摘要

研究了在没有其它活化剂存在条件下，采用2-烷基蒽醌直接引发环氧丙烯酸酯体系的光交联反应。应用光谱方法和重量法测定了反应体系在光固化过程中双键含量、光交联密度、凝胶转化率和固化膜硬度的变化情况。实验结果表明，2-烷基蒽醌直接引发环氧丙烯酸酯类的光固化反应，具有很好的引发效率，可以和安息香双甲醚与硫杂蒽酮等光引发剂相比拟，并具有价格便宜、光固化可在空气条件下操作等优点，另外对反应体系的引发剂浓度、组分配比的影响以及对不同类型环氧丙烯酸酯反应体系的引发效果均进行了讨论。

Abstract

The photochemical erossilinking of epoxy acrylates directly initiated by 2-alkyl anthraquinones (AQ) in the absence of activators was studied in this paper. The changes of double bond content

photocrosslinking density

gel conversion and hardness of cured film in the ptotocuring process were monitored by photospectrometry and gravimetry. The experimental results show that the 2-alkyl AQ exhibits a high initiation efficiency which is comparable with dimethoxy-2-phenyl acetophenone and thioxanthone photoinitiators. Moreover AQ is very cheap and its photocuring can be operated in the air condition. The effects of initiator concentration

proportion of components and initiation efficiencies for different kinds of epoxy acrylates were also discussed
