摘要： 以甘油、腰果酚缩水甘油醚（CGE）、酸酐及丙烯酸（AA）为主要原料，通过改变酸酐种类制得了一系列腰果酚基光固化树脂（AGC）；用傅里叶红外光谱（FT-IR）表征了树脂的结构；用凝胶渗透色谱（GPC）表征了树脂的相对分子质量；同时以 AGC 树脂为主体制备了 UV 固化涂料，考察了该涂料在 Q-panel 铝板上固化后的基本性能；并采用热重分析（TA）和差示扫描量热（DSC）考察了固化膜的热稳定性（T_d10）及玻璃化转变温度（T_g）。结果表明：该 UV 固化涂料能较好地兼顾高生物基含量与优异综合性能，具有广泛的开发和应用前景。

Abstract: A series of bio-based acrylic resins (AGC)were synthesized from renewable glycerol, cashew phenol ether (CGE) anhydride and acrylic acid(AA), which were used to prepare a series of UV curable coatings. The properties of cured film on Al sheet were also studied in this paper. The molecular structure of AGC was characterized by FT-IR. The molecular weight(M_n)and molecular weight distribution index (PDI) of AGC were characterized by GPC.The glass transition temperature (T_g) and the thermal decomposition temperature(T_d10)of cured film were investigated by DSC and TGA respectively. The results showed that the UV curable coatings gave a good balance between excellent performance and high content of bio-based substance, enabling a wide range of development and application.
