Embodiment Construction

[0016] Embodiments of the present invention will now be described in detail. An alloy material for polyethylene pipes for water supply, the material components of which are as follows in terms of percentages:

[0017]

[0018] The preparation process of the present invention is as follows:

[0019] 1. According to the proportion and serial number of the raw material components, put them in the container of the high-speed mixer in sequence, then turn on the power switch and stir for 5-10 minutes, and the motor speed is ≥ 750 rpm. After the materials are evenly mixed, turn off the power switch and draw out Material baffle, so that the mixture slowly flows into the barrel for use in the next process.

[0020] Raw material formula→high temperature mixing→(60—70℃ / 10min)→cooling and dispersing→(10—20℃ / 10min)→store in barrel.

[0021] 2. Inhale the mixture in the barrel into the barrel of the extruder, then turn on the power switch and slowly turn the control knob of the reducer...

Abstract

The invention discloses an alloy material of a polyethylene pipeline for water supply and a preparation method. The alloy material comprises the following components in percentage: 64.56%-63.22% of PE100s, 32.28%-31.61% of PE100RC, 0.46%-0.95% of polyoxyethylene [CH2-CH2-O]-n, 0.46%-0.57% of 2,4-hexadienoic acid C6-H8-O2, 0.33%-0.51% of 2-(2-hydroxyl-3-tert-butyl-5-methyl phenyl)-5-chlorobenzene triazole and 1.94%-3.17% of maleic anhydride C4H2O. According to the invention, optimized material configuration, matched manufacturing process and deep processing value-added treatment are carried out according to the technical index requirements and use conditions of the pipe, so that the physical and chemical properties, yield and long-term stability of the pipe are improved.

Description

technical field [0001] The invention relates to a polyolefin material used in pipes for water supply and drainage pipe network projects, in particular to an alloy material and a preparation method of polyethylene pipes for water supply. Background technique [0002] At present, the polyethylene (PE) pipes for water supply produced and processed by domestic pipe enterprises are all processed by blending and extruding PE100s or PE80s with black masterbatch. Deep processing and value-added treatment of optimized ingredients and matching processes are not combined with national quality standards and technical conditions for use. It is not conducive to the mechanical properties of pipes that are resistant to slow crack growth when they are used under high temperature conditions or under point loads, as well as improving the delivery flow, preventing water pollution, and prolonging the service life. Contents of the invention [0003] In view of the technical problems in the bac...
