Abstract
A preparation method for a modified nano-zinc oxide powder includes the following steps: step 1) immersing a raw material zinc oxide into a first active liquid, filtering and drying to obtain an activated zinc oxide; step 2) crushing the activated zinc oxide by an airflow crushing to obtain a crushed zinc oxide; step 3) immersing the crushed zinc oxide into the second active liquid, filtering, drying and grinding to obtain an activated nano-zinc oxide; and step 4) mixing the activated nano-zinc oxide and a surface modifier in a weight ratio of 1:(0.8-1.5) uniformly, drying and grinding to obtain a modified nano-zinc oxide powder with a particle size of 10-90 nm.
