Abstract

The invention discloses a preparation method for a composite modified facing protective layer. The preparation method comprises the following step (1) of coating base materials on a carrier by spraying, and baking the carrier; and the step (2) of coating surface materials on the bottom layer by spraying, and baking the bottom layer. The base materials and the surface materials are both prepared from inorganic light diffusants and water glass, the mass proportions of the inorganic light diffusants and the water glass in the base materials and the surface materials are different, and the particle sizes of the inorganic light diffusants in the base materials and the surface materials are different. Due to the difference of the particle sizes and mass concentrations of light diffusant materials of different layers in a multi-layer structure, longitudinal distribution of media is not uniform, a scattering phenomenon is very easy to occur, and the haze is improved while the light transmittance is ensured. A method of coating one layer and baking one layer is adopted, and since each layer is thin, on one hand, water vapor is easy to release, and on the other hand, water vapor needing to be released is less; the problem of surface bulging in the baking process is solved, and the problem of water resistance of water glass is solved through a baking process.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of a composite modified decorative finish protective layer and a power generation building material comprising the composite modified decorative decorative protective layer. Background technique [0002] At present, the main way to combine cities and solar energy is building integrated power generation (BIPV), but the photovoltaic modules used in conventional BIPV generally appear dark blue, gray, and black, and their color, texture, and texture are not beautiful, and they cannot meet the aesthetics of buildings. Requirements, it is difficult to be highly integrated with buildings, these shortcomings limit the widespread use of photovoltaic modules in buildings. [0003] Although it is possible to make power generation building materials have the same appearance as natural stone such as marble and granite, and is no longer limited to th...
