Abstract
液体水性去污剂组合物,包括作为增稠剂和助悬剂的含有一个或多个乙酰乙酰基或氰基乙酰基的交联的碱性可溶胀聚丙烯酸酯。
Description
技术领域
本发明涉及液体水性去污剂组合物,包括作为增稠剂和助悬剂的含有一个或多个乙酰乙酰基或氰基乙酰基的交联的碱性可溶胀聚丙烯酸酯。
在表面活性剂和电解质存在的情况下,交联的含有一个或多个乙酰乙酰基或氰基乙酰基的碱性可溶胀聚丙烯酸酯具有高增稠能力,提供均匀和澄清溶液并且有出色的悬浮性质表现。
背景技术
已知在去污剂和化妆品工业中经常遇到的一个技术问题是得到含有表面活性剂、电解质和可能的分散固体颗粒的稳定黏稠均匀的制剂。
使用的增稠剂应该开发其增稠的能力而不负面地改变制剂的其他性质。
通常,还要求增稠剂控制组合物的整体流变,包括屈服应力值。
在液体去污剂水性组合物的领域中,增稠剂通常选自交联的聚丙烯酸和交联的丙烯酸共聚物(属于交联的碱性可溶胀聚丙烯酸酯种类)、瓜耳胶及其衍生物、淀粉及其衍生物、交联的聚氧乙烯、羧甲基纤维素、部分水解的交联的水可溶胀聚合物如部分水解的聚丙烯酰胺、缔合性聚氨酯。
通常优选部分中和为钠盐的交联的聚丙烯酸和交联的丙烯酸共聚物。
在专门的文献中,报道了很多方法来调节不同制剂的流变性质,包括在中性和碱性pH下用作增稠剂的交联的丙烯酸共聚物的使用。
作为示例,我们引用:
-GB870,994,其揭示了在水性乳液中的甲基丙烯酸和丙烯酸C1-C4烷基酯(C1-C4alkyl acrylate)的共聚物;
-EP13836,其描述了基于(甲基)丙烯酸、C1-C4(甲基)丙烯酸酯、包括聚氧乙烯单元的选择的(甲基)丙烯酸酯、和任选的多烯键式不饱和单体的增稠剂,据称这些增稠剂对电解质的敏感性低于不使用选择的(甲基)丙烯酸酯制备的现有技术合成的增稠剂;
-US4,529,773和US4,138,381,其描述了包括缔合性单体的碱溶性乳液丙烯酸类聚合物及其使用方法;
-US6,140,438,其描述了在特定交联剂存在下,通过丙烯酸类单体聚合得到的具有高增稠性和悬浮性质的交联的丙烯酸类聚合物;
-EP1272159,其描述了一般不含(如含有低于约1重量%)的缔合性单体的交联的丙烯酸酯共聚物的使用。
发明内容
按照本发明制备的液体水性去污剂组合物包括:
i)0.2-10重量%、优选0.5-8重量%的增稠剂,其是通过以下聚合得到的交联的碱性可溶胀聚丙烯酸酯:
a)20-70重量%、优选20-50重量%的含有羧基的单烯键式不饱和单体;
b)20-70重量%、优选40-70重量%的(甲基)丙烯酸酯;
c)0.05-3重量%、优选0.1-2重量%的含有一个或多个乙酰乙酰基或氰基乙酰基的不饱和单体;
d)0.01-3重量%、优选0.02-1重量%的多烯键式不饱和单体;
e)0-10重量%的非离子型丙烯酸类缔合性单体;
ii)5-60重量%、优选5-20重量%的去污剂组分,其包括至少一种选自阴离子型表面活性剂、两性表面活性剂、阳离子型表面活性剂、两性离子表面活性剂、非离子型表面活性剂及其混合物的化合物。
上述交联的碱性可溶胀聚丙烯酸酯已证明在电解质和表面活性剂存在下有效发挥增稠剂的作用并且与现有技术中交联的碱性可溶胀聚丙烯酸酯相比具有改进的悬浮和增稠性质。
因此,本发明的另一个目标是上述交联的碱性可溶胀丙烯酸酯用于增稠液体水性去污剂组合物的应用,所述组合物包括5-60重量%、优选5-20重量%的上述去污剂组分。
发明详述
