Embodiment Construction

[0010] A sheath material for control signal cables, made of the following raw materials in weight (kg): 70 low-density polyethylene, 20 SG-3 polyvinyl chloride, 20 styrene-butadiene rubber, HIPS7, 10 nano-calcium carbonate, and nano-kaolin 10. Ultrafine mica powder 8, naphthenic oil 5, sulfur 2, accelerator M2, zinc oxide 2, stearic acid 3, phenolic resin 6, antioxidant 10102, tert-butyl peroxybenzoate 0.8, oxidized polyethylene wax 4. Rosin pentaerythritol ester 5, accelerator TMTD1, diisobutyl phthalate 8, dioctyl nylon acid 10, 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 4:4:3, then add 2% coal powder and 1.5% activated carbon by weight of bentonite, and mix them evenly 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 wit...

Abstract

The invention discloses a sheath material for a signal controlling cable and a preparation method thereof. The sheath material comprises the following raw materials in parts by weight: 65-75 parts of low density polyethylene, 20-30 parts of SG-3 type polyvinyl chloride, 15-25 parts of styrene butadiene rubber, 5-10 parts of HIPS, 10-15 parts of nano calcium carbonate, 8-12 parts of nano kaolin, 5-10 parts of an ultrafine mica powder, 3-6 parts of naphthenic oil, 2-3 parts of sulfur, 1-2 parts of an accelerant M, 1-2 parts of zinc oxide, 3-4 parts of stearic acid, 4-8 parts of phenolic resin, 2-3 parts of an anti-aging agent 1010, 0.5-1 part of tert-butyl peroxybenzoate, 3-5 parts of oxidized polyethylene wax, 4-6 parts of rosin pentaerythrityl ester, 1-2 parts of an accelerant TMTD, 5-10 parts of diisobutyl phthalate, 8-12 parts of dioctyl nylon acid ester, 3-6 parts of a composite filler. The sheath material has good high and low temperature resistance and high tensile strength, also has excellent abrasion resistance, acid and alkali resistance, oil resistance, ozone aging resistance, and ultraviolet radiation resistance, extends the service life of a sheath to a great extent, and widens the application scope.

Description

technical field [0001] The invention relates to a cable sheath material and a preparation method thereof, in particular to a sheath material for a control signal cable and a preparation method thereof. Background technique [0002] The cable jacket plays a vital role in protecting the internal components from damage to maintain their normal operation, so the jacket material must be able to resist sun and rain, ultraviolet radiation, ozone aging, chemical attack and withstand high temperature and severe cold And other harsh environmental conditions, while still ensuring normal work under accidental disasters. At present, domestic control signal cable sheaths usually use polyvinyl chloride or polyethylene as the sheath material. However, the above materials are not ideal in terms of heat resistance, cold resistance, and weather aging resistance, which greatly affects the service life of the sheath. Contents of the invention [0003] The purpose of the present invention is t...
