Title:
COATED METAL PLATE WHEREIN PROCESSABILITY IS UNCHANGED WITH PASSAGE OF TIME AND MANUFACTURE OF THE SAME
Document Type and Number:
Japanese Patent JP3213784
Kind Code:
B2
Abstract:
PURPOSE: To provide a coated metal plate having a coating film containing an organic resin the processability of which does not deteriorate with the passage of time.
CONSTITUTION: In a film of a coated metal plate, 95wt.% or more of resin components excluding a cross-linking agent is occupied by a resin which indicates no endothermic peak in its glass transition area when the glass transition temperature is measured by differential thermal analysis after repeated operations in which the resin, after being allowed to stand at a temperature higher than the glass transition temperature, is allowed to stand at a temperature lower than the glass transition temperature and no increase in the glass transition temperature after the manufacture of the resin. It is preferable that the glass transition temperature of the film is 40°C or below and the raw metal plate is a galvanized steel plate with a plated metal quantity on one side exceeding 40g/m2. In this way, the initial processability of the plate can be kept after being stored for one year in a warehouse, indicating no deterioration with the passage of time.
