Problems solved by technology

Because ships, especially ships on long-term patrol at sea, have long continuous working hours, regular maintenance is difficult, and cables will generate a lot of heat during long-term continuous work, which is prone to heat damage to cable sheaths, and if The flame retardant performance of the cable sheath is poor, it is easy to cause a fire on the cable line, which seriously threatens the service life of the ship and the safety of the crew

Abstract

The invention discloses a flame-retardant cable sheath for vessels and a preparation method thereof. The preparation method comprises the following steps: (1) kneading nano-phenyl silicone resin, polycaprolactam, ethylene-vinyl alcohol, high styrene rubber, ethyl acetate, glycerol and turpentine oil for the first time to obtain a mixture M1; (2) adding active alumina, silicon-barium, wear-resistant carbon black, kaolin, mica powder, boron fibers, citrate and a vulcanizing accelerator PDM into the mixture M1, and kneading for the second time to obtain a mixture M2; and (3) extruding and granulating the mixture M2, and processing to obtain the flame-retardant cable sheath for vessels. The preparation method is simple in process, and the flame-retardant cable sheath for vessels has excellent flame retardant performance and aging resistance to ensure long-time safe operation of vessels.

Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to a flame-retardant cable sheath for ships and a preparation method thereof. Background technique [0002] Generally speaking, a cable is made of one or more mutually insulated conductors and an outer insulating layer, which transmits power or information from one place to another. With the rapid development of the economy, more and more places need cables to transmit power or other information, so there are stricter requirements for the manufacture of cables. The sheath of the cable is an indispensable structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and insulating the cable core from water, air and other media to avoid leakage. [0003] In recent years, with the continuous strengthening of my country's marine development, fixed and non-fixed cables used to supply power to marine detection equipment, offshore floating...
