Abstract
Description
technical field
[0001] The invention mainly relates to a sheathing material for coal mine cables, in particular to a cold-resistant, flame-retardant and antistatic polyvinyl chloride sheathing material for coal mine cables. Background technique
[0002] Polyvinyl chloride is a polymer material, a material with good insulation performance, and its surface resistance is greater than 10 12 Ω or more, when the surface resistance of the plastic and its products is greater than 10 10 When these materials are transported, contacted, separated, rubbed and collided, they are prone to generate static electricity, and these static electricity will generate sparks when discharged in coal mines with high gas concentration, causing gas fire and explosion, causing mine disasters, and human life. Life safety and property caused incalculable losses. Especially for cables, the sheath material is mostly made of polyvinyl chloride material, which has a high surface resistance value. These...
