摘要:
研究了交联改性前大豆蛋白基胶黏剂的NaHSO3改性处理工艺对大豆蛋白基胶黏剂性能的影响。结果表明:当反应温度为30℃、反应时间为0.5 h、加入4% NaHSO3处理大豆蛋白,再经交联剂改性制备的大豆蛋白基胶黏剂胶合板干、湿强度满足GB/T 9846.3-2004中有关I类胶合板的强度要求。动态热机械性能(DMA)分析结果表明,NaHSO3改性处理后大豆蛋白基胶黏剂的机械性能和热稳定性都有所提高,固化起始温度略降低。差示扫描量热(DSC)和傅里叶红外光谱(FTIR)分析表明,经NaHSO3处理后蛋白质分子中的二硫键有明显的断裂,且有明显的DSC固化放热峰。交联改性前,大豆蛋白通过NaHSO3改性处理,可以降低大豆蛋白基胶黏剂的交联剂使用量,从而在不影响使用性能的前提下,进一步降低大豆蛋白胶黏剂的制作成本。
Abstract:
Before cross-linker modifying soy-based adhesive, early treatment process of soy protein was conducted and studied. The results showed that when treating soy protein with NaHSO3, the optimum condition would be:addition amount of NaHSO3 4% on solid content of soy protein, treating for 0.5 h at the temperature 30℃. Then adding cross-linker, the dry and wet strength of plywood with soy-based adhesive could satisfy with the requirement of GB/T 9846.3-2004 for I type plywood. The dynamic mechanical thermal analysis (DMA) indicated that soy protein treated by NaHSO3 had no obvious effects on the curing and thermal stability of soy-based adhesive, and the onset curing temperature of soy-based adhesive was lower than that of the un-treated by NaHSO3. Differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR) showed that disulfide bond of soy protein were broken and had obvious exothermic peak of DSC when treated by NaHSO3. The main conclusions were as follows:before cross-linker modifying soy-based adhesive, soy protein treated by NaHSO3 could reduce the addition amount of cross-linker agent, to further reduce the production cost of soy protein-based adhesive.
