Description

一种改进型涂料合成方法
技术领域
本发明涉及有机涂料合成技术领域，尤其涉及一种改进型涂料合成方法。
背景技术
随着环保法规的逐渐加强,低VOC(甚至零VOC)、无毒、无污染的新材料水性聚氨酯越来越受人们的重视。水性聚氨酯广泛应用于粘接剂、涂料、纺织、印染、制革等工业领域。但未经改性的水性聚氨酯乳液存在耐水性差、机械强度不够等缺点,较大程度上限制了其应用领域。有机硅化合物是一种特殊高分子化合物,它们兼有无机化合物和有机化合物的特性,具有耐低温、耐老化、憎水、耐有机溶剂,耐辐射等许多优异性能,而且有机硅化合物还能赋予涂层杰出柔软性和爽滑性,有丝绸手感或蜡感。环氧树酯(EP)具有许多优良的性能、机械强度高,粘附力强,成型收缩率低,化学性能稳定。
目前,含有氨基的有机硅氧烷改性水性聚氨酯主要有两种方法,一种是在合成过程中将氨基硅油引入聚氨酯链段中,但由于氨基硅油突出的反应活性以及与聚氨酯溶解度的差异,所以聚合反应都需要在溶剂的存在下进行,存在环境污染问题,使它们的应用受到限制；另一种是在预聚体乳化的过程中扩链引入氨基硅油。氨基硅油改性的水性聚氨酯能形成稳定的乳液,有利于实际的应用,所得涂膜耐水性、表面疏水性等性能都有明显提高,而材料的力学性能并没有太大改变。
发明内容
本发明所要解决的技术问题是提供一种方法简单、成本低廉，重复性好，获得的环氧树脂用KH550开环改性水性聚氨酯涂料性能稳定、分散性好的合成方法。
本发明解决上述技术问题的技术方案如下：一种改进型涂料合成方法，包括如下步骤：
在干燥氮气的保护下,将KH550和环氧树脂按计量加入四口瓶烧瓶中,混合均匀后常温反应,得到组分A；
在干燥氮气的保护下,将真空脱水后的聚醚、组分A与IPDI按计量加入三口烧瓶中；
再加入计量好的一缩二乙二醇、TMP作交联剂、DM-PA、丙酮和几滴催化剂反应后出料；
将预聚体用三乙胺中和加水进行高速乳化,然后加入乙二胺稀释液反应,得到水性聚氨酯乳液；
将乳液减压蒸馏脱出丙酮即得环氧树脂用KH550开环改性水性聚氨酯涂料。
在上述技术方案的基础上，本发明还可以做如下改进。
进一步，所述在干燥氮气的保护下,将KH550和环氧树脂按计量加入四口瓶烧瓶中,混合均匀后常温反应,得到组分A步骤的具体实现如下：
在干燥氮气的保护下,将KH550和环氧树脂按计量加入四口瓶烧瓶中,混合均匀后常温反应1～5h,得到组分A。
进一步，所述在干燥氮气的保护下,将真空脱水后的聚醚、组分A与IPDI按计量加入三口烧瓶中步骤的具体实现如下：
在干燥氮气的保护下,将真空脱水后的聚醚、组分A与IPDI按计量加入三口烧瓶中，升温至85～90℃，反应1～2h。
进一步，所述再加入计量好的一缩二乙二醇、TMP作交联剂、DM-PA、丙酮和几滴催化剂反应后出料步骤的具体实现如下：
再加入计量好的一缩二乙二醇、TMP作交联剂、DM-PA、丙酮和几滴催化剂，在60～70℃条件下反应1～6h后，冷却到40～10℃出料。
