Abstract

The invention discloses a polyvinyl chloride composite metal plastic pipeline and a preparation method of the polyvinyl chloride composite metal plastic pipeline. The composite pipeline is composed of a polyvinyl chloride pipe internal layer and a steel pipe external layer. The polyvinyl chloride pipe internal layer is prepared by the following raw materials,by weight, 120-130 parts of polyvinyl chloride resin, 10-16 parts of chemigum, 13-15 parts of teflon, 4-7 parts of dibutyltin maleate, 6-10 parts of nano-silicon dioxide, 2-4 parts of molybdenum disulfide, 1-3 parts of aluminium oxide, 3-5 parts of exfoliated graphite, 4-5 pats of antimonous oxide, 2-3 parts of antioxygen TNP, 3-5 parts of colouring agent, 8-12 parts of polyethyl dialcohol adipate glycol, 5-7 parts of epoxidized soybean oil, 4-6 parts of dioctyl phthalate, 6-8 parts of phthalic acid ester and 7-9 parts of promoter. By adding a performance promoter into polyvinyl chloride, the wear-resisting and corrosion-resisting property of a polyethylene pipe is improved, and the tenacity, strength and creep-resisting performance of polyvinyl chloride material is improved. According to the close combination with the metal material, the good strength and tenacity is obtained, the production technology of the composite metal plastic pipeline is greatly simplified, the production efficiency is improved, and the cost is lowered.

Description

technical field [0001] The invention relates to a composite pipe, in particular to a polyvinyl chloride steel-plastic composite pipe and a preparation method thereof. Background technique [0002] Steel-plastic composite pipe is a new type of composite pipe. The product is based on seamless steel pipe or welded steel pipe. The inner wall is coated with high adhesion, anti-corrosion, food-grade hygienic polyethylene powder coating or epoxy resin coating. The galvanized plastic-coated composite steel pipe for water supply made by pretreatment, preheating, internal coating, leveling and post-treatment process is an upgraded product of the traditional galvanized pipe, and the steel-plastic composite pipe is generally connected by threads. There are many classifications of steel-plastic composite pipes, which can be classified according to the structure of the pipe: steel strip reinforced steel-plastic composite pipe, seamless steel pipe reinforced steel-plastic composite pipe, p...
