Embodiment Construction

[0010] A water-resistant and flame-retardant PVC cable sheathing material, made of the following raw materials (kg): SG-4 type polyvinyl chloride resin 80, polyetheretherketone 20, ABS10, diisodecyl phthalate 10, Dibutyl maleate 8, fumed white carbon black 20, calcium zinc composite stabilizer 1.5, barium stearate 2, tris(xylene) phosphate 10, palm wax 4, magnesium hydroxide 12, decabromodi Phenyl ethyl 8, zinc borate 5, pumice powder 8, nano barium titanate 10, composite filler 4;

[0011] The preparation method of the composite filler is as follows: a. Take bentonite, barite, and monazite in a weight ratio of 4:4:2, then add 2% coal powder and 1% activated carbon by weight of bentonite, and mix them uniformly at 550 ° C. Calcined for 4 hours, cooled to room temperature, crushed to a particle size below 15 μm, then added water to make a slurry with a concentration of 45%, added hydrochloric acid solution with a concentration of 12% to adjust the pH of the slurry to 5.5, heate...

Abstract

The invention discloses a waterproof flame-retardant PVC cable sheath material and a preparation method thereof. The sheath material is composed of the following raw materials in parts by weight: 70-90 parts of SG-4 type polyvinyl chloride resin, 15-25 parts of polyetheretherketone, 8-12 parts of ABS, 10-15 parts of di-iso-decylphthalate, 5-10 parts of dibutyl maleate, 15-25 parts of fumed silica, 1-2 parts of a calcium zinc composite stabilizer, 2-3 parts of barium stearate, 8-12 parts of trixylenyl phosphate, 3-5 parts of palm wax, 10-15 parts of magnesium hydroxide, 5-10 parts of decabromodiphenyl ethane, 4-6 parts of zinc borate, 5-10 parts of powdered pumice, 10-15 parts of nano barium titanate, and 3-6 parts of a composite filler. The waterproof flame-retardant PVC cable sheath material and the preparation method thereof are provided, the sheath material overcomes the disadvantage of poor waterproof of conventional products; and with long-term use in a humid or soaking environment, the sheath material has the product performance which is basically not reduced, and is not deformed and not swollen, besides, has excellent flame retardant performance, excellent physical mechanical properties and excellent machining performance, and has wide application prospects.

Description

technical field [0001] The invention relates to a cable sheath material and a preparation method thereof, in particular to a water-resistant and flame-retardant PVC cable sheath material and a preparation method thereof. Background technique [0002] The cable sheath is an indispensable intermediate structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and isolating the copper wire from water, air and other media to avoid leakage. Polyvinyl chloride material is widely used in the cable sheath layer because of its excellent physical and mechanical properties, electrical properties, flexibility, low price, and excellent processing performance. However, with the expansion of cable applications, the performance requirements for PVC sheath materials continue to increase, among which the hydroelectric insulation performance of PVC has not been successfully resolved. Contents of the invention [0003] The object of the pres...
