摘 要:以氯乙酸钠为阴离子化试剂,对阳离子瓜尔胶进行改性,制备了具有不同羧基含量的两性瓜尔胶,通过浆内添加研究了两性瓜尔胶羧基含量和用量对卷烟纸增强性能的影响。结果表明:两性瓜尔胶应用于卷烟纸中的增强效果优于阳离子淀粉及非离子瓜尔胶,羧基含量为2%的两性瓜尔胶样品在用量为0.3%时,抗张指数、撕裂指数、耐破指数和裂断长分别提高8.52%、3.91%、13.66%和16.95%。The amphoteric guar gum(AGG) was synthesized by reacting cationic guar gum(CGG) with sodium chloroacetate.The effects of carboxyl group content and dosage of AGG on the strengthening properties of cigarette paper were studied,and the nonionic guar gum(NGG),cationic starch(CS) was used for comparison.The results showed that the synthetic products have better strengthening properties.While the dosage of AGG(about 2% carboxyl group content) was 0.3%(based on dry pulp),tension index,tear index,burst index and breaking length increased by 8.52%,3.91%,13.66% and 16.95%.
