以环氧树脂为基体,经硅烷活化处理的空心玻璃微珠(HGM)为填充剂,制备了高强浮力材料.采用XRD、FRIR分析了HGM的结构和硅烷处理效果,通过密度测试和单轴静态压缩试验研究了HGM的类型和含量对浮力材料性能的影响,利用SEM和吸水率试验研究了浮力材料的断裂特性和吸水性.结果表明:HGM为无定形结构;硅烷分子接枝在HGM表面,使得HGM与环氧树脂完好结合且两者界面没有间隙沟槽;HGM的较大比压缩强度有利于提高浮力材料的性能;高强浮力材料密度为0.645～0.850 g/cm3,抗压强度为60～93 MPa,比压缩强度为92～112 MPa·cm3·g-1;HGM 含量较少时,浮力材料断裂表面HGM破裂处的基体环氧树脂有拖尾特征,HGM含量增多时,HGM的破坏程度不断增大直至完全破坏;浮力材料具有较好的抗吸水性.
