Problems solved by technology

[0003] Conventional finishing layers with better texture include glazed layers, paints, etc. The glazed layer presents a beautiful and generous effect, which is a high-grade decorative layer, but conventional glazes must be sintered at high temperatures (>800°C). Considering Photovoltaic modules are difficult to withstand such high temperatures, therefore, conventional glazes are difficult to apply to photovoltaic modules
Patent application CN201210132874 discloses a glaze that can be cured at room temperature, but the formula of this glaze contains a large amount of organic substances, and these organic substances have poor chemical stability, and the organic structure is destroyed in a humid or light environment , the glaze layer may produce discoloration and chalking, reducing the service life

Abstract

The invention belongs to the technical field of photovoltaic building integration, and relates to a decorative surface layer material, a photovoltaic building material and a preparation method thereof. Said a facing layer material, in terms of weight ratio, the raw materials of said facing layer material include 1-6 parts of inorganic pigment, 20-40 parts of silica sol, 10-25 parts of spinel powder, 12-20 parts of kaolin powder 20-30 parts of red garnet powder, 3-8 parts of talcum powder, 2-8 parts of lime powder and 15-40 parts of water. The slurry prepared by the invention is all inorganic matter, has good weather resistance, strong adhesion to the solar cell layer, has the advantages of no falling off, no cracking, etc., and can be used outdoors for many years.

Description

technical field [0001] The invention relates to the technical field of photovoltaic building integration, in particular to a facing layer material, a photovoltaic building material and a preparation method thereof. Background technique [0002] At present, places where people use new energy, including wind energy, solar energy, and ocean energy, are located in suburbs, deserts, or oceans that are far away from people's activities, and are rarely seen in cities with high population density and high energy consumption. new energy. Based on the wide distribution of solar energy, if the layout is reasonable, it is possible to use solar energy on a large scale in cities. An important method that can be adopted is Building Integrated Photovoltaics (BIPV). However, the photovoltaic modules used in conventional BIPV are generally dark blue, gray, and black. Aesthetic requirements; In addition, BIPV photovoltaic modules are generally placed on the roof or placed on the curtain wall...
