摘要
以接枝率为考察目标用正交试验探索了反应温度、碱用量、反应时间、氯化苄及助剂季铵盐的用量5个因素对天然竹纤维苯甲基化改性的影响,确定了最佳反应条件。在NaOH溶液用量16 mL,反应温度120℃,季铵盐用量0.4 g,反应时间3 h,氯化苄用量15 mL的条件下,竹纤维的接枝率达143.68%。并通过FT-IR、SEM等分析方法对接枝的竹纤维微观结构进行了研究和表征。
Effects of reaction temperature, reaction time, the amount of alkali, henzyl chloride and quaternary ammonium on grating rate of benzylated natural bamboo fiber have been discussed. The optimum conditions were obtained： the amounts of NaOH solution, quaternary ammonium and benzyl chloride are respectively 16 mL,0.4 g and 15 mL; the reaction temperature and time are 120 ℃ and 3 h. Under the optimum conditions the highest grating rate was up to 143.68 %. The morphologies and structure properties of the resultant samples were also characterized by FT-IR analysis and SEM.
