Method for preparing nano tin dioxide/composited nano tin dioxide through high-energy ball milling method

The invention discloses a method for preparing nano tin dioxide/composited nano tin dioxide through a high-energy ball milling method. The preparation method is implemented according to the following steps: (1) weighing raw materials; (2) mixing three milling balls with different particle sizes to form mixed milling balls, putting the mixed milling balls and the raw materials into a ball milling machine tank body together, adding absolute ethyl alcohol to start ball milling, so as to obtain the ball-milled nano tin dioxide or composited nano tin dioxide powder; (3) spreading the ball-milled nano tin dioxide or composited nano tin dioxide powder in a tray for 24-28 hours in the air, and finally obtaining the nano tin dioxide/composited nano tin dioxide after the absolute ethyl alcohol is completely volatilized. The method for preparing nano tin dioxide/composited nano tin dioxide through the high-energy ball milling method solves the problems of long production period, easy segregation of oxide and complex process existing in the existing preparation process of the nano tin dioxide/composited nano tin dioxide.
