Decorative stainless steel rolled sheet with embossed patterns and method of manufacturing the same
First Claim
1. A method of manufacturing a decorative stainless steel rolled sheet having an embossed pattern, comprising:
- unwinding a thin stainless steel sheet having a thickness of 0.05˜
0.15 mm and subjected to surface treatment including nanoceramic coating or PVD (Physical Vapor Deposition) ionic coating from a thin stainless steel sheet take-up roll and feeding it between first feed rolls;
applying a hot melt adhesive on one side of the thin stainless steel sheet, which moves by means of the first feed rolls, using an adhesive feed roll and the first feed rolls, thus forming a hot melt adhesive layer on one side of the thin stainless steel sheet;
unwinding a release sheet having a thickness of 0.05˜
0.10 mm and made of a polyethylene or polypropylene film from a release sheet take-up roll and feeding it between second feed rolls so that it is bonded onto the hot melt adhesive layer formed on one side of the thin stainless steel sheet;
embossing the thin stainless steel sheet and the release sheet bonded thereto by means of the hot melt adhesive layer using an emboss roll composed of a positive pattern roll and a smooth roll, thus forming the embossed pattern; and
winding a resulting product in rolled sheet form on a take-up roll.

Abstract
A decorative stainless steel rolled sheet has an embossed pattern, suitable for use as a surface finish or an interior surface finish of products, wherein a thin stainless steel sheet subjected to surface treatment including nanoceramic coating or PVD ionic coating resulting in various colors and a release sheet alone or with a nonwoven fabric layer bonded thereto by means of a hot melt adhesive layer are embossed together and bonded to each other with the embossed pattern, thus exhibiting superior bonding strength, heat resistance, fire resistance, scratch resistance, shape stability, flexibility and wrinkling resistance. In the method of manufacturing such a decorative stainless steel rolled sheet, the rolled sheet can be mass produced at uniform quality using a continuous process.
