Cross-linked polyethylene insulated anti-interference shielding naval vessel cable and preparation method thereof

Abstract

The invention discloses a cross-linked polyethylene insulated anti-interference shielding naval vessel cable and a preparation method thereof, a shielding material is prepared in the process of preparing the anti-interference shielding naval vessel cable, the shielding material contains a large number of high-resistance metal objects, and the high resistivity enables electromagnetic waves to easily enter and rapidly attenuate; and the obtained cable can still keep high magnetic conductivity at high frequency. The graphene, the carbon nano tube and the copper have excellent conductivity, so that the shielding carrier has electrical loss and magnetic loss at the same time, impedance matching of electromagnetic absorption is achieved, the absorption frequency band is widened, the anti-interference performance is improved, oxygen-containing acid of phosphorus can be generated in the combustion process. Phosphorus oxyacid catalyzes a hydroxyl-containing compound to be dehydrated into carbon, then a coke layer is generated on the surface of the thermal insulation material, and the coke layer can isolate oxygen and heat to extinguish flame, so that the flame retardance of the cable is further improved.

Description

technical field

[0001] The invention belongs to the technical field of cable preparation, and in particular relates to a cross-linked polyethylene insulated anti-interference shielded naval cable and a preparation method thereof. Background technique

[0002] With the improvement of the automation level of ships and offshore platforms, a large number of electronic equipment and instruments need to transmit signals through various communication cables. Due to the harsh environment of ships, at present, many ships replace cables more frequently for safety reasons, which greatly While increasing the operating cost, it also restricts the execution of long-term offshore tasks, so the cable material is strengthened in the application.

[0003] The existing anti-jamming shielded ship cable has poor self-shielding effect during use, which will affect the communication effect, and its own poor flame retardancy will cause rapid burning when exposed to open flames. Contents of the in...
