【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1,4-环己烷二甲醇(CHDM)和环氧氯丙烷(ECH)为原料合成了1,4-环己烷二甲醇二缩水甘油醚(CHDMGE)。研究了催化剂三氟化硼乙醚络合物用量、ECH和CHDM摩尔比,以及成环反应温度这些因素对其合成反应的影响,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CHDM和ECH总量的0.40%,ECH和CHDM较佳摩尔比为3.61.0,NaOH和CHDM较佳摩尔比为2.81.0,以及较佳的成环反应温度为30℃。同时,把三芳基锍鎓六氟锑酸盐作为引发剂,加入到CHDMGE中制备了阳离子型紫外光固化树脂,其紫外光固化膜的拉伸强度36.59 MPa,杨氏模量1264.52MPa,断裂伸长率7.16%。更多还原

【Abstract】 1,4-cyclohexanedimethanol glycidyl ether(CHDMGE)was synthesized with 1,4-cyclohexanedimethanol(CHDM) and epichlorohydrin(ECH) as raw materials,using boron trifluoride ether complex as the catalyst,and sodium hydroxide as the closing ring agent.The closing ring temperature,the dosage of the catalyst,and the moral ratio of ECH to CHDM were optimized.The optimal synthesizing conditions are 0.40% of the catalyst mass fraction,3.6/1.0 as the ratio of ECH/CHDM,2.8/1.0 as the ratio of NaOH/CHDM,and the closed ring reaction temperature 30 ℃.Meanwhile,the cationic type UV-curing coating was prepared with CHDMGE and triphenylsulphonium hexafluoroantimonate(UVI-6976).The mechanical properties of the UV-cured films were determined,giving 36.59MPa of tensile strength,1264.52MPa of Young’s modulus and 7.16 %of elongation at tear.更多还原