“去污剂组合物”表示通常用于个人洗护(个人护理去污剂,如香波和皮肤和身体清洁剂)和家用或重型(heavy duty)洗护(家用和重型洗护去污剂,如洗衣去污剂、洗盘去污剂、家用清洁剂、轻型去污剂和工业去污剂)的产品。
制备本发明的增稠剂的关键点是在单体之间存在含有一个或多个乙酰乙酰基或氰基乙酰基的不饱和单体。
乙酰乙酰基和氰基乙酰基分别具有化学式-CO-CH2-COCH3和-CO-CH2-CN。
有用的含有一个或多个乙酰乙酰基或氰基乙酰基的不饱和单体的示例是(甲基)丙烯酸乙酰乙酰氧基烷基酯、乙酰乙酸烯丙酯、乙酰乙酸乙烯酯、不饱和乙酰乙酰胺、氰基乙酸烯丙基酯(allylcyanoacetate)。
优选的含有一个或多个乙酰乙酰基或氰基乙酰基的不饱和单体是含有一个或多个乙酰乙酰基的不饱和单体。
更优选地含有一个或多个乙酰乙酰基的不饱和单体是(甲基)丙烯酸乙酰乙酰氧基烷基酯,具体是化学式为CH2=CR-CO-O-R1-O-CO-CH2-CO-CH3的(甲基)丙烯酸乙酰乙酰氧基烷基酯,其中R是H或CH3并且R1是C2-C4的直链或支链亚烷基。
最优选地,含有一个或多个乙酰乙酰基的不饱和单体是甲基丙烯酸乙酰乙酰氧基乙基酯,如化学式为CH2=CR-CO-O-R1-O-CO-CH2-CO-CH3的(甲基)丙烯酸乙酰乙酰氧基烷基酯,其中R是CH3并且R1是亚乙基。
甲基丙烯酸乙酰乙酰氧基乙基酯有一个反应活性的亚甲基基团,其在聚合物合成后可用于交联和改性聚合物。
已知反应活性的亚甲基基团能与三聚氰胺、异氰酸酯、迈克尔反应性双键(Michael reactive double bond)、醛反应。
除了反应活性的亚甲基之外,(甲基)丙烯酸乙酰乙酰氧基烷基酯还含有一个反应活性的羰基,其也经过对于树脂交联或改性有用的反应。
乙酰乙酰基化聚合物的羰基处于烯醇和酮之间的平衡形式:烯醇化使得乙酰乙酰基化聚合物与以下金属的多价阳离子螯合,如锌、锡、铝、铜、锆,以及与胺和二胺的反应。
由于这个特殊的化学性质,发现甲基丙烯酸乙酰乙酰氧基乙基酯可用作制备用于涂料、塑料和粘合剂应用的反应后可交联的聚合物的丙烯酸类单体。
如示例,US5,516,453描述了含有活性亚甲基官能组分和活性亚甲基反应活性组分的稳定的环境固化单一成分(one-pack)组合物,其可用作涂料、粘合剂和浸渍剂并且能在多种基材上使用,如木材、水泥和混凝土、织物、金属、陶瓷、塑料。
除了含有反应活性亚甲基的不饱和单体,还通过一个或多个含有羧基的单烯键式不饱和单体、一个或多个(甲基)丙烯酸酯、一个或多个多烯键式不饱和单体、以及可能的一个或多个非离子型丙烯酸类缔合性单体的共聚得到本发明的交联的碱性可溶胀聚丙烯酸酯。
丙烯酸、甲基丙烯酸、衣康酸及其混合物是所述含有羧基的单烯键式不饱和单体的示例,其可用于制备本发明的交联的碱性可溶胀聚丙烯酸酯。
甲基丙烯酸是优选的含有羧基的单烯键式不饱和单体。
有用的(甲基)丙烯酸酯是C1-C40(甲基)丙烯酸烷基酯(C1-C40(meth)acrylicacid alkyl ester),如(甲基)丙烯酸甲酯、(甲基)丙烯酸乙酯、(甲基)丙烯酸丙酯、(甲基)丙烯酸丁酯、(甲基)丙烯酸2-乙基己酯、(甲基)丙烯酸月桂酯及其混合物。
优选的(甲基)丙烯酸酯是丙烯酸乙酯。
添加多烯键式不饱和单体用作聚合物交联剂,是制备本发明增稠剂的另一个关键点。
多烯键式不饱和单体可以是任意已知的多官能衍生物,其已知与(甲基)丙烯酸单体发生自由基聚合。
