Abstract

The invention relates to a preparation method for a flame-retardant and antistatic pipeline with high strength, wherein no degradation on the other performances of the flame-retardant and antistatic pipeline with high strength is realized to a certain extent while an inorganic modifier is greatly enhanced. Simultaneously, the crystallization of polyethylene realizes the effect of heterogeneous nucleation by using a small amount of nanometre materials. Additionally, the flame-retardant and antistatic pipeline with high strength enables to have a flame-retardant characteristic, and the resistivity thereof is decreased until electrostatic charges can be rapidly leaked by adding a flame retardant and a filler with a certain conductivity, so as to achieve the application demands of fire prevention, electrostatic prevention etc.

Description

technical field [0001] The invention relates to a preparation method of a high-strength flame-retardant and antistatic pipeline, in particular to a preparation method of a flame-retardant and antistatic steel mesh skeleton polyethylene composite pipe. Background technique [0002] In the prior art, steel pipes and plastic pipes are commonly used underground in coal mines. Steel pipes are easy to rust, not resistant to corrosion, short in life, difficult to install, and difficult to guarantee the quality of welding, so they are gradually replaced by corrosion-resistant plastic pipes. Especially when plastic polyethylene pipe products are used underground in coal mines, metal mines or non-metal mines. Since the 1990s, the annual sales volume of plastic pipes has increased by about 23%. However, the vast majority of plastic products are combustible and difficult to extinguish. The accidents caused by the burning of plastic products have become a serious social problem. There ...
