摘要
本文以端羧基聚醚(CTPE)对双酚A型环氧丙烯酸酯树脂实施改性,制得了一种光敏预聚物——端羧基聚醚改性环氧丙烯酸酶树脂(AEPE),对该预聚物的紫外光固化性能进行了研究。结果表明,CTPE含量对其柔韧性有很大影响,AEPE的断裂伸长率,断裂能随CTPE含量增加而明显增大,并在CTPE含量40phr左右时皆达到最大值。AEPE已在新开发的光敏滴塑水晶料和镭射玻璃粘合剂中获得应用。
Bisphenol A epoxy acrylate resin was modified with carboxy-terminated polyether and the UV curing properties of the modified resin were investigated. The content of the carboxy-terminated polyether in the resin showed great effect on the tougheness of the cured resin, and the cured resin, containing 40 phr carboxy-terminated polyether, showed the maximum elongation at break and maximum breaking energy.
