Special material for antistatic impact fire resistant polyethylene pipe

Abstract

An antistatic, anti-impact and flame-retarded polyethene used for pipeline is proportionally prepared from high-density polyethene, antistatic agent, flame retarder, flame-retarded synergist, toughening agent, optical stabilizer and antioxidizing agent through mixing part of polyethene with others, extruding out to become particles, mixing with rest of polyethene, dual-screw extruding out, cooling, drying and cutting to become particles.

Description

Technical field:

[0001] The invention relates to a special antistatic anti-shock flame-retardant polyethylene pipe material and a preparation method thereof. Background technique:

[0002] At present, the ventilation pipes, water pipes and gas drainage pipes in coal mines are made of metal pipes such as cast iron pipes, which have the disadvantages of easy rust and corrosion, inconvenient installation, short service life, frequent maintenance, and high overall cost. Although plastic pipes can To overcome the above-mentioned shortcomings of metal pipes, but the antistatic performance and impact resistance of plastic pipes are poor, and they are easy to burn. The existing plastic pipes for coal mines reduce the impact strength of the pipes due to the addition of a large amount of antistatic agents and flame retardants. It is difficult to achieve a comprehensive balance of antistatic performance, impact resistance and flame retardant performance, which greatly limits the furthe...
