Description
本发明属于新材料领域,具体涉及一种快渗速凝高分子材料及其制备方法与应用。
聚氨酯材料被广泛用于建筑领域、日用品领域、交通领域等。但在某些特定应用场合下,如潮湿环境和水下环境,异氰酸酯和多元醇的反应进程极易受到外界环境中水分的影响而导致聚氨酯发泡,力学性能大幅下降;且异氰酸酯和多元醇反应时通常需要添加催化剂活化单体来加快反应速率,反应受催化剂影响较大,不易实现可控;此外常用的有机锡类催化剂对环境和人体都是有害的,这些因素都一定地限制了聚氨酯材料的环境适应性和实用性。
聚脲材料是异氰酸酯和多元胺反应得到的一类聚合物材料。异氰酸酯和多元胺的反应活性较高,因此无需催化剂就能实现快速固化,对湿气、低温不敏感,不受环境温度、湿度的影响。但聚脲材料的反应速度较快,难以控制;更为重要的,聚脲材料的粘度较高,使得其使用时较为不便,一般需要专业人员操控成套设备,整体操作复杂且施工成本较高,难以满足特殊场合的使用需求。
综上,现有的聚氨酯/聚脲材料存在机械性能较弱、环境适应性较差、可操作性不足等方面的问题,急需发展一种快渗速凝高分子材料,以解决上述问题。
发明内容

本发明所述快渗速凝高分子材料基于反应活性较高的聚氨酯/聚脲反应,摒弃了传统方法中使用的有毒催化剂,引入了降粘缓凝剂、反应性溶剂和增塑剂等组分,在常规固化材料基础上实现了低粘度、快固化、高强度、环境适应性优异等目标。在常规条件下使用时,降粘缓凝剂、反应性溶剂和增塑剂降低了体系的粘度,便于材料快速润湿并充分渗入基材。在潮湿/水下条件下使用时,上述组分可以构建疏水环境、屏蔽水对交联反应的影响。反应过程中,异氰酸酯和多元醇/胺及反应性溶剂快速交联,形成三维网络构架,降粘缓凝剂和增塑剂借由与网络的强相互作用均匀填充在网络内部。反应完成后,高交联密度的网络保证了良好的力学性能,同时内部的降粘缓凝剂和增塑剂起到增韧效果并且防止溶胀,使得材料韧而强、稳定性好。
相对于现有技术具有如下优点和效果:
(1)常规的聚氨酯材料体系粘度较大、可操作性差、且需要加入对环境有害的有机锡类催化剂;常规的聚脲材料反应速度快、使用时需要配套设备、可操作时间短。而本发明所述的快渗速凝高分子材料通过加入低粘度的降粘缓凝剂、反应性稀释剂和增塑剂等,极大地降低了材料的粘度,操作极其方便且可以实现固化速度可控;同时材料体系中不含催化剂,反应完成后无挥发及残留,具有环境友好性。
(2)常规的聚氨酯材料在有水的环境下使用时容易与水反应而发泡。而本发明所述的快渗速凝高分子材料由于高反应活性,可在-20℃至50℃的宽温度区间使用;此外,基于独特的溶剂屏蔽作用,材料反应过程中体系基本不受水的影响,能够在潮湿、水下等恶劣环境下使用。
(3)本发明所述的快渗速凝高分子材料使用后在5分钟到2小时内即可完全固化,固化后力学性能优异:抗压强度≥10MPa,抗折强度≥5MPa,拉伸强度≥2MPa。
(4)本发明所述的快渗速凝高分子材料由于低粘度、快反应、固化时间可控、高强度、稳定性好、环境适应性优异的特性,可拓展多种应用场景:可作为涂料或者粘合剂用于各类基材(特别是多孔基材)的加固、修复、防护;可作为应急材料拓展应用于工程设施的便捷构筑、抢修抢建;还可应用于特种工程的基础加固。
