The invention relates to a method for preparing nanometer Zinc Oxide by hydrothermal method. The main content of which is the zinc salt and ammonia as raw materials, polyacrylate dispersing control agent, water as solvent, at 100 to 120 DEG C under atmospheric pressure reaction for 15 hours, average grain size is 87 ~ 460 nm and the dispersion in aqueous solution of Zinc Oxide / polyacrylate composite nanoparticles. The particle size of 2 to 5 nm by Zinc Oxide nano particle polyacrylate molecular chain wrapped. The utility model is characterized in that the process is simple, the preparation cost is low, the particle size of the Zinc Oxide particle is small, the homogeneity is good, and the powder can be stably dispersed in the aqueous solution in the form of composite particles.
