Abstract

The invention discloses a nano super-hydrophobic coating which comprises the following materials in parts by mass: 50-3650 parts of nano silicon dioxide, 20-120 parts of hexamethyl-disilazane, 350-600 parts of a solvent, 200-450 parts of organic silicon resin and 5-25 parts of a curing agent, wherein the curing agent is aliphatic polyamine; and the solvent is one or a combination of some of absolute ethyl alcohol, normal propyl alcohol, isopropanol, acetone, tetrahydrofuran, N,N-dimethyl acetamide or N,N-dimethylformamide, methylbenzene and dimethylbenzene. The production technology comprises the steps: S1, preparing a filling solution, S2, preparing a super-hydrophobic solution, and S3, preparing the super-hydrophobic coating. The raw materials adopted by the coating are simple and easy to obtain; a preparation process is easy; the production cost is low; the prepared super-hydrophobic coating has the advantages of large contact angle, small roll angle, high light transmittance and the like, is long in service life and strong in adhesion and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of superhydrophobic coatings, in particular to a nanometer superhydrophobic coating and a production process thereof. Background technique [0002] Super-hydrophobic materials have the property of not sticking to water on the surface, which can be used to prevent metal surfaces from rusting, which is beneficial to the small water resistance of ships. It can also prevent snow accumulation and reduce maintenance costs when used on outdoor wires. It is used in photovoltaic and photothermal fields. Its self-cleaning function can prevent dust and dirt from adhering to the glass cover, greatly improving the conversion rate of photovoltaic and thermal photovoltaic equipment. [0003] Superhydrophobic materials usually have two requirements: one is that the contact angle of water droplets on the surface of the material needs to be above 150°, and the other is that the rolling angle of water droplets on the surface o...
