Abstract

The invention discloses a degradable ultra-high molecular weight HDPE composite plastic double-wall corrugated pipe. The double-wall corrugated pipe contains the following components in parts by weight: 40-60 parts of HDPE, 8-18 parts of chlorinated polyethylene, 3-9 parts of polybenzimidazole fibers, 4-10 parts of carbon fibers, 4-12 parts of graphene particles, 3-9 parts of carbon nanotubes, 2-4parts of an antibacterial toughening master batch, 3-9 parts of light calcium carbonate, 5-12 parts of attapulgite powder, 4-10 parts of oxidized polyethlene wax, 1-3 parts of nano-titanium dioxide,1-3 parts of nano-scale silica powder, 1-2 parts of nano-silver and 4-10 parts of a cross-linking agent. The preparation method is simple and good in environmental protection performance. The prepareddouble-wall corrugated pipe has excellent pressure resistance, wear resistance, corrosion resistance and high-temperature resistance and simultaneously has an anti-leakage effect and a long service life.

Description

technical field [0001] The invention relates to the technical field of double-wall corrugated pipe preparation, in particular to a degradable ultra-high molecular weight HDPE composite plastic double-wall corrugated pipe. Background technique [0002] PE double-wall corrugated pipe was first successfully developed in Germany in the early 1980s. PE double-wall corrugated pipe is a new type of lightweight pipe made of polyethylene as raw material through extrusion and special molding process, with smooth inner wall and closed corrugated outer wall. PE double-wall corrugated pipe not only has the characteristics of good corrosion resistance, high insulation, smooth inner wall and small flow resistance that ordinary plastic pipes have, but also has excellent ring stiffness and good rigidity due to the special hollow ring structure. Strength and toughness, light weight, strong impact resistance, not easy to break and so on. [0003] At present, the current formula of PE double-...
