摘要
以葡萄糖代替甲醛,在碱性条件下合成了葡萄糖苯酚树脂胶粘剂。用红外光谱(IR)对其结构进行了分析,并通过正交实验获得了该树脂合成的最佳反应条件:pH=11,n(葡萄糖):n(苯酚)=8:1,反应温度120℃,催化剂用量14．3%,反血时间4 h;同时对树脂的固化条件进行了系统研究。
In alkali condition ,glucose-phenol resin adhesive by using D-glucose instead of formaldehyde was prepared successfully. The structure was characterized by IR,and through orthogonal experiment the optimum conditions of the reaction were obtained： pH value is 11 ,molar ratio of glucose to phenol is 8：1 ,the weight of catalyst is 14.3%（percent of the weight of D-glucose）,reaction temperature is 120 ℃ ,reaction time is 4 h,and the curing reaction of the resin was also studied by this method.
