Problems solved by technology

It is difficult to process the cable with ordinary materials to meet the high standard requirements. The traditional cable insulation and sheath are made of polyolefin. Although the cover is soft, it has poor weather resistance, aging resistance and flame resistance. The above two types of materials cannot meet the requirements of special environments.

Embodiment 1

[0014] The present invention proposes a communication cable for ships, which includes two copper conductors covered with an insulating layer that are twisted together to form a core, and four cores that are twisted to form a cable core. The outside of the cable core is from the inside to the outside. Covered with a wrapping layer, a shielding layer, and a sheath layer in turn; the sheath layer is prepared by the following process: Weigh 100 parts of thermoplastic polyether polyurethane TPU and 8 parts of propylene-1-hexene copolymer by weight. Polar monomer graft, 5 parts of carbon black, 0.1 part of UV absorber UVA, 0.5 part of hindered amine UV stabilizer HALS, 0.1 part of antioxidant, 40 parts of halogen-free flame retardant, 0.1 part of metal soap lubricant, 4 parts of plasticizer, 0.8 part of bis[4-(1-methyl-1-phenylethyl)-2,6-diisopropylphenyl]carbodiimide, wherein the anti The oxygen agent is composed of 85wt% hindered phenolic antioxidant and 15wt% phosphite antioxidan...

Abstract

The invention discloses a communication cable for ships. A sheath layer comprises the following raw materials by weight: 100 parts of thermoplastic polyether urethane TPU, 8-10 parts of polar monomer graft of propylene-1-hexene copolymer, 1-5 parts of carbon black, 0.1-1.0 parts of ultraviolet absorber UVA, 0.05-0.5 parts of hindered amine light stabilizer HALS, 0.1-1.0 parts of antioxidant, 10-40 parts of halogen-free flame retardant, 0.1-1.0 parts of metal soap lubricant, 1-4 parts of plasticizer, and 0.8-1.35 parts of bis[4-(1-methyl-1-phenyl ethyl)-2,6-diisopropyl phenyl]carbodiimide, wherein the antioxidant is composed of 65-85wt% of hindered phenol antioxidant and 15-35wt% of phosphite antioxidant. The communication cable of the invention is resistant to oil, water, corrosion and abrasion, and is applicable to ships.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a communication cable for ships. Background technique [0002] The communication cables used in the ship environment need to meet the requirements of strong anti-interference ability, anti-corrosion, anti-salt spray, waterproof, oil resistance, wear resistance, anti-oxidation, high mechanical strength and electrical insulation, and also have a long service life and can be used in Highly reliable services can be guaranteed in complex environments. It is difficult to process the cable with ordinary materials to meet the high standard requirements. The traditional cable insulation and sheath are made of polyolefin. Although the cover is soft, it has poor weather resistance, aging resistance, and flame resistance. The above two types of materials cannot meet the requirements of special environments. Contents of the invention [0003] The technical problems in the basic background ...