在有用的多烯键式不饱和单体中,我们引用马来酸二烯丙酯、甲基丙烯酸烯丙酯、邻苯二甲酸二烯丙酯、N-亚甲基双丙烯酰胺、季戊四醇醚聚丙烯酸酯(pentaerithritol ether polyacrylates)、氰尿酸三烯丙酯(triallylcianurate)。
非离子型丙烯酸类缔合性单体可以选自(甲基)丙烯酸的C8-C30烷基酯、烷基芳基酯或聚乙二醇的多环烃基单醚的酯,其中所述聚乙二醇具有至少2个氧乙烯单元,优选具有10-40个氧乙烯单元,以及具有多至70个氧乙烯单元,该酯具有通式H2C=C(R)-CO-O(CH2CH2O)n-R’,其中
R是H或CH3,优选后者,
n至少为2,并且优选具有至少10的平均值,多至40-60或甚至多至70等等,并且R’是疏水性基团,例如:烷基,烷基芳基,或具有8-30个碳原子、优选16-18个碳原子、或更优选平均具有12-18个碳原子的多环烷基。
除了a)-e)以外的其他可用于聚合的不饱和单体是,例如,其他非离子型丙烯酸类单体、单烯键式不饱和单体(可能含有一个磺酸基)、阳离子型丙烯酸类单体。
其他可用的不饱和单体的非限制性的示例是乙酸乙烯酯、苯乙烯、氯乙烯、偏二氯乙烯、丙烯腈、(甲基)丙烯酰胺、N,N,-二甲基(甲基)丙烯酰胺、叔丁基-(甲基)丙烯酰胺、乙烯基磺酸钠、2-丙烯酰氨基-2-甲基丙磺酸。
但是,通过在聚合中仅仅使用a)-e)的单体,就得到了交联的碱性可溶胀聚丙烯酸酯在水性去污剂组合物中出色的增稠和悬浮性能。
本发明的交联的碱性可溶胀聚丙烯酸酯也能够通过以下方式间接得到:在含有羟基的不饱和单体存在下,单体a)、b)、d)与可能的e)反应,以及得到的聚合物和市售的乙酰乙酸叔丁酯的合成后反应。
本发明的液体水性去污剂组合物的去污剂组分由阴离子型表面活性剂、两性表面活性剂、阳离子型表面活性剂、非离子型表面活性剂、两性离子表面活性剂及其混合物制成。
优选地,本发明的液体水性去污剂组合物的去污剂组分包含阴离子型表面活性剂。
按照本发明的实施方式,本发明的液体水性去污剂组合物的去污剂组分包括阴离子型表面活性剂。
阴离子型表面活性剂包括烷基和烷基醚硫酸盐;烷基磺酸盐;烷基和烷基醚磷酸盐;烷基或烷基醚磺基琥珀酸盐以及烷基和烷基醚羧酸盐或烷基聚糖苷的阴离子衍生物,如烷基聚聚糖苷的柠檬酸酯、酒石酸酯或磺基琥珀酸酯。
能够在本发明的组合物中使用的两性表面活性剂是广泛描述为脂族季铵化合物的衍生物,其中脂族取代基中的一个含有阴离子水溶性基团,如羧酸基团、磺酸基团、硫酸基团等。两性表面活性剂的示例包括椰油酰两性羧基丙酸酯(cocoamphocarboxypropionate)、椰油酰两性羧基丙酸(cocoamphocarboxy propionic acid)、椰油酰两性乙酸酯(cocoamphoacetate)、椰油酰两性二乙酸酯(cocoamphodiacetate)、月桂酰两性乙酸钠(sodium lauroamphoacetate)。

虽然现有技术已知,在存在表面活性剂的情况下,在交联的碱性可溶胀聚丙烯酸酯中引入特定缔合性单体可能增强增稠性能,但是在向含有本发明的增稠剂的水性体系中加入表面活性剂之后所观察到的增稠的显著增强与聚合物中的非离子型丙烯酸类缔合性单体的存在无关。
对于现有技术的类似的不含乙酰乙酰基或氰基乙酰基的交联的碱性可溶胀聚丙烯酸酯,没有观察到同样方式的该现象。
不仅如此,已发现甚至很小量的含有反应活性亚甲基的单体显著改善了水性去污剂组合物的悬浮性质。
