摘要
采用共缩聚方法合成了聚酯二元醇,并利用化学分析方法测定了其羟值和酸值。通过二次扩链方法制备了酯溶性聚氨酯,在此基础上配制了红色聚氨酯油墨,同时研究了油墨对BOPP的附着力与聚氨酯添加质量的关系。利用红外光谱法对聚酯二元醇及聚氨酯进行了定性表征,并研究了异氰酸酯的反应程度随反应时间的变化规律。
The polyester glycol was synthesized by copolycondensation, and the hydroxyl and acid value were determined by the chemical analysis method. Through the secondary chain extender, the ester-soluble polyurethane was obtained, with them the red ink was prepared, the relationship between adhesion of ink on the BOPP and polyurethane addition was studied. The infrared spectrometry was carried on the qualitative attribute to the polyester glycol and the polyurethane, and the responsiveness of isocyanate with the variation of reaction time has been studied.
