Description

一种阻燃型无溶剂双组分聚氨酯结构胶及其制备方法
技术领域
本发明涉及一种阻燃型无溶剂双组分聚氨酯结构胶及其制备方法,属于聚氨酯胶黏剂技术领域。
背景技术
双组分聚氨酯结构胶是聚氨酯胶黏剂众多胶种中的一种,分为溶剂型和无溶剂型。无溶剂型双组分聚氨酯胶黏剂具有以下特点:1)100%的固含,原料全部利用,无溶剂挥发,属于节能减排技术;2)属于反应型胶黏剂,两组分混合后发生交联反应,初粘性好,粘接强度大,室温固化和加热固化皆可;3)两组分可调节性好,在制备时可以调节原料的组成和相对分子质量,使得室温下具有合适的粘度,固化时能达到理想的固化效果;4)使用时可以通过催化剂来调节固化速度;5)耐低温性能好,柔韧度高,耐冲击抗疲劳性优异,气密性好,可作密封胶和结构胶;6)原料来源丰富,应用范围广泛。无溶剂双组份聚氨酯胶黏剂在很多工业领域均有应用,然而随着经济发展和工业技术进步,人们对无溶剂双组份聚氨酯胶黏剂的性能要求也在不断提高,现有的无溶剂双组份聚氨酯胶黏剂已经无法满足一些特殊领域的需求。
CN 106221654 A公开了一种阻燃双组分聚氨酯胶黏剂,其中的A组分由二异氰酸酯、含阻燃基团的多元醇和反应型阻燃剂组成,B组分由扩链剂、交联剂、含阻燃基团的多元醇和反应型阻燃剂组成。CN 108084947 A公开了一种反应型阻燃双组分聚氨酯胶粘剂,以聚醚多元醇、甲苯二异氰酸酯为主要原料,引入了反应型阻燃剂二溴新戊二醇,通过半预聚物法进行制备。以上两种双组分聚氨酯胶黏剂虽然阻燃性能良好,但都存在以下不足:1)固化速度慢;2)力学强度偏低,粘接力弱;3)毒性较大,环保性低;4)双组分混合使用时,配比的实用性低。
因此,有必要开发一种综合性能更好、安全环保、适用性好的阻燃型无溶剂双组分聚氨酯胶黏剂。
