Problems solved by technology

With the increase of chlorine content, the compatibility of plasticizer, low temperature resistance, compression set resistance, thermal aging performance, etc. decrease, and the water resistance is poor. When the temperature is relatively low, the material itself is relatively hard, low in elasticity and brittle. Large, low tear resistance
Since the cable sheath material used in coal mines requires that it has the characteristics of softness and good elasticity under any circumstances, chlorinated polyethylene is not suitable for coal mine cable sheath materials due to its own structure.

Abstract

The invention discloses a cable sheath material for a coal mine, which is characterized by comprising the following raw materials for preparing effective constituents according to the parts by weight: 70-100 of butyronitrile-polyvinyl chloride compound, 10-30 of neoprene, 30-60 of white carbon black, 2-8 of magnesium oxide, 20-60 of aluminum hydroxide, 30-60 of chlorcosane, 2-6 of accelerant CZ, 3-8 of zinc oxide, 1-5 of stearic acid, 3-8 of age inhibitor, 4-15 of diantimony trioxide, 2-7 of titanium pigment and 3-9 of vulcanizing agent. The cable sheath material for the coal mine has better performance of stink resistance, cold resistance, flame resistance, oil resistance, ageing resistance, and the like and has good elasticity, high tensile strength, good tear resistance, good extrusion performance and low cost.

Description

technical field [0001] The invention relates to a cable sheath material, in particular to a cable sheath material for coal mines, which belongs to the field of chemical industry. Background technique [0002] At present, the main materials commonly used in China as cable sheaths are neoprene, chlorosulfonated polyethylene rubber, chlorinated polyethylene rubber and nitrile rubber-polyvinyl chloride compound. Different structural components have different properties. Chloroprene rubber has good flame retardancy and good mechanical properties at room temperature, but when the temperature is low, the mechanical properties become poor and the cold resistance is not good. After long-term storage, it will slowly harden, lose adhesion, poor fluidity, and poor bonding performance. The price of neoprene is relatively high. If it is used alone as the main material of the cable sheath, the cost is relatively expensive. Chlorosulfonated polyethylene compound is an elastomer made of po...
