摘要
本文叙述了利用碱法制浆废液中的碱木素同苯酚、甲醛缩合制取结构材料粘合剂的方法。用正交设计法确定了最佳工艺条件,并在此条件下制取了粘合剂。以该粘合剂制造的胶合板的胶合强度、含水率等项性能指标均超过国家Ⅱ类胶的水平。
The methods for preparing structural material bonding agent by condensing the alkaline lignin in the wast liquor of soda pulping process with formaldehyde and phenol are described.The optimum condition was determined by orthogonal design,and a bonding agent was prepared under the condition.The bonding strength and moisture content of the ply- wood manufactured by the bonding agent overtook the National Standar GB738-75 and the demands of GB738-75 for the adhesives of the second class.
