AI Technical Summary

Technical Problem

Existing submarine cables are gradually unable to meet market demand in terms of voltage resistance, strength and low temperature resistance, especially in complex submarine environments.

Method used

Modified aerogel is combined with high-density polyethylene, styrene-maleic anhydride copolymer, 2,7-anthraquinone ethanesulfonic acid, modified polybutylene succinate and acetyl triethyl citrate and other materials. The performance of the material is enhanced by silane and thiol modified aerogels to form a submarine cable material with excellent lightweight, pressure resistance, corrosion resistance, flexibility and chemical stability.

Benefits of technology

It improves the service life of submarine cables in extreme environments, enhances mechanical strength and chemical stability, reduces the risk of seawater corrosion and fracture in low-temperature environments, and extends the service life of cables.

Abstract

The invention provides an aerogel-based submarine cable material as well as a preparation method and application thereof.The submarine cable material is prepared from the following raw materials in parts by weight: 10-20 parts of modified aerogel, 20-25 parts of high-density polyethylene, 6-10 parts of a styrene-maleic anhydride copolymer, 4-6 parts of 2, 7-anthraquinone ethanesulfonic acid and 5-7 parts of modified poly (butylene succinate), 2 to 4 parts of acetyl triethyl citrate; the modified aerogel is prepared from silane modified aerogel and sulfydryl modified aerogel in a mass ratio of 1: (1-3). By compounding the raw materials, the comprehensive performance of the cable material is comprehensively improved, so that the cable material has excellent light weight, pressure resistance, low temperature resistance, corrosion resistance, flexibility, aging resistance and chemical stability, has good environmental adaptability, prolongs the service life of a cable in an extreme seabed environment, and has good social use value.
