Development of Mine Halogen-free Flame-retarded Anti-static Polyethylene
HU Zhi
Abstract：A flame-retarded anti-static polyethylene(PE)which fully meets the requirements of coal mines was developed by taking PE as the base material and adding the halogen-free intumescent flame retardant FR-1420,the anti-static agents and the toughening agent EEA resin(ethylene-ethyl acrylate),and the effect of the flame retardant,anti-static agent and toughening agent on the properties of PE were studied and tested.The test results showed that the addition of flame retardant FR-1420 improved the flame retardant property of PE,when the mass fraction of the flame retardant reached 28%,the vertical flame class of PE reached V-0 of UL 94,and when the mass fraction of the flame retardant continuously increased to 30%,test should be made with the alcohol blast burner according to the requirements specified in Standard MT 113-1995 "The General Test Method and Decision Rule for Flame Retardant and Antistatic Properties of Polymer Products for Coal Mines";a mine halogen-free flame-retarded anti-static PE was obtained by simultaneously adding the anti-static agent and toughening agent.It was found that the halogen-free flame retardant system was not only similar to the bromine-antimony flame retardant system in the flame-retardant,anti-static and mechanical properties,but also had a high cost advantage.
