Optical fiber cable-used insulated cable material and preparation method thereof

Abstract

The invention discloses an optical fiber cable-used insulated cable material and a preparation method thereof. The material is prepared by the following raw materials by weight: 70 to 90 of XS-3-type resin, 20 to 30 of PTFE, 15 to 25 of nylon-11, 10 to 15 of polycarbonate, 12 to 18 of C5 petroleum resin, 20 to 30 of precipitated white carbon black, 10 to 15 of nano sepiolite, 1 to 2 of zinc oxide, 2 to 3 of magnesium oxide, 1 to 2 of zinc stearate, 1 to 2 of barium stearate, 8 to 12 of di(2-Ethylhexyl)-4,5-epoxytetrahydrophthalate, 5 to 10 of tributyl phosphate, 2 to 3 of monostearin, 4 to 8 of hydrated zinc borate, 5 to 10 of composite filler, and 0.5 to 1 of an antioxidant 1076. The cable material is good in flexibility at high and low temperature and has excellent physical and mechanical performance of creeping resistance, wear resistance, oil resistance, tearing resistance, aging resistance and the like; the flame-retardant effects are good, and the fire tongue can be quickly extinguished after the flame disappears, other material is not burnt, the smoke amount generated in the case of burning is small, and the use demands of the insulated material of an optical fiber cable protection layer can be met.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to an insulating cable material for an optical fiber cable and a preparation method thereof. Background technique [0002] A fiber optic cable is a communication cable consisting of two or more glass or plastic optical fiber cores within a protective cladding covered by a plastic PVC outer sleeve. With the rapid development of optical fiber cables in my country, the requirements for mechanical strength, creep resistance, high and low temperature resistance, and flame retardancy of optical fiber cable outer insulation sheath materials are becoming more and more stringent. However, the existing PVC cable materials It can no longer meet the requirements of my country's optical fiber construction. Contents of the invention [0003] The object of the present invention is to provide an insulating cable material for optical fiber cables with excellent physical and mech...
