Abstract

The invention discloses solar glass antireflection antifouling paint with high antireflection performance and high weather resistance and a production method of the solar glass antireflection antifouling paint. The solar glass antireflection antifouling paint is prepared from alkaline silica gel, poly SiO2, aluminium dihydrogen phosphate, silicon phosphate, phosphoric acid, a surfactant and deionized water. The production method comprises the following steps: a porous silicon dioxide core generated in ethyl silicate hydrolysis is covered with another hard silicon dioxide shell, silicon dioxide particles in the paint have a core-shell structure, the silicon dioxide core formation and the silicon dioxide shell covering are carried out at the same time, aluminium dihydrogen phosphate and silicate phosphate are used as a silicon dioxide curing agent to enhance the weather resistance of an antireflection membrane. The problem that antireflection performance and the weather resisting performance of conventional solar glass self-cleaning antireflection paint can offset each other is solved, the power generating efficiency of a solar cell can be improved and stabilized greatly, and the maintenance management cost of the solar cell can be reduced.

Description

technical field [0001] The invention relates to an antireflection and antifouling coating for solar glass and a production method thereof, in particular to an antireflection and antifouling coating for solar glass with high weather resistance and high antireflection containing aluminum phosphate and silicon phosphate curing agent and a production method thereof, which belongs to the new materials and new energy fields. Background technique [0002] Crystalline silicon solar cell modules are generally composed of solar glass cover plate coated with anti-reflection film, solar cell silicon wafer, battery back plate and EVA film, which are glued and pressed together, and then installed into a fixed frame. The visible light transmittance of solar cell module packaging glass is generally 91.6%, and the single surface reflectance of solar glass is about 4%. If the surface of the solar glass is coated with an anti-reflection film with a thickness of 120-150nm, the transmittance of...
