Embodiment 1

[0028] A method for manufacturing a stone pattern color-coated aluminum plate, the process of the method is:

[0029] a. Carry out pretreatment processing on the aluminum plate. The pretreatment processing of the aluminum plate includes cleaning with alkaline water and acid water to realize degreasing processing, and adopting surface chromization processing to form a passivation film layer to realize passivation processing. After the pretreatment processing The aluminum plate is uncoiled;

[0030] b. Coating a primer on the surface of the pretreated aluminum plate, the primer is polyurethane paint, baked in an oven to form a primer, and then rewinding the aluminum plate with the primer , wherein the oven is divided into four zones, and the aluminum plate coated with primer is baked sequentially, the temperature of the first zone is 240°C, the temperature of the second zone is 260°C, and the temperature of the third zone is 280°C , the temperature in the fourth zone is 260°C; ...

Abstract

The invention discloses a manufacture method for a stone pattern color-coating aluminum plate. The method comprises the process of performing pretreatment processing on the aluminum plate, coating a bottom-layer coating on the surface of the pretreated aluminum plate, baking the bottom-layer coating in an oven so as to form a bottom coating layer; coating a first middle-layer coating on the bottom coating layer, baking the first middle-layer coating in the oven to form a first middle coating; coating a second middle-layer coating on the first middle-layer coating, baking the second middle-layer coating in the oven to form a second middle coating; coating a face-layer coating on the second middle-layer coating, baking the face-layer coating in the oven to form a face coating; finishing coating the stone pattern color coating aluminum plate, and rolling the coated aluminum plate. By means of the method, the stone pattern color-coating aluminum plate is provided with stone patterns, the coatings are coated and are baked by the high temperature oven for multiple times, the coatings are not easy to falling off and embrittlement, is good in adhesive force and performance of gloss, flexibility, impact resistance, weather resistance and the like.

Description

technical field [0001] The invention relates to the field of aluminum sheet manufacturing, in particular to a method for manufacturing a stone pattern color-coated aluminum sheet. Background technique [0002] All kinds of aluminum plates are usually used in the decorative materials of buildings and the decorative materials of furniture, home appliances, method products, consumer electronics and signs. Some of them are coated with a layer of single-color coating on the aluminum substrate, but the color is single and dull, without patterns, which cannot satisfy people's pursuit of fashion; some are on the aluminum substrate, covered with a layer of PVC with patterns. Film or use ink to transfer a layer of patterns, but the pattern layer is easy to fall off, brittle, poor weather resistance, blurred texture, false graphics, so it cannot be used outdoors. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a metho...
