| Abstract: | 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. |
| Keywords: | calcined kaolin coupling agents surfaces modification cable material application experiment |
