Abstract

The invention discloses a silica sol doped anti-dazzle anti-reflection coating solution as well as a preparation method and application thereof, and relates to the technical field of solar glass. The silica sol-doped anti-dazzle anti-reflection coating solution provided by the invention contains the modified large-size silica sol, the pore forming agent, the silane coupling agent and the diluent, and after the glass surface is coated into a film through a roller coating coating process, particles in the modified large-size silica sol can form a micro-convex structure in a film layer Therefore, the film layer and the glass have an anti-dazzle effect. The film coating solution is prepared by adopting a chemical synthesis method, is suitable for a roll coating process with the highest film coating efficiency, is simple to process and does not need to adopt an atomization spraying mode; And multiple layers of films do not need to be additionally plated, so that the production efficiency can be improved and the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of solar glass, in particular to a silica sol-doped anti-glare and anti-reflection coating solution, a preparation method and an application. Background technique [0002] The original sheet of photovoltaic glass is coated with one or more layers of anti-reflection film (AR film) suede tempered glass, which is used as cover glass on photovoltaic modules. glare effect. [0003] With the popularization and application of photovoltaic modules, photovoltaic modules have gradually entered urban curtain walls, roofs and private applications from power stations in mountains, seaside and deserts. However, existing photovoltaic modules have disadvantages such as strong reflection, glare and light pollution. The application of photovoltaic modules in the city will be limited, and photovoltaic module manufacturers will also put forward higher requirements for photovoltaic modules in areas such as curtain walls, roofs,...
