Inorganic insulation coating for large dam surface, and preparation method thereof

The present invention discloses an inorganic insulation coating for a large dam surface, and a preparation method. The preparation method comprises: according to the mass parts, preparing a solution from an alkali and water, and cooling to a room temperature; pouring the weighed water glass to the solution, adding industrial waste materials, uniformly dispersing; after carrying out a complete reaction, adding a nano-metal oxide material, a surfactant and an inorganic additive, uniformly dispersing to prepare an inorganic polymer matrix material; mixing the prepared inorganic polymer matrix material and hollow glass micro-beads according to the mass ratio, uniformly dispersing to prepare the inorganic insulation coating for the large dam surface. According to the present invention, the prepared inorganic insulation coating of the present invention has good insulation function, can be used only by brushing construction; the post maintenance is easy; the appearance of the large dam is not affected; with the inorganic insulation coating for the large dam surface, the requirements of the large dam surface insulation and the large dam surface protection are met, and the prepared coatingcan be adopted as the insulation coating for the civilian building external walls.
