Nano-zinc oxide dispersion liquid as well as preparation method and application thereof

Abstract

The invention relates to the technical field of polyester antibacterial materials, and discloses a nano-zinc oxide dispersion liquid, a preparation method and application thereof, polycarboxylate is used as a modifier of nano-zinc oxide in the dispersion liquid, and the polycarboxylate can be chemically bonded with the nano-zinc oxide, so that the surface of the nano-zinc oxide is grafted with the polycarboxylate; the steric hindrance functional group and the negative charge functional group on the molecular chain of the polycarboxylate can generate repulsion and spacing among nano-zinc oxide particles, so that the dispersity of the nano-zinc oxide in a polar solution is remarkably improved, in addition, the dispersion liquid can be stably stored for more than 30 days, and the stability cannot be remarkably changed after being heated, so that the dispersion liquid has a good application prospect. And the production efficiency can be obviously improved during large-scale production.
