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.

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 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 CaCO3 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.

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