摘要：通过对大豆粉采用碱处理使大豆蛋白质大分子结构展开,暴露出的官能团进一步与甲醛反应生成稳定的蛋白质,这种物质与苯酚共聚反应生成改性豆基蛋白胶黏剂。采用单因素实验方法,探讨了改性豆基蛋白胶黏剂压制杨木三层胶合板的胶合工艺。分析了热压温度、热压时间和涂胶量对胶合板胶合性能的影响。结果表明:采用改性后的豆基蛋白胶黏剂,在压力为1.4NPa,温度为165℃左右,热压时间为1.4～1.6min·mm^(-1),涂胶量为220g·m^(-2),压制的杨木胶合板胶合性能较佳且达到Ⅰ类胶合板的标准。
The soybean flour is treated with hot caustic to denature the protein. Once the denaturation has opened the protein structure, the exposed functional groups can react with formaldehyde to produce a stable protein. Then this substance can react with phenol to produce a modified soy based protein adhesive. The solution to the optimum bonding technology of modified soy - based protein adhesive in poplar plywood manufacture is obtained by the single factor experimental method, in which three factors, such as hot-pressing temperature, time, and glue spread are analyzed. The results show that when the hot -pressing pressure is 1.4MPa, the temperature is about 165℃ , the time is between 1.4 and 1.6min · mm^-1 and the glue spread is 220g·m^-2, the bond properties of the poplar plywood are preferable and can meet the Chinese national standard of type Ⅰ plywood.
