Abstract

The invention discloses an ultra-dispersion modification method for wave-absorbing powder. The ultra-dispersion modification method comprises the following steps: preparation of wave-absorbing powder, namely, firstly cleaning the wave-absorbing powder, then putting the wave-absorbing powder into a ball mill for ball milling, putting the wave-absorbing material after ball milling into a placing tank, cooling to room temperature, and then sequentially carrying out ultrasonic treatment, drying and grinding to obtain the wave-absorbing powder for later use; mixing, namely placing the wave-absorbing powder for later use in a stirrer, then adding a dispersing agent, starting the stirrer, and carrying out uniformly mixing through the stirrer to obtain a mixture; and modification, namely adding a certain amount of modifier into the mixture, carrying out calcining through calcining equipment, carrying out cooling treatment, and finally cooling the modified material to room temperature to obtain the modified wave-absorbing powder. According to the ultra-dispersion modification method for the wave-absorbing powder, under the action of the modifier, the inner wall of the wave-absorbing powder is conveniently modified, and the overall performance of the wave-absorbing powder is improved.

Description

technical field [0001] The present application relates to the technical field of wave-absorbing powders, in particular to a method for ultra-dispersion modification of wave-absorbing powders. Background technique [0002] With the development of modern science and technology, the impact of electromagnetic radiation on the environment and people is increasing. The electromagnetic waves released by electronic products will cause electromagnetic interference to other electronic devices around them, making them work abnormally. Due to market demand, the so-called wave-absorbing material refers to a type of material that can absorb or greatly reduce the electromagnetic wave energy received by its surface, thereby reducing the interference of electromagnetic waves. In addition to having a high absorption rate, it is also required to have properties such as light weight, temperature resistance, moisture resistance, and corrosion resistance. [0003] At present, the overall dispers...
