摘　　要：为了减少制造胶合板过程中豆胶胶黏剂的用量以及降低豆胶胶黏剂的黏度,通过采用机械混合和超声波处理2种方法与空白试样进行比较,同时通过单因素试验进一步优化工艺参数的方法对蒸馏水稀释大豆胶黏剂进行研究,结果表明:经超声波处理40min的豆胶胶合性能较好,当m(豆胶):m_水=1:0.6时,胶合板的胶合强度可达到0.77MPa,可达到国家标准Ⅱ类胶合板的性能要求。In order to reduce viscosity and dosage of bean adhesive in plywood processing,the method of distilled water dilution bean adhesive was studied by comparing the bond strength of multi-plywood with bean adhesive mechanical mixing bean adhesive,ultrasonic treatment bean adhesive and blank sample,and the further optimization of the process parameters with single factor experiment.The result shows that the bond strength of multi-plywood with treated bean adhesive by ultrasonic for 40 min is the best,and when the mbean gum：mwater=1：0.6,the bonding strength of bean plywood can reach 0.77 MPa,which can reach the requirement of national standard for type Ⅱ plywood.
