[0048] 3,5,4'-Tribromosalicylanilide 1.

[0049] The mixing process includes the following steps:

[0050] 1) Plasticizing neoprene and natural rubber in a double-roll mill at room temperature, passing the roll 3 times;

[0051] 2) After plasticizing, add 110 internal mixer. The total volume of the internal mixing chamber is 108L, the working volume is 81L, and the charging factor is about 60%. Using the reverse mixing method, rotating speed 25r / min, add the above mass fraction of carbon black, magnesium oxide, stearic acid, N-phenyl-B-naphthylamine, 2-mercaptobenzimidazole, petrolatum, etc. to the internal mixer. The curve tends to be flat and the mixing ends. Th...

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 deep-water tight cables and a preparation method thereof. Background technique [0002] The ocean is a treasured 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. The watertight connector is one of the key general supporting components for submersibles and other marine equipment, and is an indispensable configuration for completing deep-sea exploration, resource exploration and evaluation. Therefore, with the increasing development of marine research and marine development, watertight connector technology applied in the deep sea has been highly valued. The watertight connector was first introduced by Marsh&Marine in the United States in the early 1950s. Its structure is rubber molded. The development of deep sea watertight connectors ...
