Abstract

The invention discloses a preparation method of a multi-layer SiO2 inorganic anti-reflection film. The preparation method comprises steps as follows: (1) pretreatment of a glass substrate; (2) preparation of SiO2 sol; (3) sol coating and molding; (4) film solidification; (5) cooling, detection and packaging. The multi-layer SiO2 inorganic anti-reflection film has excellent anti-reflection performance, very excellent thixotropy and excellent chemical stability and is simple in preparation process.

Description

technical field [0001] The invention relates to a multilayer SiO 2 The invention discloses a method for preparing an inorganic anti-reflection film, belonging to the technical field of anti-reflection film preparation. Background technique [0002] The anti-reflection film of the solar silicon cell device is mainly used on the surface of the encapsulation glass to improve the sunlight transmittance of the encapsulation glass and protect the encapsulation glass. The annual output of float ultra-white glass used to encapsulate solar cells is more than 3.5 million square meters per year, and it is increasing year by year. Compared with organic membranes, inorganic membranes have the advantages of excellent thermal and chemical stability, microbial resistance and high mechanical strength, and have great application potential in the fields of catalysis, gas separation, gas treatment, and membrane reactors. [0003] With the continuous development and research of anti-reflection...
