The invention provides a preparation method of high-purity nano copper oxide. According to the method, nano copper oxide precursor slurry is obtained through a multi-phase interface reactor under the action of a surfactant; aging the nanometer copper oxide precursor slurry to obtain nanometer copper oxide precursor aged slurry; carrying out solid-liquid separation on the nanometer copper oxide precursor aged slurry, washing to obtain a nanometer copper oxide precursor filter cake, and obtaining a nanometer copper oxide precursor from the filter cake; and placing the nano copper oxide precursor in a muffle furnace for roasting to obtain nano copper oxide with the particle size of 30-50nm. According to the nano copper oxide with the uniform size, the method is simple, continuous production can be achieved, industrial application is easy, and the prepared product is uniform in particle size and better in comprehensive performance; according to the invention, a multi-phase interface reaction technology is adopted
