目的-探索一种新的方法来制备具有适当性能的豆基胶粘剂，以满足木材工业的潜在应用。设计/方法/方法-使用三种化学物质对豆粉中的蛋白质进行改性。通过正交试验设计，制备了9种大豆基胶粘剂。通过测定胶合板的剪切强度，评价了9种配方胶合板的粘接强度。在统计分析的基础上，确定了主要影响因素和最佳配方。用傅里叶变换红外光谱进一步研究了其对蛋白质分子的修饰效果。为了便于实际应用，对最佳配方胶粘剂的粘度进行了测定，以确定其可能的使用寿命。通过添加3种添加剂来优化配方，以减少霉菌的生长。结果表明，根据豆粉质量，石灰乳、氢氧化钠和硅酸钠的最佳组合为10、2和20%。
Purpose – To investigate a new approach for making soy‐based adhesive having appropriate properties for potential application in wood industry.Design/methodology/approach – Three chemicals were used for modifying protein contained in soy flour. According to orthogonal experiment design, nine soy‐based adhesives were prepared. Shearing strength of plywood bonded with these adhesives was measured to evaluate the bonding strength of nine formulas. Based on statistic analysis, the main effect factor and an optimised formula were determined. Further investigation on the modification effect to protein molecule was conducted by Fourier Transform Infrared Spectroscopy. In order to facilitate practical application, the viscosity of optimum formula adhesive was measured to determine possible working life. Three additives were added to optimise formula for reducing mould growth.Findings – Based on soy‐flour mass, the best combination of lime milk, sodium hydroxide (NaOH) and sodium silicate was 10, 2, and 20 per cen...
