Description

一种快速结晶水性聚氨酯胶粘剂的制备方法
技术领域
本发明涉及一种快速结晶水性聚氨酯胶粘剂的制备方法。
背景技术
随着科技的发展,水性聚氨酯胶粘剂取得了长足的进步,在多个的领域替代了溶剂型聚氨酯胶粘剂。水性聚氨酯胶粘剂溶剂含量极低,绿色环保,使用便捷,粘接强度高,越来越多的人开始关注了使用水性聚氨酯胶粘剂。
目前,水性聚氨酯胶粘剂与溶剂型聚氨酯胶粘剂相比,最大的缺点在于,水性聚氨酯胶粘剂结晶速度慢,直接体现为初期粘接强度较低。这一特性使得水性聚氨酯胶粘剂替代溶剂型聚氨酯胶粘剂的用户意愿较低。
CN108084945A提出一种含纳米有机蒙脱土的聚氨酯乳液胶黏剂,采用纳米有机蒙脱土做封端剂,起到补强和诱导聚氨酯分子链结晶的效果,提高胶黏剂的初粘力,并且利用苯乙酮肟封闭异氰酸酯为潜在可反应基团,可与粘接界面的活性基团进一步反应,提高胶黏剂的粘接强度。
CN108300402A提出一种含纳米二氧化硅的聚氨酯乳液胶黏剂,采用纳米有机蒙脱土做封端剂,起到补强和诱导聚氨酯分子链结晶的效果,提高胶黏剂的初粘力,并且利用苯乙酮肟封闭异氰酸酯为潜在可反应基团,可与粘接界面的活性基团进一步反应,提高胶黏剂的粘接强度。
上述技术方案均以纳米级无机物作为聚氨酯乳液的封端剂,配合特定分子量的聚酯多元醇等,使纳米级无机物均匀稳定地分散于聚氨酯乳液中,诱导聚氨酯结晶,从而提高胶黏剂的初期粘接强度。
但无机物和有机物的相容性较差,虽然上述技术方案使用特定原料与无机物相匹配,但原料的批次差异甚至储存条件变化等均可能造成絮凝、沉淀等现象,在实际生产中可能造成严重后果。

所述羧基亲水剂为二羟甲基丙酸和二羟甲基丁酸中的一种。
所述扩链剂为乙二胺、丁二胺、已二胺中的一种或几种的组合物。
所述的润湿剂为普为化学CoaddTM W-1866、CoaddTM W-1855、CoaddTM W138和CoaddTM W110中的一种或几种的组合物;
