed layer 3, non-woven fabrics 4, elastomer modified asphalt 51, polyurethane-base cloth 52, elastomer modified asphalt 51, non-woven fabrics 4, polymer from viscous oil 6 and release liners 7.
PA film 11: transparent, PA film 11 hardness is high, can improve water proof roofing sheet surface abrasion resistance, prevents outer surface from scratching, and improves light transmittance; According to the PP film 12 etc. that hardness is lower, after surface scratches, light is difficult to through top layer, and reflecting effect is lower, a large amount of heats absorb by water proof roofing sheet, be difficult to the reflecting power having given play to thermoplastic polyester aluminizer 2.
PP film 12: water proof oxygen barrier, plays preliminary waterproof action on water proof roofing sheet surface, and secondly isolated air, reduces the oxidation of the internal material of waterproof roll, extends the service life of coiled material.
Thermoplastic polyester aluminizer 2: be called for short VMPET, the effect that film surface is aluminized is shading, resisting ultraviolet radiation, both the shelf-life of content had been extended, can reflect the contour thermo-optical line of sunlight, reduce coiled material to the heat absorption of light, especially under the irradiation of strong sun in summer, VMPET can by most of reflect heat, reduce roof programming rate, keep the room temperature below roofing constant.
Polyethylene foamed layer 3: be called for short EPE, it produces countless separated foams by low density polyethylene (LDPE) fat through physical blowing and forms, and has the advantages that density is little, pliability good, absorptivity is low, anti-permeability is good; Owing to having a large amount of bubbles, heat-insulating property is good, can reduce roof, room and extraneous heat transfer speed, reduce the use amount such as air-conditioning, heating installation.
Non-woven fabrics 4: non-woven fabrics 4 can be fixed viscous layer, the heat-insulation layer simultaneously after non-woven fabrics 4 and hot melt can fit tightly, and all has good be fixedly connected with effect to heat-insulation layer, watertight composition 5 and viscous layer.
Polyurethane-base cloth 52: first have higher water resistance, secondly polyurethane intensity is high, and therefore tensile property is superior, not cracky.
Elastomer modified asphalt 51: pitch has good water isolating; Secondly, be elastomer-modified pitch, there is certain elasticity, make water proof roofing sheet can be good at rolling, the cracking phenomena simultaneously water proof roofing sheet can being avoided in use to occur.
Polymer is from viscous oil 6: polymer sticks in the sticky of roof for water proof roofing sheet from viscous oil 6, and improve the fastness that water proof roofing sheet is fixing, the perforation avoiding screw is fixed, coiled material surface atresia, further enhances its barrier performance.
Release liners 7: handled easily workman is to the installation of coiled material, when needs bond water proof roofing sheet, only need the not sticky paper of white release liners 7(being similar to double faced adhesive tape) take off, the polymer of its inside is exposed from viscous oil 6, water proof roofing sheet is bonded in clean roof surface, can bonding be completed, convenient and swift.
The above makes preferred embodiment of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
