中文摘要:
      目的 研究电磁吸收剂的加入对UV光固化体系光聚合动力学的影响。方法 采用实时红外光谱技术研究光照强度、光引发剂含量、电磁吸收剂种类及其含量对光聚合动力学的影响。结果 光强增加既可以提高聚合体系反应速率,又可以提高最终双键转化率。随着引发剂含量的增加,最终双键转化率从76%提高到100%,但过高的引发剂含量会降低相对反应速率。以氧化石墨烯为电磁吸收剂的油墨最终双键转化率较高,以Fe3O4为电磁吸收剂的油墨相对反应速率较高,达到最大相对反应速率时间在10 s内。电磁吸收剂含量增大会降低油墨最终双键转化率,对油墨反应速率到达最大值的时间影响不显著。结论 光照强度、光引发剂含量、电磁吸收剂种类及其含量对UV电磁吸收油墨光聚合过程均有较大 影响。
英文摘要:
      The work aims to study the influence of the addition of electromagnetic absorber on photopolymerization kinetics of UV photocuring system. The effects of light intensity, photoinitiator content, type and content of electromagnetic absorbers on photopolymerization kinetics were researched by real-time infrared spectroscopy (RT-IR). The reaction rate of the polymerization system and the final double bond conversion rate were improved with the increase in the light intensity. With the increase in the initiator content, the final double bond conversion rate was improved from 76% to 100%; however, the relative reaction rate would be reduced with excessive initiator content. The final double bond conversion rate of the ink was higher with the oxidized graphene as the electromagnetic absorber. The relative response rate of the ink was higher with Fe3O4 as the electromagnetic absorber. The maximum relative reaction rate was reached within 10 s. When the content of electromagnetic absorber was increased, the final double bond conversion rate would be decreased, and the time for the ink reaction rate to reach the maximum value was subject to no significant influence. Light intensity, content of photoinitiator, type and content of electromagnetic absorber have great influence on the photopolymerization process of UV electromagnetic absorption ink.
