The invention discloses a preparation method for modified nanometer zinc oxide. The preparation method comprises the following steps: immersing nanometer zinc oxide into a hydrochloric acid solution,then filtering nanometer zinc oxide out of the hydrochloric acid solution, adding water, then adding a barium stearate dispersant so as to obtain a nanometer zinc oxide dispersion, adding the nanometer zinc oxide dispersion into an ultrasonic generator, adding a soaking modifying solution, carrying out ultrasonic treatment under heating so as to obtain a modified nanometer zinc oxide solution, filtering the modified nanometer zinc oxide solution, placing filtered modified nanometer zinc oxide into a drying oven for drying, placing dried modified nanometer zinc oxide into a muffle furnace for calcination, and after calcination is completed, taking calcined modified nanometer zinc oxide out of the muffle furnace so as to obtain a finished product, namely, the modified nanometer zinc oxide. The preparation method for the modified nanometer zinc oxide provided by the invention has the following advantages: when the nanometer zinc oxide dispersion is modified by soaking, nanometer zinc oxide particles are located in a good dispersion state in a liquid by utilizing ultrasonic wave through ultrasonic operation, so the phenomenon of agglomeration among the nanometer zinc oxide particles can be reduced; the process is easy to operate; and the modified nanometer zinc oxide prepared by using the preparation method provided by the invention has good dispersity and facilitates realizing industrial production.
