| 摘 要： | 为了降低豆基蛋白质胶粘剂的黏度、提高胶合板的耐沸水胶接强度和满足工业化的生产要求,对传统豆基蛋白质胶粘剂进行改性,并通过胶粘剂的黏度、pH值、凝胶时间、耐沸水胶接强度以及热分析结果等确定了改性剂的合理用量。然后以热压温度、热压时间、热压压力和涂胶量作为试验因素,以胶接强度作为考核指标,采用正交试验法优选出制备胶合板用改性豆基蛋白质胶粘剂的较佳工艺条件。结果表明:改性剂的合理用量(质量分数)是40%;胶合板的较佳热压工艺参数是热压温度140℃,热压时间5 min,热压压力1.2 MPa,双面涂胶量310 g/m2;在此较佳热压工艺条件下制备的胶合板,其耐沸水胶接强度较理想(为1.12 MPa),并且满足Ⅰ类胶合板的标准要求。
