Abstract

The invention belongs to the technical field of submarine cables, and in particular relates to a submarine cable filled rigid profile and a preparation method thereof. A submarine cable filled rigid profile, in parts by weight, the raw materials include: 40-80 parts of modified recycled tire pellets, 20-50 parts of matrix resin, 0.1-0.5 parts of reinforcing agent, and 0.2- parts of stabilizer 1 part, 0.1-0.5 part of coupling agent; by selecting polyacrylamide-graphene oxide to modify the recycled tire particles and turning waste into treasure, the prepared filling type surface is smooth and cabling round, and graphene oxide adds energy. Enhances flexibility and cold resistance.

Description

technical field [0001] The invention belongs to the technical field of submarine cables, and in particular relates to a submarine cable filled rigid profile and a preparation method thereof. Background technique [0002] With the development of offshore wind power and the national economy, the demand for submarine cables is also increasing, and the reliability and environmental protection requirements for their work are also getting higher and higher. [0003] Existing submarine cables are generally filled with polypropylene mesh tear ropes for voltage levels of 35kV and below. For voltage levels above 35kV, due to the large outer diameter of the cable core and the large gap after cabling, it is difficult for polypropylene mesh tear ropes to ensure submarine cables. Roundness, so the voltage level above 35kV is mostly formed and filled with strip structure. Scrap tires can be used to process filler profiles for submarine cables, but the filler profiles processed directly fr...
