Abstract

The invention discloses a solid buoyancy material for abyss development equipment, which comprises the following components in parts by mass: 100 parts of matrix resin, 50-200 parts of curing agent, 0.1-5 parts of accelerator, 0.1-5 parts of polyol, 0.1~5 parts of carbon nanofibers and 50~200 parts of hollow glass beads. The preparation method of the solid buoyancy material is as follows: firstly weighing the material, surface-treating the carbon nanofibers, then mixing the matrix resin and the surface-treated carbon nanofibers uniformly, and ultrasonically dispersing to obtain a resin glue, then adding the curing agent, accelerator, polyol , Hollow glass microspheres and resin glue are mixed uniformly at low speed and vacuum defoamed and then injected into the mold; then the mold filled with the mixture is placed in the microwave equipment, microwave irradiation is carried out in sections, and then the blank is obtained by demoulding; finally The blank is heated to 120~160°C and kept for no more than 6 hours, and then naturally cooled to room temperature to obtain a solid buoyant material. The solid buoyancy material prepared by the microwave curing molding process can be used in the abyss area from 6,000 meters to 11,000 meters below the sea surface.

Description

technical field [0001] The invention relates to the field, in particular to a solid buoyancy material for abyss development equipment and a preparation method thereof. Background technique [0002] With the development of marine science and technology, my country's efforts in marine development are increasing year by year and expanding into the abyss. Various manned or unmanned abyss carrying and operating equipment play an important role. Solid buoyancy materials are usually installed outside the abyss development equipment to provide sufficient static buoyancy and withstand huge underwater pressure, and are an important part of the development of modern deep diving technology. The solid buoyancy material on the outer surface can play a certain protective role. Therefore, the development of solid buoyancy material for abyss development equipment has important practical significance and application value.
