Abstract

The invention relates to the technical field of automobile glass, in particular to a functional coating of the automobile glass, and specifically provides an automobile glass with an anti-reflection coating and a manufacturing method thereof. The automotive glass includes at least one curved glass substrate, an anti-reflection coating is formed on at least one surface of the glass substrate, the anti-reflection coating has a porous structure, and the porous structure is softened during the softening process of the glass substrate formed in. The invention can match and combine the formation process of the anti-reflection coating with the bending and forming process of the automobile glass, and only needs one high-temperature heating, which saves the independent high-temperature heating step necessary for the anti-reflection coating, simplifies the production process, and reduces energy consumption. It not only has economic benefits, but also has environmental benefits; at the same time, the material of the anti-reflection coating is environmentally friendly, economical and cheap, and is suitable for industrial production.

Description

Technical field: [0001] The invention relates to the technical field of automobile glass, in particular to a functional coating of the automobile glass, and specifically provides an automobile glass with an anti-reflection coating and a manufacturing method thereof. Background technique: [0002] The anti-reflection coating can reduce the reflected light on the surface of the substrate, increase the light transmission of the substrate, have an anti-reflection effect, and can also reduce or eliminate stray light. It has been widely used in optical glass, solar photovoltaic glass and electronic glass. application. In the prior art, the anti-reflection coating can be prepared on the surface of the substrate by sol-gel method, chemical vapor deposition method, physical vapor deposition method, etc. For example, patent CN201711052282. A production method for preparing photovoltaic glass from a solution, comprising the following steps: pretreating the surface of the glass, coatin...
