Anti-aging polyvinyl chloride network cable and preparation method thereof

The invention relates to an anti-aging polyvinyl chloride network cable and a preparation method thereof, and belongs to the technical field of cable material processing. The preparation method comprises the following steps: modifying polyvinyl chloride to obtain organic silicon modified polyvinyl chloride and polyvinyl chloride as base materials, adding an anti-aging additive, adding an antioxidant, a plasticizer, an ultraviolet light absorber and a flame retardant to obtain a mixture, mixing the mixture, conveying molten colloidal particles into a mold through a double-screw extruder, carrying out extrusion molding, and cooling to obtain the anti-aging polyvinyl chloride material. The anti-aging polyvinyl chloride network cable disclosed by the invention has the advantages that the MQ silicon resin is used as an anti-aging additive and is supplemented with improvement on the structure of the anti-aging additive, and the developed net structure of the MQ silicon resin further effectively improves the anti-ag
