Embodiment Construction

[0014] A high ductility flame retardant cable sheath material, made of the following raw materials in weight (kg): acrylate rubber 70, polyurethane rubber 30, EVA10, EVA-g-MAH7, basic sodium aluminum carbonate 6, ammonium polyphosphate 8. Zinc borate 10, ammonium molybdate 4, carbon black N55018, basic magnesium carbonate 4, zinc stearate 2, bis(γ-triethoxysilylpropyl) tetrasulfide 2, anti-scorch agent CTP1 , polyethylene wax 5, dicumyl peroxide 0.6, triallyl isocyanurate 2, nano potassium feldspar 15, potassium titanate whisker 8, composite filler 4;

[0015] The preparation method of the composite filler is as follows: a. Weigh kaolin, diatomite, and dolomite in a weight ratio of 5:6:3, pulverize, mix evenly, wet ball-milling for 22 hours, then dry at 115° C., and then heat at 570 calcined at ℃ for 1 hour, cooled to room temperature, added an appropriate amount of water to make a slurry with a concentration of 45%, then added a 12% concentration of hydrochloric acid solution...

Abstract

The invention discloses a flame retardant cable sheath material with high malleability and a preparation method. The cable sheath material is prepared from the following raw materials, by weight, 60-80 parts of acrylate rubber, 20-30 parts of polyurethane rubber, 10-15 parts of EVA, 5-10 parts of EVA-g-MAH, 4-8 parts of basic sodium aluminum carbonate, 5-10 parts of ammonium polyphosphate, 8-12 parts of zinc borate, 3-6 parts of ammonium molybdate, 15-20 parts of carbon black N550, 3-5 parts of salt basic magnesium carbonate, 2-3 parts of zinc stearate, 1.5-2.5 parts of bis[3-(triethoxysilyl)propyl]tetrasulfide, 1-2 parts of anti-scorching agent CTP, 4-6 parts of polyethylene wax, 0.4-0.8 part of dicumyl peroxide, 2-3 parts of triallyl isocyanurate, 10-15 parts of nano potash feldspar, 5-10 parts of potassium titanate whiskers and 3-6 parts of composite filling materials. The sheath material has high malleability, high elasticity, good flexibility, high breaking elongation and tensile strength, good flame retardant effects, and has incombustibility and self-extinguishing property. The generated smoke is little during burning. No harmful gases are generated. The sheath material is durable, safe and environmentally friendly, and has wide application prospects.

Description

technical field [0001] The invention relates to a cable sheathing material and a preparation method thereof, in particular to a high ductility flame-retardant cable sheathing 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's power supply, and isolating the copper wire from water, air and other media to avoid leakage. In order to ensure that the cable sheath has sufficient strength, a large amount of inorganic fillers are added to the existing cable sheath material, but this leads to the disadvantages of poor elasticity and poor ductility of the sheath material, and cannot meet the increasing market demand. Contents of the invention [0003] The purpose of the present invention is to provide a high ductility flame retardant cable sheath material and a preparation method thereof in view of the ...
