摘要:

由腰果酚与甲基丙烯酸缩水甘油酯(GMA)反应合成了烯丙基酯-Ⅰ型腰果酚(GMA-C)光固化单体,再进一步与甲基丙烯酸酐(MAA)反应合成了烯丙基酯-Ⅱ型腰果酚(MAA-GMA-C)光固化单体,并采用FT-IR、1H NMR和13C NMR表征了产物化学结构;研究了烯丙基酯型腰果酚光固化单体的紫外光固化特性、固化后漆膜的机械性能和耐化学介质性能。研究结果表明:烯丙基酯型腰果酚经紫外光辐照40 s可固化成膜,紫外光固化后的漆膜铅笔硬度最高可达4H、附着力2级,并具有较好的耐水、耐乙醇、耐盐水和耐酸性能。

Abstract:

The type-I cardanol with allyl ester group(GMA-C) was synthesized by the reaction of cardanol and glycidyl methacrylate(GMA), and further reacted with methacrylic anhydride(MAA) to prepare the type-II cardanol with allyl ester group (MAA-GMA-C). The chemical structure of the products were characterized by FT-IR, 1H NMR and 13C NMR. The UV curing properties of the prouducts, mechanical properties and chemical resistance of the cured film were investigated. The results showed that the cardanols with allyl ester group could be cured under UV irradiation for 40 s, the pencil hardness of the film could reach 4H, the adhesion force could reach grade two, and the cured film had better properties of water resistance, ethanol tolerance and acid resistance.

Key words: cardanol, glycidyl methacrylate, UV curing, synthesis, property
