Abstract

The invention relates to the technical field of anti-reflection and anti-reflection coating solution, in particular to a self-cleaning high anti-reflection coating solution and a preparation method thereof and a self-cleaning high anti-reflection solar glass. In the method, a nano-core-shell silica microsphere sol is prepared first, Then through a specific process, the surface of the core-shell structure silica microspheres is covered with a titanium dioxide layer nano-core-shell silica / titania microsphere sol, and finally diluted to a solid content of 3‑10% to obtain a self-cleaning high anti-reflection coating solution. While reducing the mass ratio of titanium dioxide / silicon dioxide, the present invention has the largest effective exposure area, solves the technical problem of increasing light transmittance and self-cleaning effect, and greatly improves the existing technology of solid silicon dioxide The problem of low porosity of the film layer as the main component.

Description

Technical field [0001] The present invention relates to the technical field of anti-reflection reduction coating fluid, specifically relates to a self-cleaning high-reflection coating solution and preparation method thereof and self-cleaning high-reflection solar glass. Background [0002] Solar photovoltaic is currently one of the most promising clean energy, in order to improve the photoelectric conversion efficiency, most of the photovoltaic glass manufacturers are in the effort to improve the transmittance of photovoltaic glass, that is, the use of light interference principle in the glass to add a layer of anti-reflection film, many of the anti-reflection coating fluids on the market mostly reach the effect of increasing the transmittance of about 3%, but the room for further improvement is very small. With the development of modern industry and urban construction, the air and water and other environmental pollution is serious, making it easy for pollution sources such as du...
