Abstract

The invention discloses a nanometer antifouling coating liquid. The preparation raw materials comprise the following components: tetraethyl orthosilicate, organic modifiers, deionized water, organic solvents, and catalysts. After the nanometer antifouling coating liquid coats the surface of a photovoltaic glass substrate, a firm nanometer antifouling coating with a thickness of about tens of nanometers can be formed on the surface of the photovoltaic glass substrate in a self-assembly manner, the nanometer antifouling coating is colorless, odorless, smooth and transparent, and has the properties which are similar to those of a lotus leaf surface, such as good water resistance, oil proofness, anti-fouling performance and the like. Most of polar groups such as silicon hydroxyl in the photovoltaic glass substrate are isolated from the outside world by the nanometer antifouling coating, and dust is not easy to accumulate on the surface of a photovoltaic power generation panel inclined at an angle of a certain degree under the protection of the nanometer coating, so that the difficulty and frequency of cleaning the photovoltaic power generation panel are reduced, operation and maintenance costs of a photovoltaic power station are reduced, and the yield rate of the photovoltaic power generation is improved.
