摘要

为了确定应用交联改性大豆蛋白胶制造胶合板的工艺,采用正交试验,分析热压工艺参数和涂胶量对胶合板剪切强度的影响。在试验优化的工艺参数:热压温度160℃,压力1.5MPa,时间2min/mm,双面涂胶量380g/m2等条件下,胶合板的湿状剪切强度满足GB/T 9846-2004《胶合板》中I类胶合板的要求,且不会随蒸煮时间的延长而出现明显下降,耐水性能稳定。

Abstract

In order to improve the wet shear strength of soy protein based adhesive,the authors used two resins as a cross-linking agent to modify soy protein based adhesive.The modified soy protein-based adhesive was then used to make plywood samples.The results showed that when processed at 160 ℃,1.5 MPa,2 min/mm,and 380 g/m2 glue spread,the plywood wet shear strength met the National Standard GB/T 9846-2004 requirement for I-level plywood.The cross-linking agent also dramatically improved the bonding performance of the plywood samples in boiling water.
