Problems solved by technology

Nano-zinc oxide has the characteristics of large specific surface area and specific surface energy, and is easy to agglomerate; on the other hand, the surface of nano-zinc oxide is very polar, and it is not easy to disperse uniformly in organic media, which greatly limits its nano-effect. ; Therefore, it is necessary to modify the nano-zinc oxide to improve the dispersion performance of the nano-zinc oxide
[0003] The existing modified nano-zinc oxide has poor dispersion performance, poor safety performance during use, and easy to reduce stability

Abstract

The invention discloses a preparation method of high-dispersion modified nano-zinc oxide, and particularly relates to the technical field of nano-zinc oxide. The high dispersion performance of the modified nano zinc oxide can be effectively improved, and the safety performance is better; in the step 1, the nano zinc oxide is subjected to modification scattering treatment, so that the structure distribution uniformity and the high dispersion performance of the nano zinc oxide can be effectively improved; the first soaking modification treatment is carried out on the nano zinc oxide in the step 2, so that the high dispersion performance, hydrophilicity and thixotropy of the nano zinc oxide can be effectively enhanced, the second soaking modification treatment is carried out on the nano zinc oxide in the step 3, and the third soaking modification treatment is carried out on the nano zinc oxide in the step 4, and thus the high dispersion performance, the weather resistance and the heat insulation performance of the nano zinc oxide can be further enhanced; in the step 5, the nano-zinc oxide is modified by a vacuum plasma cleaning machine so that the modification performance of the nano-zinc oxide can be further ensured.
