摘要
采用超分散剂对钛白粉进行表面处理,探寻了超分散剂表面处理的最佳工艺,找到了适宜的表面处理工艺条件(pH=8,50℃,超分散剂用量7%),使用该条件下处理的钛白粉制备白母粒,用于塑料制品中,钛白粉的分散性、白度、遮盖力、加工性能都大大提高。
The optimal conditions for surface treating titanium dioxide with a hyperdispersant was obtained to be pH=8,temperature=50 ,and the content of the amount of hyperdispersant was 7 wt %. The treated titanium dioxide employed in the production of white masterbatch for plastics. Superior behaviors in dispersibility, processablity, and hiding power were observed.
