Abstract

The invention discloses a nuclear-powered ship cable high-flame-resistance low-smoke halogen-free sheath material, and a preparation method thereof. The nuclear-powered ship cable high-flame-resistance low-smoke halogen-free sheath material comprises, by weight, 30 to 50 parts of ethylene-acrylate copolymer, 10 to 30 parts of polyester elastomer, 10 to 30 parts of nylon elastomer, 10 to 30 parts of polyethylene, 5 to 20 parts of a compatilizer, 150 to 200 parts of a fire retardant, 10 to 30 parts of a flame retardant synergist, 5 to 15 parts of a radiation resistant auxiliary agent, 1 to 3 parts of an anti-oxidant, 0.5 to 2.5 parts of a processing auxiliary agent, and 0.5 to 2.5 parts of an auxiliary crosslinking agent.

Description

technical field [0001] The invention relates to the field of low-smoke, halogen-free, and flame-retardant cable materials, in particular to a high-flame-retardant, low-smoke, and halogen-free sheathing material for nuclear power ship cables and a preparation method thereof. Background technique [0002] With the rapid development of our country's naval weapons and equipment, the safe operation of ship cables is more and more important because it is directly related to improving the combat effectiveness of ships and personnel safety. [0003] With its advantages of high power and strong endurance, nuclear power is widely used in military ships such as nuclear submarines and nuclear powered aircraft carriers. As the main components of the nuclear power ship, the use environment of the cable is harsher than that of the conventional power ship. Power or vibration will cause poor contact at the connection, causing the cable at the connection to age easily. Such an installation ...
