Abstract
The invention discloses a sealant formula specially used for watertight-typed cables and a preparation method thereof. The sealant comprises following components, by weight, 90-100 parts of neoprene, 50-60 parts of coumarone resin, 3-5 parts of zinc oxide, 5-8 parts of light-weight magnesium oxide, 0.5-0.8 parts of ethylene thiourea, 0.6-1 part of dihydroxylpolydimethylsiloxane, 3-4 parts of calcium stearate, 0.8-1 part of a 2,2,4-trimethyl-1,2-dihydrogenated quinoline polymer, 2-3 parts of fused magnesite, 1-2 parts of chlorhexidine, 2-4 parts of conch shell powder, 1-2 parts of silicon carbide, 10-15 of high-wear-resistant carbon black, 2-3 parts of perluorooctyl acrylate, 0.4-1 part of 8-hydroxylquinoline and 120-130 parts of calcium carbonate. The sealant is good in waterproof performance, is strong in adhesive force, is east to coat, is quite strong in the adhesive force and stability among each layer of the cable, can effectively prevent dislocation and movement in each layer of the cable under a high water pressure and can ensure a safety performance.
Description
technical field [0001] The patent of the present invention relates to a material formula and a preparation method thereof. Specifically, it relates to a special sealing glue formula for watertight cables and a preparation method thereof. Background technique [0002] Longitudinal watertight cables are required for the electrical connection between the sealed chamber and the outside of underwater ships such as submarines. In addition to meeting the longitudinal watertight performance under high water pressure (6-7MPa), this cable should also meet the requirements of normal pressure (0.3-0.5MPa). ) under the air tightness test requirements. This requires not only that all gaps in the cable cross-section be filled, but also that between layers of the cable (between metal materials and metal materials, between metal materials and non-metal materials, between non-metal materials and non-metal materials) It has strong adhesion to prevent dislocation and movement of each layer of...
