Antistatic flame-retardant PE plastic pipe

Abstract

The invention provides an antistatic flame-retardant PE plastic pipe, which comprises the following raw materials (by mass): 90-110 parts of polyethylene, 5-10 parts of EVA resin, 5-15 parts of conductive graphite powder, 25-35 parts of a fire retardant, 1-5 parts of a flame retardant synergist, 0.1-1.5 parts of a coupling agent, 2-5 parts of an antioxidant, 1-2 parts of an assistant antioxidant,0.1-1.5 parts of an antistatic agent, 1-8 parts of a synergist, 0.1-1.5 parts of a dispersant, 1-6 parts of hollow glass beads, 2-4 parts of talcum powder and 2-6 parts of a stabilizing agent. The surface resistance of the conductive PE plastic pipe is stably controlled to be less than or equal to 1*105 omega, the flame retardant grade reaches V0 grade, and permanent antistatic and flame-retardanteffects are achieved.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, in particular to an antistatic and flame retardant PE plastic pipe. Background technique [0002] In the past 10 years, driven by the rapid development of my country's macro economy, my country's plastic pipes have experienced rapid development in the context of the rapid development of chemical building materials; in 2010, the national output of plastic pipes exceeded 8 million tons, of which Guangdong, Zhejiang, and Shandong accounted for the largest output. 42%; PE plastic pipes are used in chemical plants, pharmaceutical plants, machinery, environmental protection, bioengineering, mines, electric power, chemical fiber and other enterprises and industries for the transportation of flammable and explosive media, tail gas absorption, and exhaust gas discharge. The static electricity generated by pipe wall friction cannot be released. When the accumulated static electricity reaches a certain ...
