Abstract

The invention discloses an anti-aging cable outer protective layer for a ship and a preparation method of the anti-aging cable outer protective layer. The preparation method comprises the following steps: mixing bentonite, succinic anhydride, fatty alcohol, organic acid and water, centrifuging, dehydrating, and spray-drying to obtain a filler M; conducting primary thermal treatment and secondary thermal treatment on the filler M to obtain a modified filler M; mixing the modified filler M, neoprene, an alumina fiber, polyvinylidene fluoride, dimethylformamide, pine tar, carbon black, zinc oxideand barium stearate, internally mixing to obtain a mixed rubber; adding the mixed rubber into a vulcanizing machine, extruding, vulcanizing, and forming by hot-pressing to obtain the anti-aging cableouter protective layer for the ship. The anti-aging cable outer protective layer for the ship solves the following problems: the majority of the outer protective layer of an electric wire and a cableis adiabatic, then the dissipation of heat in the inner part of the electric wire and the cable is impeded on a certain degree while the cable outer protective layer provides the insulating property,the gathering of the heat accelerates the aging speed of the protective layer, and the service lives of the electric wire and the cable are shortened.

Description

Technical field [0001] The invention relates to the field of cables, in particular to an anti-aging cable outer sheath for ships and a preparation method thereof. Background technique [0002] Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and so on. They are composed of single or multiple strands of wires and insulating layers, which are used to connect circuits and electrical appliances. The outer sheath of wire and cable is mostly thermal insulation, which makes the outer sheath of the cable not only provide insulation performance, but also hinders the internal heat loss of the wire and cable to a certain extent. The accumulation of heat will accelerate the aging speed of the sheath and shorten the wire. The life of the cable. [0003] Therefore, it is an urgent problem to be solved by the prese...
