A tannin-based epoxy acrylate resin was prepared from glycidyl ether tannin (GET) and acrylic acid. The influence of the reaction condition for producing tannin epoxy acrylate was studied by FT-MIR, C-NMR, MALDI-TOF spectroscopy and shear strength. The best reaction conditions for producing tannin epoxy acrylate resin without bisphenol A was by reaction between GET and acrylic acid in the presence of a catalyst and hydroquinone at 95 °C for 12 h. FT-MIR, C-NMR and MALDI-TOF analysis have confirmed that the resin has been prepared under these conditions. The joints bonded with this resin were tested for block shear strength. The results obtained indicated that the best strength performance was obtained by the bioepoxy-acrylate adhesive resin prepared at 95 °C for a 12-h reaction.

一种基于单宁的环氧丙烯酸酯树脂由缩水甘油醚单宁（GET）和丙烯酸制备而成。通过傅里叶变换红外光谱（FT-MIR）、碳核磁共振（C-NMR）、基质辅助激光解吸电离飞行时间质谱（MALDI-TOF）光谱以及剪切强度研究了制备单宁环氧丙烯酸酯的反应条件的影响。在无双酚A的情况下制备单宁环氧丙烯酸酯树脂的最佳反应条件是在催化剂和对苯二酚存在下，GET与丙烯酸于95℃反应12小时。FT-MIR、C-NMR和MALDI-TOF分析证实了在此条件下已制备出该树脂。对用这种树脂粘结的接头进行了块体剪切强度测试。所得结果表明，在95℃反应12小时制备的生物环氧丙烯酸酯胶粘剂树脂具有最佳的强度性能。
