Abstract

The invention relates to a preparation method for an environment-friendly anti-flaming anti-static polyethylene pipeline. The preparation method comprises the following steps: selecting the following components: high-density polyethylene resin, Mg(OH)2, 35-42 weight parts of phenoxy polyphosphazene elastomer, nanoscale calcium carbonate, nanoscale carbon black, silane coupling agent KH-570, pentaerythritol stearic acid amide, antioxygen 736 and antioxygen 168; preparing polyethylene master batch, mixing through a high-speed mixer, and extruding and pelletizing through a double-screw extruder; and preparing into the pipeline through the steps of extruding through a molding machine, sizing, dragging, cooling-shaping and cutting. The anti-flaming anti-static polyethylene pipeline prepared according to the method provided by the invention has the advantages that the fire retardant is high in anti-flaming efficiency, the additive amount is small, no molten drop is generated during combustion and fuming volume is small, no harmful gas is generated, and the pipeline is anti-flaming while the comprehensive mechanical property is excellent.

Description

technical field [0001] The invention relates to a preparation method of an environmentally friendly flame-retardant and antistatic polyethylene pipe, in particular to a preparation method of an environmentally friendly flame-retardant and antistatic polyethylene pipe used for transporting flammable gases such as coal gas. Background technique [0002] Polyethylene pipe is one of the most common pipes. It has the advantages of low temperature impact resistance, chemical corrosion resistance and wear resistance. It is used in water supply, drainage, heating, gas supply, agricultural irrigation, water conservancy projects and various industrial installations. be widely used. Polyethylene (PE for short) refers to a polymer formed by free radical polymerization of ethylene monomers. It is one of the most productive general-purpose plastics. Electrically insulating and chemically resistant thermoplastic. Moreover, it is easy to form and process, and is widely used in wire and ca...
