中文摘要:

      生物胶乳以价格低廉、低碳环保、能够替代石化胶乳制备性能优良的涂料等优势被应用于造纸工业中。将生物胶乳不同比例替代聚乙烯醇并应用于彩喷纸底涂和面涂涂料中,分析了其对彩喷纸物理性能(如白度、不透明度、表面粗糙度、光泽度等)及印刷性能(如油墨吸收性等)的影响。结果表明,生物胶乳的加入可提高彩喷纸的白度、不透明度、光泽度、表面粗糙度、油墨吸收性等,降低紧度、耐破度、表面强度等性能。生物胶乳在底涂和面涂涂料中的替代率分别为60%和40%时,彩喷纸性能最佳。

Abstract:

      Biobased latex (biolatex) has been used as adhesive in papermaking industry, due to its advantages of low cost and environmental friendly. The biolatex can be the substitute for petrochemical-based latex used in paper and paperboard coatings preparation. The objective of this study was to analyze the physical properties of color ink-jet printing paper in which the biolatex replaced polyvinyl alcohol (PVA) in the coatings used for precoating and topcoating. In this paper, effects of biolatex on the physical properties of color ink-jet printing paper, such as brightness, opacity, PPS roughness, gloss, and ink absorption, IGT surface strength were studied. The results showed that the increase of biolatex substitution ratio resulted in higher paper brightness, opacity, gloss, PPS roughness, and ink absorption; but the paper density, bursting strength and surface strength decreased. It was also found that, the best substitution ratio of biolatex was 60% and 40% in the coatings for precoating and topcoating respectively.
