The invention relates to an aerogel paint and a preparation method. It is characterized in that the raw material components and the weight parts of each component are respectively: 10-20 parts of aqueous solution, 15-30 parts of silane coupling agent, 10-20 parts of dimethyl silicone oil, 40-60 parts of silica aerogel , 10-20 parts of stabilizer, 5-10 parts of aluminum oxide, 5-10 parts of titanium dioxide, 10-20 parts of calcium carbonate, 10-20 parts of organic binder, and 5-10 parts of dispersant. In the invention, the aerogel coating is prepared by using the silica aerogel as the main raw material and the organic binder and other raw materials, and they have a synergistic effect, which can effectively improve the dispersibility of the aerogel in the coating, thereby improving the aerogel The uniformity of the gel coating improves the film-forming quality of the coating. At the same time, the aerogel coating prepared by the invention has fast curing speed, excellent water resistance, high hardness, good coating adhesion, good wear resistance, good thermal insulation performance, and has the advantages of simple process, low cost, no It is toxic and environmentally friendly and has no negative impact on human health. |
