摘要:
采用萜烯马来酸酐(TMA)、环氧氯丙烷(ECH)为原料合成萜烯基环氧树脂(TER),然后引入丙烯酸(AA)合成紫外光(UV)固化萜烯基环氧丙烯酸酯(TEA)。研究物料配比、催化剂种类、反应时间、温度及阻聚剂用量对反应以及产物性能的影响。用傅里叶红外光谱仪(FT-IR)对产物结构进行表征,并考察树脂在UV固化后的力学性能,测试不同光引发剂配比下涂膜的铅笔硬度、附着力、柔韧性,最后用热分析仪(TGA)对涂膜的热稳定性进行表征。筛选出的最佳工艺条件为:以苄基三乙基溴化铵(TEBAB)为催化剂,环氧氯丙烷(ECH)与萜烯基马来酸酐(TMA)的物料配比为n(ECH):n(TMA)=10:1,开环酯化的最佳反应温度为100 ℃,最佳反应时间为2 h,以反应体系总质量0.5%的对苯二酚作为反应的阻聚剂,以m(IR184):m(1173)=1:1的ID(1173/IR184)为光引发剂。在最优条件下所制备的萜烯基环氧丙烯酸酯经UV固化后,涂膜的铅笔硬度为3H+,附着力为1级,柔韧性为5 mm,且耐热性较好,可以达到UV固化涂料的使用要求。
Abstract:
UV-curable terpenyl epoxy acrylate(TEA)was prepared by combination arcylic acid(AA)and terpene based epoxy resin(TER)synthesized from terpene maleic anhydride(TMA)and epoxy chloropropane(ECH).The effects of the materials ratio,the kinds of catalysts,the reaction time and temperature,the concentration of inhibitor on the reaction and the properties of the product were discussed.Fourier transform infrared spectroscopy(FT-IR)was used to characterize the structure of the products.The mechanical properties of TEA were investigated under the different ratios of photoinitiator,such as the pencil hardness,adhesion,flexibility,and the thermogravimetric analyzer(TGA)was used to characterize the thermal stability of the film.The appropriate reaction conditions were as follows:triethyl benzyl ammonium bromide(TEBAB)as the catalyst,the material ratio of epichlorohydrin(ECH)and terpene maleic anhydride(TMA)of 10:1,the temperature of ring-opening esterification reaction of 100 ℃,reaction time of 2 h,0.5% of hydroquinone as polymerization inhibitor,and m(IR184):m(1173)=1:1 of ID(1173/IR184)as photoinitiator.The TEA prepared could meet the requirements for the use in UV curing coatings because of the better heat resisting property,3H+ pencil hardness,1 grade adhesion,and 5 mm flexibility.
