▎ 摘　　要

NOVELTY - Modified polyvinyl chloride cable material comprises modified polyvinyl chloride resin, ultraviolet absorber, antioxidant, flame retardant, preservative, light calcium carbonate, graphene, and turpentine, where modified polyvinyl chloride resin is prepared by dissolving polyvinyl chloride resin in an organic solvent, adding potassium carbonate and thiosalicylic acid, reacting at 60 degrees C for 10-15 hours under the protection of nitrogen, and pouring into methanol/water mixture In the liquid to obtain white lumpy solid after vacuum drying. This solid is further dissolved with tetrahydrofuran, the pH is adjusted to 5 with hydrochloric acid, and then poured into methanol to precipitate and dried under vacuum to obtain white powder. The white powder, plasticizer DOP, and maleic anhydride are added to a high-speed mixer, mixed them at 160 degrees C for 3 minutes, then added kaolin, and continue mixed for 5 minutes to obtain modified polyvinyl chloride resin. USE - Modified polyvinyl chloride cable material. ADVANTAGE - The modified polyvinyl chloride cable material has good mechanical properties, high temperature resistance, aging resistance and flame retardant properties, safety and environmental protection. DETAILED DESCRIPTION - Modified polyvinyl chloride cable material comprises modified polyvinyl chloride resin, ultraviolet absorber, antioxidant, flame retardant, preservative, light calcium carbonate, graphene, and turpentine, where modified polyvinyl chloride resin is prepared by dissolving polyvinyl chloride resin in an organic solvent, adding potassium carbonate and thiosalicylic acid, reacting at 60 degrees C for 10-15 hours under the protection of nitrogen, and pouring into methanol/water mixture In the liquid to obtain white lumpy solid after vacuum drying. This solid is further dissolved with tetrahydrofuran, the pH is adjusted to 5 with hydrochloric acid, and then poured into methanol to precipitate and dried under vacuum to obtain white powder. The white powder, plasticizer DOP, and maleic anhydride are added to a high-speed mixer, mixed them at 160 degrees C for 3 minutes, then added kaolin, and continue mixed for 5 minutes to obtain modified polyvinyl chloride resin. The volume ratio of methanol and water in the methanol/water mixed solution is 1:1, and ratio of the polyvinyl chloride resin, potassium carbonate and thiosalicylic acid is 1:1.5: 2. The mass ratio of the white powder, plasticizer DOP, maleic anhydride and kaolin is 10: 2: 5: 1. An INDEPENDENT CLAIM is included for a method for preparing modified polyvinyl chloride cable compound, which involves weighing out each component of the flame retardants, drying, grinding and mixing;#drying the modified polyvinyl chloride resin, add ultraviolet absorber, antioxidant, preservative, light calcium carbonate, graphene and turpentine, and heating to 50 degrees C and stirring and mixing well, adding the treated flame retardant, and mix and extrude pellets in a kneading extruder to obtain the modified polyvinyl chloride cable material.
