摘要
UV光油的成膜性质对包装印刷的质量影响很大,特别是UV光油固化膜层的柔韧性。现有的膜层柔韧性评价方法存在不统一,而且多限于定性评价,没有形成科学的评价体系。提出了一种新的膜层柔韧性的评价方法,即应力-应变曲线评价方法。采用该方法对UV光油固化膜层柔韧性的分析结果表明:单、双、三官能团单体中,双官能团单体制备的UV光油固化膜层柔韧性最佳;在2491、1400、2513、EB270、2258 5种预聚物中,使用2491制备的UV光油固化膜层的柔韧性最佳。
The performance of UV curable varnish film has a great effect on the quality of package printing products,especially the flexibility.The existing methods of estimating the flexibility of film are inconsistent and most of these are qualitative assessment,and there has not a scientific system.A new method of estimating flexibility of film was put forward,which we named stress-strain curve method,with which we studied the flexibility of UV curable varnish film.The results indicated that UV curable varnish prep...
