Abstract
The utility model discloses a two-sided self-adhesion waterproof roll of an EVA (ethylene vinyl acetate) composite sheet. PE (Poly Ethylene) protective films are arranged on the surface layer and the bottom layer of the waterproof roll; an intermediate layer of the waterproof roll is an EVA composite sheet; two sides of the EVA composite sheet are provided with modified asphalt self-adhesion layers, and the five layers are formed integrally; the upper and lower surfaces of the EVA composite sheet are both provided with latticed bulges; the EVA composite sheet has the thickness of 0.7-1.7mm; the waterproof roll has the thickness of 1.5-3.0mm. According to the two-sided self-adhesion waterproof roll disclosed by the utility model, the modified asphalt is used as a coating material, and is good in high and low temperature resistance; mesh-shaped reinforcing ribs are arranged, and the structural strength is high; the two-sided self-adhesion waterproof roll of the EVA composite sheet is good in adhesion resistance and resists aging; the self-adhesion of a joint of the roll is synchronous with the service life of the roll, and the roll can be used for wet construction, and has no pollution to the environment protection, is high in tensile strength, is great in ductility, and is high in applicability to stretching and cracking deformation of a base layer.
Description
Technical field
The utility model relates to waterproof building material technical field, relates in particular to a kind of EVA composite sheet double-sided self-adhesive waterproof coiled materials.
Background technology
Waterproof roll is mainly used for construction wall, roofing and tunnel, highway, refuse landfill etc. and locates, play a kind of flexible building material product that is curled into web-like of resisting extraneous rainwater, ground water seepage, as ne-leakage between engineering foundation and building, be connected, be the first barrier of whole engineering waterproofing, whole engineering is played to vital effect.
At present, polymer membranes, with its good waterproof and workability, was applied widely in recent years.Traditional polymer membranes, as poor in coiled material non-deformabilities such as PVC waterproof rolls, variations in temperature causes the convergent-divergent of coiled material, easily cause the broken micropore that forms of coiled material, affect the water resistance of waterproof roll, aspect tension, thermal adaptability, anti-aging, physical property, still needed improvement.
Utility model content
The purpose of this utility model is to overcome the deficiency in above-mentioned background technology, provides that a kind of structural strength is high, water resistance good, the new type waterproof coiled material of ageing-resistant and environmental protection.
In order to address the above problem, the technical scheme that the utility model adopts is: a kind of EVA composite sheet double-sided self-adhesive waterproof coiled materials, described waterproof roll superficial layer and bottom are PE diaphragm, described waterproof roll intermediate layer is EVA composite sheet, described EVA composite sheet both sides arrange modified pitch self-adhesion glue-line, five-layer structure one-shot forming; Described EVA composite sheet upper and lower surface is provided with latticed projection.
Preferably, above-mentioned EVA composite sheet thickness is 0.7 ~ 1.7mm, and described waterproof roll thickness is 1.5 ~ 3.0mm.
The beneficial effects of the utility model are: use modified pitch to do coating material, high and low temperature resistance is good; Netted reinforcing rib is set, and structural strength is high; Adhesive property is good, ageing-resistant, and coiled material seam self is bonding synchronizeed with the coiled material life-span; Can wet construction, environment friendly and pollution-free to environment; Tensile strength is high, percentage elongation is larger, flexible strong with the applicable ability of craze and transfiguration to basic unit.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of EVA composite sheet of the utility model double-sided self-adhesive waterproof coiled materials.
Fig. 2 is the latticed bossing structural representation of waterproof roll shown in Fig. 1.
Wherein, Reference numeral:
1-PE diaphragm, 2-modified pitch self-adhesion glue-line, 3-EVA composite sheet, the latticed projection of 4-.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similarly element numbers represents similar element.
As shown in Figure 1-2; structural representation for a kind of EVA composite sheet of the utility model double-sided self-adhesive waterproof coiled materials one embodiment; the superficial layer of waterproof roll and bottom are PE diaphragm 1, and the intermediate layer of waterproof roll is EVA composite sheet 3, and the thickness of EVA composite sheet 3 is 0.7mm.The both sides of EVA composite sheet are provided with modified pitch self-adhesion glue-line 2, five-layer structure one-shot forming, and after moulding, waterproof roll integral thickness is 1.5mm.EVA composite sheet upper and lower surface is provided with latticed protruding 4, forms reinforcing rib structure, for coiled material provides higher structural strength.
Claims (2)
1. an EVA composite sheet double-sided self-adhesive waterproof coiled materials, it is characterized in that: described waterproof roll superficial layer and bottom are PE diaphragm, described waterproof roll intermediate layer is EVA composite sheet, and described EVA composite sheet both sides arrange modified pitch self-adhesion glue-line, five-layer structure one-shot forming; Described EVA composite sheet upper and lower surface is provided with latticed projection.
2. a kind of EVA composite sheet double-sided self-adhesive waterproof coiled materials according to claim 1, is characterized in that: described EVA composite sheet thickness is 0.7 ~ 1.7mm, and described waterproof roll thickness is 1.5 ~ 3.0mm.
