The invention relates to a manufacturing method of an aluminum plate decorative picture. The manufacturing method comprises the steps of selecting an aluminum plate, preparing a transitional glaze layer, mixing and stirring, spraying the transitional glaze layer, primary firing, spraying a surface glaze layer, secondary firing, cooling and the like. The method is reasonable and feasible, the transitional glaze layer, the aluminum plate and the surface glaze layer are combined closely, a fired product is attractive and elegant, the surface of a print is flat and does not wrinkle, the fired product is firm and durable, and can be stored for a long time, and the technical problems that jet drawing cloth of a decorative picture of an exterior wall of a building easily fades and drops, is shortin service life, and cannot be stored for a long time, the time and cost are wasted if the jet drawing cloth is changed, the cost is increased, an oxidation film of the surface of the aluminum plateis not easily combined to the glaze layer directly, coloring of the glaze layer of the surface is affected, during firing, the aluminum plate is quite easily melted, and cannot be glazed, if the aluminum plate is cooled suddenly after being fired, arched deformation of the surface of the aluminum plate is easily caused, the quality of products is affected, the production benefit of enterprises isalso affected and the like are solved. Compared with the prior art, the manufacturing method of the aluminum plate decorative picture has good market prospect and development space.
