摘要/Abstract

摘要： 以三氟化硼乙醚络合物为催化剂,以氢氧化钠为成环反应的闭环剂,利用乙二醇和环氧氯丙烷为原料合成了乙二醇二缩水甘油醚.研究了催化剂三氟化硼乙醚络合物用量、环氧氯丙烷和乙二醇摩尔比、氢氧化钠和乙二醇摩尔比,以及成环反应温度这些因素对合成反应的影响.结果表明较好的合成反应条件是:三氟化硼乙醚络合物质量分数为0.40%,环氧氯丙烷和乙二醇较佳摩尔比为2.4:1,氢氧化钠和乙二醇较佳摩尔比为2.2:1,较佳的成环反应温度为30℃.同时,把乙二醇二缩水甘油醚作为稀释剂加入到环氧树脂E-51中,利用三芳基锍鎓六氟锑酸盐作为引发剂,制备了阳离子型紫外光固化涂料,其紫外光固化膜的拉伸强度为46.25MPa,杨氏模量为1487.26MPa,断裂伸长率为6.27%.

Abstract: Ethylene glycol diglycidyl ether was synthesized with ethylene glycol and epichlorohydrin as raw materials,with boron trifluoride ether complex as the catalyst,and with sodium hydroxide as the closed ring agent of producing ring reaction.The effects of the closed ring temperature,the dosage of the catalyst,the moral ratio of epichlorohydrin to ethylene glycol,and the moral ratio of sodium hydroxide to ethylene glycol on the reaction were studied,which showed that the preferable synthesizing conditions are 0.40% of the catalyst mass fraction,the moral ratio 2.4:1 of epichlorohydrin to ethylene glycol,the moral ratio 2.2:1 of sodium hydroxide to ethylene glycol,and 30℃ of the closed ring reaction temperature.Meanwhile,the cationic type UV-curing coating was prepared with ethylene glycol diglycidyl ether,epoxy resin (E-51) and triphenylsulphonium hexafluoroantimonate (UVI-6976).The mechanical properties of the UV-cured films were determined,giving 46.25 MPa of tensile strength,1487.26 MPa of Young’s modulus and 6.27% of elongation at tear.
