摘　　要：采用等物质的量的甲苯二异氰酸酯、丙烯酸-β-羟乙酯加成,得到的加成物与纳米凹凸棒表面的羟基官能团再次进行加成反应,生成表面结合双键的纳米凹凸棒中间体,然后与活性稀释剂、光引发剂、颜料、填料和其他助剂复配,制备的紫外光固化涂料具有良好的抗蚀性、耐热性、耐磨性、自洁性和环境友好性。用IR和SEM对活性体和共聚物进行了表征。Nano activated attapulgite with double bonds on surface is obtained by the addition reaction of toluene diisocyanate （TDI） with β-hydroxylehtyl acrylate at first, and then reacting with hydroxy groups on the surface of nano attapulgite. The UV- curable coatings with good corrosive resistance, heat resistance, abrasive resistance, selfclearing ability and environment protection is prepared with above- mentioned nano activated attapulgite, active diluents, photo initiators, pigments, fillers and other additives. IR and SEM are used to characterize the nano activated attapulgite and copolymer prepared therewith.
