【摘要】 采用钛酸脂偶联剂活化硅藻土颗粒表面并探讨其活化机理,制备了甲基乙烯基硅橡胶/硅藻土复合材料。通过扫描电子显微镜(SEM)对硅藻土表面和复合材料断口进行表征。研究了纯硅橡胶和复合材料的压缩性能,初步分析了压缩变形机理。结果显示,活化后硅藻土的平均活化度为98%,硅藻土含量为30%时复合材料的压缩变形回弹量最大。更多还原

【Abstract】 The surface of diatomite particles was modified using titanate coupling agent and the activation mechanism was discussed,the composite materials were fabricated with methyl vinyl silicone rubber and diatomite. The diatomite surface and fracture of composite materials were charactered by SEM.The compression properties of simple silicone rubber and composite materials were researched.The results showed that the average activation grade of diatomite particles modified was 98%,the maximum compression deformation springback of composite materials was obtained while the content of diatomite was up to 30%.更多还原
