Abstract

The invention discloses a deep sea solid buoyancy material, and belongs to the technical field of high polymer materials. According to the deep sea solid buoyancy material, polydicyclopentadiene resinserves as matrix resin; the resin is low in average density, moderate in viscosity and good in fluidity; compared with traditional resin, the resin can load more microspheres and microspheres, and further reduce the density of the material. After the components in the specific proportion are mutually cooperated and matched, the finally prepared buoyancy material is compact in structure and low inwater absorption rate, has the characteristics of low density and high strength, and is suitable for sea area operation at the depth of 6000-11000m. The invention further provides a preparation method of the deep sea solid buoyancy material. The preparation method is simple in operation step and environmentally friendly, and canachieve industrial 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 technology, and more and more deep-sea instruments and equipment have been put into use, people's demand for deep-sea buoyancy materials is increasing. Due to the high hydrostatic pressure in the working environment of deep-sea instruments and equipment, the materials of deep-sea instruments and equipment need to use deep-sea buoyancy materials to provide net buoyancy, so as to ensure the normal operation and safety of deep-sea instruments and equipment in the extremely high hydrostatic pressure working environment Therefore, the density, hydrostatic pressure resistance, and water absorption of deep-sea buoyancy materials dire...
