Abstract
本申请涉及胶粘剂技术领域，具体公开了一种玻璃钢管道抢修用胶粘剂及制备工艺。一种玻璃钢管道抢修用胶粘剂，其原料包括：改性双酚A型环氧树脂、固化剂、玻璃纤维增强填料、硅烷偶联剂、苯基缩水甘油醚、端羟基丁腈橡胶和抗氧剂1076；改性双酚A型环氧树脂由双酚A型环氧树脂经端氨基聚醚接枝改性制备而成；玻璃纤维增强填料由羟基化玻璃纤维与石墨烯‑碳纳米管复合物经共价接枝制备而成。该胶粘剂可用于玻璃钢管道的应急抢修，具有低温固化速度快、粘接强度高、耐久性好的优点，能有效避免修补处开裂渗漏，适配低温、高压复杂抢修工况。其制备工艺操作简便、可控性强，可稳定制备出性能均一的胶粘剂，保障抢修效率和修补质量。
