Description

technical field [0001] The invention relates to the field of coatings, in particular to a high ultraviolet reflectance reflective heat-insulating coating and a preparation method thereof. Background technique [0002] In recent years, many reflective heat-insulating coatings have appeared on the market. According to relevant testing standards, such as JC / T 235-2014, the reflectivity in the wavelength range of 300-2500nm is mainly detected. In this wavelength range, the near-infrared region (780 -2500m) energy accounted for 50%, visible light region (400-780nm) energy accounted for 45%, ultraviolet light region (300-400nm) energy accounted for 5%; according to observation, ordinary reflective heat insulation coatings have extremely low reflectivity in ultraviolet light region , while the general reflective heat insulation coatings on the market only one-sidedly increase the reflectivity of its near-infrared light region, while ignoring the influence of ultraviolet light regio...
