摘要
本文简要介绍了固体浮力材料及其国内外研究现状,进一步详细介绍了中科院理化技术研究所对固体浮力材料的相关研究进展。理化所利用自主研发的软化学法制备出高性能空心玻璃微珠,并以多官能团环氧树脂体系为基材,通过真空复合浇注工艺制备出多种规格的固体浮力材料,密度为0.40—0.60g/cm^3,耐压强度为20—100MPa。对密度为0.54g/cm^3的固体浮力材料进行了为期155天的4000m潜标试验,吸水率均小于2%。另外,理化所还开展了全海深固体浮力材料的初步研究,研制出密度分别为0.64g/cm^3和0.68g/cm^3、能满足全海深要求的实验室样块。
The solid buoyancy material and research status at home and abroad were briefly introduced inthis paper, then related research on solid buoyancy material by Technical Institute of Physics and Chemistry(TIPC)of CAS in detail. The high-performance hollow glass microspheres obtained independently through methods ofsoft chemistry by TIPC. By loading this kind of high-performance hollow glass microspheres into high-strengthepoxy resin matrix, solid buoyancy materials of a variety of specification were prepared by pouring in vacuum.Then we obtained samples with densities of 0.40—0.60 g/cm3, hydrostatic compression strength of 20—100 MPa.After submersible buoy test of solid buoyancy material of 0.54 g/cm3 at 4000 m for 155 days, we found that therate of water absorption is less than 2%. In addition, we also conducted the preliminary research on the solidbuoyancy material for full ocean depth; samples can meet the full ocean depth pressure with density of 0.64 g/cm3and 0.68 g/cm3.
