PE antistatic anti-radiation mining pipe fitting

Abstract

The invention discloses a PE anti-static and anti-radiation electric mine pipe fitting, which is made of a base pipe and a functional layer, and the functional layer includes the following components in terms of mass percentage: polyethylene 15‑50wt.%, corn Starch 15-50wt.%, cobalt acetylacetonate 20-55wt.%, potassium titanate whisker reinforcement 0.1-2.0wt.%, antimony pentafluoride 0.05-1.0wt.%, furan resin 0.1-1wt.%. An antistatic coating is arranged between the base pipe and the functional layer, and the antistatic coating is composed of ethyl silicate paint. The antistatic coating composed of the ethyl silicate system of the present invention has good electrical conductivity, and its effects of removing static electricity and anti-radiation are very stable and extremely good.

Description

technical field [0001] The invention relates to a PE antistatic and antiradiation electric mine pipe fitting. 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 that have been used are not easy to meet the strict technical requirements of coal mine pipes, especially in terms of wear resistance, tensile str...

AI Technical Summary

Problems solved by technology

Since the performance of the existing ordinary plastic pipes cannot meet the safety technical requirements of pipes used in underground coal mines, it is necessary to develop and research a plastic pipe with better performance to meet the strict requirements of pipes used in underground coal mines

[0003] However, the existing pipe fittings have poor antistatic and radiation protection performance, so it is urgent to develop a product with good antistatic and radiation protection performance.
