Abstract

The invention discloses a high-fire resistance modified polyethylene tube material. The high-fire resistance modified polyethylene tube material comprises high density polyethylene, silicone resin, polypropylene, an ethylene-propylene-diene monomer, maleic anhydride-grafted polyphenyl ether, tert-butyl hydroperoxide, ferriferrous oxide, barium sulfate, nanometer calcium carbonate, calcium silicate whisker, polyacrylonitrile fibers, an antistatic agent, a lubricant, an anti-oxidant and a fire retardant. The fire retardant is prepared by adding polyethylene, silicone rubber, maleic anhydride and benzoyl peroxide into a mixture, carrying out mixing to obtain a uniform mixture, adding the mixture into an extruder, carrying out primary granulation to obtain a modifier, adding aluminum hydroxide nanometer fibers, carbon nanotubes, zinc borate, magnesium hydroxide, powdered steatile and the modifier into the extruder, carrying out secondary granulation and mixing the granules, triphenyl phosphate, hydroquinol bis(diphenylphosphate) and polysulfonyldiphenylene phenyl phosphonate to obtain a uniform mixture. The high-fire resistance modified polyethylene tube material has the advantages of high strength, good pressure resistance, heat resistance, flame resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a highly flame-retardant modified polyethylene pipe. Background technique [0002] Polyethylene has high strength and can withstand a certain strain; it has good flexibility and low temperature resistance; it has excellent corrosion resistance to acidic and alkaline substances; it is light in weight, easy to process and shape, and easy to install. It is widely used in urban water supply, drainage, urban gas supply and agricultural irrigation and other fields. With the development of society, people have put forward higher requirements on the performance of polyethylene pipes. Pure polyethylene materials can no longer fully meet the needs of society, and often need to be modified by physical or chemical methods to improve their performance. However, polyethylene is a non-polar polymer, and has weak compatibility with inorganic substances and polar polymers. The strength of existing...
