AI Technical Summary
Existing marine communication cables have insufficient waterproof reliability in seawater immersion and salt spray environments. The water-blocking layer is prone to delamination and failure, the filler layer is prone to expansion and deformation, the flame-retardant layer has an imbalance between hydrophobicity and compatibility, the inner lining layer has poor low-temperature adaptability, and the outer sheath has insufficient salt spray resistance, resulting in signal transmission failures and structural damage.
The design employs a combination of polyethylene composite insulation layer, rubber composite water-blocking layer, modified filler layer, compatible flame-retardant layer, low-temperature toughening inner lining layer, and salt spray resistant outer sheath layer. Through premixing, co-extrusion coating, vacuum filling, and hot-pressing composite processes, a tight structure is formed, which improves the interlayer bonding strength and overall performance.
It effectively solves the problems of moisture intrusion, interlayer peeling, structural deformation, low-temperature brittleness and salt spray resistance, and improves the cable's waterproof, flame retardant, low-temperature resistance and salt spray resistance performance, making it suitable for harsh marine environments and extending its service life.
