Description

一种环氧树脂改性的聚氨酯防水涂料及其制备方法
技术领域
本发明属于涂料技术领域，具体涉及一种环氧改性的聚氨酯防水涂料及其制备方法。
背景技术
涂料是一种含颜料或不含颜料的，用树脂及油等制成的化工产品。将涂料涂覆在物体表面上能够干结成膜，使被涂物体的表面与环境介质相隔离，从而对被涂物体起到的保护和装饰的作用。
聚氨酯防水涂料属于化学反应型防水涂料，固化后是一种橡胶状的高弹性涂膜，该材料以其优良的综合性能，在世界范围内广泛应用。聚氨酯防水涂料根据其组成和固化机理，分为单组分和多组分两大类。多组分聚氨酯防水涂料现场施工时需按一定比例配料，机械搅拌，其搅拌过程中引入的起泡以及配料不准，搅拌不均匀等问题均会影响产品质量，因此而造成防水质量事故时有发生；而单组分涂料也存在一些难以避免的问题，尤其是由于液体聚氨酯流平性好，立面施工流淌特别严重，在立面施工无法上厚度等问题，已成为行业的难题。
针对以上问题，本领域多年来进行了深入探索，已有的解决方案致力于通过额外加入触变剂来改善产品的触变性能，使之粘而不稠，即可以好施工，又能在立面施工不流淌。但聚氨酯是极性材料，触变剂如气相白炭黑、氢化蓖麻油及其衍生物、有机膨润土等在聚氨酯体系中的触变效果不理想，存在粘度变大，不好施工等缺陷。
发明内容
为解决现有技术的不足，本发明提供一种环氧树脂改性的聚氨酯防水涂料，所述涂料包括如下重量份数的组成：环氧改性聚醚多元醇 30-50份、多异氰酸酯单体 10-20份、增塑剂 10-20份、固体填料 30-50份、潜固化剂 1-5份、催化剂 0.3-3份、消泡剂 0.1-2份、抗流挂剂 1-5份；

所述多异氰酸酯单体包括异佛尔酮二异氰酸酯、六亚甲基二异氰酸酯、苯二亚甲基二异氰酸酯、二环己基甲烷二异氰酸酯中的至少一种；

所述固体填料包括滑石粉、纳米二氧化硅、纳米氧化铝、纳米碳化硅、红金石型钛白粉中的一种或多种；使用时需对填料进行表明改性，具体步骤如下：（1）将固体填料在2%的稀硝酸中浸泡24h，以除去表面的杂质并使表面形成足够多的空隙以便与承接改性剂；然后200℃下干燥2h，彻底除去表面水分；（2）将处理后的填料与硅烷偶联剂按质量比称量后加入捏合机中充分捏合1-2h，然后转入烘箱中，加热处理2-3h，使硅烷偶联剂组分浸渍到表面空隙中，获得改性填料；改性后的填料可以与改性聚醚较好的键合，提高了粘度和抗沉降性能；
所述潜固化剂包括2-异丙基恶唑烷、2 ,2-二氢恶唑烷、2-异丙基-N-羟乙基-恶唑烷或2 ,2-二氢-N-羟乙基恶唑烷中的至少一种。
所述催化剂为有机锡催化剂，包括二丁基锡二月桂酸酯、辛酸亚锡、二醋酸二丁基锡中的至少一种；
所述消泡剂为有机硅消泡剂，优先聚醚改性有机硅消泡剂；
所述抗流挂剂为改性气相二氧化硅，所述改性气相二氧化硅是利用二氧化硅易于形成氢键的特性，与二元醇反应使其表面形成二元醇接枝的结构，进而提高其与涂料体系的相互作用，起到抗流挂的目的。所述二元醇优选聚醚二元醇；具体改性方法是将气相二氧化硅加入二元醇中，70-80℃下反应2-3h，降温得到二元醇接枝的气相二氧化硅结构。
本发明还提供所述一种环氧树脂改性聚氨酯防水涂料的制备方法，具体包括如下步骤：

（3）向步骤（2）所得反应体系中依次加入消泡剂、潜固化剂、催化剂、抗流挂剂搅拌分散30-40min，然后抽真空除气泡制得抗流挂聚氨酯防水涂料。
本发明的有益效果在于：（1）采用E-51环氧树脂对聚醚多元醇混合物进行接枝改性，提高了涂料体系的黏度；（2）改性的固体填料与聚醚具有较强的键合作用，进一步提高了其抗沉降和抗流挂性能；（3）本发明制备的涂料体系通过对多种组分的改性使其工艺性能、力学性能均大大改善。
