Abstract

The invention relates to a smooth, anti-staining, scratch-resistant and easy-cleaning nano-coating for glass. The nano coating is composed of the following components in parts by weight: 40 to 60 parts of fluorine-modified silicone; 2 to 4 parts of a halogen-based catalyst; 30 to 50 parts of a silane coupling agent; 30 to 40 parts of an inorganic solvent; and 5 to 10 parts of a super-leveling solvent, and the invention also disclose a preparation method and a construction method thereof. The nano coating has the advantages that by binding a plurality of active fluorine bonds to a Si bond in the glass, the fluorine has many excellent characteristics such as water repellency, oil repellency, low friction, abrasion resistance, corrosion resistance and ultraviolet resistance, the ultra-thin nano-coating with anti-fouling, self-cleaning and scratch resistance is finally formed on the surface of the glass, which is simple in method and low in cost. The coating not only has excellent hydrophobicity, but also excellent adhesion between the coating and the glass, and ensures that the coating maintains the superior hydrophobicity for a long time.

Description

technical field [0001] The invention relates to the technical field of nano-coatings, in particular to glass-smooth, anti-fouling, anti-scratch, and easy-to-clean nano coatings, a preparation method and a construction method thereof. Background technique [0002] Today, with the rapid development of electronic smart devices, glass touch screens are widely used due to their advantages of high hardness, non-fragility, and high transparency. In addition, it is easy to cause scratches, and the touch screen is not smooth enough to affect the touch accuracy and smoothness. [0003] The preparation of superhydrophobic surfaces on glass surfaces can not only prevent dust pollution, but also inhibit microorganisms from adhering to the glass surface, which has always been a research hotspot. There are two main ways to prepare superhydrophobic surfaces: one is to construct micro-nano double rough structures on the surface of hydrophobic materials; the other is to obtain rough surface ...
