| 摘 要： | 研究了树脂酸烯丙酯作为单体进行UV光固化反应的影响因素及其固化产物性能。采用红外光谱法对双键转化率进行了表征和分析,并对固化膜性能进行测试。结果表明,双键转化率随光照时间的增加而增加,随引发剂含量增加先上升后下降;固化过程中,表干时间随引发剂用量、光照强度的增加及光照距离的减小而变短,即相对固化速率增加;在较佳条件UV光照距离4.5 cm、光照强度100%下,以8%米氏酮(商品名MK)为引发剂、光照时间250 s时乙烯基双键转化率为97.9%,以5%2羟-基-2-甲基苯丙酮(商品名Darocure 1173)为引发剂、光照时间300 s时乙烯基双键转化率达97.6%;固化膜具有很好的柔韧性、耐冲击强度及附着力,具有较好的硬度及耐酸、耐碱、耐盐、耐水性。

| Abstract: | Properties of cured product and affecting factors of the reaction were researched using allyl resinate as monomer.Conversion rate of vinylic double bonds was characterized and detected by FT-IR analysis and mechanical properties of cured films were detected.Results showed that conversion of double bonds first increased and then decreased with the increase of the dosage of initiators,and increased with the increase of irradiation time.Surface drying time became shorter,that is,relative curing speed became fa... |
