Abstract
The invention discloses a marine high-frequency data transmission cable. The cable comprises eight copper wires and a cross framework. Each copper wire is coated with a semiconductor layer. Four ends of the cross framework are each provided with an end strip part. The semiconductor layer comprises following components in parts by weight: 100 parts of 1,3-butadiene, 55-58 parts of styrene, 28-30 parts of ethylene-vinyl acetate copolymer, 10-12 parts of ethylene-vinyl acetate copolymer grafted maleic anhydride copolymer, 8-10 parts of siloxane, 22-25 parts of fumed silica, 6-8 parts of copper powder, 1.2-1.6 parts of microcrystalline wax, 1.8-2 parts of titanium dioxide, 1-1.2 parts of 4,4'bis(alpha,alpha dimethyl benzyl)diphenylamine, 0.6-0.8 part of dicumyl peroxide, 2.2-2.5 parts of triallyl cyanurate, and 3.2-3.5 parts of dilauryl thiodipropionate. The marine high-frequency data transmission cable improves reflection and absorption of high-frequency electromagnetic waves, alleviates cross talk and signal attenuation, expands the bandwidth of absorption frequency and improves the stability of product performance.
