摘要：通过差示扫描量热法(DSC),测定改性豆基改性蛋白胶的热反应特性,确定热压温度参数;并采用正交试验法,探讨用改性豆基蛋白胶压制杨木胶合板的热压工艺。结果表明:在压力1.4 MPa,温度165℃,时间1.4 min/mm,双面涂胶量220 g/m2的条件下,试板的胶合性能可达到GB/T 9846-2004中普通Ⅰ类胶合板的要求。
The thermal behavior of a modified soy-based protein adhesive was characterized with differential scanning calorimetry （DSC） in this study. After its theoretical curing temperature range from the DSC was identified, the soy-based adhesive was used to manufacture poplar plywood （250 mm×250 mm×4mm） in the laboratory. An orthogonal method was used to design an experiment to investigate effects of the process parameters on plywood bonding performance. Optimal process parameters were the press pressure of 1.4 MPa, press temperature of 165 ℃, pressing time of 1.4 min/mm, and adhesive spread of 220 g/m^2. The result showed that the bonding strength of the plywood, after accelerated aging test （4-hour boiling, 20-hour drying, and 4-hour boiling）, exceeded the requirement of the Chinese National standard, GB/T 9846-2004, for type Ⅰ general purpose plywood.
