Preparation method of high-strength lightweight buoyancy material

Abstract

The invention relates to a preparation method of a high-strength lightweight buoyancy material, and belongs to the technical field of buoyancy materials. According to the technical scheme, a microsphere material is coated with glass micro powder, then melting is carried out, and oscillating and drawing are carried out, so that uniformly loaded fine fibers are formed on the surfaces of the hollow microspheres. Through the fiber-like coating, due to the fact that glass micro beads are in a compact piling state, a micro bead-fiber material forms as a main supporting framework along with the increase of filling amount of the glass micro beads. Due to the fact that the strength of the micro bead-fiber material is strengthened through fiber filling, force borne by a part of the micro bead-fibermaterial is effectively released under the action of hydrostatic pressure and filling is carried out, and then an effective three-dimensional mesh-shaped interweaving structure is formed in the material, so that uniformity of internal pores and filling continuity are improved. Therefore, the performance of the material after filling is effectively improved, the lightweight buoyancy material has excellent mechanical and compressive strength, and mechanical property and compression resistance of the material are further improved.

Description

technical field [0001] The invention relates to a preparation method of a high-strength lightweight buoyancy material, belonging to the technical field of buoyancy materials. Background technique [0002] The level of technology research and development of deep-sea equipment determines the level of development and utilization of deep-sea resources in a country. At present, many countries have extensively carried out research and development of deep-sea equipment, research on shell materials with good compression resistance and buoyancy materials with light weight and high strength. These are the two hot spots in current deep-sea equipment research. Lightweight and high-strength buoyancy materials have high requirements on pressure resistance, structural stability and density. In recent years, researchers from various countries in the world have done a lot of research work on the research and technology development of lightweight buoyant materials. At present, some material...
