Title:
PRINTED LAMINATED STEEL PLATE WITH IMPROVED CORROSION RESISTANCE
Document Type and Number:
Japanese Patent JP3069028
Kind Code:
B2
Abstract:
PURPOSE: To provide a printed polyethylene terephthalate laminated steel plate having pale color and excellent corrosion resistance.
CONSTITUTION: A laminated steel plate is obtained by forming a printed polyethylene terephthalate film, with the printed surface on the adhesive layer side, on the surface of the Z-plated steel plate via the adhesive layer, the lightness index L value of the resin layer adjacent to the Zn-plated steel plate is 70 or more after coating and drying, and silica particles having a mean particle size corresponding to 50 to 150% of the thickness of the resin layer are mixed with the resin layer by 1 to 40wt.%. The adhesive layer is provided directly on the Zn-plated steel plate or on the surface of the steel plate via thermosetting resin layer. Accordingly, the permeation and diffusion of the moisture and oxygen are expedited by the mixture of the silica, and the corrosive atmosphere of the polyethylene terephthalate film is eliminated.
