[0002] PE double-wall corrugated pipe is a new type of lightweight pipe made of polyethylene as raw material through extrusion and special molding process. PE double-wall corrugated pipe has light weight, high pressure resistance, good toughness and fast construction. It has the characteristics of long service life, good corrosion resistance and high insulation that ordinary plastic pipes have. It is widely used in municipal drainage and sewage, agricultural irrigation, coal mine ventilation, chemical industry, communication cable sheathing and other fields. When the PE double-wall corrugated pipe used for drainage is used for a long time, it will be compressed by the soil above the pipe wall and cause the upper part of the pipe to collapse and deform, which will cause the diameter of the pipe to become smaller and seriously affect the water supply and drainage function of the pipe. Reshaping the collapsed pipeline to restore its original shape consumes manpower and material resources

Abstract

The invention discloses a steel wire mesh framework corrugated pipe and a preparation method thereof, and the corrugated pipe sequentially comprises a polyethylene inner pipe, a first hot melt adhesive layer, a steel wire mesh layer, a second hot melt adhesive layer and a polyethylene outer pipe from inside to outside, the polyethylene inner pipe and the polyethylene outer pipe are prepared from the following raw materials in parts by weight: 65 to 85 parts of polyethylene, 5 to 12 parts of polyoxyethylene, 15 to 35 parts of ethylene-vinyl acetate copolymer, 4 to 12 parts of modifier, 2 to 6 parts of silicon carbide micro powder, 3 to 12 parts of modified talcum powder, 5 to 15 parts of calcium stearate and 5 to 15 parts of epoxy resin. The corrugated pipe has high strength, and the steel wire mesh is clamped in the middle through the hot melt adhesive so that the strength of the corrugated pipe is improved on the premise that the original performance of the corrugated pipe is kept.
