摘要 用一缩二乙二醇与E-44环氧树脂反应,得到的改性环氧树脂再与丙烯酸反应,制备了适于配制竹木基涂饰的紫外光固化的改性环氧丙烯酸酯预聚物.讨论了催化剂种类对环氧树脂转化率及产物粘度的影响,催化剂用量对改性环氧树脂丙烯酸酯化的影响,及光引发剂种类对固化速度的影响.最终制得的改性环氧丙烯酸酯光固化涂料比改性前的性能良好. Modifed epoxy was synthesizrd by reacting diglycol aldehyde with E-44 epoxy resin, then UV-curable epoxy acrylated prepolymer used for coating bamboo and wood was synthesized by reacting modifed epoxy with acrylic acid. The effects of synthesis condition ,such as the kind and dosage of catalyst and reaction temperature etc. have been discussed. The effect of the kind of catalyst on the epoxy yield and producUs viscosity,and the effect of the dosage on the esterifying of epoxy were discussed. The effect of the kind of photoinitiator on the curing speed was also discussed. And the final modifed epoxy acrylate UV-curing coating's property was better than the coating without modify.
