乙烯基单体改性水性聚氨酯的合成及其用于烟包印刷用光油
Synthesis of vinyl monomers modified waterborne polyurethane and its application as gloss oil used in cigarette package printing
摘要
Abstract
A series of environment-friendly composite materials of vinyl monomers modified waterborne polyurethane(WPUA) with high stability and no triethylamine are prepared by using high temperature-resistant polyester polyol and 4,4′-methylenebis(cyclohexyl isocyanate) as main raw materials,which are copolymerized with different vinyl monomers respectively. The structures and properties of WPUA emulsions and films were characterized by FTIR,TEM,TG,DSC and XRD. And the performance of waterborne colored paint made from WPUA emulsion on aluminum foil paper was investigated. The results show that the WPUA emulsion modified with vinyl monomer has good stability,and the emulsion can coexist with ethanol without demulsification. The particle sizes of the modified WPUA emulsion increase and the particle size distribution is uniform. The heat resistance of the modified WPUA films is enhanced,the glass transition temperature is increased,and the crystallinity is weakened. The flexibility,gloss,adhesion of WPUA on aluminum foil paper are not affected,while the heat resistance is improved by modification with vinyl monomers. WPUA meets the requirements of the printing industry. Organic solvents are not required during the preparation and application process of WPUA. It meets the national standards for cigarettes packaging products and it is suitable for the promotion and application as gloss oil for packaging and printing.关键词
