Abstract
本发明是包含共聚物颗粒的水性分散体的组合物,所述共聚物颗粒包含a)丙烯酸酯单体的结构单元;b)酸单体;和c)式(I)的硅氧烷‑丙烯酸酯单体,其中R、R1、R2、Y和x在本文中定义。还包含如本文所述的非离子和阴离子表面活性剂的组合物可用于各种应用,所述应用的范围从建筑涂料到个人护理产品。
Description
背景技术
本发明涉及包含丙烯酸酯单体和硅氧烷-丙烯酸酯单体的结构单元的共聚物颗粒的水性分散体。本发明的组合物可用于涂层和个人护理应用。
包含用丙烯酸酯和硅氧烷基团官能化的共聚物颗粒的水性杂化胶乳组合物在涂层和化妆品应用中提供改善的性能,诸如改善的耐污性和耐溶剂性、拒水和拒油性、非生物结垢特性以及与所有丙烯酸组合物相比增加的触觉反馈。
Xiao,J.等人(Prog.Org.Coat.2018,116,1-6)和Zhang,B.等人(Appl.Surf.Sci.2007,254,452-458)报告了硅氧烷-丙烯酸杂化颗粒的聚合物分散体的制备。然而,本发明人已经示出了用于制备这些分散体的方法,以产生具有高水平凝胶和未反应单体的胶乳。高浓度凝胶的形成是工艺效率低下的强有力指标,它可导致反应器结垢并导致最终涂层的性质劣化。此外,这些报道的方法中的每一个方法中掺入的含硅氧烷单体的浓度显著小于10重量%,这限制了分散体的有效性。广泛接受的是,在最终分散的共聚物颗粒中实现相对高水平的掺入的含硅氧烷的单体(例如,>20重量%)导致涂层和个人护理制剂添加剂在所需性质相关的含硅氧烷的低聚物和聚合物方面表现出改进。
因此,制备用相对高浓度的含硅氧烷单体的结构单元官能化的硅氧烷-丙烯酸酯共聚物颗粒的水性分散体将是有利的。

其中R是H或CH3;
R1为H或CH3;
每个R2独立地是CH3或O-Si(CH3)3;
Y为-CH2-或-CH2CH2-;并且
x为0或1;
条件是当x为1时,R1为H;当Y为-CH2-时,R1为H;并且当Y为-CH2CH2-时,R1为CH3并且x为0;
其中所述水性分散体中所述共聚物颗粒的固含量在30重量%至55重量%的范围内,并且a)所述水性分散体的水相包含不大于1000ppm的式I的单体;或b)所述水性分散体的水相包含不大于10000ppm的凝结物;其中所述组合物还包含:
a)基于所述共聚物颗粒的重量计0.5重量%至5重量%的式II的非离子表面活性剂:
其中n为0至10;p为2至30,条件是p≥n;并且R3为直链或支链的C3-C16烷基基团;以及
b)基于所述共聚物颗粒的重量计0.5重量%至5重量%的式III的阴离子表面活性剂:
其中R4为C6-C20烷基;m为0至10;并且M为Li、Na或K。
本发明通过向具有低凝结物(凝胶)形成的胶乳颗粒中提供具有高掺入硅氧烷基单体的胶乳来解决本领域的需要。

在一个方面,BA的结构单元与MMA的结构单元的重量比在45∶55至55∶45的范围内;在另一方面,总丙烯酸酯单体(优选地BA和MMA)的结构单元与酸单体(优选地MAA)的结构单元的重量比在99.95∶0.05,更优选地99.5∶0.5至97∶3,更优选地至98∶2的范围内。

令人惊讶地发现,将式I的高水平的硅氧烷-丙烯酸酯单体有效掺入到硅氧烷-丙烯酸酯共聚物中,可以通过本发明的方法实现,而无需大体上形成凝结物(凝胶),如通过重量分析测定,以及大直径颗粒(即,如通过本文所述的单个颗粒光学感测所确定,粒径>1μm且<40μm的颗粒)。
粒度测定方法(Particle Sizing Method)
使用Malvem Zetasizer Nano ZS90测量粒度,该Malvem Zetasizer Nano ZS90使用动态光散射(DLS)、使用Zetasizer软件版本7.11以90°的散射角测量z均粒度(Dz)。使用MilliQ水(在25℃下18.2MΩ.cm)的水性溶液稀释样品分散体的液滴以实现在200-400千计数/秒(Kcp)范围内的颗粒计数。使用仪器的粒度测定方法进行粒度测量,并且通过软件计算Dz。Dz还称为基于强度的谐波平均粒度并且表达如下;
在此,Si为来自具有直径Di的颗粒i的散射强度,详细的Dz计算在ISO 22412:2017(粒度分析-动态光散射(DLS))中有所描述。
通过AccuSizer测定悬浮聚合物水平
使用AccuSizer 7000APS单颗粒光学传感器仪器(Particle Sizing Systems,PSS,an Entegris Company,Port Richey,FL)测量共聚物颗粒分散体中的悬浮聚合物的量。在MilliQ水中按质量计将共聚物颗粒分散体稀释1000倍,然后注入仪器的样品室中。实验方法应用注射样品的两级稀释,在预稀释室中的第一稀释度为21.6,并且在仪器的第二级稀释区域中的第二稀释度为78.4。在完成数据收集之后,用MilliQ水冲洗样品室,直到观察到小于200计数每毫升的基线阈值。设置采样方法以测量大约100000总计数,并且测量的粒径>1μm的颗粒被定义为悬浮聚合物。样品以一式两份运行,并且数据呈现为平均值。采集数据并使用PSS软件(版本2.3.1.6)处理。
