Embodiment 1

[0013] 50 parts of high-density polyethylene, 6 parts of conductive nano-graphene, 25 parts of polyvinyl chloride, 5 parts of decabromodiphenyl ether, 5 parts of antimony trioxide, 0.5 parts of acetophenone, 2,6-tertiary butyl - 0.5 part of 4-methylphenol was put into a high mixer, and stirred at a temperature of 110° C. for 15 minutes. Put the mixed material into the extruder, the temperature of each section of the extruder screw is 150-200 ℃, the extruded material is pelletized, dried, and cooled to become an antistatic high toughness masterbatch.

[0014] Mix the masterbatch and the remaining portion of high-density polyethylene into the extruder. The length-to-diameter ratio of the extruder is 30. The temperature of each section of the extruder screw is 160-240°C. The mixture is heated at high temperature and the screw rotates. Fully mixed and extruded, the extruded material is shaped through a die, cooled, drawn, and cut to make a pipe that meets the requirements for use....

Abstract

The invention relates to a high density polyethylene pipe. An antistatic agent, a toughener, a flame retardant, a photostabilizer and an antioxidant are added into a base material of high-density polyethylene. The manufacturing technique comprises the following steps: adding 50 parts of high-density polyethylene and additives into a high-speed mixer, carrying out extrusion granulation to prepare an antistatic high-toughness master batch, mixing the master batch with the rest of high-density polyethylene, adding into an extruder, forming the extruded material through a die orifice, cooling, pulling, and cutting to obtain the pipe which conforms to the operating requirements. The high density polyethylene pipe is prepared from the following raw materials in parts by weight: 100 parts of high-density polyethylene, 3-8 parts of conducting nano graphene, 25-40 parts of polyvinyl chloride, 6-14 parts of decabromodiphenyl oxide, 7-15 parts of antimony trioxide, 0.2-0.4 part of hypnone and 0.2-0.4 part of 2,6-tert-butyl-4-methylphenol.

Description

technical field [0001] The invention relates to a polymer tubular material, in particular to a tubular material containing high-density polyethylene. Background technique [0002] Polyethylene pipe has good corrosion resistance, low cost, light weight, convenient installation and long service life, and is a good substitute for metal pipes. However, polyethylene pipes are prone to static electricity, low voltage resistance, and poor impact resistance, which limit the application range of polyethylene pipes. Polyethylene pipes have a high electrostatic charge, which can be as high as 15000V / cm in the air. Affect the subsequent processing of the product, and it is easy to absorb dust pollution during use, which not only affects the appearance of the product but also affects the performance of the product, and the discharge may cause the risk of fire or explosion. Antistatic agents can reduce the surface resistance of products, disperse the charge density on the surface of pla...
