Abstract

The invention discloses an MgF2 / oxide composite membrane used for anti-reflection of a glass surface. The MgF2 / oxide composite membrane is of an MgF2 / Al2O3 or MgF2 / SiO2 dual-layer membrane structure; and an Al2O3 or SiO2 buffer layer is inserted between an MgF2 membrane and a glass substrate. Therefore, on the premise of improving an anti-reflection effect of a membrane system, by using the good wetting property of the Al2O3 and SiO2 layer and the glass surface, an adhesive force between a membrane and the substrate is enhanced; the firmness of the MgF2 membrane is improved; the performance advantage of hard texture of an Al2O3 and SiO2 coating can be brought into play; the scratch resistance of the overall membrane system is improved; the mechanical performance of the overall membrane system is improved; and a comprehensive performance requirement on an anti-reflection membrane on a photovoltaic glass surface in a poor working environment can be met.

Description

technical field [0001] The present invention relates to anti-reflection film, further refers to the MgF used for anti-reflection on glass surface 2 / oxide composite film. Background technique [0002] As an important branch of modern optical films, AR coatings have been widely used in industry, agriculture, construction, transportation, military and other fields. Anti-reflection coatings are playing an increasingly important role in lenses in daily life, emerging flat panel displays, environmentally friendly solar cells, cutting-edge laser devices, etc. At present, the structure of anti-reflection coating can be generally divided into single-layer and multi-layer. Among them, single-layer anti-reflection coating has simple structure, low process cost, and the same coating material can be coated on glass with different refractive index. The transparent effect is not as good as that of multi-layer film, and it is still widely used, especially on the surface of solar photovo...
