Technical Field

Background
Since the 21 st century, various countries in the world have been exploring and exploiting mineral resources such as oil and gas products in the marine field on a large scale to meet the increasing energy demand. In the face of wide ocean resources, particularly in the deep sea field, compared with land resources, the deep sea field has more resources. Meanwhile, the deep sea field is also an important field of national defense construction. In the process, the solid buoyancy material is used as a high-performance composite material with low density, high strength, low water absorption and high buoyancy, is an essential basic material for modern marine oil, natural gas and deep diving technology, can provide buoyancy for a platform device on the water surface, provides heat preservation and buoyancy for underwater pipelines, provides necessary buoyancy for deep diving equipment, and plays an important role in improving the effective load of a submersible vehicle, reducing the external dimension of the submersible vehicle and improving the underwater motion performance of the submersible vehicle. Therefore, the high-strength solid buoyancy material is widely applied to the marine field in both military and civil fields.
When the solid buoyancy material is applied to the deep sea field, the requirements on the buoyancy material not only have low density and high strength, but also have certain requirements on the vibration damping effect of the buoyancy material, at present, the research on the water damping characteristic of facilities and equipment for deep sea at home and abroad is less, and no clear and general solution exists. For the solid buoyancy material, the impact force applied during deep sea operation greatly affects the use efficiency of the buoyancy material, and the working tolerance of the buoyancy material is affected. Since the replacement of the buoyant material is a time-consuming, labor-consuming and expensive task in the face of the complex working environment in deep sea, the long durability of the solid buoyant material is one of the requirements for deep sea work. At present, improving the anti-damping property of the deep sea solid buoyancy material to absorb shock is one of the research subjects which cannot be ignored in the development of deep sea exploration.
The elastic materials such as rubber not only have the excellent characteristics of low density, softness, heat insulation, sound insulation and the like, but also have great guiding significance for the long-term use of the solid buoyancy material in the deep sea field due to the specific mechanical vibration absorption and impact resistance.
The invention aims to combine elastic materials such as rubber and the like with solid buoyancy materials, and improve the good shock resistance and shock absorption characteristics of the solid buoyancy materials when the solid buoyancy materials are applied in the deep sea field.
