Problems solved by technology

[0003] The key to the preparation process of the transparent network backsheet is the photovoltaic coating that forms the grid. The photovoltaic coating needs to have ultra-high reflectivity, and it also needs to meet electrical insulation, moisture resistance and weather resistance. At present, there is no good coating

Abstract

The invention relates to the technical field of photovoltaic coatings, in particular to a high-reflection photovoltaic coating and a preparation method thereof. Comprising the following components in parts by mass: 20-35 parts of resin; 25 to 35 parts of fluorocarbon resin and 10 to 15 parts of high-reflection microspheres; 15-25 parts of an inorganic pigment; 5-8 parts of a curing agent; and 1-3 parts of an auxiliary agent. According to the invention, the glass powder and the TiO2 are prepared into the microspheres with the reflection shell through the high-reflection microspheres, so that the glass powder can be more dispersed, and the reflection capability is improved.

Description

technical field [0001] The invention relates to a high-reflection photovoltaic coating, in particular to a high-reflection photovoltaic coating and a preparation method thereof. Background technique [0002] Bifacial power generation is a recognized industry development trend. According to the forecast of research institutions, bifacial modules will occupy more than 40% of the market share by 2027. Traditional double-sided modules still use double-sided glass as the main packaging material. Double-glass modules not only have problems such as difficult process and low yield rate, but also have problems such as heavy weight, difficult installation, and high damage rate, which limit the development of double-glass modules to a certain extent. Transparent backplane components can also achieve double-sided power generation, and they are also characterized by light weight, easy installation and transportation, high production process compatibility, and high process yield, which m...
