Abstract

The invention discloses a self-cleaning structure and a manufacturing method thereof. The self-cleaning structure comprises a base material, wherein a graphical structural layer is formed on the base material, and the graphical structural layer is coated with a hydrophobic coating; the graphical structural layer is a bulged matrix formed on the surface of the base material, and the height of bulge is greater than or equal to 500nm; the thickness of the hydrophobic coating is less than or equal to 100 nm; and the base material is made of glass, ceramic, metal, plastic, glaze or enamel. According to the self-cleaning structure, the graphical structural layer on the surface of the base material is integrated with the base material and cannot fall off, so that the quality and the service life of a product are effectively guaranteed; and the graphical structural layer is coated with the hydrophobic coating, so that the self-cleaning effect of the self-cleaning structure disclosed by the invention is enhanced.

Description

【Technical field】 [0001] The invention belongs to the technical field of material processing, and in particular relates to a self-cleaning structure and a manufacturing method thereof. 【Background technique】 [0002] Self-cleaning and self-cleaning materials with high efficiency and anti-pollution have attracted much attention. Most of the existing anti-pollution and self-cleaning materials achieve their self-cleaning effect by immobilizing photocatalytic or highly hydrophilic nanoparticles, but the existing technology cannot guarantee the immobilization effect of nanoparticles, which affects the quality and quality of products. life. 【Content of invention】 [0003] The purpose of the present invention is to provide a self-cleaning structure with simple structure and convenient manufacture and its manufacturing method on the surface of the substrate; it can be used on the surface structure of glass, ceramics, metal, plastic substrates or glazed, enamel and other substrate...
