【摘要】 选择自由基-阳离子混杂光固化体系,改变预聚物的种类,研究预聚物的种类对混杂固固化体系的影响,重点探讨了环氧树脂E44,单官能团氧杂环丁烷以及双官能团氧杂环丁烷对混杂光固化体系黏度、固化速度、柔韧性和体积收缩率的影响。研究表明,环氧树脂对混杂体系的性能影响较大,可以改善混杂光固化体系的柔韧性以及体积收缩率,并从理论分析其对混杂光固化产生影响的原因。更多还原

【Abstract】 This paper choose the radical- cationic hybrid UV curing systems and oxetane cationic UV curing system as rapid prototyping,study the performance of the system as the change of the kinds and the amount of pre-polymer,and the impact of the ratio of the pre-polymers to the system volume shrinkage.Studies show that the type and content of the pre-polymer have a great impact on the system volume shrinkage,and analysis the result from the perspective of the theory.The results shows that the epoxy resin can reduce the volume shrinkage hybrid UV curing system and can also improve the flexibility of the material cured film.更多还原
