Problems solved by technology

[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. Incalculable loss of life safety and property
Especially for cables, the sheath material is mostly made of polyvinyl chloride material, which has a high surface resistance value. These cables will often move underground in coal mines, and collide and rub with other high-resistance materials, which will generate static electricity. and sparks, a threat to mine safety
Although there are many antistatic PVC materials, they are all hard materials molded to make antistatic pipes, which cannot be bent and moved repeatedly, and cannot be used on cable sheaths that need to be dragged and moved frequently, and many Antistatic PVC materials are sprayed with antistatic materials on the surface to achieve antistatic effects, but this method cannot achieve permanent antistatic, nor can it withstand the immersion of coal mine water for a long time

Abstract

The invention discloses a cold-resistance flame-retardant anti-static polyvinyl chloride sheathing material for coal mine cable; the sheathing material is characterized by consisting of the following raw materials: polyvinyl chloride resin SG3, tri(2-chloroethyl) phosphate, an anti-static agent, dioctyl sebacate, dioctyl phthalate, tricresyl phosphate, antimonous oxide, zinc borate, tribasic lead sulfate, bibasic lead sulfate, light calcium carbonate, bisphenol A, 2-mercapto benzimidazole, vinyl tri(beta-methoxyl ethyoxyl) silane, accelerant TMTD and modified asbestos powder; the polyvinyl chloride sheathing cable material provided by the invention has the following characteristics of being low in surface resistance value and high in anti-static property; by adopting the compound high-concentration anti-static agent consisting of TCEP (trichloroethyl phosphate), quaternary ammonium salt cationic surface active agent and nonionic surface active agent, the excellent anti-static synergistic effect can be brought; the surface resistance value of the sheathing material is no higher than 108ohms, and thus the sheathing material has excellent anti-static property.

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...
