Geopolymer-based inorganic reflective coating as well as preparation method and application thereof

The invention relates to the technical field of inorganic reflective coatings, and discloses a geopolymer-based inorganic reflective coating as well as a preparation method and application thereof, and the geopolymer-based inorganic reflective coating comprises the following components: an active material, solid water glass, sodium hydroxide, an emulsion, titanium dioxide, talcum powder, a defoaming agent, a flatting agent, a dispersing agent and phosphoric acid. The solid water glass and the active material are used as film forming substances, so that the basic mechanical property and apparent state of the coating can be adjusted; and the emulsion is doped to improve the film forming state of the coating and prevent the coating from cracking. By doping pigments and fillers, the whiteness of the coating is improved, and the reflective performance of the coating is enhanced; the geopolymer-based inorganic reflective coating provided by the invention is excellent in adhesive force and pencil hardness performanc
