The invention provides a preparation method of a nano silicon dioxide anti-skinning spraying coating. The method comprises the following steps: diluting nano silicon dioxide; uniformly stirring and mixing the nano silicon dioxide with cation exchange resins; neutralizing; regulating to be alkali; and heating and bottling. By using the preparation method, under a difficult construction condition, castable materials in a rotary kiln can be repaired and coated, so that the spraying coating is high in anti-skinning performance and high in thermal shock resistance performance.
