The invention discloses a water-based environment-friendly white glaze for high-reflection and anti-PID photovoltaic backplane glass and a preparation method and application thereof. , it has high reflectivity to visible light (≥78%), and is resistant to PID (potential-induced degradation). Wherein, the softening temperature of the low-melting glass powder is 450-550°C, and the full melting temperature is 520-560°C, so that the water-based environmentally friendly white glaze can be completely melted in a short time within the tempering temperature range of 600-720°C, and the low-melting glass powder The linear expansion coefficient of the glass is 80‑85*10 ‑7 /K (30‑300℃), which is similar to the linear expansion coefficient of the base glass, so that the stress between the two is similar during the cooling process, which ensures the adhesion of the glaze layer. and dimensional stability of glazed glass. Titanium dioxide is prepared by the chlorination method, with extremely low impurity content, and is coated with silicon oxide and aluminum oxide, which can block the lattice defects caused by titanium dioxide under ultraviolet irradiation conditions, shield the photoactivation point on its surface, and improve the resistance. PID performance. |
