Abstract

The invention provides anti-aging cable sheath for electrical equipment, and a preparation method of the anti-aging cable sheath. The anti-aging cable sheath is prepared from the following components:ethylene propylene diene monomer (EPDM) rubber, nitrile rubber, dibutyl maleate, composite filler, modified carbon nanotubes, modified alumina, calcium oxide, sodium stearate, talc powder, polyethylene glycol, paraffin, sucrose stearate, an anti-aging agent, a flame retardant and an ultraviolet light absorber. The cable sheath prepared by the method is excellent in aging resistance, creep resistance, heat resistance, electrical insulating property, dimensional stability, mechanical strength and the like, and is low in price of the components and simple in preparation method, thus being suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of cable sheath materials, and in particular relates to an anti-aging cable sheath used for power equipment and a preparation method thereof. Background technique [0002] Cable is a general term for items such as optical cables and cables. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, power transmission, etc. It is a common and indispensable thing in daily life. [0003] The cable sheath is a structural part that protects the insulation layer of the wire and cable from environmental factors. The main function of the cable sheath is to improve the mechanical strength of the wire and cable, chemical corrosion resistance, moisture resistance, water immersion, and the ability to prevent the cable from burning. Cable sheaths include rubber, plastic, nylon and other varieties, all of which have their own excellent characteristics. For examp...
