摘要
以果糖代替甲醛,在碱性条件下合成了果糖苯酚树脂胶黏剂。用响应面优化法对果糖苯酚树脂的合成条件进行了优化。以树脂黏度为考察指标,根据Box-Behnken的中心组合设计原理对实验进行设计和结果分析。用响应面优化法研究了温度、时间和催化剂用量对反应的联合影响,得出最佳工艺条件为:反应温度72.36℃,反应时间6.96h,催化剂用量7.98%。在此条件下,树脂的黏度为27.67s。同时用红外光谱(IR)对树脂结构进行了分析。
Under the condition of alkali, fructose-phenol resin adhesive was prepared successfully by using fructose instead of formaldehyde. Response surface methodology （RSM） was utilized for optimizing the reaction conditions. With using the viscosity as research index, the experimental design and results analysis were carried out according to the Box-Benhnken center combination design principle. The combined effect of temperature, time and the catalyst amount was investigated and optimized by using response surf＇ace methodology （RSM）. The optimum process conditions were obtained as follows： reaction temperature was 72.36℃, reaction time was 6.96h and the catalyst amount was 7.98%. The viscosity of resin was 27.67s, and the structure of the resin was characterized by IR.
