Abstract

The invention relates to an ultrasound preparation method of nano zinc oxide particles. In the ultrasound preparation method, zinc powder is put in a roller vibration mill for grinding to obtain nano zinc powder. The ultrasound preparation method is characterized by comprising the following steps: placing the prepared nano zinc powder and deionized water in a beaker at a weight ratio of 1: 60, then putting the beaker in an ultrasonic cleaning device with the frequency of 70-99 Hz, and carry out ultrasonic treatment for 24-30 hours, so as to obtain a white turbid solution; and standing the turbid solution for 3-5 minutes at room temperature, sucking the turbid solution to another clean beaker again by using a suction tube, putting the beaker in a constant temperature drying oven at the temperature of 60 DEG C, drying for 24 hours, and grinding and dispersing the obtained product by using an agate mortar after finishing drying, so that the nano zinc oxide is obtained. In the invention, the nano zinc powder is processed by ultrasonic treatment so that the nano zinc oxide is obtained; and the operation is simple and convenient, the cost is low, the environment is not polluted, preparation is carried out at low temperature, and the obtained nano zinc oxide has high purity, no other impurity phases and even topography. The ultrasound preparation method is easy to achieve industrial production and has a wide application prospect.
