Abstract

The invention discloses a deep-sea cable water-blocking enhanced buffer strip and a preparation method thereof. The buffer strip is prepared from the following components in parts by weight: 60-80 parts of rubber, 20-30 parts of epoxy resin, 10-15 parts of tackifying resin, 5-10 parts of asphalt, 30-40 parts of filler, 20-30 parts of reinforced fibers, 2-5 parts of a vulcanizing agent, 1-3 parts of a vulcanization accelerator, 0.5-1.5 parts of an antiaging agent, 10-15 parts of processing oil and 3-5 parts of capsaicin. The preparation method is simple and convenient, is easy to implement, and has stable technical performance; the product is prepared by using a rubber material as a matrix through a reasonable formula design, has an excellent longitudinal waterproofing effect, and can be used for preventing the service life of cables from being influenced due to permeation of moisture or vapor. The deep-sea cable water-blocking enhanced buffer strip has an excellent comprehensive performance, has a super strong waterproofing and protecting effect for cables, and has a wide market prospect.

Description

technical field [0001] The invention relates to the field of submarine cables, in particular to a water-blocking reinforced buffer zone for deep-sea cables and a preparation method thereof. Background technique [0002] With the development of science and technology, the longitudinal water-blocking materials for submarine cables are constantly being updated and improved. At present, there are two main categories: water-blocking powder and water-blocking yarn. The two types of materials are different in technology, but both can achieve the purpose of moisture resistance and water resistance. Among them, the process of adding water-blocking powder is complicated, and it is difficult to ensure its uniform distribution, so water-blocking yarn is mostly used. The water-blocking yarn is usually wound between the twisted layers of metal wires at a certain pitch, and then through the pressing process, the water-blocking yarn is intermittently embedded in the gaps between the metal ...
