Abstract

The invention relates to a preparation method of a polyvinyl chloride cable material, and belongs to the technical field of cable material processing. The preparation method comprises the following steps: mixing 40-60 parts by weight of polyvinyl chloride, 10-25 parts of polyurethane, 5-20 parts of bisphenol A polycarbonate, 4-6 parts of niobium pentoxide, 4-6 parts of coumarone, 3-12 parts of montmorillonite, 4-13 parts of ammonium heptamolybdate and 10-25 parts of kaolin into a high-speed mixing cylinder, starting high speed mixing for full and uniform dispersion, adding a high-temperature plasticizer and a low-temperature plasticizer sequentially, and finally adding white paraffin, an antioxidant, a heat stabilizer and zinc borate; and performing water cooling, water absorption and blow-drying processes on extruded rubber strips, and then performing granulation so as to obtain the product. The tensile strength and the tearing strength of the cable material are enhanced, meanwhile, the heat resistance and aging resistance of the cable material are improved, and the cable material is wider in application range.

Description

technical field [0001] The invention relates to a preparation method of polyvinyl chloride cable material, and belongs to the technical field of cable material processing. Background technique [0002] Polyvinyl chloride has excellent corrosion resistance, electrical insulation, especially flame resistance and self-extinguishing, so polyvinyl chloride occupies a leading position in the polymers used in wire and cable. However, polyvinyl chloride has the defects of high brittleness and poor impact resistance, and its thermal stability is not very ideal, so that it has the defect of short service life in the process of use. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a preparation method of polyvinyl chloride cable material with good thermal stability. [0004] The preparation method of the polyvinyl chloride cable material of the present invention comprises the following steps: [0005] (1), weigh the following raw materials by w...
