The technical developments of solid buoyancy material at home and abroad are summarized. Against the problem that high strength syntactic foam developed by China has higher density, the properties research of syntactic foam is introduced in detail. Meanwhile, the effects of hollow glass microballoons and polymer matrices on the properties of composites are analyzed. Finally, a future outlook for the development of solid buoyancy material is given.%概述了国内外固体浮力材料的研究进展,并针对我国研制的高强度空心玻璃微珠浮力材料密度偏大这一问题,重点介绍了空心玻璃微珠浮力材料的相关性能研究,分析了空心玻璃微珠和基体对浮力材料性能的影响,最后在此基础上展望了我国固体浮力材料的发展方向.
