Problems solved by technology

However, plastic pipes are very prone to static electricity, and the accumulation of static electricity may lead to static spark discharge, which may become an ignition source for underground coal dust or gas explosions; plastic pipes also have the disadvantages of flammability, low pressure resistance and low impact resistance

Abstract

The invention discloses an antistatic flame-retardant PE pipe and a preparation method thereof. The PE pipe is prepared from 4-6% of fire retardant, 0.5-1.5% of auxiliary flame retardant, 4-6% of antistatic agent and 86-91% of PE base material. The auxiliary components in the formula are concentrated first to prepare dual-resistance master batch, then the master batch is mixed with body resin in proportion, and then the materials are extruded and granulated through a twin-screw extruder. The PE pipe has the advantages of being good in ageing resistance and not prone to embrittlement, having good toughness and impact energy absorption, and being good in rapid crack resistance and corrosion resistance, free of scaling, smooth in inner wall and capable of improving the conveying capacity by 30%.

Description

technical field [0001] The invention relates to a pipe material, in particular to an antistatic flame retardant PE pipe and a preparation method thereof. Background technique [0002] At present, traditional mining pipes mainly use steel pipes, cast iron pipes, plastic pipes and glass steel pipes. Due to material problems, steel pipes and cast iron pipes are likely to collide underground and generate sparks, causing the risk of gas explosions; glass steel pipes are easily damaged by impact; plastic pipes are acid-resistant, alkali-resistant, oil-resistant, corrosion-resistant, light in weight, low in cost, and service The advantages of long service life (about 2.5 times that of steel) are unmatched by steel pipes. However, plastic pipes are extremely prone to static electricity, and the accumulation of static electricity may lead to static spark discharge, which may become an ignition source for underground coal dust or gas explosions; plastic pipes also have the disadvanta...
