Problems solved by technology

[0002] At present, the reflective heat-insulating coatings applied to building facades are mainly thin-coated, such as reflective heat-insulating latex paint; there are also a few that use reflective heat-insulating materials to add real stone paint slurry to make reflective heat-insulating thick paste Paint, that is, reflective and heat-insulating real stone paint or texture paint, but the thick-build paint made by this method has an unsatisfactory reflective and heat-insulating effect, and the construction effect is not easy to grasp, and it is easy to fade and lose color

Abstract

The invention discloses reflective thermal-insulating sand and a preparation method thereof and belongs to the technical field of coating preparation. The sand comprises the following components in parts by weight: 80-90 parts of quartz sand, 40-60 parts of an emulsion, 20-40 parts of reflective thermal-insulating titanium dioxide, 20-30 parts of a functional filler, 0.1-1 part of a dispersion wetting agent, 5-10 parts of a film formation aid, 2-5 parts of other aids, 1-1.5 parts of a Ph value adjusting agent, 1-1.5 parts of a toner and 10-20 parts of deionized water. The sand has the characteristics of being excellent in reflective thermal-insulating effect, high in sunshine reflection rate and hemispherical emission rate, dense in coating film, smooth in surface, green and environment-friendly, free of VOC (volatile organic compound), free of industrial waste, good in heat preservation and dirt resistance, good in weather resistance, excellent in thermal insulation and long-lasting in thermal insulation; a color modulation process is simple, equipment requirements are low, the cost is low, and the raw material cost is low as water is adopted as a solvent.
