Ship safe harbor returning cable and manufacturing method thereof

Abstract

The invention discloses a ship safe harbor returning cable, which comprises an insulating wire core, the insulating wire core comprises a conductor and an insulating layer, the conductor is formed by twisting a plurality of metal-plated annealed copper wire monofilaments, and a copper wire gap is filled with a conductor sealant; a plurality of insulated wire cores and sealant filling strips are stranded to form a cable core, gaps between the insulated wire cores and the sealant filling strips are filled with soft melting type wire core sealant, and the cable core is sequentially wrapped by a first wrapping tape, an inner lining layer, an armor, a second wrapping tape and an outer sheath to form the whole cable. The insulating layer is made of high-temperature fire-resistant watertight insulating rubber and comprises the following raw material components in parts by weight: 20 parts of methyl vinyl silicone rubber 110-3-B; 20 parts of EPDM three-well EPT 4045M; 0.6 to 1 part of bis(tert-butylperoxy isopropyl) benzene (BIPB); 0.2 to 0.3 part of trimethylolpropane trimethacrylate (LS-3-80); 0.4 to 0.6 part of an amine aldehyde compound anti-aging agent XH-3; 0.2 to 0.4 part of 2-mercapto benzimidazole (MBI); 5-9 parts of gas phase method surface treatment white carbon black; 4-8 parts of low-temperature low-melting-point glass powder with the softening temperature of 400-700 DEG C; 4-8 parts of high-temperature low-melting-point glass powder with the softening temperature of 600-1100 DEG C; 0.5 to 1.5 parts of iron sesquioxide; 0.4 to 1 part of diphenyl silanediol; and 0.1 to 0.2 part of SI69-50.

Description

technical field [0001] The invention mainly relates to the technical field of cables, in particular to a cable for safe return of ships to port and a manufacturing method thereof. Background technique [0002] Based on the principle that "the ship itself is its best lifeboat", the International Maritime Organization (IMO) has paid more and more attention to the safety of ships. The International Convention for the Safety of Life at Sea (SOLAS) has proposed "Safe Return to Port" concept; IMO continues to reinforce this requirement. In December 2006, the IMO Maritime Safety Committee announced MSC.216(82) resolution, which added the content of safe return to port, which constituted the basis for the regulations of safe return to port; in May 2010, it approved MSC.1 / Circ. or Interim Explanatory Notes on System Capability Assessment after Flooding Accidents", clarifying the requirements for safe return to port and orderly evacuation; in May 2012, resolution MSC.325(90) was pass...

AI Technical Summary

Problems solved by technology

[0003] The requirements for the safe return of ships to the port put forward new requirements for the supporting cables to be used in this working condition, that is, to have both (1100°C, 3h) fire resistance and corresponding watertightness (including longitudinal watertightness and transverse watertightness), but currently In the industry, there are only cables that satisfy a single performance, and there is no cable that has both performances at the same time
