Abstract

The invention discloses a self-repairing reinforcing material for an optical cable. The self-repairing reinforcing material comprises a base material and a resin layer on the surface of the base material. The resin layer comprises the following raw materials in parts by weight: 80-100 parts of epoxy resin, 10-20 parts of an amide oligomer, 30-40 parts of self-repairing polyurethane, and 1-2 partsof a catalyst, wherein the amide oligomer is obtained by reacting dimer acid with diethylenetriamine. The invention further discloses a preparation method of the self-repairing reinforcing material for the optical cable. According to the self-repairing reinforcing material and the preparation method, the substrate and the resin layer are compounded, the resin layer adopts the epoxy resin as a mainmaterial, the self-repairing polyurethane is combined to improve the toughness and the self-repairing property of the reinforcing material, and the addition of the amide oligomer and the catalyst promotes the self-repairing reaction of the polyurethane, and the self-repairing effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of optical cables and optical cable materials, in particular to a self-repairing reinforcing material for optical cables and a preparation method thereof. Background technique [0002] Since the beginning of the 21st century, the communication industry has developed rapidly, and optical cables have been widely used in various fields. In order to meet the requirements of different use environments, especially harsh environments, it is necessary to coat the cable core with materials of different structures. Among them, the fiber optic cable strengthening core is an indispensable key material in the construction and application process of the fiber optic cable. It provides support and protection for the fiber optic cable. There are two types of commonly used reinforcing materials, one is the strengthening core based on continuous glass fiber, and the other is Reinforcing core based on aramid fibers. The new re...
