Inorganic waterproof flame-retardant coating and preparation method thereof

The invention discloses an inorganic water-resistant flame-retardant material and a preparation method thereof. The inorganic water-resistant flame-retardant material is mainly prepared from water, phosphate, lithium water glass, a magnesium-containing compound, modified silicon dioxide, jade powder, kaolin, coarse whiting, a dispersing agent, a thickening agent and a defoaming agent. Wherein the lithium water glass is a main film-forming substance and is combined with the modified silicon dioxide, the magnesium-containing compound and other raw materials to act together, so that the water resistance and the scouring resistance of the coating are effectively improved. After the surface of a wall body or a building material is coated with the coating, the wall body or the building material has better high temperature resistance, waterproof performance, fireproof performance and the like. The preparation method is simple, and the prepared inorganic water-resistant flame-retardant material can reduce coating dam
