Abstract

The invention discloses a lead-free termite-proof polyvinyl chloride (PVC) cable material and a preparation method thereof. The lead-free termite-proof PVC cable material is prepared from the following raw materials in parts by weight: 80 to 100 parts of SG-4 type PVC resin, 15 to 25 parts of polyvinylidene chloride, 10 to 15 parts of ethylene-propylene-diene monomer rubber, 14 to 18 parts of calcium silicate crystal whisker, 2 to 3 parts of magnesium oxide, 0.5 to 1.5 parts of palm wax, 5 to 10 parts of high impact polystyrene, 15 to 20 parts of fumed silica, 5 to 10 parts of precipitated barium sulphate, 10 to 15 parts of dimethyl fumarate, 1 to 2 parts of calaium strarate, 1 to 2 parts of imarcaptoacetate dioctyltin, 8 to 12 parts of talcum powder, 10 to 15 parts of aluminium hydroxide, 3 to 5 parts of epoxy octyl stearate, 0.5 to 1 part of antioxidant 168, 2 to 3 parts of termite-proof agent S-07 and 8 to 12 parts of composite filler. The cable material provided by the invention has excellent termite-proof performance, can effectively prevent communication faults and economic losses caused by termite corroding and is environment-friendly and lead-free; and the product has reliable physical and mechanical properties, excellent flame-retardant property and excellent low-smoke and low-toxicity characteristics.

Description

technical field [0001] The invention relates to a polyvinyl chloride cable material and a preparation method thereof, in particular to a lead-free anti-termite polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] The harm of termites to cables has long attracted people's attention, and the damage of termites to buried power cables and underground communication lines can be seen everywhere. Serious corrosion of PVC sheathed cables by termites occurs more frequently, resulting in failure of communication cables, communication barriers, and huge economic losses. Therefore, the market urgently needs a cable material product with anti-termite performance. Contents of the invention [0003] The object of the present invention is to provide a lead-free anti-termite polyvinyl chloride cable material and a preparation method thereof. The cable material has excellent mechanical strength and termite-proof performance. [0004] The technic...
