应用于彩喷纸涂料中聚乙烯醇的消泡剂性能研究

A research on defoaming property of PVA in coating colors for color ink-jet printing paper

主要研究作为涂布彩喷纸用胶粘剂的聚乙烯醇在溶解、涂料配制、涂布过程中气泡的产生与消除,从而改善纸张的打印性能。涂布涂料主要由颜料、胶粘剂和助剂组成。聚乙烯醇(PVA)是最常用的胶粘剂,它是一种水溶性聚合物,由于具有良好的粘结性、成膜强度和颜料分散性,在造纸工业中常用作胶粘剂广泛运用于涂料的配制中。

Formation attd removal of foam in dissolution, coating colorss preparation and coating process of PVA, which is a kind of co-binders in the production of colored inkjet printing paper, were studied to benefit to improve paper＇s printing performance. Coating is mainly consisted of pigment, co-binders and additives. PVA, a kind of ordinary-used co-binders, is a water soluble polymer, which is often used in the coating preparation as co-binder in paper industry, because of good cohesiveness, high fihn strength and good dispersion to pigment.
