Abstract

The invention provides a double-glass component reflective coating, which comprises a high-content titanium dioxide layer on the bottom layer and a transparent glass glaze layer on the outer layer. The present invention also provides a method for preparing a reflective coating for a double-glass component, comprising the following preparation steps: S1. preparation of basic glass glaze and transparent glass glaze; S2. preparation of bottom layer slurry; S3. preparation of outer layer slurry; S4. Composite reflective coating coating; S5. Sintering. The composite reflective coating of the invention, the outer layer completely covers the bottom layer, the coating is firmly combined with the embossed back glass, the composite coating has strong adhesion, stronger corrosion resistance than ordinary single-reflective coatings, and good chemical stability , The average visible light reflectivity is high, and the lipophilicity is low, the ink usage is less, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of inorganic reflective coatings, and in particular relates to a reflective coating on the back glass of a photovoltaic double-glass module and a preparation method thereof. Background technique [0002] At present, photovoltaic power generation has become an important solar energy conversion technology, and improving the photovoltaic power generation efficiency will further improve the utilization rate of solar energy. In recent years, photovoltaic double-glass modules have the advantages of high power generation efficiency, and double-glass modules have gradually replaced traditional single-glass modules in the market. According to incomplete statistics from relevant authoritative departments, as of now, the market share of photovoltaic double-glass modules exceeds 20%. Therefore, for the photovoltaic industry, double-glass modules are already a development trend. [0003] The power generation efficiency of double-...
