Description

technical field [0001] The invention relates to the technical field of cable sealants, in particular to a sealant for underwater algae measuring cables and a preparation method thereof. Background technique [0002] The measurement of underwater algae is one of the important fields in deep sea research. Underwater measurement is inseparable from the use of watertight cables, which have strict requirements on the waterproof and sealing performance of cable materials. Sealants are often used to fill between the sealing layer and the outer sheath, the insulating layer and the sealing layer, and the shielding layer and the insulating layer, which play an important role in adhesion, and the waterproof performance of the sealant often determines the overall performance of the cable Waterproof sealing effect. At present, most of the ordinary cable sealants used in underwater measurement cannot fully meet the requirements of deep water operation environment and high waterproof perf...
