Preparation method for nanometer anti-reflection self-cleaning coating solution

Abstract

The invention discloses a preparation method for a nanometer anti-reflection self-cleaning coating solution. The nanometer anti-reflection self-cleaning coating solution comprises the following components in percentage by mass: 10-25% of siloxy compound, 5-15% of additive, 1-5% of surface modifier and 60-80% of solvent. The preparation method comprises the steps as follows: adding the siloxy compound, the additive and the surface modifier into the solvent at a uniform speed in a stirring state by adopting the high gravity technology, and stirring at a stirring speed of 100-500 rpm in high gravity equipment until nanometer particles of less than 100 nm are formed in the solution, namely obtaining the nanometer anti-reflection self-cleaning coating solution. The coating solution prepared with the method can effectively improve the power generation efficiency of a photovoltaic cell assembly and avoid the shortcoming that the photovoltaic cell assembly is difficult to clean in the using process; and the preparation method is high in photoelectric efficiency, simple in preparation process and low in cost, is suitable for industrial large-scale production, and can reduce the photovoltaic power generation cost and promote the development of photovoltaic industry.
