Description
技术领域
本发明涉及防水涂料技术领域，具体的，涉及一种高性能聚氨酯防水涂料。
背景技术
聚氨酯防水涂料是以聚氨酯树脂为主要成膜物质的一类高分子防水材料，是由异氧酸酯基(-NCO)的聚氨酯预聚体和含有多羟基（-OH)或氨基(-NH2)的固化剂以及其他助剂的混合物按一定比例混合形成的一种反应型涂膜防水材料。
聚氨酯防水涂料在建筑防水中应用广泛，可适用于各种屋面防水工程，如地下建筑防水工程，浴室、卫生间防水工程，地下管道防水等室内或地下防水和高速、铁路、无砟轨道、桥面等室外防水。
但是，聚氨酯防水材料固化后，聚氨酯材料偏脆，缺乏弹性，因此，为了提高涂层的柔性问题，一般采用添加增塑剂的方式来提高涂层的柔性，但添加的增塑剂在阳光下长久暴晒会出现迁移，增塑剂迁移后涂层的脆性会增加，导致聚氨酯防水涂料的性能下降，缩短聚氨酯防水涂料的使用寿命。
发明内容
本发明提出一种高性能聚氨酯防水涂料，解决了相关技术中的聚氨酯防水材料脆性大，耐紫外线性能差的问题。
本发明的技术方案如下：

作为进一步技术方案，所述二异氰酸酯包括异佛尔酮异氰酸酯、六亚甲基二异氰酸酯、苯二亚甲基二异氰酸酯中的一种。
作为进一步技术方案，所述填料包括沉淀硫酸钡、石英粉、云母粉中的一种或多种。
作为进一步技术方案，所述聚醚多元醇由低分子量聚醚多元醇和高分子量聚醚多元醇组成；所述低分子量聚醚多元醇分子量为400，所述高分子量聚醚多元醇分子量为1000-3000。

作为进一步技术方案，所述低分子量聚醚多元醇和高分子量聚醚多元醇的质量比为1:0.5-1.5。
作为进一步技术方案，所述低分子量聚醚多元醇和高分子量聚醚多元醇的质量比为1:1。
作为进一步技术方案，所述预聚体的制备方法为：将聚醚多元醇投入反应釜中，搅拌升温至100-105℃，脱水，然后降温至50-60℃后，加入异氰酸酯，反应后，得到预聚体。
