Abstract

The invention discloses a deep sea cable sheath material. The deep sea cable sheath material is characterized by containing the following raw materials in parts by weight: 65-72 parts of high densitypolyethylene, 16-22 parts of brominated polystyrene, 6-12 parts of basalt fibers, 5-8 parts of crocidolite, 3-6 parts of carbon fibers, 1.2-2.6 parts of acrylate resin, 0.8-1.5 parts of a protecting agent, 0.6-0.9 part of an antioxidant, 2-4.5 parts of polycarbonate, 2.2-3.2 parts of a cold-resistant plasticizer, 0.8-2.6 parts of an accelerant, 6-8.5 parts of mica powder, 0.6-1.2 parts of magnesium hydroxide, 0.3-0.6 part of benzoyl peroxide and 0.8-1.4 parts of tert-butyl peroxy-diisopropylbenzene. The deep sea cable sheath material is capable of effectively improving the damage resistance ofan outer sheath layer of a submarine cable and preventing biting of marine animals and is safe and environment-friendly.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a cable sheathing material suitable for deep sea. Background technique [0002] Submarine power cables are the cables with the highest requirements on cable performance. They not only need to meet the needs of high-strength pulling and wear resistance during laying, but also need to be able to resist high-pressure and high-corrosion environments on the seabed. It is necessary to prevent the biting of marine organisms, and long-term immersion in the seabed must not emit harmful substances to pollute the seawater and affect the seawater environment. [0003] At present, a large amount of energy mining requires electricity and electric communication, and the transmission of clean energy at sea will also use submarine cables in large numbers. The outer sheath layer is located on the outermost layer of the submarine cable, and plays a basic protective role such as waterproof, wear-resistant, an...
