Problems solved by technology
[0006] Generally, after the hydrophobic coating is applied to the solid surface, although it can have waterproof properties, but after the dust touches the solid surface, the liquid cannot efficiently roll on the solid surface to remove the dust, so the self-cleaning function cannot be effectively achieved
Furthermore, after coating the solid surface with a hydrophobic coating, it cannot effectively prevent the ultraviolet light from harming the human body and organic matter.

Embodiment Construction
[0040] According to the transparent coating structure provided by the present invention, the tetrapod cone (Tetrapod) or rod-shaped (rod) nano-zinc oxide powder 10 is used to achieve the effect of absorbing and shielding ultraviolet light, and then through the fluorocarbon functional group (CF X ), hydrocarbon functional groups (CH X ) or the macromolecules of the above two functional groups modify the surface of the nano-zinc oxide powder 10 to form a transparent coating structure with a fine ciliated rough surface structure, and has the functions of shielding ultraviolet light and hydrophobic / oil.
[0041] And, the manufacturing method of tetrapod cone-shaped or rod-shaped nano-zinc oxide powder 10 is to use non-consumable electrode-type DC plasma under normal pressure and atmosphere control containing nitrogen to introduce solid-state zinc raw materials into the plasma zone (plasma zone) ) to vaporize it, and then use a large amount of oxygen and nitrogen-containing gas to ...

Abstract
The transparent coating structure with ultraviolet sheltering function and hydrophobic / lipophobic function includes zinc oxide powder, transparent insulating layer on the surface of zinc oxide powder, and polymer coating for the surface modification of the transparent insulating layer. The present invention includes amino group for the surface modification of the transparent insulating layer. The transparent insulating layer of SiO2 and the zinc oxide powder form one ZnO-SiO2 core-shell structure. The present invention adopts polymer with carbofluoro functional group in surface modification of nanometer zinc oxide powder to form fine hairy rough surface structure and the transparent coating structure with ultraviolet sheltering function and hydrophobic / lipophobic function.
Description
technical field [0001] The invention relates to a coating structure, in particular to a coating structure utilizing fluorocarbon (CF X ), hydrocarbons (CH X ) or polymers with the above two functional groups modify the surface of nano-zinc oxide powder to form a transparent coating structure with UV-shielding and hydrophobic / oily functions. Background technique [0002] The leaves of many plants in nature exhibit their superhydrophobicity due to their unique microstructure and surface properties. The superhydrophobic surface is characterized by the formation of approximately spherical droplets of water on them, such as lotus leaves in nature. Forming and rolling on the surface can take away the dust at the same time, so that the leaf surface can be kept clean and bright, and has the function of self-cleaning (self-cleaning). The self-cleaning phenomenon on the surface of the lotus leaf is caused by the low surface tension and surface roughness of the lotus leaf. [0003] ...
