Abstract

The invention provides a polyvinyl chloride (PVC) cable material used in gelid state (minus 50 DEG C to minus 70 DEG C) and a preparation method of the cable material. During use, the cable material does not split and can be bent normally, thereby greatly increasing the application range of products. Moreover, the cable material is made from the following raw materials in portions by weight: PVC of 80 to 100 portions, dioctyl phthalate of 20 to 40 portions, dioctyl sebacate of 60 to 80 portions, dioctyl butane dicarboxylic acid of 4 to 8 portions, light activated calcium carbonate of 20 to 40 portions, lubricant of 1 to 3 portions , Ca-Zn composite stabilizer of 4 to 8 portions, antioxidant 1010 of 1 to 4 portions, frost resisting agent K175C of 0.5 to 5 portions and nitrile butadiene rubber of 20 to 50 portions.

Description

technical field [0001] The invention relates to a high cold-resistant polyvinyl chloride cable material and a preparation method thereof, belonging to the technical field of cable processing. Background technique [0002] At present, the lowest temperature of ordinary cold-resistant PVC cable materials is -50°C, and the cable materials are not suitable for the extreme cold environment of -70°C. The formula of the existing polyvinyl chloride cable material is (parts are parts by weight): 80-100 parts of polyvinyl chloride, 60-80 parts of dioctyl phthalate (DOP), 60-80 parts of dioctyl sebacate (DOS ) 20-40 parts, dioctyl oxalate (DOA) 4-8 parts, light active calcium carbonate 20-40 parts, lubricant (stearic acid or polyethylene wax) 1-3 parts, Ca-Zn compound 4-8 parts of stabilizer. Its processing technology is: batching - mixing - high mixing - extrusion - granulation - packaging. Contents of the invention [0003] The object of the present invention is to provide a pol...
