摘要
以含环氧基的光敏性丙烯酸酚醛环氧树脂为原料合成了一种可以在1％的碳酸钠溶液中溶解的光敏性酚醛环氧树脂(AAFEE)，研究了该树脂的合成条件及工艺。发现当反应温度为95℃、选用溴化季铵盐作为反应的催化剂、反应时间为3 h可获得在低浓度碱溶液中溶解的涂料用树脂(AAFEE)。当树脂中n(环氧基)：n(羟基)：n(琥珀酸酐)=3：7:6、3:7:5时，以此树脂制备的涂料具有优良的力学性能。光敏实验证明，AAFEE树脂中的碳碳双键具有较高的光学反应活性，光照15 s后转化率可达60％以上。
Abstract
A special photocurable acrylic cresol phenolic resin containing free epoxy group(AAFEE) which can be dissolved in 1% Na2CO3 was synthesized, it preparation conditions were studied in detail. Experimental data showed that it can be successfully prepared when reaction temperature is 95℃, catalyst is tetrabutylammonium bromide, and the reaction time is 3 h. The coating made from AAFEE had excellent properties if n(epoxy group) : n(hydroxyl) : n(amber anhydride)=3: 7 : 6,3: 7: 5. More than 60％ of the carbon-carbon double bonds in AAFEE was reacted under UV-light for 15 s.
