example 1

[0017] A kind of preparation method of antistatic polyethylene pipe material, its preparation method is as follows:

[0018] (1) Add 100 parts by weight of ultra-high molecular weight polyethylene, 25 parts of polyvinyl chloride, 12 parts of polyolefin, 1.5 parts of fluorinated graphite, and 1 part of white oil into a twin-screw extruder to prepare Get particles;

[0019] (2) Put the granules prepared in step (1) into a single-screw extruder to extrude the pipe. The temperature of the barrel of the single-screw extruder is 135°C, the temperature of the mold is 165°C, and the die opening temperature is 140°C .

example 2

[0021] A kind of preparation method of antistatic polyethylene pipe material, its preparation method is as follows:

[0022] (1) Add 90 parts by weight of ultra-high molecular weight polyethylene, 15 parts of polyvinyl chloride, 10 parts of polyolefin, 1.5 parts of fluorinated graphite, and 0.8 parts of white oil into a twin-screw extruder to prepare Get particles;

[0023] (2) Put the granules prepared in step (1) into a single-screw extruder to extrude the pipe. The temperature of the barrel of the single-screw extruder is 135°C, the temperature of the mold is 165°C, and the die opening temperature is 140°C .

[0024] In summary, polyvinyl chloride has flame retardancy (flame retardancy value above 40), high chemical resistance (resistance to concentrated hydrochloric acid, sulfuric acid with a concentration of 90%, nitric acid with a concentration of 60% and sodium hydroxide with a concentration of 20% ), good mechanical strength and electrical insulation, polyethylene is...

Abstract

The invention relates to an anti-static polyethylene pipe, comprising the following components in parts by weight: 78-105 parts of ultra-high molecular weight polyethylene, 15-35 parts of polyvinyl chloride, 10-18 parts of polyolefin, 1.2-5 parts of fluorine fossils and 0.6-1.5 parts of white oil. The invention also provides a preparation method of the anti-static polyethylene pipe. The anti-static electricity capacity of the anti-static polyethylene pipe prepared from the components is obviously better than that of a common polyethylene pipe.

Description

technical field [0001] The invention belongs to the technical field of engineering plastics, in particular to an ultra-high molecular weight polyethylene pipe and a preparation method thereof. Background technique [0002] Polyethylene has incomparable wear resistance, impact resistance, chemical resistance and self-lubricating properties compared to other engineering plastics. It is widely used in various fields of the national economy, especially in wear-resistant transportation, equipment linings, various mechanical parts, etc. With unique advantages, the development and application of its products have broad prospects, and the development of new application fields is attracting people's attention. [0003] However, since polyethylene is a typical insulating material, the pipes made of it are prone to static electricity during use, which affects the practical application of the pipes. Contents of the invention [0004] The technical problem to be solved by the present ...
