Title: One-side finished metallic sheet and laminated sheet using the same metallic sheet
Inventor: MATSUMOTO MOTOO
IPC: B32B15/04
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To obtain a one-side finished metallic sheet small in warpage and excellent in the adhesive durability of the back side by subjecting the back side of a metallic sheet as the base metal subjected to one-side finishing treatment to Z-S treatment. SOLUTION: For example, on the back side of a steel sheet subjected to porcelain enameling finish, zinc-iron base alloy grains are projected to form dry alloy coating film, and this alloy coating film is subjected to chemical conversion treatment such as chromating treatment. By the elongation of the steel sheet by the mechanical projection of the zinc-iron base alloy grains, the back side is elongated to relax its warpage, and, in the case it is used in the shape of single substance, the back side is also excellent in corrosion resistance. Moreover, in the case it is used in the shape of a laminated sheet by pasting the back side with a backup material, the improvement of adhesiveness is added to the relaxation of the warpage, so that it also shows excellent adhesive durability to the backup material.  Thus, even in the case it is used in a reversely warping state such as an interior finishing plate in a tunnel, its peeling can be prevented over a long period.
