Embodiment 1

[0021] A preparation process for a stainless steel paint door, comprising the following steps: a. Pretreatment: polishing the stainless steel with sandpaper, using laser planing, welding, bending, and welding angles to process it into a door shape, and finally polishing the surface of the door panel Processing, made into a fine billet, and the fine billet is subjected to secondary grinding treatment to prepare for spraying primer.

[0022] b. Spray primer: Wrap the outer surface of the pretreated door panel and its surroundings with polyvinyl chloride plastic film and perform blister and compression treatment to prepare the primary product and perform the first painting treatment, and bake it in a baking oven. The temperature in the furnace for this operation is 90°C, and the temperature in the furnace is raised to 180°C to continue baking, and the continuous baking time is 25 minutes. , c. Spray topcoat: put the above-mentioned door panels out of the oven into the oven after ...

Embodiment 2

[0026] The difference between this embodiment and above-mentioned embodiment 1 is:

[0027] In the step b, the temperature of the door panel entering the furnace is 95°C, the temperature in the furnace rises to 185°C, and the baking time is continued for 25 minutes;

[0028] In the step c, the temperature of the door panel entering the furnace is 95°C, and it is dried under the condition that the temperature in the furnace rises to 185°C, and the continuous baking time is 20 minutes;

[0029] In the step f, the above-mentioned treated door panel is put into the furnace at 95° C., and the temperature in the furnace is raised to 195° C. to continue baking for 15 minutes.

Embodiment 3

[0031] The difference between this embodiment and above-mentioned embodiment 1 is:

[0032] In the step b, the temperature of the door panel entering the furnace is 100°C, the temperature in the furnace rises to 190°C, and the baking time is continued for 25 minutes;

[0033] In the step c, the temperature of the door panel entering the furnace is 100°C, and the temperature in the furnace is raised to 190°C to continue baking, and the continuous baking time is 20 minutes;

[0034] In the step f, put the treated door panel into the furnace at 100° C., and the temperature in the furnace rises to 195° C. to continue baking for 15 minutes.

Abstract

The invention belongs to the technical field of door processing and particularly discloses a preparation technology of a stainless steel baking varnish door. The preparation technology comprises the following steps: a, pre-treating: adopting laser for gouging, carrying out welding to form a door plank, and carrying out surface polishing treatment on the door plank to manufacture a fine billet; b,spraying primer: adopting an electric paint spraying manner to spray primer on the surface of the door plank, and drying the door plank in a baking oven; c, spraying finish: spraying paint on the dried door plank once more, and drying the door plank; d, wiredrawing on lacquer: spraying black wiredrawing paint on the dried door plank, then carrying out line drawing operation on the door plank and drying the door plank; e, varnished oil spraying: spraying varnished oil on the surface of the dried door plank; and f, drying: putting the obtained door plank in the baking oven to be dried once more.The prepared stainless steel baking varnish door has the advantages of being prone to paint peeling-off, large in adhesive force, high in corrosion resistance, good in pollution prevention effect andrust prevention effect, high in glossiness and bright in color, thereby meeting the demand of a consumer for beauty.

Description

technical field [0001] The invention relates to the field of door processing, in particular to a preparation process for a stainless steel baking varnish door. Background technique [0002] Stainless steel refers to steel that is resistant to weak corrosive media such as air, steam, water, and chemically aggressive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. Stainless steel contains various alloying elements that make stainless steel have good corrosion resistance, so the resulting parts of stainless steel can maintain the integrity of engineering design for a long time, and the advantages of easy-to-process manufacturing. The design of stainless steel doors has been widely recognized, but there are also some defects in stainless steel doors. For example, the top coat of most painted stainless steel doors is easy to fall off, which affects the appearance. Contents of the invention [0003] In order to solve the lack of aesthetic...
