Abstract
The invention relates to a high-strength steel wire net framework polyethylene pipe. The high-strength steel wire net framework polyethylene pipe comprises an inner layer, a reinforcement layer and a protective layer, wherein the inner layer and the protective layer are both made of inflaming-retarding antistatic polyethylene materials, the reinforcement layer is composed of a steel wire net layer and a hot melt adhesive layer, a hot melt adhesive layer is arranged between the steel wire net layer and the inner layer, and another hot melt adhesive layer is arranged between the steel wire net layer and the protective layer. The steel wire net layer is composed of one or two layers of steel wire nets, hot melt adhesives are arranged between the two layers of steel wire nets, and the net holes of the outer-layer steel wire net are larger than those of the inner-layer steel wire net. Compared with the prior art, the materials of the inner layer and the outer layer of the polyethylene pipe have the inflaming-retarding and antistatic functions, and the polyethylene pipe can be used for ventilation or water feeding and drainage under a coal mine shaft; the middle reinforcement layer is a steel wire net framework composed of the steel wire nets and the hot melt adhesives, is high in strength and is low in manufacturing cost. The inner corners of the end surfaces of the polyethylene pipe are of a chamfering or arc-shaped corner structure, burr edges are not be generated at a pipe wall inner cavity in the sweat soldering process, and therefore normal flowing of media in the pipe is not hindered.
Description
Technical field
The present invention relates to polyethylene pipe, especially a kind of explosion-proof steel wire mesh framework polyethylene pipe adopting steel wire to strengthen.
Background technique
Existing polyethylene pipe or title PE pipe, generally have the PE pipe adopting separately PE material to make, the compound PE pipe also having employing PE material and steel wire or steel band to make.The PE that independent PE material is made manages relative compound PE, and to manage usual tube wall thicker, and the PE material not only used is more, and voltage endurance capability is lower, often can only be used as low-voltage tube.At present, existing steel wire or steel band PE composite pipe adopt steel wire or steel band and common PE Material cladding to make usually, and its PE material does not have fire-retardant and anti-static function usually, therefore can not be used for underground coal mine and ventilate or plumbing.
The end face of existing polyethylene pipe is all generally plane structure, the interior corner of end surfaces and outer corners are all right-angle structures, in sweat soldering work progress, because the pressure produced abutted against by two sections of pipes, the PE material after hot melt can be made to press to the both sides of seam, and form burr at tube wall inner chamber, thus the proper flow of the interior medium of impact pipe.
Summary of the invention
For the deficiency of above existing polyethylene pipe, the object of this invention is to provide one and there is fire-retardant and anti-static function, may be used for the steel wire mesh framework polyethylene pipe of underground coal mine ventilation or plumbing.
The object of the invention is by realize by the following technical solutions:
High-strength steel mesh skeleton for polyethylene pipe; high-strength steel mesh skeleton for polyethylene pipe; comprise internal layer, enhancement layer and outer surface protective layer; described internal layer is made up of flame-retardant and anti-static polyethylene material; described enhancement layer is made up of steel screen layer and heat-fusing glue layer; described protective layer is made up of flame-retardant and anti-static polyethylene material, described steel screen layer and be respectively equipped with heat-fusing glue layer between internal layer and protective layer.
As the preferred technical solution of the present invention, described steel screen layer is made up of one deck or two-layer steel wire, is provided with heat-fusing glue layer between described two-layer steel wire.
As the preferred technical solution of the present invention, the mesh of described cover wire net is greater than the mesh of steel wire of internal layer net, and described hot melt adhesive is polyethylene hot-melt adhesive.
The invention has the beneficial effects as follows: relative to prior art, the layer materials of polyethylene pipe of the present invention has fire-retardant and anti-static function, can be used in underground coal mine to ventilate or plumbing, Environmental Conditions temperature-30 DEG C is to 40 DEG C or 60 DEG C, middle reinforcement layer forms steel wire mesh frame by steel wire and hot melt adhesive, not only intensity is higher, and manufacture cost is lower.The interior corner of polyethylene pipe end face adopts chamfering or arc round angle structure, in sweat soldering process, can not form burr, thus can not hinder the proper flow of medium in pipe at tube wall inner chamber.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
Fig. 1 is structural representation of the present invention.
In figure: 1, internal layer, 2, enhancement layer, 3, protective layer, 4, heat-fusing glue layer.
Embodiment
As shown in Figure 1; high-strength steel mesh skeleton for polyethylene pipe; comprise internal layer 1, enhancement layer 2 and outer surface protective layer 3; described internal layer 1 is made up of flame-retardant and anti-static polyethylene material; enhancement layer 2 is made up of steel screen layer and heat-fusing glue layer; protective layer 3 is made up of flame-retardant and anti-static polyethylene material, steel screen layer and be respectively equipped with heat-fusing glue layer 4 between internal layer and protective layer.
In the present embodiment, described steel screen layer is made up of one deck or two-layer steel wire, is provided with heat-fusing glue layer 4 between two-layer steel wire, and the mesh of described cover wire net is greater than the mesh of steel wire of internal layer net, and hot melt adhesive is polyethylene hot-melt adhesive.The steel wire of described formation steel wire is Spring Steel Wire, the diameter of Spring Steel Wire between 1.0 to 5 millimeters, Spring Steel Wire be coated with polyethylene hot-melt adhesive, the interior corner of polyethylene pipe end face is set to chamfering or arc round angle structure.
The present invention preferably mode of execution is that enhancement layer 2 adopts two-layer steel wire to form; the mesh size of two-layer steel wire and steel wire diameter difference; can ensure that polyethylene pipe has on the basis of higher-strength; reduce internal layer 1 and protective layer 3 material used; thus reduce the thickness of tube wall further; reduce manufacture cost, and well fire-retardant and antistatic effect can be played.
