Abstract

The invention discloses an insulating cable material for optical fiber cables and a preparation method thereof, which is made of the following raw materials in parts by weight: XS-3 type PVC resin 70-90, polytetrafluoroethylene 20-30, nylon-11 15-25 , polycarbonate 10‑15, C5 petroleum resin 12‑18, precipitated silica 20‑30, nano sepiolite 10‑15, zinc oxide 1‑2, magnesium oxide 2‑3, zinc stearate 1‑2 , Barium Stearate 1‑2, Epoxy Dioctyl Tetrahydrophthalate 8‑12, Tributyl Phosphate 5‑10, Glyceryl Monostearate 2‑3, Zinc Borate Hydrate 4‑8, Compound Filler 5‑10, antioxidant 1076 0.5‑1. The cable material of the present invention has good high and low temperature flexibility, excellent physical and mechanical properties such as creep resistance, wear resistance, oil resistance, tear resistance, and aging resistance, and has a good flame retardant effect. After the flame disappears, the flame can be extinguished quickly without delaying other Material, less smoke when burning, etc., meet the requirements for the use of insulating materials for optical fiber cable sheaths.

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...
