摘要
利用硅烷/脂肪酸复配偶联剂对煤系煅烧高岭土进行表面改性实验,通过红外光谱分析和活化率测定表明,硅烷偶联剂接枝到煅烧高岭土表面,改性的煅烧高岭土由亲水性变为亲油性;实验中探讨了煅烧高岭土的粒度和填充量对电缆胶料物理机械性能的影响。表面改性的煅烧高岭土用于电缆胶料,能明显提高其物理机械性能,各项指标达到或超过有关技术标准。
The coal-serial calcined kaolin in Yichang were modified by the coupling agent of silane/steric acid. Infrared spectrum analysis and activation rate determination indicate that the modified calcined kaolin changed from hydrophilic to oleophilic through silane coupling agent stem grafting to calcined kaolin surface. The influence of sizes and filler loading of modification calcined kaolin to the mechanical performance in cable material was discussed in this research. The filling properties of modified calcined kaolin in the cable material are greatly improved and can satify relative technical standard.
