Abstract
Provided is a manufacturing method of a stainless steel sheet having etching patterns. The method includes: coating a coating composition on a stainless steel sheet to form a coating layer; and forming a matte coated film layer, having an etching effect, on the coating layer. The coating composition comprises: 10 to 30 wt % of a silane-based compound, 0.5 to 6 wt % of an organic acid, 0.1 to 3 wt % of a vanadium compound, 0.1 to 3 wt % of a magnesium compound, and a remainder of a solvent.
Claims11
A manufacturing method of a stainless steel sheet having patterns, comprising:
- coating a coating composition on a stainless steel sheet to form a coating layer;
- ejecting a coating material including i) a transparent ink or ii) a transparent ink and a matting agent onto the coating layer;
- and
- performing UV curing within 2 seconds of ejecting the coating material to form a matte coated film layer on the coating layer, the matte coated film layer including a plurality of bubbles and having a matting effect,
- wherein the coating composition comprises:
- 10 to 30 wt % of a silane-based compound, 0.5 to 6 wt % of an acid compound, 0.1 to 3 wt % of a vanadium compound, 0.1 to 3 wt % of a magnesium compound, and a remainder of a solvent,
- the acid compound is one or more selected from the group consisting of organic acid and phosphoric acid, and
- the coating layer has a thickness of 0.5 to 5 μm, and
- wherein the patterns are formed by the matting effect.
