摘要:
利用疏水性单体甲基丙烯酸缩水甘油酯（GMA）接枝改性大豆蛋白以期获得耐水性较好的大豆蛋白胶粘剂。大豆蛋白（SP）经过3 mol.L-1尿素溶液预处理变性后，以GMA为接枝单体，过硫酸铵-亚硫酸氢钠（APS-NaHSO3）氧化还原体系为引发体系，通过自由基聚合合成接枝改性大豆蛋白胶粘剂。用红外表征纯接枝物，结果表明接枝成功；研究了预处理时间、反应时间、引发剂加入量、单体加入量、反应温度对接枝改性大豆蛋白胶粘剂的粘接强度和耐水性的影响。结果说明接枝反应的确能够提高耐水性，并确定了最佳的反应条件。得出较佳的反应条件为：wsp4 g，wGMA3.39 g，wNaHSO30.2 g，wAPS：0.44 g，反应时间3 h，反应温度 70℃。
Abstract:
The hydrophobic monomer GMA was grafted onto soy protein(SP)in order to obtain the much better water-resistant SP adhesives.The graft copolymer of SP-g-PGMA was prepared by free radical polymerization with APS-NaHSO3?redox system as initiator after SP was pretreated by 3 mol.L-1urea solution which was as a denaturing agent.Pure grafted polymer was analyzed by IR indicating the success of grafting.Effect of different reaction conditions on grafted SP adhesives’ shear strength and water resistance，such as pretreatment time，reaction time，addition of initiator，addition of monomer，reaction temperature were studied.The experiment illustrated that grafting reaction can improve the water resistance of SP adhesives，and the optimal reaction conditions was determined，and these reactions were：4 g wsp，3.39 g wGMA，0.2 g wNaHSO3，0.44g wAPS，3 h of reaction time and 70℃reaction temperature.
