Abstract

The invention discloses an environment-friendly heat reflection coating and a preparation method thereof.The environment-friendly heat reflection coating is prepared from, by weight, 20-45 parts of silicon dioxide, 22-40 parts of rutile type titanium dioxide, 20-40 parts of acrylic resin, 18-36 parts of epoxy resin, 8-25 parts of aedelforsite, 3-10 parts of sodium borate, 8-20 parts of zinc oxide, 5-12 parts of ground calcium carbonate, 13-25 parts of negative oxygen ion powder, 12-26 parts of bamboo charcoal powder, 6-13 parts of a wetting agent, 7-12 parts of a defoaming agent, 7-15 parts of a levelling agent, 9-13 parts of a film forming auxiliary and 35-60 parts of water.According to the environment-friendly heat reflection coating and the preparation method thereof, a coating base material is prepared by compounding the acrylic resin and the epoxy resin, rutile type titanium dioxide, silicon dioxide and the like are taken as the basic components of packing, the negative oxygen ion powder and the bamboo charcoal powder are added, and therefore the heat reflection performance of the packing is improved; in addition, the heat reflection coating which is environmentally friendly and good in heat reflection effect is prepared through the synergistic effect among all the components.

Description

technical field [0001] The invention relates to the field of indoor wall coatings, in particular to an environmentally friendly heat-reflecting coating and a preparation method thereof. Background technique [0002] Heat reflective coating is a brand-new thermal insulation material, which is made by selecting high-performance resin, high-reflection and high-radiation particles and fillers; it uses a high-emission and high-reflection particle structure to reflect electromagnetic wave energy. It is isolated from the outside of the building, and the high-reflectivity coating is used to reflect the indoor heat radiation to achieve the purpose of heat insulation. And reflect the heat energy before the wall absorbs the heat energy, and at the same time, most of the heat energy entering the coating is radiated into the air, which fundamentally solves the problem of heat preservation and insulation. [0003] Heat-reflective coatings are mainly divided into three types: composite fo...
