Example Embodiment

[0025] In parts by weight, respectively weigh 30-50 parts of sodium silicate, 5-12 parts of 300-400 mesh alumina powder, 10-20 parts of 200-300 mesh waste glass powder, 1-5 parts of urea, 0.2-0.4 The mass fraction is 5% ferric chloride aqueous solution, 0.1~0.3 parts platinum catalyst, sodium silicate, 300~400 mesh alumina powder, 200~300 mesh waste glass powder and urea are mixed, and the stirring speed is 300~500r / min. Magnetic stirring at room temperature for 1~2h, the mixture is obtained. Add platinum catalyst and 5% ferric chloride aqueous solution with mass fraction to the mixture successively, and continue stirring for 1~2 days to obtain the precursor. Dry and granulate in the form of droplets to obtain the green body. Place the green body in an oven, heat it up at 2℃ / min to 50~60℃, keep it for 6~8h, and then heat it up at 12℃ / min to 80~90℃ After keeping the temperature for 2~4h, the semi-finished product is obtained. The semi-finished product is placed in a quartz tube...

Abstract

The invention relates to a preparation method of a high-performance solid buoyancy material and belongs to the technical field of materials. Iron chloride is mixed in sodium silicate for crosslinkingforming and pyrolysis, pores formed in sodium silicate during pyrolysis and iron particles formed in the pores are taken as catalysts, nanofiber is grown in situ in a hollow glass microsphere matrix,the root part of the fiber is embedded in a matrix, the head extends out of the matrix, the fiber is closely and seamlessly combined with the matrix, the product is taken as filler, the high-performance solid buoyancy material is prepared, the fiber can slide in a local range of the matrix when the material is impacted by external force and broken, a toughening function is produced on the hollow glass microsphere matrix, and the prepared high-performance solid buoyancy material has good impact resistance. The high-performance solid buoyancy material is prepared with a vacuum impregnation method, equipment is simple, conditions are easy to control, the obtained high-performance solid buoyancy material has uniform quality, and hollow glass microspheres are high in filling rate and have goodthermal resistance.

Description

technical field [0001] The invention relates to a preparation method of a high-performance solid buoyancy material, belonging to the technical field of materials. Background technique [0002] The solid buoyancy material technology organically combines the low-density and high-strength properties of the material, making it incomparably superior in the field of ocean development technology. Deep diving technology is an important part of national defense security and marine resource development technology. [0003] The development and utilization of marine resources, especially deep-sea resources, occupies an important position in the development strategies of all developed countries. Deep-sea exploration technology is the key to the development and utilization of deep-sea resources, and deep-sea buoyancy materials are an important guarantee for deep-sea exploration. In order to improve the pressure resistance and structural stability of deep submersible drag bodies, deep su...
