Abstract

The invention discloses a preparation method and an application method of a waterborne antireflection film coating liquid having an enclosed pore structure. The preparation method includes the following steps: producing an acidic silicon dioxide solution; mixing the acidic silicon dioxide solution with waterborne nano-resin dispersion liquid; selectively adding a certain amount of alkaline silica sol or neutral silica sol according to application situation; finally adding a coating additive to obtain the film coating liquid. Antireflection film-coated glass can be produced by coating glass with the film coating liquid and baking the glass. The film coating liquid is a waterborne system without addition of an organic solution, is beneficial and healthy to environment and human body and is reduced in cost. The film layer has an enclosed pore structure, so that glue sticking on the surface is avoided.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a preparation method and an application method of an aqueous anti-reflection coating solution with a closed-cell structure. Background technique [0002] With people's high attention to climate, environment and sustainable development, the utilization technology of clean energy, especially solar energy, as an inexhaustible clean energy, has been paid more and more attention by people. Improving the conversion efficiency of solar energy is the eternal pursuit of solar energy utilization. One of the methods is to coat the glass cover of the solar module with an anti-reflection film to increase the penetration of sunlight, thereby increasing the output of solar energy. [0003] The anti-reflection coating layer on the glass is obtained by coating the anti-reflection coating liquid on the glass and then drying it. Generally, there are many voids, and it is through the voids tha...
