Modification of (y)-Al2O3 as Ink-Jet Printing Paper Coating Pigment by Coupling Agents
γ-Al2O3 namely activated alumina or alumina gel is widely used as a pigment on the inkjet paper at present.But it is easy to come out a particles agglomeration problem to restrict its application.In this paper,the γ-Al2O3 with coupling agents were modified to improve its dispersion in water.In the modification process,the he main modification parameters such as aluminum-zirconium complex oligomeric coupling agent TL-3A were selected to study.The parameters of addition,modification time and modification temperature were discussed.During the experiment,the best modification conditions were determined via orthogonal experiments.The polydispersity index PDI was used the target parameters to inspect via orthogonal experiments results and the affected factors.We found the best addition quantity of coupling agent,modification time and modification temperature to reach the minimum of the polydispersity index PDI introduction.The results showed that the best condition for carbonization alumina was:the best condition for export γ-Al2O3 2.0%,modification time 30min,modification temperature 50℃.
