Ultra high molecular weight polyethylene and polyvinyl chloride composite pipe embedded with reinforced steel filaments and manufacturing method thereof

Abstract

The invention discloses an ultra high molecular weight polyethylene and polyvinyl chloride composite pipe embedded with reinforced steel filaments and a manufacturing method thereof. The ultra high molecular weight polyethylene and polyvinyl chloride composite pipe is characterized in that: an inner layer is an ultra high molecular weight polyethylene pipe; an outer layer is a polyvinyl chloride pipe; the steel filaments are arranged between the inner layer and the outer layer; more than one fifth of the diameter of the steel filaments is embedded into the outer wall of the inner layer ultra high molecular weight polyethylene pipe, wherein the polyvinyl chloride outer wall is added with an impact modifier, a heat stabilizer, a lubricant and other PVC processing aids. The invention provides the ultra high molecular weight polyethylene and polyvinyl chloride composite pipe, which not only has the characteristics of wear resistance, corrosion resistance and difficult adhesion of the ultra high molecular weight polyethylene pipe, but also has the good performance of high strength and creep resistance of the reinforced polyvinyl chloride material; the inner and outer wall of the pipe are corrosion resistant; and the pipe is compounded by hot melting the ultra high molecular weight polyethylene inner pipe, the polyvinyl chloride outer wall and the embedded steel filaments, the combined strength of the three materials is greatly improved, and the problem of combination of different materials is radically solved when the three materials are firmly combined.

Description

technical field [0001] The invention relates to an ultra-high molecular weight polyethylene polyvinyl chloride composite pipe embedded with reinforced steel wire and a manufacturing method thereof. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) pipes are wear-resistant, corrosion-resistant, chemically stable, and have low surface polarity. fluid material. However, there are deficiencies in tensile strength, low shear strength, and poor creep resistance, which limit its application. [0003] Polyvinyl chloride (PVC) material has high tensile strength, high impact strength, and good rigidity, but its wear resistance, anti-adhesion, and solvent resistance are far inferior to ultra-high molecular weight polyethylene pipes, and it is difficult to meet relevant sanitary technical standards. Its application is also limited. [0004] The metal-plastic composite pipe in the prior art improves the strength of the plastic pipe and solves the corrosio...

Problems solved by technology

This patent solves the technical problem of ultra-high molecular weight polyethylene high-strength steel wire composite pipes, but it needs to use hot melt adhesive multiple times, and the radiation cross-linked polyethylene stretch tape wrapped in a sheet-like spiral winding on the outer wall of the steel wire is not easy to realize continuous production
