Abstract

The invention discloses a solar reflective coating. The solar reflective coating is prepared from the following raw materials in parts by weight: 20 to 40 parts of fluorine resin, 3 to 8 parts of isocyanate, 0.5 to 2 parts of dispersant, 10 to 30 parts of titanium dioxide, 10 to 30 parts of magnesium oxide, 1 to 3 parts of graphene, 0.1 to 0.5 part of silane coupling agent, 1 to 5 parts of nanometer composite powder, 1 to 2 parts of silicon dioxide and 10 to 20 parts of n-butyl acetate. The coating provided by the invention has high reflectivity to sunlight and good weatherability and water resistance. Coatings prepared by using the coating have high reflectivity, high ultraviolet light resistance and high stability, and are particularly suitable for the coating used for backplane of a solar photovoltaic module. In addition, the preparation process of the invention is simple, the requirements of equipment are low, and the industrial production is easy.

Description

technical field [0001] The technical field of solar photovoltaic backplane, specifically a solar reflective coating. Background technique [0002] As the environmental protection problems caused by traditional energy power generation become increasingly prominent, solar energy, as an inexhaustible clean energy, has been paid more and more attention by people. With the continuous breakthrough of solar cell technology, solar photovoltaic power generation is becoming more and more mature and popular. As an important packaging material for components, solar photovoltaic backsheets are used to encapsulate solar cells, and solar reflective coatings endow solar backsheets with high reflective performance on the basis of traditional packaging functions, thus effectively improving the sunlight penetration through components. The reflectivity of the battery behind the backsheet improves the power generation efficiency of the solar module. [0003] As a functional coating, solar refl...
