Abstract

The invention discloses a high-speed network data transmission cable for maritime affairs. The cable comprises eight copper leads and a cross framework, wherein the copper leads are wrapped with semiconductor layers; four end strip parts are arranged at the four tail ends of the cross framework respectively; and each semiconductor layer comprises the 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 parts of dicumyl peroxide, 2.2-2.5 parts of triallyl cyanurate, and 3.2-3.5 parts of dilauryl thiodipropionate. The cable improves reflection and absorption of a high-frequency electromagnetic wave, improves crosstalk and signal attenuation, expands the bandwidth of absorption frequency, and improves the stability of product performance.
