A kind of production method of single-glazed aluminum plate decorative painting

Abstract

The invention relates to a fabrication method for a single-glaze-layer aluminum plate decoration painting. The fabrication method comprises the steps of aluminum plate selecting, glaze-layer preparing, mixing and stirring, glaze-layer spraying, high-definition printing, direct firing, cooling and temperature reducing and the like. The fabrication method is reasonable and feasible and ingenious indesign, single-glaze-layer glazing and molding at a time is adopted, secondary glazing is not needed, the production cost and time are saved, a glaze layer and an aluminum plate are combined closely,fired products are attractive, the surface of the plate painting is smooth and does not wrinkle, is sturdy and durable and can be preserved permanently, and the problem existing in the existing aluminum enamel painting fabrication process that the aluminum plate is difficult to be combined with the surface glaze layer closely is solved; and some factories use double glaze layers to be combined with the aluminum plate, the technical problems that the weight is increased to affect transportation due to the thickness of the glaze layer is too thick, when the aluminum plate is fired, the time is not mastered well, the temperature drops suddenly after firing, aluminum plate surface arch deformation is prone to being caused, the product quality and the enterprise production benefit are affected,and the like exist, and compared with the prior art, the fabrication method for the single-glaze-layer aluminum plate decoration painting has quite good market prospects and development space.

Description

technical field [0001] The invention relates to the technical field of metal enamel, in particular to a method for making a decorative painting on a single-glazed aluminum plate. Background technique [0002] Enamel is an inorganic glass enamel coated and fired on the surface of a metal base. Enamel coating on the metal surface can prevent the metal from rusting, so that the metal will not form an oxide layer on the surface when it is heated and can resist the erosion of various liquids. Enamel products are not only safe and non-toxic, but also easy to wash and clean. They can be widely used as eating utensils and washing utensils in daily life, and under certain conditions, enamel coating on the metal body exhibits high hardness and high temperature resistance. Excellent properties such as wear resistance and insulation make enamel products have a wider range of uses. The enamel layer can also give the product a beautiful appearance and decorate people's lives. It can be...

Problems solved by technology

[0005] In order to solve the existing dense oxide film on the surface of the aluminum plate in the production process of the existing aluminum plate enamel painting, it is difficult for the aluminum plate to be closely combined with the surface glaze layer without treatment; some factories use double glaze layers to combine with the aluminum plate, Excessive thickness of the glaze layer leads to increased weight and affects transportation. When the aluminum plate is fired, the timing is not well grasped, and the temperature suddenly drops after firing, which may easily lead to arching and deformation of the aluminum plate surface, affecting product quality and enterprise production efficiency. The present invention provides A method for making a decorative painting on a single-glazed aluminum plate. The method is reasonable and feasible, and the design is ingenious. The single-glazed layer is used for one-time glazing and forming without secondary glazing, which saves production costs and production time. The glaze layer and the aluminum plate are closely combined. , the fired products are beautiful and generous, the surface of the board painting is smooth and wrinkle-free, durable, and can be preserved for a long time
