The purpose of the utility model is realized through the following technical scheme:

the utility model provides a polymer self-adhesion waterstop, includes the HDPE base member, the upper surface and the lower surface of base member all are equipped with the storage tank, the lateral wall of storage tank is equipped with the annular boss, the top surface fixedly connected with wire net of annular boss, the thickness of wire net is less than or equal to the distance of annular boss's top surface to base member upper surface, the storage tank intussuseption is filled with the self-adhesive.

Optionally, the bottom of the accommodating groove is of a zigzag structure.

Optionally, the base body is provided with a through hole communicating the bottoms of the two accommodating grooves.

Optionally, the upper and lower surfaces of the HDPE substrate are provided with barrier films.

Optionally, a surface of the barrier film is coated with an ultraviolet resistant coating.

Optionally, four sides of the HDPE substrate are provided with splines.

Optionally, the self-adhesive is a hot melt pressure sensitive adhesive.

The utility model has the advantages of it is following: the upper surface and the lower surface of the HDPE base body of the utility model are both provided with the containing groove, the side wall of the containing groove is provided with the annular boss, the top surface of the annular boss is fixedly connected with the steel wire mesh, and the thickness of the steel wire mesh is smaller than or equal to the distance from the top surface of the annular boss to the upper surface of the base body; after filling the self-adhesive, the annular, the bottom surface of annular boss can block the self-adhesive, prevents to drop, simultaneously, because the wire net that sets up and the top surface fixed connection of annular boss, the self-adhesive that fills, wire net and annular boss form a whole, has further prevented that the self-adhesive from droing, and in addition, the wire net that sets up can also use at the waterstop, avoids the heavy stone granule in the muddy earth to glue the darker recess of self-adhesive extrusion and influence the function of self-adhesive.

Detailed Description

The technical solution in the embodiments of the present application is described below with reference to the drawings in the embodiments of the present application.

As shown in fig. 1-3, a polymer self-adhesion waterstop, includes HDPE base member 1, and the upper surface and the lower surface of base member all are equipped with storage tank 2, and the storage tank 2 intussuseption is filled with self-adhesive 4, and the lateral wall of storage tank 2 is equipped with annular boss 201, and the top surface fixedly connected with wire net 3 of annular boss 201, and fixed connection's mode can the hot melt welding, and the thickness of wire net 3 is less than or equal to the distance of the top surface of annular boss 201 to the base member upper surface.

In this embodiment, the self-adhesive glue 4 of packing is full of storage tank 2, inlays wire net 3 in self-adhesive glue 4 entirely, because the wire net 3 of setting and the top surface fixed connection of annular boss 201, the self-adhesive glue 4 of packing, wire net 3 and annular boss 201 form a whole, has further prevented that self-adhesive glue 4 from droing, and in addition, the wire net 3 of setting can also use at the waterstop, avoids the heavy stone granule in the muddy earth to extrude the darker subsides of self-adhesive glue 4 and influence the function of self-adhesive glue 4.

In this embodiment, the self-adhesive 4 is a hot-melt pressure-sensitive adhesive, and it should be noted that the pressure-sensitive adhesive refers to a kind of adhesive that is sensitive to pressure and can be adhered to an adherend under slight pressure by finger pressure without using a solvent or other auxiliary means, the hot-melt pressure-sensitive adhesive is a novel adhesive that is mixed and heated by synthetic rubber, synthetic resin, rubber oil, and the like to be in a molten state, and is a third generation pressure-sensitive adhesive product following solvent-based and emulsion-based pressure-sensitive adhesives, and compared with the former two, the hot-melt pressure-sensitive adhesive has no solvent, is more favorable for environmental protection and safe production, has high production efficiency and relatively low production cost, and is therefore widely applied to various industries at present. When the water-stop adhesive is used, the HDPE base body 1 is firmly bonded with a mud-mixed soil layer through the self-adhesive glue 4, so that a water seepage channel between the water-stop belt and the mud-mixed soil layer is sealed, and the water seepage phenomenon caused by a gap between the water-stop belt and the mud-mixed soil layer is reduced.

In this embodiment, the bottom of storage tank 2 is the zigzag structure, and the zigzag structure helps storage tank 2 bottom to adsorb self-adhesive 4 better to better prevent that self-adhesive 4 from droing.

Further, in this embodiment, the base member is equipped with the through-hole 5 of two storage tank 2 bottoms of intercommunication, the setting of through-hole 5 for from top to bottom in the storage tank 2 from the adhesive 4 form a whole, and then better avoid from the adhesive 4 from HDPE base member 1 to drop.

In the embodiment, the upper surface and the lower surface of the HDPE substrate 1 are provided with the isolating films 6, and further, the surfaces of the isolating films 6 are coated with the ultraviolet-resistant coatings which are common ultraviolet-resistant coatings on the market; when the self-adhesive waterproof and self-adhesive waterproof functions are used, the water stop and the muddy soil layer can be firmly bonded only by tearing off the isolating film 6, and the arranged isolating film 6 can protect the self-adhesive 4 from being exposed in the external environment for a long time, so that the influence on subsequent use caused by low bonding degree due to the fact that the self-adhesive 4 adsorbs impurities is avoided; the ultraviolet-resistant coating can reduce the contact of the HDPE matrix 1 with ultraviolet rays during storage, slow down aging and prolong the service life of the water stop.

In this implementation, four sides of HDPE base member 1 all are equipped with tooth's socket 7, and during the use, the tooth's socket 7 of the adjacent side of accessible is fixed waterstop and muddy soil layer, prevents that follow-up pouring process from stopping the hosepipe dislocation.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
