figure 1 is the cross section structure schematic diagram of the high polymer self-adhesive waterproof roll of the utility model.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses a first embodiment of polymer self-adhesive waterproofing membrane, this waterproofing membrane 1 includes EVA rete 2, covers and locates the non-pitch self-adhesive precoat 3 of this EVA rete 2 second face, covers the silastic layer 4 of locating this EVA rete 2 first face, covers the nylon stratum reticulare 5 of locating this silastic layer 4 surface, covers the insulating layer 6 of locating this nylon stratum reticulare 5 surface and covers the HDPE geomembrane layer 7 of locating this insulating layer 6 surface.

Use the utility model discloses a during polymer self-adhesive waterproofing membrane 1, through set up non-pitch self-adhesive glue bed 3 at 2 second faces of EVA rete, can bond waterproofing membrane 1 in concrete structure surface, ordinary self-adhesive coiled material's 2-3 times during its peel strength. Play waterproof effect through setting up EVA rete 2, play certain antidetonation and atress cushioning effect through setting up silicon rubber layer 4, especially when appearing slightly subsiding, can play the cushioning effect, prevent that waterproofing membrane 1 from being torn. Through setting up nylon net layer 5, can play the effect that increases waterproofing membrane 1 bulk strength, prevent that the coiled material from being torn easily. Through setting up insulating layer 6, can play thermal-insulated effect, can be applied to some occasions that need insulate against heat with waterproofing membrane 1. Through setting up HDPE geomembrane layer 7, play further waterproof, corrosion-resistant effect.
