Abstract

The invention relates to coating materials for reflecting and insulating light and heat, particularly relates to floating beads and a method for preparing modified floating beads and belongs to the technical field of architectural coatings. A reflective and insulating coating material comprises a reflective coating material and the modified floating beads, wherein the modified floating beads are uniformly dispersed into the reflective coating material. According to the floating beads and the method for preparing the modified floating beads, from economic considerations, ceramic hollow microbeads are replaced with flyash floating beads, then, a good technical effect is obtained; the price of the flyash floating beads is far lower than that of the ceramic hollow microbeads, and although the heat insulating capability of the flyash floating beads is strong, the color of the flyash floating beads is not white enough, thus, the light and heat reflecting properties of the coating material are affected; the color problem of the floating beads is solved by adopting a titanium white spraying process, and the wall adhesion of the floating beads is far greater than that of the ceramic hollow microbeads, so that the floating beads have technical advantages; the reflective coating material can be used separately, can also be used in a manner of being matched with the modified floating beads, has a light and heat reflecting effect during separate use and has a heat reflecting and insulating effect during matched use.

Description

technical field [0001] The invention relates to a coating for reflecting light and heat and isolating light and heat, in particular to a preparation method of modified floating beads and the floating beads, which belong 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 p...
