Manufacturing method for non-excavation-purpose PE (polyethylene) water drainage pipes

Abstract

The invention discloses a manufacturing method for non-excavation-purpose PE (polyethylene) water drainage pipes. The manufacturing method comprises the following steps that a raw material is preparedby adopting the following components in percentage by weight: 70% of HDPE, 20% of a reinforcing and toughening addition agent, 5% of glass fiber, 3% of a color master and 2% of a bubble removing agent. The manufacturing method is reasonably in structure design and simple for operation; the original wide machining applicability of HDPE is maintained by the PE water drainage pipes; various types ofplastic machining can be performed; different products with qualified mechanical performance are manufactured; the compressive property of pipes is improved; the manufacturing method for the PE waterdrainage pipes is economical and practical; besides, cost is lowered as far as possible on the condition of ensuring the integral performance of the pipes; and the competitiveness of the manufacturing method is improved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a method for preparing a non-excavation polyethylene drainage pipe. Background technique [0002] PE pipe At present, in China's municipal pipe market, plastic pipes are developing steadily. PE pipes, PP-R pipes, and UPVC pipes all occupy a place. Among them, the strong development momentum of PE pipes is the most eye-catching. PE pipe At present, in China's municipal pipe market, plastic pipes are developing steadily. PE pipes, PP-R pipes, and UPVC pipes all occupy a place. Among them, the strong development momentum of PE pipes is the most eye-catching. PE pipes are used in a wide range of fields. Among them, the water supply pipe and the gas pipe are its [0003] The two largest application markets. PE resin is formed by the polymerization of monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, res...

Problems solved by technology

[0007] Although there are currently researches on the use of composite fillers for plastic modification, the balance between the basic properties of the pipe and the mechanical properties, processing properties, and compressive properties is rarely considered in the research, which leads to the performance of polyethylene pipes, especially long-term hydrostatic pressure. The test fails to meet the requirements of the standard
