Abstract

The invention relates to the field of polymer materials, in particular to a cable sheath material resistant to seawater corrosion. The cable sheath material resistant to seawater corrosion is composedof the following raw materials: in parts by weight, 30-50 parts of modified polytetrafluoroethylene, 8-15 parts of aluminum bronze, 45-70 parts of nitrile rubber, 3-9 parts of ceramsite, 12-18 partsof glass fiber, 15-22 parts of phenolic resin, 5-11 parts of silica sol, 10-18 parts of crosslinked polyethylene, 2-6 parts of alumina ceramic powder, 0.3-1.7 parts of potassium titanate whisker, 11-17 parts of silicone, 1-6 parts of epoxidized soybean oil and 1-8 parts of a silane coupling agent. The cable sheath material resistant to seawater corrosion has reasonable component ratios, excellentchemical stability, excellent corrosion resistance, excellent anti-aging performance, high yield, high hardness, good wear resistance and long service life.

Description

Technical field [0001] The invention relates to the field of polymer materials, in particular to a seawater corrosion-resistant cable sheath material. Background technique [0002] The ocean can provide mankind with material resources, space resources and energy for survival and development. my country is a large maritime country with a coastline of more than 18,000 kilometers, more than 6,500 coastal islands, and a maritime area under its jurisdiction of more than 3 million square kilometers. my country has abundant marine resources and a thriving marine industry, but the marine environment is very harsh and highly corrosive. Therefore, marine corrosion and protection are issues that urgently need to be resolved in my country’s economic development. [0003] Submarine cables are cables wrapped with insulating materials and laid on the seabed for telecommunications transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Submarin...
