以环氧树脂和丙烯酸为基本原料
设计并合成了紫外光固化用环氧丙烯酸齐聚物.考察了反应温度对酯化反应程度的影响
确立了温度-时间控制函数
利用SEM和IR光谱仪对光固化行为进行了结构和红外性能表征.并测定了光引发剂含量不同的树脂体系的线收缩率.结果表明:环氧丙烯酸酯化反应的适宜温度为(90~110)℃
UV固化后树脂体系的线收缩率约为2.4%
且固化程度好
交联度高.
Using epoxy resins and acrylic acid as raw materials
the authors have designed and synthesized epoxy acrylate(EA)by ultraviolet solidification.After investigating the effect of reaction temperature of esterification reaction
the authors have established the control function of temperaturetime;the structure and infrared nature of solidification behavior can be characterized by SEM and IR.In the research
linear shrinkage rate of the various systems of different photo-initiator content after UV-cure has been measured.The results show that preference temperature of esterification reaction is from 90 ℃ to 110 ℃
linear shrinkage rate of resins system after UV-cured is about 2.4%
and the resins system have good state of cure and high degree of cross linking.
