摘要
纸张涂料具有粘弹性,主要是由于其中作为流变助剂的水溶性聚合物与其他组分的相互作用引起的。不同的流变助剂对涂料的影响程度不同。本文比较了CMC(羧甲基纤维素)、PVA(聚乙烯酸)和CMS(羧甲基淀粉)对涂料粘弹性能的影响,表明CMC比PVA和CMS更能提高体系的粘弹性能,并从组分间的相互作用方面分析了它们对粘弹性能的作用机理。
Paper coating has a pronounced viscoelastic character, and the degree of viscoelasticity is strongly connected with dissolved poly-
mer in the aqueous phase. The different thickeners have different effects on paper coating viscoelasticity character CMC, PVA and CMS
are compared in this article, and CMC has the strongest effect among the others.
