Problems solved by technology

[0002] The existing cable sheath materials are not suitable for marine cables, and their oil resistance, wear resistance and corrosion resistance are not ideal. In addition, toughness, wear resistance, cold resistance, water resistance, aging resistance, acid and alkali resistance and weather resistance Not great either, doesn't last long
In the prior art, it is also used as a sheath material for marine engineering cables, but it does not have the functions of anti-ultraviolet radiation and energy release, and is not suitable for extremely harsh occasions such as oil pollution and low-temperature environments, and cannot effectively resist oil pollution, seawater, etc. The cable can work safely and stably for a long time in harsh environments such as high salinity and high humidity
