Abstract

The invention discloses a preparation method of a self-cleaning ceramic nanometer glass antireflective coating material and a coating preparing technique thereof. The reflection deducting coating is formed by coating a composite of amorphous porous silicon dioxide and one or a plurality of titanium dioxide, zirconium dioxide, tin dioxide, ceria, yttria, and the like on the surface of photovaltic glass or common float glass, the reflection deducting coating coated on the surface of the glass has the characteristics of self-cleaning effect, high ceramic hardness and wear resistance. surface antistatic property of dust protection, aging resistance and zero-decrement, can be used for 25 years; and within 250nm-2500nm, the degree of transparency of the photovoltaic glass coated with the reflection deducting coating can be improved by 2.5%-3.5%, and the degree of transparency of the common glass coated with the reflection deducting coating can be improved by 2.8%-3.8%. The nanometer antireflective coating material provided by the invention is a water-based paint, the three wastes are not generated in the preparing course, the preparation method is simple, and the cost is low; and the coating preparing technical process is low in requirement and simple and easy to operate, the energy is saved, thereby being suitable for industrial production in large scale.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing an anti-reflection coating on glass and a method for making an anti-reflection film on glass by using the anti-reflection coating. 【Background technique】 [0002] With the rapid increase of energy consumption and dwindling energy reserves, it is becoming more and more urgent to solve the global energy crisis and the resulting environmental protection issues, which prompt people to start looking for a clean and recyclable new energy. Solar energy is an inexhaustible, clean, environmentally friendly and renewable new energy source, and solar cells are one of the most extensive and effective ways to apply solar energy. However, due to the limitations of solar cell materials and components, the utilization rate of solar energy is not high, and there is great room for development. In order to improve the efficiency of solar photovoltaic modules and the utilization rate of solar energy, people have conti...
