HDPE (high-density polyethylene) double-wall corrugated pipe

Abstract

The invention discloses an HDPE (high-density polyethylene) double-wall corrugated pipe. The pipe comprises the following raw materials in parts by weight: 15-55 parts of HDPE, 3-18 parts of LDPE (low-density polyethylene), 6-24 parts of LLDPE (linear low-density polyethylene), 2-20 parts of EVA (ethylene vinyl acetate), 4-18 parts of drawing grade polypropylene, 5-10 parts of attapulgite powder, 1-10 parts of white carbon black, 1-10 parts of zirconium sulfate, 10-20 parts of graphite, 5-15 parts of nano-carbon, 8-20 parts of polyimide fiber, 0.5-4 parts of a silane coupling agent KH151, 1-2 parts of diphenyl ketone, 1-10 parts of a composite lubricating agent, 0.01-0.2 part of nano-silver, 0.5-5 parts of flavonols, 0.5-5 parts of zinc stearate, 1-5 parts of polyacrylamide, 5-10 parts of methyl methacrylate, 1-5 parts of 2, 4-dichlorobenzoyl peroxide and 10-20 parts of 6-ethoxy-2, 2, 4-trimethyl-1, 2-dihydroquinoline. According to the pipe prepared from the raw materials disclosed by the invention, mechanical properties, impact resistance, deformability, anti-aging performance and anti-fouling performance are obviously and greatly upgraded.

Description

Technical field [0001] The present invention involves a HDPE double -wall ripple, which is the field of plastic pipe technology. Background technique [0002] PE double -wall ripples were successfully developed in Germany in the early 1980s.PE double -wall ripples are a new light pipes made of polyethylene as the raw material squeezed out and special formation process. The inner wall is smooth and the outer wall is a closed ripple type.In addition to the characteristics of good corrosion resistance, high insulation, smooth inner walls, and small flow resistance in ordinary plastic pipes, they also have special hollow ring structures.The characteristics of strength and toughness, light weight, strong impact resistance, and not easy to damage. [0003] At present, the formal situation of the production of PE double -wall ripples in my country is: low -pressure polyethylene (HDPE)+enhanced filling mother material (calcium carbonate mother granules)+color mother, such a traditional m...

Problems solved by technology

However, there is currently a lack of special bonding resins suitable for steel wire skeleton reinforced polyethylene pipes. The pipes formed by existing resins have poor mechanical properties, impact resistance, deformability, aging resistance, and anti-fouling properties.
