Embodiment 1

[0028] A preparation method for a colored stainless steel plate, comprising the steps of:

[0029] (1) Alkali cleaning: use 201 / 306 stainless steel coils as the base plate, soak the stainless steel coils in lye, and the soaking time can be adjusted according to the actual production speed of stainless steel coils;

[0030] (2) Brush roller scrubbing: place the brush roller on the surface of the stainless steel coil soaked in lye, drive the brush roller to scrub the surface of the stainless steel coil until the oil stain on the surface of the stainless steel coil is completely removed, and then soak and clean it with clean water for 3 times ;During the brush cleaning process, water can be continuously replenished and water circulation can be used to avoid reducing the cleaning effect and generating more foam due to the accumulation of oil stains;

[0031] (3) Coating film-forming agent: place the stainless steel coil after washing with clean water in a squeeze dryer, squeeze ou...

Abstract

The invention discloses a preparation method of a colored stainless steel plate. The preparation method comprises the following steps that a stainless steel coiled material is immersed in alkali liquor; a brush roller is driven to scrub the surface of the stainless steel coiled material, and the stainless steel coiled material is subjected to clear water soak cleaning for 3 times; the moisture ofthe stainless steel coiled material is squeezed, the stainless steel coiled material is dried at 180 DEG C-220 DEG C, and a film-forming agent is squeezed and subjected to coating; drying is performedat 220 DEG C-250 DEG C, roller coating of undercoat is performed, drying is performed at 200 DEG C- 220 DEG C, and water cooling is performed; roller coating of topcoat is performed, drying is performed at 220 DEG C-240 DEG C, the total coating amount of the undercoat and the topcoat is 15[mu]m-22[mu]m, and water cooling is performed; and after a looper is stored, shear winding and forming are performed to obtain the colored stainless steel plate. The preparation method realizes the uniformity of coloring, high temperature resistance, wear resistance and other characteristics of colored stainless steel products by the steps such as alkali liquid washing, film forming agent coating and undercoat and topcoat coating and setting of the related parameters; and the preparation method is simpleand the cost is low.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing of stainless steel materials, in particular to a method for preparing colored stainless steel plates. Background technique [0002] Stainless steel materials are resistant to weak corrosive media such as air, steam, water, or stainless steel. With the continuous expansion of the demand for stainless steel, colored stainless steel has gradually developed, and the coloring technology of stainless steel has been more widely used. Colorful colors not only increase the decoration and artistry of stainless steel, but also improve the corrosion resistance and wear resistance of stainless steel. The most commonly used colored stainless steel products are colored films on the surface of stainless steel materials, but when the temperature exceeds 200 ° C, the color film It may be oxidized or dehydrated, and it will become easy to fall off, and the corrosion resistance will be greatly re...
