Abstract

The invention discloses a coal mine-use ultra-high molecular weight polyethylene antistatic flame-retardant pipe material and a preparation method thereof. The coal mine-use ultra-high molecular weight polyethylene antistatic flame-retardant pipe material is prepared from the following raw materials: by weight, ultra high molecular weight polyethylene, a flow modifier, a compatibilizer, a lubricant, an antistatic agent, a flame retardant, pretreated calcium sulfate whisker, a nucleating agent and a coupling agent. Firstly, all the raw materials are mixed in a high speed, then the mixed materials are added into an extruder for extrusion forming, and then the coal mine-use ultra-high molecular weight polyethylene antistatic flame-retardant pipe material is obtained by sizing, cooling and final cutting of the formed material. The coal mine-use ultra-high molecular weight polyethylene antistatic flame-retardant pipe material prepared by the preparation method is well plasticized and is smooth in the inner wall, the wall thickness of the continuously produced coal mine-use ultra-high molecular weight polyethylene antistatic flame-retardant pipe material can reach 40mm, flame-retardant and antistatic functions can be improved, the cost is reduced, and the production efficiency and safety coefficient are improved. Products prepared by the preparation method can completely meet the safety technology requirements of coal mine-use pipe materials.

Description

technical field [0001] The invention relates to a coal mine pipe material and a preparation method thereof, in particular to a coal mine ultra-high molecular weight polyethylene antistatic and flame-retardant pipe material and a preparation method thereof. Background technique [0002] Plastic pipes are popular and applied in many industries due to their advantages such as light weight, low price, corrosion resistance, rigidity and flexibility, wear resistance, long service life and easy installation. However, the conditions of plastic pipelines used in coal mines are harsh, and gas is a mixed negative pressure gas, which is more prone to internal explosions, so there are special requirements for antistatic and flame retardant properties of pipelines; the drop of water pipelines is large, and water hammer often occurs, which is safe The coefficient should be higher. The properties of plastic pipes such as polyvinyl chloride, polyethylene, and glass fiber reinforced plastics...
