水性UV固化含氟丙烯酸酯涂料的制备及性能研究

摘要

A novel UV-curable waterborne fluorinated acrylate resin have been synthesized from 1 H,1H,2H,2H-perfluorooctyl methacrylate,methacrylic acid,hydroxyethyl methacrylate,n-butyl acrylate and toluene diisocyanate via a three-step reaction process.The chemical structure and thermal performance of fluorinated acrylate was characterized by FTIR,PCS,TG and DTG.The PCS results showed that latex could get a good particle size distribution and stability when the content of MAA was 6％ ;the TG and DTG results showed that the thermal performance of fluorine modified acrylate resin was significantly improved.%以甲基丙烯酸十三氟辛酯、甲基丙烯酸、甲基丙烯酸羟乙酯、丙烯酸丁酯和2,4-甲苯二异氰酸酯为原料,通过三步反应合成了一种新型的水性可光固化含氟丙烯酸酯树脂.利用FT-IR、PCS、TG、TGA等分析测试手段对树脂的结构及热性能进行了研究.PCS分析结果表明:当甲基丙烯酸含量达到6％时,乳液可以获得良好的粒径分布及稳定性.TG和DTG分析结果表明:氟改性的丙烯酸酯树脂的热性能得到显著的提高.
