Abstract

The invention discloses a solid buoyancy material for abyss development equipment. The solid buoyancy material comprises the following components in parts by mass: 100 parts of matrix resin, 50-200 parts of a curing agent, 0.1-5 parts of a promoter, 0.1-5 parts of polyols, 0.1-5 parts of nanocarbon fiber and 50-200 parts of hollow glass microbeads. A preparation method of the solid buoyancy material includes the steps that firstly, weighing is conducted, surface treatment is conducted on the nanocarbon fiber, then the matrix resin and the nanocarbon fiber subjected to surface treatment are evenly mixed and subjected to ultrasonic dispersion to obtain a resin glue solution, and then, the curing agent, the promoter, the polyols, the hollow glass microbeads and the resin glue solution are evenly mixed at the low speed, subjected to vacuum defoaming, and then injected into a mold; then the mold with an injected mixture is placed in microwave equipment, microwave radiation is carried out instages, and then demolding is conducted to obtain a billet; and finally, the billet is heated to 120-160 DEG C, heat preservation is conducted for not more than 6 h, natural cooling is conducted to the room temperature, and thus the solid buoyancy material is obtained. The solid buoyancy material prepared through a microwave curing forming process can be used in an abyss area of 6,000 meters to 11,000 meters below the surface of the sea.

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 to the abyss area. Various manned or unmanned abyssal vehicles and operating equipment play an important role. Solid buoyancy materials are usually installed on the outside of the abyss development equipment to provide sufficient static buoyancy and withstand the huge underwater pressure. It is 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.
