Abstract

In order to produce the steel sheet with lubricating film by UV (ultraviolet)-curing process, the composition of UV-paint; and the condition of UV-curing have been studied.
The UV-paint is composed of an acryl-oligomer having carboxyl groups and one functional double-bond, monomer, photoinitiator and lubricant. The weight ratio of these components is 80:20:5:10. The acid value val of the UV-paint is 100. Line speed of sample for curing is 15 m min per an UV-lamp (O3 type, 80 W/cm). The steel sheet with lubricating film, whose thickness is 2.5±0.5 μm, is excellent in drawability, resisitibility against galling, alkali-removabilit and rust preventability.
