Composite coating and preparation method therefor, silicone rubber protective sleeve and insulator

Abstract

A method of preparing the composite coating includes the steps of: coating an adhesive solution on a substrate to obtain a liquid film; embedding hydrophobically modified tetrapod-shaped zinc oxide powder into a surface of the liquid film and then embedding hydrophobically modified nano metal oxide powder into the surface of the liquid film, and fully curing the liquid film to obtain a composite coating having a micro-nano structure.
