Embodiment Construction

[0010] A cold-resistant PVC sheathing material for cables, made of the following raw materials (kg): SG-4 type polyvinyl chloride 80, chlorosulfonated polyethylene 20, neoprene 15, epoxy tetrahydrophthalic acid Dioctyl Ester 12, Diisobutyl Nylonate 8, ACR5, Ethylene Bis Stearic Acid Amide 2, Dipropylene Glycol Dibenzoate 10, Antioxidant 2461, Decabromodiphenyl Ether 12, Polyphosphoric Acid Ammonium 6, dibasic lead phosphite 1, tribasic lead sulfate 1.5, barium stearate 2, epoxy soybean oil 6, titanium dioxide 4, acetylene carbon black 25, calcined loess 8, activated calcium carbonate 12, composite filler 5;

[0011] The preparation method of the composite filler is as follows: a. Take bentonite, barite, and monazite in a weight ratio of 5:4:3, then add 2% coal powder and 1.5% 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 beat to make a slurr...

Abstract

The invention discloses a cold-resistant PVC sheath material for a cable and a preparation method thereof. The sheath material comprises the following raw materials in parts by weight: 75-95 of SG-4 type polyvinyl chloride, 15-25 of chlorosulfonated polyethylene, 10-15 of chloroprene rubber, 10-15 of dioctyl epoxy tetrahydrophthalate, 5-10 of di-isobutyl adipate, 4-7 of ACR, 2-3 of N,N'-ethylene hisstearamide, 8-12 of dipropylene glycol dibenzoate, 1-1.5 of an antioxidant 246, 10-15 of decabromodiphenyl oxide, 5-10 of ammonium polyphosphate, 1-2 of dibasic lead phosphite, 1-2 of tribasic lead sulfate, 2-3 of barium stearate, 4-8 of epoxidized soybean oil, 3-6 of titanium dioxide, 20-30 of acetylene carbon black, 5-10 of calcined loess, 10-15 of active calcium carbonate, and 4-6 of a composite filler. The sheath material has high cold resistance, has the low temperature impacting brittleness temperature of up to -50 DEG C, also still maintains excellent tensile strength, impact resistance, abrasion resistance, aging resistance and the like under a low temperature condition, is durable in use, and has broad application prospects.

Description

technical field [0001] The invention relates to a cable sheath material and a preparation method thereof, in particular to a cold-resistant PVC sheath material for cables 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. However, the current PVC sheath has the disadvantage of poor cold resistance, and it is easy to be brittle and cracked under high cold conditions, thereby affecting the performance of the cable. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the object of the present invention is to provide a cold-resistant PVC sheathing material for cables and a preparation method thereof. The low-temperature impact embrittlement temperature of the sheathing material can reach -5...
