- 摘要:
- 以表面活性剂AD改性大豆分离蛋白（SPI），然后与马来酸酐（MA）接枝后，再与环氧树脂（EPR）共混制备胶粘剂，采用L9(34)正交试验设计，探讨SPI、AD、MA及EPR用量对胶粘剂胶合性能的影响，并采用红外光谱及示差扫描量热仪探讨了SPI胶粘剂的胶粘机理。结果表明：最优工艺条件为每150 g溶剂水中，SPI用量15 g、AD用量为SPI的2.5wt%、MA1.5 g、EPR15 g；红外光谱和热性能分析表明SPI和EPR之间发生了化学反应。
- Abstract:
- In order to prepare a kind of bio-adhesive，the soy protein isolate was first treated with a kind of anion detergen AD，then gratfed with maleic anhydride(MA)，followed by blending with epoxy resin(EPR).The orthogonal experiment L9(34)was carried out to study the effects of the dosage of SPI，AD，MA and EPR on the bonding strength of the adhesive，respectively.Fourier transform infrared spectroscopy(FTIR)and differential scanning calorimetry(DSC)were employed to investigate the bonding mechanism of the adhesive.The optimum ingredients of the adhesive were cleared as 15 g SPI，2.5wt% AD，1.5 g MA and 15 g EPR in each 150 g water as solvent.Reaction between SPI and EPR was proved to have happened from the analysis by FTIR and DSC.
