Abstract

The invention relates to a coating capable of reflecting and insulating optical heat, which belongs to the technical field of building coatings. A reflective heat-insulating coating comprises a reflective coating and modifying floating beads, wherein the modifying floating beads are uniformly dispersed in the reflective coating. According to the reflective heat-insulating coating disclosed by the invention, from economic considerations, flyash floating beads are used for replacing ceramic hollow floating beads, and good technical effects are obtained; the price of the flyash floating beads is far lower than that of the ceramic hollow floating beads; although the flyash floating beads are high in heat-insulating capacity, the colour of the flyash floating beads is not white enough and the optical heat reflecting performance of the coating is influenced, and a titanium dioxide spray-coating process is used, thus the colour problem of the floating beads is solved; and moreover, the adhesive force of the floating beads on a wall surface is far greater than that of the ceramic hollow floating beads, thus technical effects are achieved. The reflective coating disclosed by the invention can be used independently or by being matched with the modifying floating beads thereof, and has an effect of reflecting optical heat in case of being used independently and has an effect of reflective heat insulating in case of being matched with the modifying floating beads for use.

Description

technical field [0001] The invention relates to a coating for reflecting light and heat and isolating light and heat, belonging to the technical field of architectural coatings. Background technique [0002] At present, reflective heat insulation coatings have been more and more widely used in buildings. Generally speaking, under the same base material conditions, pigments and fillers play a leading role in the reflective heat insulation effect of reflective heat insulation coatings. One of the keys. Ceramic hollow microspheres are a kind of white powder. The particles are hollow inside, with low density and small thermal conductivity. They can well reflect incident waves such as light and heat, and prevent heat from being transmitted to the interior of the object. These properties make it a reflective barrier. First choice filler for thermal coatings. At present, most of the preparations of reflective heat-insulating coatings use such fillers, but high-quality cerami...
