| 摘 要： | 采用《非木质造纸原料成分分析方法》(GB 2677.2—93)和红外光谱分析法,分析了向日葵秆主要成分、基团结构特征等,结果表明:向日葵秆超微粉具备作为酚醛树脂添加剂的条件。对向日葵秆超微粉与酚醛树脂混合体系的胶合性能、热力学反应性质、游离苯酚质量分数、价格成本等分析,结果表明:向日葵秆超微粉与酚醛树脂易混合;当超微粉的添加量达到m(酚醛树脂)∶m(向日葵秆超微粉)=100∶11时,胶液的黏度比较理想,游离苯酚的质量分数从加入面粉m(酚醛树脂)∶m(面粉)=100∶25时的0.30%降至0.16%,胶合板强度达到了国家标准(GB/T 9846—2004)规定的Ⅰ类胶合板的要求,向日葵秆超微粉可以替代部分工业面粉作为酚醛树脂添加剂使用,每生产1 m3的胶合板胶黏剂使用成本至少节约30元。
