界面活化处理对固体浮力材料力学性能的影响

Influence of Surface Treatment on Mechanical Property of Epoxy Resin Solid Buoyancy Materials

采用2种方法(偶联剂处理和碱刻蚀+偶联剂处理)分别对空心玻璃微球进行界面活化处理,制备了轻质、高强的空心玻璃微球/环氧树脂固体浮力材料。通过红外光谱分析、扫描电镜、压缩性能测试和密度测试等表征手段研究了材料的结构、密度和压缩性能。研究表明,2种方法都能改善空心玻璃微球与环氧树脂之间的相容性和界面结合力,使材料的实际密度更接近理论密度,同时能显著提升材料的压缩强度。当空心玻璃微球填充量在10%时,相比未处理工艺制备的固体浮力材料,偶联剂处理和碱刻蚀+偶联剂处理得到的固体浮力材料的压缩强度分别提升18 MPa和22 MPa,上升幅度分别为13.5%和16.5%。

Epoxy resin soild buoyancy materials with low density and high intensity were reinforced with hollow glass microballs （HGM）, that were treated by two different methods. The infrared analysis, transmission electron microscopy, compression preformance test and density test were employed to characterize the structure, density, and compression property of this material. It is demonstrated that the compatibility and interracial adhesion of the HGM and epoxy resin are improved by both methods, the actual density of the materials is much closer to the theoretical density, and the compression strength is enhanced greatly as well. When the faction of the HGM filler is between 10%-20 %, the compression strength of the cured materials synthesized by both methods is improved by 18 MPa and 22 MPa, respectively.
