In this paper, acrylated epoxidized soybean oil( AESO) was synthesized by self-made epoxidized soybean oil. And then acrylated epoxidized soybean oil was grafted respectively by maleic anhydride and hydroxyethyl acrylate half blocked isophorone diisocyanate to abtain MAESO and HAESO. And the structures of intermediate products were characterized by FT-IR. UV curing system was formed by adding 20%styrene and 3% IRG-184 into the oligomer. The UV cured resins were well coated on the surface of tinplate and polytetrafluoroethylene plate,and then cured under UV irradiation. The properties of the films were characterized by tensile test,scanning electron microscope( SEM) and thermal gravimetric analysis( TG). And water absorption, gel content, impact strength, adhesion test, gloss and pencil hardness were also demonstrated. The results showed that the UV cured film made by maleic anhydride grafting acrylated epoxidized soybean oil present more excellent comprehensive properties.
