High-strength HDPE drainage pipe and production method thereof

Abstract

The invention discloses a high-strength HDPE drainage pipe and a production method thereof. The high-strength HDPE drainage pipe is prepared from, by weight, 30-40 parts of HDPE resin, 15-20 parts of glass fiber, 5-8 parts of calcium stearate, 1-2 parts of talcum powder, 9-15 parts of titanium dioxide, 2-4 parts of lubricant, 3-5 parts of stabilizer and 2-4 parts of processing agent. By setting a support block in a top tightening assembly, through cooperation of a rotating handle in a nut, a limiting block and a limiting groove, a swing rod on a rotating disc can be driven to rotate, then a steel ball on an ejector block on the swing rod is utilized, the ejector block can stretch out of a supporting block, and therefore the inner wall of a pipeline is tightly ejected, the pipeline can be limited through the structure, and therefore, during polishing, the position of the pipeline does not need to be corrected manually.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a high-strength HDPE drainage pipe and a production method thereof. Background technique [0002] Drainage pipes are made of polyvinyl chloride resin as the main raw material, adding appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., extruded by plastic extruder and injection molded by injection molding machine, through cooling, curing, shaping, inspection, Packaging and other processes are used to complete the production of pipes and pipe fittings. The flexibility of HDPE drainage pipes makes it easy to bend. In engineering, obstacles can be bypassed by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe fittings and installation. cost. [0003] The current drainage pipes are basically made of PE resin as the base material, so the surface is not good in terms of strength, and the current drainage pip...

AI Technical Summary

Problems solved by technology

[0003] The current drainage pipes are basically made of PE resin as the base material, so the surface is not good in terms of strength, and the current drainage pipes usually need to be polished after the production is completed, and the current pipe grinding equipment not only accounts for The ground area is large, and the structure is relatively complex, and it is often necessary to manually correct the position of the pipeline during grinding
