Abstract

The invention relates to a colored solar heat reflective cooling coating and a preparation method thereof. By using a waterborne acrylic emulsion as a film forming base material, the coating is good in anti-aging performance, long in outdoor service life, non-toxic and environmental friendly, has excellent resistance to stains, alkali resistance and water resistance and has a good adhesive force to base materials such as concrete, metals, woods and glass. By adding color functional auxiliaries with strong near infrared reflection or transmissivity supplemented by various extender pigments and auxiliaries, the coating is simple to prepare, low in cost and environmentally friendly. Compared with common colored coatings, the colored solar heat reflective cooling coating has better near infrared reflection or transmissivity, thereby satisfying the latest requirements on industrial standard of building industry. In winter, the coating can be used for remarkably improving the surface and inner temperatures of a coated object such as concrete, metals and woods, can be widely applied to building roofs and exterior walls and further has ideal energy-saving and cooling effects while being used for beautifying the coated building.

Description

technical field [0001] The invention relates to a colored solar heat reflective cooling paint and a preparation method thereof, in particular to a colored solar heat reflective cooling paint with water-based acrylic emulsion as a film-forming base material and a preparation method thereof. Background technique [0002] White solar heat reflective cooling coating has high solar heat reflectivity, high heat generation rate and low absorption rate, and has excellent cooling performance. White solar heat reflective cooling paint is used on the wall, which can greatly reduce the building's cooling energy consumption in summer. It is more suitable for flat roofs or sloping roofs with small slopes. However, for sloping roofs and facades with large slopes, although white paint has the best cooling effect, from an aesthetic point of view and visual comfort, colored walls and roofs are preferred. Currently, colored solar heat The market demand for reflective cooling coatings is far ...
