Abstract
本发明涉及一种化合物，其包含具有由结构I表示的疏水性片段的疏水改性聚(氧化烯‑氨基甲酸酯)：其中Ar1、Ar2；R1、m和n定义于本文中。本发明化合物提供含有疏水改性聚(氧化烯‑氨基甲酸酯)流变改性剂，更确切地说HEUR流变改性剂的油漆在着色后的粘度稳定性。
Description
技术领域
本发明涉及用芳基醚烷氧基化物嵌段共聚物封端的环氧烷聚合物，其适用于改进着色涂料配制物的粘度保持力。
背景技术
因为疏水改性环氧烷聚合物，更确切地说疏水改性环氧乙烷氨基甲酸酯聚合物(HEUR)提供良好流动性和耐垂挂性的组合，所以其为用于油漆的优选流变改性剂。然而，标准HEUR长期存在的缺点为，在添加着色剂时，HEUR增稠油漆的粘度典型地显著降低。这种非所期望的效果对于中度和深度着色油漆而言尤其麻烦。粘度损失使得油漆太“稀”，并且确切地说，耐垂挂性变得不可接受地低，引起其在墙面上流淌和滴落，和/或非常差的辊点画图案。因此，找到在添加着色剂后具有改进的粘度保持力的含HEUR的油漆配制物将为着色油漆领域中的一项进步。

实例6.制备氨基聚芳基烷氧基化HEUR
在真空中在间歇熔融反应器中，将CARBOWAXTM8000聚乙二醇(PEG；1200g)加热到110℃维持2小时。然后将丁基化羟基甲苯(BHT，0.132g)和Desmodur W(114.9g)添加到反应器中并且搅拌反应混合物5分钟。然后将辛酸铋(28％Bi，3.0g)添加到反应器中，并且在110℃下搅拌所得混合物10分钟。然后将中间物实例5(554.95g)添加到反应器中并且在110℃下搅拌所得混合物10分钟。将所得熔融聚合物从反应器中移出并冷却。通过将聚合物溶解于具有葡糖酸的水中来制备水性增稠剂组合物。表2为未增稠的着色基底油漆配制物，即无着色剂和HEUR流变改性剂的油漆的配方。
表2-未增稠的着色基底油漆配制物
RHOPLEX和ACRYSOL均是陶氏化学公司或其附属公司的商标。
油漆着色数据
表3a和3b说明深色基底油漆配制物的KU粘度，所述油漆配制物如表2中所描述而制备，并且分别用市售HEUR(ACRYSOLTMRM 995流变改性剂(RM-995)，一种陶氏化学公司或其附属公司的商标或本发明HEUR来增稠，和随后用12盎司Colortrend 808炭黑着色。所有油漆均用ICI增稠剂，ACRYSOLTMRM-3030流变改性剂(RM-3030)共增稠。实验HEUR和RM-3030的量以有效的磅/100加仑(lbs/100gal)为单位。在所有油漆中使用足够的RM-3030以将油漆的稠度调节到ICI粘度在1.1到1.3泊范围内。在室温下使用布鲁克费尔德KU-1+粘度计或等效KU粘度计测量油漆的KU粘度。
表3a-用炭黑着色的HG-706配制物的KU粘度数据
表3b-用炭黑着色的HG-706配制物的KU粘度数据
ΔKU是指通过在从着色前油漆原始KU粘度减去着色KU粘度而得到的用炭黑着色后油漆的KU粘度变化。
实例1-6的油漆配制物中使用的HEUR在添加着色剂后呈现油漆KU粘度稳定性的显著改进。在添加12盎司炭黑着色剂到116盎司油漆基底中后，用RM-995增稠的油漆下降多达27个KU单位。相比而言，用HEUR实例2增稠的油漆在着色时仅下降8个KU单位，用HEUR实例4增稠的油漆在着色时仅下降4个KU单位，且用实例3HEUR增稠的油漆在着色时呈现相当恒定的KU粘度，因为KU实际上稍微增加了1.2个KU单位。
