Abstract
The invention relates to preparation of membrane materials and aims to provide a preparation method for a solar power encapsulation glass reflection reducing coating with high mechanical strength and self-cleaning capacity. The method comprises the following steps: adding tetraethyl orthosilicate in a low grade fatty alcohol solvent with stirring and uniformly mixing the two; adding water at first and the pore forming agent, citric acid, next, mixing an obtained solution, adding inorganic acid or organic acid to adjust the pH value of the solution to be between 2 and 3, and allowing the solution to react for 4 hours at a temperature of 60 DEG C; adding alkyl siloxane, and allowing the solution to continue to react for 6 hours at a temperature of 60 DEG C after uniform mixing so as to obtain SiO2 polymer sol used for the reflection reducing coating; carrying out coating by applying the sol on the surface of rinsed clean common glass or ultra-white glass, and carrying out heat treatment after the surface is dried so as to obtain the product of the solar power encapsulation glass reflection reducing coating. According to the invention, the pore forming agent with low decomposition temperature is used to substitute commonly used pore forming agents so as to decrease heat treatment temperature for the coating; under the condition of low heat treatment temperature, the pore forming agent is removed, and the coating is cured, thereby improving transmittance of coated glass and retaining hydrophobic automatical cleaning performance of the coating.
Description
technical field [0001] The invention relates to the preparation of film materials, in particular to a preparation method for high mechanical strength and self-cleaning solar encapsulation glass anti-reflection film. Background technique [0002] Solar encapsulation glass is a special glass installed in the solar cell encapsulation box to protect solar cell modules. Sunlight needs to pass through the encapsulation glass to reach the surface of the solar cell and be used by it. For the same solar cell, the light intensity after passing through the encapsulation glass determines the power generation efficiency of the solar cell. The anti-reflection film is a thin film coated on the surface of solar glass to improve the transmittance of sunlight. [0003] SiO 2 The particle sol was prepared by SiO 2 Particle film is an early type of anti-reflection film, which consists of SiO with a particle size of tens to 100 nanometers 2 The high-porosity loose structure formed by the acc...
