为了降低豆粕胶粘剂的粘度，提高其湿剪切强度，制备了豆粕胶粘剂、酶处理豆粕胶粘剂（ESM）和ESM接枝GMA（ESM-g-GMA）胶粘剂。通过流变性能测试、力学性能测试、傅里叶变换红外光谱（FTIR）和热重分析（TGA）对胶粘剂的性能进行了表征。结果表明，由于酶处理和GMA的存在，胶粘剂的表观粘度降低。用ESM-g-GMA胶粘剂胶合的胶合板湿剪切强度由0.45 MPa提高到1.05 MPa，达到了国家标准中胶合板的要求（≥0.7 MPa）。本研究还研究了ESM-g-GMA粘合剂的适用期和热压的影响。湿剪切强度在24 h内变化不明显。最佳热压温度为150 °C，热压时间为6 min。FTIR表明GMA成功接枝到ESM胶粘剂上。热重分析表明，ESM-g-GMA胶粘剂的峰值降解温度高于SM胶粘剂，这是由于交联反应在ESM胶粘剂和GMA单体之间形成了高分子致密结构。
In order to decrease the viscosity and improve the wet shear strength of soybean meal (SM) adhesive, in this study, SM adhesive, enzyme-treated SM adhesive(ESM), and the ESM grafted GMA (ESM-g-GMA) adhesive were prepared. The properties of these adhesives were characterized by rheological measurement, mechanical performance testing, Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). The results indicated that the apparent viscosity of the adhesives decreased due to the enzymatic treatment and the presence of GMA. The wet shear strength of the plywood panels bonded with ESM-g-GMA adhesive was significantly improved from 0.45 MPa to 1.05 MPa, which met the interior plywood requirement (≥0.7 MPa) of the China National Standard. This study also investigated the pot life of the ESM-g-GMA adhesive and the impact of hot pressing. The change in wet shear strength was not obvious within 24 h. The optimum hot press temperature and time were 150 °C and 6 min, respectively. FTIR showed that GMA was successfully grafted onto the ESM adhesive. TGA indicated that the peak degradation temperature of the ESM-g-GMA adhesive was higher than that of the SM adhesive due to the cross-linking reaction that created the macromolecular dense structure between the ESM adhesive and the GMA monomer.
