Abstract
The invention discloses an aqueous restoration coating solution for photovoltaic cover glass, a preparation method and application thereof. In the first aspect of the present application, a water-based repair coating solution for photovoltaic module cover glass is provided. The water-based repair coating solution for photovoltaic module cover glass includes, based on the total mass of raw materials: 10-30 parts by mass of alkaline water-solvent silica sol, 8- 26 parts by mass of self-crosslinking acrylic resin, 0.5-2 parts by mass of silane coupling agent, and 0.01-0.05 parts by mass of acidic pH regulator. The water-based repair coating solution provided by this application can be directly applied to the failed glass surface without removing the original film layer, and the film layer can be cured without high temperature treatment, effectively repairing the original anti-reflection film on the coated glass , improve the weather resistance of the anti-reflection film, effectively improve the light transmittance of photovoltaic coated glass and the power generation efficiency of photovoltaic modules.
Description
Photovoltaic cover glass water-based repair coating solution and preparation method and application thereof technical field The application relates to photovoltaic technology field, especially relate to photovoltaic cover glass water-based repair coating solution and preparation method thereof law and application. Background technique Photovoltaic cover glass is a kind of coated glass applied to the surface of photovoltaic modules, and its main function is to ensure light While transmitting, the crystalline silicon cell is protected from damage by the external environment. Photovoltaic cover glass is produced by The surface is coated with an anti-reflection film formed by one or more layers of metal, alloy or metal compound. Reliable anti-reflection coating It can effectively improve the efficiency of solar cells. However, during the outdoor installation and use of photovoltaic modules, dust or industrial pollution The dye will gradually cover the coated cover g...
