Description
技术领域
本发明涉及高分子技术领域,特别是涉及一种抗裂变低卤高透明环氧树脂封胶。
背景技术
环氧树脂封胶一般由环氧树脂、固化剂、促进剂、稀释剂、其它助剂等组成。其中,稀释剂普遍采用卤素含量为数万PPM的稀释剂,在添加量为10%左右的情况下,卤素含量远超欧洲标准,而采用低卤素稀释剂时,产品粘度、玻璃态转化温度、吸水率的性能又很难协同好。
并且,现有的环氧丙烯酸树脂的黏度大,黏度大会致使成品胶粘剂的粘度高,灌胶时生产效率低并且易产生气泡,较低的玻璃转化温度会导致固化后的交联网络结构在环境温度高于Tg时出现断裂分解,出现黄变、强度下降等性能损失,从而影响产品的使用寿命,因此限制了其应用环境。
发明内容
鉴于此,本发明的目的在于提供一种抗裂变低卤高透明环氧树脂封胶。
本发明的目的是通过以下技术方案来实现的:

(2)组分B的制备:将固化剂、促进剂和增韧剂按配比加入到反应釜中,50-60℃充分混合后得B组分。
