A kind of Novel steel wire network framework compound plastic pipe, the tube wall of described tubing is three-decker, internal layer is the HDPE material, in order to be coated by HDPE, the winding steel wire net forms and skin is the HDPE material in mesosphere.
Further, described internal layer and the outer HDPE material that adopts same tubing level.
Further, described internal layer and the outer HDPE material that adopts not same tubing level.
Further, described winding steel wire net divides two-layer being wrapped on internal layer, and before being wound around, Steel Wire Surface has coated one deck hot melt adhesive.
Further, it is 2-5mm that described hot melt adhesive coats thickness, density>=0.94g/cm
3, melt index (g/10min)>=1.5, Vicat softening point>=120 ℃, elongation at break>=500%.
Compared with prior art, the utility model has the advantage of:
The technological means of employing of the present utility model is to change existing steel wire mesh frame plastic composite tube equipment structure and the mode of production, pipe structure changes three layers into by five layers, two-layer hot melt adhesive special layer in the middle of removing, increasing steel wire crosses glue and crosses the glue bondline thickness, the gap that two-layer HDPE can see through between the winding steel wire layer directly is melted into one, thereby greatly improves the tubing peeling strength.And the preparation method just has the change of two aspects with original cardinal principle: the one, strengthen winding steel wire and coat hot melt adhesive special thickness, heat-fusing glue layer thickness increases 1-2mm; The 2nd, when producing, with HDPE, replace hot melt adhesive co-extrusion parcel to cross the winding steel wire stratum reticulare of glue, well improved the stability of production, reduced reject rate, improved quality of product.
