Abstract

The invention discloses a rubber material for a full-sea-depth watertight cable and a preparation method. The rubber material is prepared from raw materials comprising the following ingredients in parts by weight: 100 parts of chloroprene rubber and natural rubber, 10-18 parts of vulcanizing system, 5-15 parts of plasticizer, 1-5 parts of antiaging system, 60-100 parts of filling system, 1-5 partsof antimicrobial agent and 0-8 parts of silane coupler, wherein a weight ratio of the chloroprene rubber to the natural rubber is (90 to 70): (10 to 30). The preparation method comprises the steps ofmilling the ingredients according to dosage, and carrying out extruding and vulcanizing, thereby preparing the rubber material for the full-sea-depth watertight cable. The material disclosed by the invention can pass watertight experiments of 1,000m, 3,000m, 7,000m and 10,000m, can bear experiments under the circulating pressure of 115MPa for 10 times and meets the requirements of coating materials for watertight cables on use in marine environments of high water depth (10,000m).

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber material for a full-sea deep water tight cable and a preparation method. Background technique [0002] The ocean is a treasure land for resource storage and national security, and the rational development of marine resources has gradually become one of the important strategic measures of various countries. Watertight connector is one of the key general supporting devices for submersibles and other marine equipment, and is an indispensable configuration for deep-sea exploration, resource survey and evaluation. Therefore, with the increasing development of marine research and marine development, the watertight connector technology applied to the deep sea has been highly valued. The watertight connector was first introduced by the American Marsh & Marine company in the early 1950s. Its structure is rubber molding. The development of deep sea water tight connectors in my cou...
