Problems solved by technology

[0006] (1) Prepare phosphoric acid as a phosphoric acid solution, add it to a beaker, add aluminum hydroxide, and obtain intermediate A, add mullite powder and silicon powder to intermediate A, stir evenly, and solidify to obtain the high-temperature binder. The high-temperature binder is added to the coating, which solves the problem of pungent odor produced by the existing coating material when grilled, and environmental pollution caused by fluorine, lead, and cadmium elements;

Abstract

The invention discloses an environment-friendly high-reflection coating material and a preparation method thereof. The preparation method comprises the steps that an inorganic environment-friendly flux is melted, quenched, dried and then subjected to ball milling, titanium dioxide, calcium sulfate, the inorganic environment-friendly flux, zirconium silicate, tin oxide, barium sulfate, high-reflection filler and a high-temperature binder are mixed and subjected to ball milling dispersion, and steps of precipitating, dehydrating, drying and powdering are carried out to obtain a blended material; after porous modification, the obtained high-reflection filler powder is internally provided with a large number of micropores similar to visible light and near-infrared light in wavelength besides gaps formed by powder accumulation, the light reflection capacity of the high-reflection filler is further improved, the thermal expansion coefficient of the high-reflection filler is matched with that of glass, shrinkage expansion is small, the glass does not deform and is resistant to chemical corrosion, so that the purpose of improving the visible light reflectivity of the coating material is achieved.

Description

technical field [0001] The invention relates to the field of coating materials, in particular to an environment-friendly high-reflection coating material and a preparation method thereof. Background technique [0002] A solar cell is a semiconductor device with photoelectric conversion characteristics. It directly converts solar radiation energy into direct current. It is the most basic unit of photovoltaic power generation. It is composed of two pieces of glass and solar cells. , Collected in parallel to the lead end to form a photovoltaic cell assembly, the photovoltaic cell assembly is the core part of the solar power generation system, and is also the most important part of the solar power generation system. Its function is to convert solar energy into electrical energy, or to store it in the battery Or push the load to work, in order to effectively improve the efficiency of the components, take the measure of coating the back glass with a white reflective coating; [0...
