NOVELTY - A solar reflective coating comprises 20-40 pts. wt. fluororesin, 3-8 pts. wt. isocyanate, 0.5-2 pts. wt. dispersant, 10-30 pts. wt. titania, 10-30 pts. wt. magnesium oxide, 1-3 pts. wt. graphene, 0.1-0.5 pt. wt. silane coupling agent, 1-5 pts. wt. nano composite powder, 1-2 pts. wt. silica, and 10-20 pts. wt. butyl acetate. USE - Reflective coating is used for solar photovoltaic assembly back plate. ADVANTAGE - The solar reflective coating has high reflectivity to solar light, and excellent weather resistance, water resistance, and UV resistance, stability, and can be prepared industrially by a simple method with low device requirement. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for solar reflective coating, which involves stirring fluororesin, dispersant, silane coupling agent, and 50% butyl acetate for 30 minutes to obtain mixture (A), adding titania, magnesium oxide, graphene, and nano composite powder to mixture (A), stirring for 40 minutes to obtain mixture (B), grinding and dispersing to a fineness of 5-8 microns, grinding mixture (B) to obtain mixture (C), slowly adding 50% butyl acetate and isocyanate to mixture (C), stirring for 40 minutes, filtering the obtained paint using 500-mesh filter, and sealing in a container.
