Abstract

The invention discloses a wear-resistant communication optical cable jacket pipe special material and a preparation method thereof. The special material is prepared from the following raw materials in parts by weight: 36-48 parts of ultra-high molecular weight polyethylene, 21-33 parts of polyformaldehyde, 10-15 parts of tantalum diselenide, 7-13 parts of fused alumina zirconia powder, 4-8 parts of vaseline, 10-15 parts of Songhua stone powder, 4-6 parts of perfluoro-polyether, 3-5 parts of lanthanum fluoride, 6-9 parts of chlorinated paraffin, 14-18 parts of acetyl tributyl citrate, 15-20 parts of high-abrasion-resistance carbon black N660, 4-8 parts of zinc oxide whisker, 17-26 parts of butadiene rubber, 2-3 parts of dibutyl thiourea, 3-6 parts of basic lead silicate, 3-5 parts of 2-phenylindole, 4-6 parts of oxidized polyethylene wax, 1-2 parts of thiodipropionic acid octadecyl dodecyl ester, 4-8 parts of cresyl diphenyl phosphate and 2.5-4.5 parts of auxiliary agent. The jacket pipe special material has strong wear resistance, high mechanical strength and good fatigue resistance and aging resistance, and can prolong the service life of optical cables.

Description

technical field [0001] The invention relates to a special material for an abrasion-resistant communication optical cable sheath tube and a preparation method thereof, and belongs to the field of optical cable sheath materials. Background technique [0002] The communication optical cable is composed of a cable core and an outer sheath composed of several (core) optical fibers (usually from a few cores to several thousand cores). Light; no electromagnetic interference; low cost, it is the most promising communication transmission medium at present, widely used in signal transmission in telecommunications, electric power, broadcasting and other departments, and will gradually become the main body of future communication networks. Due to the limitations of the laying or use environment, the communication optical cable needs to be protected by an outer protective layer, which is usually called a "sheath". At present, the materials used for the communication optical cable sheath...
