TWO-LAYER COMPOSITE RESIN COATED FILM PRECOATED METAL PLATE WITH EXCELLENT DRAWING PROPERTIES

摘要

PROBLEM TO BE SOLVED: To provide a precoated metal plate suitable for drawing for generating a strain of tension and compression at a metal plate. ;SOLUTION: The resin coated film precoated metal plate comprises a resin coated film having different mechanical characteristics and laminated on the plate. In this case, the laminated coated film has 100MPa or more of tensile elastic modulus of a tensile test value of the state that the laminated film is laminated, a yield point, and an elongation at break of 10% or more. The resin coated film having as a single layer a tensile test value of elastic modulus of 5 to 800MPa as a tensile test value, a strength at break of 50MPa or less and an elongation at break of 30% or more, and the resin coated film having as a single layer a tensile test value of 300 to 3000MPa of tensile elastic modulus, a strength at break of 10MPa or more are preferably laminated.;COPYRIGHT: (C)1998,JPO
