Abstract

The invention discloses a low-smoke flame-retardant polyvinyl chloride cable material which is composed of the following components in parts by weight: 100 parts of polyvinyl chloride, 5-20 parts of smoke-abatement flame retardant, 40 parts of plasticizer, 1 part of coupling agent, 5 parts of stabilizer and 1 part of lubricant. The smoke-abatement flame retardant is bismuth ferrite or a mixture composed of bismuth ferrite or and magnesium hydroxide in a mass ratio of (1-3):(19-1). The invention also discloses a preparation method of the cable material, which comprises the following steps: (a) weighing the components according to parts by weight; (b) drying the polyvinyl chloride and smoke-abatement flame retardant at 80-110 DEG C for 1-3 hours; and (c) mixing the dried polyvinyl chloride and smoke-abatement flame retardant with the plasticizer, coupling agent, stabilizer and lubricant, stirring uniformly, adding into a double screw extruder, and granulating. The formula is scientific and reasonable; the production technique is simple, and is easy to operate and low in cost; and the prepared cable material has the advantages of excellent flame retardancy and low smoke, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a low-smoke flame-retardant polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] Cable material is a material for wire and cable insulation and sheathing, which includes rubber, plastic, nylon and other varieties. If the flame retardant performance of the cable material is poor, the cable will easily accumulate heat during long-term work, which will cause a fire. Once a fire occurs, the direct factor that causes harm to people is often not the high temperature of the fire, but the large amount of heat generated by the burning of the cable material. Smoke, because these smokes not only contain a large amount of toxic substances, but also the high concentration of smoke is enough to suffocate people due to lack of oxygen. Therefore, the industry puts forward higher requirements on the flame retardancy, smoke emission ...
