Problems solved by technology

At present, polyethylene materials are mostly used as halogen-free flame-retardant sheathing materials in the market. In order to ensure the flame-retardant effect, a large amount of flame-retardant materials are filled in the sheathing materials, which will greatly reduce the heat resistance and aging resistance of the sheathing materials, thereby limiting The operating environment and operating temperature

Embodiment Construction

[0010] A high-temperature-resistant sheath material for cables, made of the following raw materials (kg): high-density polyethylene 75, EPDM rubber 25, maleic anhydride grafted polyethylene 12, bisphenol A novolac epoxy Resin 8, toluene diphenyl phosphate 10, dioctyl maleate 6, bis-tert-butylperoxycumene 0.7, p-benzoquinone dioxime 2.5, triallyl isocyanurate 1.5, paraffin oil 4. Active zinc oxide 2, magnesium hydroxide 12, aluminum hydroxide 8, talc powder 5, fly ash 10, nano bauxite 8, dibutyltin dilaurate 2, antioxidant MB2, antioxidant TPPD1, 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 5:3:3, then add 2.5% 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 slurry with a concentration of 45%, added ...

Abstract

The invention discloses a high-temperature-resistant cable sheath material and a preparation method thereof. The sheath material comprises the following raw materials in parts by weight: 70-80 of high density polyethylene, 20-30 of ethylene-propylene-diene monomer, 10-15 of maleic anhydride grafted polyethylene, 5-10 of bisphenol A novolac epoxy resin, 8-12 of diphenyl tolyl phosphate, 4-8 of dioctyl maleate, 0.5-1 of di(tert-butylperoxyisopropyl)benzene, 2-3 of p-benzoquinone dioxime, 1-2 of triallyl isocyanurate, 3-5 of paraffin oil, 2-3 of active zinc oxide, 10-15 of magnesium hydroxide, 5-10 of aluminum hydroxide, 4-6 of talcum powder, 8-12 of fly ash, 5-10 of nano bauxite, 2-3 of dibutyltin dilaurate, 1-2 of an anti-aging agent MB, 1-2 of an anti-aging agent TPPD, and 4-6 of a composite filler. The sheath material prepared by the invention not only has good high temperature resistance and can be used in a 125 DEG C working environment for a long time, but also has good flame retardant effect, has the oxygen index of more than 35%, has non halogen and low smoke, and solves the problem of poor heat resistance of a high-flame-retardant sheath material.

Description

technical field [0001] The invention relates to a cable sheath material and a preparation method thereof, in particular to a high temperature resistant 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. At present, polyethylene materials are mostly used as halogen-free flame-retardant sheathing materials in the market. In order to ensure the flame-retardant effect, a large amount of flame-retardant materials are filled in the sheathing materials, which will greatly reduce the heat resistance and aging resistance of the sheathing materials, thereby limiting Its use environment and temperature. Contents of the invention [0003] The object of the present invention is to provide a high temperature re...
