Abstract
The invention provides a wet processing method of superfine mica iron oxide. The wet processing method includes the steps of firstly, adding mica iron oxide raw materials in a ball mill, adding an ethanol solution which is 95wt% ethanol to serve as the grinding medium, and adding, by the weight percentage of mica iron oxide, 1-2% of grinding auxiliaries, wherein the ethanol solution accounts for 12-15% of the weight of the mica iron oxide raw materials; secondly, performing ball milling by the ball mill in the first step, drying, and dispersing to obtain the superfine mica iron oxide, wherein the ratio of the grinding medium to the materials is (8:1)-(10:1), rotation speed is 300-500r/minute, and ball milling time is 60-120 minutes. The wet processing method has the advantages that the average fineness of the mica iron oxide can reach below 8 micrometers by optimizing operation parameters, the sheet structure of particles can be well kept, and a narrow particle size range is achieved.
