The purpose of the utility model can be realized by the following technical scheme: the utility model provides an elastomer modified asphalt waterproofing membrane, includes the coiled material body, the coiled material body include the basic unit, the basic unit on be provided with the enhancement layer, the enhancement layer up end on seted up a plurality of guiding gutters, enhancement layer bottom be provided with the water proof membrane, the enhancement layer on be provided with the crack prevention layer, the crack prevention layer coat and to have the PE rete.
Through setting up the guiding gutter, can effectively will be collected from the water of infiltration on anti-cracking layer and the PE rete, and discharge from the side of coiled material, thereby improve the waterproof nature of this coiled material, set up the water proof membrane simultaneously, avoid the further infiltration of moisture, cause the influence to the basic unit, improve the waterproof nature of this coiled material, will be used for making the coiled material surface level and smooth can not receive the fish tail through setting up the PE rete, and the PE rete has good weatherability, be convenient for prolong water proof coiled material's live time.
In the elastomer modified asphalt waterproof coiled material, the bottom of the diversion trench is arc-shaped.
In the elastomer modified asphalt waterproof coiled material, a hot melt adhesive layer is arranged between the waterproof membrane and the base layer. The setting up of hot melt adhesive layer makes waterproof membrane and basic unit inseparabler in the process of extrusion shaping combination, avoids appearing the condition of separation between the layer.
In the elastomer modified asphalt waterproof coiled material, the bottom of the base layer is provided with the high-viscosity adhesive film. The adhesive force between the coiled material and the external structure is larger and more stable.
In the elastomer modified asphalt waterproof coiled material, the joint surfaces of the anti-cracking layer and the PE film layer are in zigzag matching. The zigzag shape avoids the phenomenon of separation of the two layers.
In the elastomer modified asphalt waterproof coiled material, the anti-cracking layer is alkali-resistant glass fiber mesh cloth. The anti-cracking layer can effectively prevent the coiled material from cracking.
In the elastomer modified asphalt waterproof coiled material, one side of the surface of the coiled material body is fixedly provided with a tearing groove. The waterproof roll is more convenient and faster to tear when being taken.
In the elastomer modified asphalt waterproof coiled material, the base layer is a modified asphalt layer.
Compared with the prior art, the utility model can effectively collect water permeating from the anti-cracking layer and the PE film layer by arranging the diversion trench and discharge the water from the side edge of the coiled material, thereby improving the waterproofness of the coiled material.
