Abstract

The invention discloses a deep-sea solid buoyancy material, which belongs to the technical field of polymer materials. The deep-sea solid buoyancy material of the present invention uses polydicyclopentadiene resin as the matrix resin. The resin has low average density, moderate viscosity and good fluidity. Compared with traditional resins, it can support more microbeads and microspheres, and further Reduce the density of the material. After the components of each specific ratio are coordinated with each other, the final prepared buoyant material has a compact structure and low water absorption, and has the characteristics of low density and high strength, and is suitable for sea area operations at a depth of 6000-11000m. The present invention also provides a preparation method of the deep-sea solid buoyancy material. The preparation method has simple operation steps and is environmentally friendly, and can realize industrialized large-scale production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a deep-sea solid buoyancy material and a preparation method thereof. Background technique [0002] Since the beginning of the 21st century, with the advancement of the global deep-sea strategy and the continuous development of deep-sea development technologies, and more and more deep-sea instruments and equipment have been put into use, people's demand for deep-sea buoyancy materials is increasing. Since the working environment of deep-sea instruments and equipment is usually extremely high in hydrostatic pressure, deep-sea buoyancy materials need to be used for the materials of deep-sea instruments and equipment to provide net buoyancy, so as to ensure the normal operation and safety of deep-sea instruments and equipment in the working environment of extremely high hydrostatic pressure. Therefore, the density, hydrostatic pressure resistance, water absorption and other...
