Problems solved by technology

At present, ordinary cables are often used in deep sea equipment, but because ordinary cables cannot adapt to the high water pressure environment in deep sea, water leakage is prone to occur, and more seriously, seawater will enter the cable and corrode the cable, resulting in cable scrapping or even damage.

Abstract

The invention discloses a composite water-blocking glue and a composite cable, and relates to the technical field of marine cables, so as to improve the longitudinal water-blocking performance of the cable. The composite water-blocking adhesive includes A component and B component in a mass ratio of 1:1. Wherein, the composition of the A component is organosilicon modified epoxy resin, water-based fluorocarbon emulsion resin, silane waterproofing agent, coupling agent and auxiliary agent, and the rest is water, and the B component includes Portland cement and filler. The composite cable includes the composite water-blocking glue mentioned in the above technical solution. The composite water-blocking glue provided by the invention is used in cables of deep-sea equipment.

Description

technical field [0001] The invention relates to the technical field of marine cables, in particular to a composite water-blocking glue and a composite cable. Background technique [0002] Due to the special environment of the deep sea, the cables in the deep sea equipment have higher requirements. At present, ordinary cables are often used in deep-sea equipment, but because ordinary cables cannot adapt to the high water pressure environment in the deep sea, water leakage is prone to occur, and more seriously, seawater will enter the cable and corrode the cable, thereby causing the cable to be scrapped or even damaged. Connected deep sea devices. [0003] Therefore, there is an urgent need for a water-blocking glue that is suitable for deep-sea environments and can achieve a good longitudinal water-blocking effect. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a composite water-blocking glue and a composite cable, which are used in c...
