Abstract

The invention discloses a coating solution for a double-layer anti-reflection film of photovoltaic glass, which includes a first layer of coating solution and a second layer of coating solution, and the first layer of coating solution is composed of the following raw materials in terms of mass percentage: silane 8 ‑20%; metal compound 0.1‑3.5%; water 5‑15%; catalyst 0.1‑5%; curing agent 0.05‑0.5%; solvent 60‑84%; : Silane 5‑15%; Water 8‑20%; Catalyst 0.1‑2%; Active monomer 0.5‑2%; Initiator 0.01‑0.2%; Emulsifier 0.05‑0.5%; Molecular weight regulator 0.05‑0.5%; Agent 0.01‑0.2%; solvent 60‑84%. The application of the present invention makes the light transmittance of the photovoltaic glass higher, so that the power generation power of the module is higher; the weather resistance of the double-layer coating is also better than that of the single-layer coating, ensuring that the solar module maintains stable and continuous performance in various harsh environments Generating power.

Description

technical field [0001] The invention relates to a coating solution, in particular to a coating solution for a double-layer anti-reflection film of photovoltaic glass and a preparation method thereof. Background technique [0002] In recent years, most manufacturers of solar photovoltaic glass adopt roller coating process to coat a layer of anti-reflection coating on the surface of solar photovoltaic glass, and then temper it at about 700°C, so that the light transmittance of photovoltaic glass is increased by about 2-2.4 %, greatly improving the power generation efficiency of solar cells. [0003] Regarding the double-layer coating, Chinese invention patent No. 201010150748.1 discloses a method for preparing photovoltaic glass coated with a double-layer anti-reflection film, which is composed of a high-refractive index oxide layer and porous silicon oxide. The bonding force of this double-layer anti-reflection film to the glass substrate has been improved to a certain exten...
