Abstract

Abstract: A photosensitive resin fills S-2-E, based on succinic acid anhydride(SAA)、2-hydroxy-4-(2-hydr-oxyethoxy) -2-methylpropiophenone (D2959) and epoxidized oleic acid (EOA),was synthesized and used for modification of CaCO₃. Compared with the CaCO₃ modified by OA, the characterization of CaCO₃modified by S-2-E、the optical activity of S-2-E-CaCO₃ and its effects on the properties of UV curing coating were studied by oil absorption value test、DPC、DMA and SEM.The results show that there are not so much differences between S-2-E and OA in modification of CaCO₃. And the CaCO₃which become photosensitive after being modified by S-2-E, can cure with UV coating and make the properties of UV curing film better in hardness and water resistance.

Key words: photosensitive, fatty acid, surface modification, CaCO₃, UV curable coating
