[中文文摘]研究了可作为紫外光固化涂料和油墨等产品的基体树脂的改性环氧大豆油树脂的合成及表征.利用环氧大豆油的环氧环的化学活性,先后与丙烯酸和马来酸酐进行反应,分别合成了油溶性环氧大豆油丙烯酸酯(AESO)和水溶性的马来酸改性环氧大豆油树脂(MAESO).并用红外和核磁对两种产物的结构进行了表征.添加紫外光引发剂后,两种产物在紫外光照射下均可快速固化.合成AESO最佳条件为环氧大豆油:丙烯酸=1.2:1(摩尔比),催化剂三苯基膦的用量为总质量的1%,反应温度为120℃;合成MAESO最佳条件为AESO:马来酸酐=4:1(摩尔比),催化剂钛酸正丁酯用量为1%,反应温度90℃.[英文文摘]In this paper,two kinds of basal resins,the modified epoxidized soybean oil oligomers,for UV-cured coatings and inks were studied.The epoxidized soybean oil(ESO) was modified by acrylic acid(AA) and maleic anhydride(MA).As a result,oil-soluble acrylated epoxidized soybean oil(AESO) and water-soluble maleinated acrylated epoxidized soybean oil(MAESO) were gained respectively.The resulting products were characterized by FTIR and 1H-NMR.With the addition of UV initiator,these two products could be cured in a short time under the UV light. The suitable conditions of the synthesis of these two oligomers have been discussed. For AESO, the best reaction conditions are ESO: AA= 1. 2: 1( by mol. ) , the mount of the catalyst Ph3P is 1%, reaction temperature is 120 ℃; for MAESO the best reaction conditions are AESO: MA= 4: 1( by mol.) ,the mount of the catalyst tetrabutyl titanate is 1%, reaction temperature is 90℃.
