Abstract

The invention discloses a special flexing-resistant material for a protecting sleeve pipe for a communication cable and a preparation method of the special flexing-resistant material. The special flexing-resistant material is prepared from the following raw materials in parts by weight: 49 to 73 parts of polyethylene glycol terephthalate, 32 to 54 parts of alpha-methyl styrene-acrylonitrile-styrene terpolymer, 17 to 23 parts of nano-sized halloysite, 2 to 4 parts of calcium laurate, 14 to 19 parts of tri-isodecyl trimellitate, 2 to 3 parts of beta-diketone, 23 to 37 parts of thermoplastic polyurethane elastomer, 3 to 4 parts of stannous stearate, 14 to 21 parts of activated clay, 12 to 15 parts of colloidal antimony pentoxide, 9 to 17 parts of dipropylene glycol dibenzoate, 10 to 15 parts of alundum powder, 2 to 3 parts of N, N-p-phenylenediamine (2-hydroxy) dibenzyl tetraethyl phosphate, 4 to 7 parts of aluminum chlorohydrate, 2 to 3 parts of zinc benzoate, 3 to 5 parts of dechlorane plus, 1 to 2 parts of 2, 2`-methylenebis(6-tert-butyl-4-methylphenol), and 4 to 6 parts of adjuvant. The material is high in flexural strength, high in flexibility, and wide in applicable scope.

Description

Technical field [0001] The invention relates to a special material for a flexure-resistant communication cable sheath and a preparation method thereof, and belongs to the field of optical cable sheath materials. Background technique [0002] Communication optical cable is composed of a cable core and an outer sheath composed of several (core) optical fibers (generally from a few cores to several thousand cores). Its transmission capacity is much larger; attenuation is small; transmission distance is long; volume is small; weight Light; no electromagnetic interference; low cost. It is currently the most promising communication transmission medium. It is widely used for signal transmission in various sectors such as telecommunications, electric power, and broadcasting, and will gradually become the main body of the future communication network. Due to the limitation of the laying or use environment, the communication optical cable needs to be protected by an outer protective layer,...
