摘要/Abstract

摘要： 以浆液黏度、黏度热稳定性、黏附性及浆膜性能为评价指标，研究了几种氨基化合物对淀粉浆料的增塑作用。所研究的氨基化合物包括苯胺、乙醇胺、尿素等，通过对比试验来筛选出性价比较高的淀粉浆料增塑剂，探索合理的用量。结果表明：使用增塑剂能改善淀粉浆膜脆硬的属性，提高它的断裂伸长率和耐屈曲次数，降低磨耗，但会使淀粉浆膜的断裂强度有所下降。在上述几种增塑剂中，乙醇胺的作用效果最好，其用量推荐为淀粉干重的6%～9%。

Abstract: Effect of some amino substances used as plasticizers on the plasticization of starch sizing agents was investigated in terms of paste viscosity, viscosity stability, adhesion-to-fibers, and starch film behaviors. The plasticizers evaluated included aniline, ethanolamine, urea, etc. Superior plasticizer was found through control test, and the content was also determined. The experimental results demonstrated that the plasticizers could improve the fragility of starch film because breaking elongation and flex resistance of the film increased and wear loss decreased. However, tensile strength of the film decreased with the increase of plasticizer content. It was recommended that ethanolamine should be used for plasticizing starch with a content of 6%～9% based on dry weight of starch.

Key words: Starch, Warp sizing agent, Plasticizer, Starch film
