摘　　要：本文以丁二酸酐(SAA)、2-羟基-4-(2-羟基乙氧基)-2-甲基苯丙酮(D2959)和环氧油酸(EOA)为原料,合成了一种具有感光性的脂肪酸S-2-E,并用于碳酸钙的改性.然后以油酸(OA)改性碳酸钙为对比,通过吸油量测试、差动光照热分析仪(DPC)、动态力学分析(DMA)、扫描电镜(SEM)等测试手段讨论了S-2-E对碳酸钙的改性效果、相应改性碳酸钙S-2-E-CaCO3的光活性及S-2-E-CaCO3对UV涂料的性能影响.结果显示,S-2-E对碳酸钙的改性效果与OA相当.碳酸钙经S-2-E改性后具有一定的光活性,能参与UV涂料的固化,固化膜的硬度、耐水性等性能有所改善.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 CaCOa. Compared with the CaCOa modified by OA, the characterization of CaCO3 modified 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 CaCOa which 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.
