Abstract
本发明涉及包含第一多级聚合物颗粒和第二多级聚合物颗粒的水性分散体的水性组合物，其中该第一聚合物颗粒和该第二聚合物颗粒各自包含水吸留芯和高Tg聚合物外壳，其中该第二多级聚合物颗粒还包含叠加在该外壳上的聚合物粘结剂层。本发明的组合物可用于降低油漆配方中TiO2的载量，同时产生具有优异遮盖力和耐擦洗性的涂层。
Description
背景技术
本发明涉及遮光颜料颗粒的水性分散体。本发明的组合物可用于降低无机颜料诸如二氧化钛在油漆配方中的载量，同时保持或改善遮盖性。
二氧化钛(TiO2)由于其非常高的折射率而成为油漆工业中最常用的遮光颜料。然而，TiO2是油漆中最昂贵的组分；此外，其制造需要高能耗，并带来潜在的环境危害风险。由于世界各地的监管机构正在推动旨在为包含TiO2的产品贴上警告标签的立法，因此大幅降低消费产品诸如建筑油漆中TiO2的浓度变得更加紧迫。
在不存在TiO2的情况下，可以通过用大量增量剂代替TiO2来获得高于临界颜料体积浓度的配方，从而在油漆中实现可接受的遮光性能(遮盖力)。然而，由于可接受的不透明度是通过产生气隙来实现的，而气隙是由不足以形成有效膜的粘结剂产生，因此所得涂层的耐擦洗性差。
尽管遮光性能也可以通过添加不透明聚合物颗粒来增强，但是这些有机遮光剂提高不透明度的能力受到它们固有的较低折射率以及在高浓度下伴随的较差涂层特性的限制。因此，不透明聚合物颗粒不是TiO2的替代品；它们的使用仅限于辅助作用，以降低实现可接受的遮盖力和保持建筑涂料性能所需的TiO2载量。
因此，发现具有可接受的遮盖力和耐擦洗性能的基本上不含TiO2的着色涂料组合物将是本领域的进步。

b)聚合物外壳，该聚合物外壳具有在60℃至120℃的范围内的Tg；
其中第二多级聚合物颗粒还包含：
c)叠加在外壳上的聚合物粘结剂层，该聚合物粘结剂层具有不大于35℃的Tg并且包含至少一种单烯属不饱和单体的结构单元；
其中第一多级聚合物颗粒和第二多级聚合物颗粒中水吸留芯与外壳中的单体结构单元的重量-重量比在1:10至1:20的范围内；

Kubelka-Munk散射系数(S/mil)计算
遮盖性能通过S/mil表征如下。对于黑色释放图表上的每种油漆，使用1.5密耳Bird刮涂棒制备三个刮涂物，使用25密耳Bird刮涂棒制备一个刮涂物。使刮涂物干燥过夜。使用模板，在每个图表上用X-ACTO刀具切出3.25”x4”的矩形。使用XRite反射计在每个划线区域中收集五个重复反射率测量值。在刮涂物的五个不同区域中测量y-反射率，并记录平均y-反射率。Kubelka-Munk遮盖力值S由以下等式给出
其中X是薄膜的平均膜厚度，R是厚膜(25密耳)的平均反射率，RB是薄膜(1.5密耳)在黑色上的平均反射率。X可由膜的重量(Wpf)、干膜的密度(D)和膜面积(A)计算。3.25″X4″模板的膜面积为13in2。
耐擦洗性测量
耐擦洗性测试基于ISO 11998。在温度和湿度受控的房间中，用20密耳Dow涂覆器在黑色乙烯基擦洗图表上进行刮涂，然后干燥7天。在擦洗测试之前和之后(并且干燥过夜)对刮涂图表进行称重，以确定在进行擦洗测试之前在分析天平上的重量损失。在PacificScientific磨耗试验机上进行擦洗测试，使用0.25％DS-4作为擦洗介质，Scotch Brite7448+超细手工研磨垫作为擦洗垫。在测试之前，用软刷将擦洗介质涂抹在涂层表面上，并用擦洗介质将擦洗垫饱和至最终总质量为4g。擦洗测试进行200个循环，然后立即用水冲洗擦洗过的面板。使面板干燥过夜并将图表重新称重。然后使用重量损失计算膜厚度损失。