按照本发明的一种优选实施方式,为了增强增稠剂的悬浮性质,在聚合中使用0.1-0.5重量%的含有一个或多个乙酰乙酰基或氰基乙酰基的不饱和单体,还有1.0-2.0重量%的非离子型缔合性单体。
较佳地,本发明的水性液体去污剂组合物中增稠剂的反应活性亚甲基在存在几种常规的去污剂组合物添加剂如防腐剂(具体是甲醛或甲醛供体)和多价金属阳离子的情况下,可以进一步向聚合物提供可调的增粘性质。
在聚合物和添加剂中反应活性亚甲基的量和种类可用于调节最终水性液体组合物的粘度,这可由本领域技术人员通过少量实验容易地确定。
本发明的交联的碱性可溶胀聚丙烯酸酯可以任意常规方式制备,例如,通过沉淀聚合、悬浮液和溶液聚合、乳液聚合。通常本发明的交联的碱性可溶胀聚丙烯酸酯通过乳液聚合制备。
乳液聚合技术是本领域众所周知的,例如参见美国专利第4,325,856号;第4,654,397号;以及第4,814,373号。在乳液聚合中可以使用常规的表面活性剂,例如阴离子型和/或非离子型乳化剂,如碱金属或铵的烷基硫酸盐、烷基磺酸、脂肪酸,以及乙氧基化的烷基苯酚。以全部单体的重量为基准计,表面活性剂的用量通常为0.1-6重量%。可以使用热引发法或氧化还原引发法。可以采用常规的自由基引发剂,例如:过氧化氢,叔丁基过氧化氢或叔戊基过氧化氢,碱金属或铵的过硫酸盐,和偶氮引发剂如4,4′-偶氮二(4-氰基戊酸)、和2,2′-偶氮二异丁腈(“AIBN”),以全部单体的重量为基准计,所述自由基引发剂的含量通常为0.01-3.0重量%。使用相同引发剂和合适还原剂(例如甲醛合次硫酸氢钠、连二亚硫酸钠、异抗环血酸、硫酸羟胺和亚硫酸氢钠)的组合的氧化还原体系可以类似的含量使用,任选地与金属离子如铁和铜组合,任选地还包含金属的络合剂。可以使用硫醇之类的链转移剂,以降低聚合物的分子量。单体混合物可以以纯的形式加入,或者以水乳液的形式加入。所述单体混合物可以一次性加入或多次加入,或在反应过程中使用均匀或变化的组合物连续加入。乳液聚合过程可使用预先形成的晶种乳液聚合物,例如,通过向反应釜加入5%(以全部单体为基准计)的单体混合物并使其提前反应。可以使用减少残留单体的技术,例如,使反应混合物经蒸汽汽提、保持时间、和另外的自由基源。
本发明的交联的碱性可溶胀聚丙烯酸酯通常以酸形式、乳液形式或固态形式提供;由于其含有酸性基团,它们需要被中和成盐的形式以在水性去污剂组合物中产生最佳的粘度增加。
通常,洗衣去污剂和很多家用清洁剂具有中性-碱性的pH值;结果是本发明的水性去污剂组合物通常可通过用酸性乳液简单稀释交联的碱性可溶胀聚丙烯酸酯或通过在接近中性或碱性的水性溶液中溶解固态的交联的碱性可溶胀聚丙烯酸酯,同时伴随着加入去污剂组分和任意最优成分制备。
表面活性剂是所述水性去污剂组合物的必需成分,可以在交联的碱性可溶胀聚丙烯酸酯之后或之前加入所述表面活性剂,但是优选在交联的碱性可溶胀聚丙烯酸酯之后加入;如果需要,为了中和交联的碱性可溶胀聚丙烯酸酯,通常使用高扩散的碱性物质,如氢氧化钠或氢氧化钾、乙醇胺、氨等。
然后,在合适的时间或方式下,在对粘度水平没有显著损害的情况下,通常可用弱有机酸,如柠檬酸、水杨酸等,使得到的增稠的组合物的pH下降。
本发明的液体水性去污剂组合物的另外成分为本领域熟知,例如,可以选自香水、染料、珠光剂、遮光剂、酶、防腐剂、消毒剂、抗再沉积助剂、沸石助洗剂、磷酸盐助洗剂、抗微生物添加剂、起泡剂、消泡剂、湿润剂、调节剂、去污物剂(soil release agent)、增亮剂、溶剂和pH缓冲剂。
