Mix the selected monomers and oligomers to achieve the desired viscosity and reactivity. 2. Add a photoinitiator to the mixture in an appropriate concentration to facilitate UV curing. 3. Introduce functional groups such as quaternary ammonium salts into the polymer backbone by selecting suitable reagents and controlling the reaction conditions. 4. Place the mixture in a UV curing chamber and expose it to UV light for a specified duration to initiate the polymerization process. 5. After curing, the resulting resin can be characterized for its hydrophilicity and functional properties.本发明涉及一种季铵盐型亲水性紫外光固化树脂的制备方法该涂料的主体亲水性树脂是由可聚合非离子表面活性剂烯丙氧基壬基苯氧基丙醇聚氧乙烯醚、丙烯酸酯及丙烯酸经自由基聚合得到侧链含有羧基的聚丙烯酸酯，然后侧链羧基进行开环甲基丙烯酸缩水甘油酯的环氧基而得到侧链含有双键的光固化亲水性聚丙烯酸酯。将二元聚醚胺与丙烯酰氧乙基三甲基氯化铵在室温下进行迈克尔加成反应，得到双末端仲氨基化合物中间体；将所述双末端仲氨基化合物中间体与多官能度丙烯酸酯在 40到45摄氏度 下进行迈克尔加成反应，得到季铵盐型亲水性紫外光固化树脂。在配有机械搅拌、温度计、氮气导入装置的250毫升四口瓶中，加入乙醇(70克)，阻聚剂对羟基苯甲醚(0.14克)，聚醚胺D400(2.30克，5mmol)和80%丙烯酰氧乙基三甲基氯化铵水溶液(24.2克，10mmol)，室温反应1.5小时，FT-IR检测不到810cm^{-1}处双键的吸收峰，第一步反应结束。然后加入乙氧基双季戊四醇六丙烯酸酯(EO96mol)(48.02克，10mmol)，升温至45°C反应3小时，FT-IR检测不到3400{-}3300cm^{-1}处仲胺的吸收峰，结束反应，得到浅黄色透明液体。然后用正己烷进行沉淀，再经50°C真空干燥12小时得到官能度为10的季铵盐型亲水性紫外光固化树脂。"
