Abstract

The invention relates to the technical field of pipes. The invention relates to a corrosion-resistant PE water supply pipe and a preparation method thereof. The corrosion-resistant PE water supply pipe is prepared from the following raw materials in parts by weight: 60 to 80 parts of PE resin powder, 20 to 30 parts of a regenerated polyethylene material, 10 to 16 parts of organic silicon rubber, 5to 10 parts of a polyacrylamide / nano metal quantum dot composite material, 4 to 8 parts of modified nano graphene, 3 to 6 parts of organic montmorillonite, 2 to 4 parts of polylactic acid fibers, 1.5to 3.5 parts of an antioxidant, 1 to 3 parts of a silane coupling agent and 0.5 to 1 part of a lubricant. The PE water supply pipe has good corrosion resistance, can resist corrosion of various chemical media, especially acid, alkali, salt and oil, and is free of electrochemical corrosion, high in environmental adaptability, free of rotting and corrosion after being used for a long time, durable,simple in preparation method, easy to operate and good in market prospect.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a corrosion-resistant PE water supply pipe and a preparation method thereof. Background technique [0002] PE is polyethylene. Generally, the application range of PE pipes for water supply pipes is below 40°C, and cannot be used for hot water pipelines. PE pipes are a kind of high crystallinity, non-polar thermoplastic resin, and the appearance of original HDPE It is milky white and translucent to a certain extent in the thin section. PE has excellent resistance to most domestic and industrial chemicals. Certain types of chemicals will cause chemical corrosion, such as corrosive oxidizers (concentrated nitric acid), Aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). my country's plastic pipes are developing rapidly, and the quality is constantly improving. At present, the plastic pipe industry mainly composed of polyvinyl chloride (PVC-U) pipes, po...
