| titleOfInvention |
Method for producing cationically modified silica and cationically modified silica dispersion |
| abstract |
Provided is a means capable of introducing a sufficient amount of a cationic group onto the surface of silica particles even in a case where a silica raw material having a high silica concentration is used while occurrence of gelation is suppressed at the time of or after addition of a silane coupling agent in production of a cationically modified silica dispersion including modifying raw silica using a silane coupling agent.Adding a silane coupling agent having a cationic group to a silica raw material in which a zeta potential shows a negative value, and causing the silica raw material to react with the silane coupling agent to obtain a cationically modified silica. |
