Abstract
本发明涉及包含至少一种吸水性聚合物和至少一种取代的硫代磷酰胺的防味吸水性组合物,涉及它们的制备方法以及卫生制品及其生产。
Description
本发明涉及包含至少一种吸水性聚合物和至少一种取代的硫代磷酰胺的防味吸水性组合物,涉及它们的制备方法以及卫生制品及其生产。
本发明的其他实施方案可由权力要求、说明书和实施例中看出。应当理解不偏离本发明的范围上文提到的和将在下文更特别描述的本发明的主题特征不仅可应用于所指出的具体组合,也可应用于其他组合。
吸水性聚合物尤其为(共)聚合的亲水性单体的聚合物,一种或多种亲水性单体在适合的接枝基上的接枝(共)聚合物,纤维素或淀粉的交联醚,交联的羧甲基纤维素,部分交联的聚氧化烯或可溶胀于含水流体的天然产物例如瓜耳胶衍生物,优选基于部分中和的丙烯酸的吸水性聚合物。这种聚合物作为可吸收水溶液的产物用于生产尿布、棉塞、卫生巾、失禁产品和其他卫生制品,还作为保水剂用于商品蔬菜种植业。
在使用期间不愉悦的气味例如可通过脲的分解而在卫生制品中出现。WO-A-98/26808、WO-A-03/053486、EP-A-0 739 635、EP-A-1 034 800和EP-A-1 214 878对该问题提出各种办法。
WO-A-98/26808描述了包含吸收流体的材料,吸味材料以及一种或多种来自抗生物剂、脲酶抑制剂和pH调节剂的物质。
WO-A-03/053486公开了丝兰提取物作为脲酶抑制剂的用途。
EP-A-0 739 635描述了包含硼酸盐的吸收剂组合物。
EP-A-1 034 800描述了吸味剂和氧化剂的组合控制不愉悦的气味的用途。
EP-A-1 214 878教导了金属螯合物作为脲酶抑制剂的用途。
本发明的目的是提供已被尿或其他体液损伤而可靠地防止不愉悦气味的改善的吸水性组合物。由于抗生物剂的使用直接与皮肤接触有问题,组合物必须不包含任何显著的杀生物作用。
本发明的另外目的是提供储存稳定,即在长期储存中不会褪色也不会失去它们的防味效果的防味吸水性组合物。
我们发现此目的通过包含至少一种吸水性聚合物和至少一种式(I)的取代的硫代磷酰胺的组合物实现:
其中R为C1-C30烷基,优选C2-C10烷基,更优选C3-C5烷基。烷基可以为支化的或非支化的。
C1-C10烷基的实例为甲基、乙基、正丙基、异丙基、正丁基、异丁基、仲丁基、叔丁基、正戊基、异戊基、正己基、异己基、正庚基、异庚基、正辛基、异辛基、正壬基、异壬基、正癸基和异癸基。最优选的烷基为正丙基和正丁基。
本发明组合物通常包含0.0001-5重量%,优选0.003-1重量%,更优选0.005-0.1重量%至少一种取代的硫代磷酰胺。
至少一种吸水性聚合物优选基于部分中和的交联丙烯酸的聚合物。
本发明组合物通常包含至少90重量%,优选至少95重量%,更优选至少99重量%至少一种吸水性聚合物。
式(I)的取代的硫代磷酰胺可例如通过硫代磷酰三氯化物与烷基胺和氨反应而得到。
取代的硫代磷酰胺的制备例如描述于US-5,770,771中。当产物在适合的溶剂如甲苯中再结晶时达到更高的纯度。
吸水性聚合物例如通过包含如下单体的单体溶液聚合得到:

吸水性聚合物通常通过单体水溶液的加聚具有或不具有水凝胶的随后粉碎而得到。适合的制备方法描述于文献中。吸水性聚合物例如可通过如下方法得到:
-在分批法或管式反应器中凝胶聚合并随后在绞肉机、挤出机或捏合机中粉碎(EP-A-0 445 619、DE-A-19 846 413),
-随着例如通过反向旋转搅拌轴连续粉碎而在捏合机中加聚(WO-A-01/38402),
-在带上加聚并随后在绞肉机、挤出机或捏合机中粉碎(DE-A-38 25366、US-6,241,928),
-乳液聚合,其产生具有相对窄凝胶粒度分布的粒状聚合物,
-通常在连续操作中预先已用单体水溶液喷雾并随后经受光聚合的机织物层的原位加聚(WO-A-02/94328、WO-A-02/94329)。
反应优选例如如WO-A-01/38402所述在捏合机中或例如如EP-A-0955 086所述在带式反应器上进行。
得到的水凝胶的酸基团通常已部分中和优选至25-85摩尔%的程度,更优选至27-80摩尔%的程度,甚至更优选至27-30摩尔%或40-75摩尔%的程度,最优选至50-65摩尔%的程度,为此可使用常规中和剂,优选碱金属氢氧化物、碱金属氧化物、碱金属碳酸盐或碱金属碳酸氢盐及其混合物。代替碱金属盐,也可使用铵盐。钠和钾特别优选作为碱金属,但最优选氢氧化钠、碳酸钠或碳酸氢钠及其混合物。中和通常通过作为水溶液或优选作为固体原料混入中和剂而实现。例如,水含量明显在50重量%以下的氢氧化钠可作为熔点为23℃以上的蜡质块存在。在这种情况下,可作为物品块或熔体在升高的温度下计量加入。
中和可在聚合之后在水凝胶步骤中进行。但也可在聚合之前通过将一部分中和剂加入单体溶液中并仅在聚合之后在水凝胶阶段中设定所需最终中和度而中和至多40摩尔%,优选10-30摩尔%,更优选15-25摩尔%酸基团。单体溶液可通过混入中和剂而中和。水凝胶可例如通过绞肉机而机械粉碎,在这种情况下,可将中和剂喷雾、泼洒或倾倒并然后小心混入。为此,得到的凝胶块可重复被绞碎以均化。优选将单体溶液中和至最终的中和度。
中和的水凝胶然后用皮带或转鼓干燥器干燥直至残余湿含量优选15重量%以下,尤其是10重量%以下,水含量通过EDANA(EuropeanDisposables and Nonwovens Association)推荐测试方法No.430.2-02“Moisture content”测定。选择性地,干燥也可使用流化床干燥器或加热犁头混合机进行。为得到特别白的产物,有利的是通过确保蒸发水的快速除去而干燥该凝胶。为此,必须使干燥器温度最佳化,必须控制供气和除去,必须始终确保充分通风。干燥自然更加简单-且产物更加白-当凝胶的固体含量尽可能高时。在干燥之前凝胶的固体含量因此优选30-80重量%。特别有利的是用氮气或一些其他非氧化惰性气体使干燥器通风。然而,选择性地,仅简单的氧分压可在干燥期间降低以防止氧化变黄过程。但在通常的充分通风和水蒸汽除去将同样仍导致可接受的产物。非常短的干燥时间通常对于颜色和产物质量有利。
将干燥的水凝胶优选磨碎并筛分,有用的研磨设备通常包括辊磨机、钉式粉碎机或摆动粉碎机。筛分的干水凝胶的粒度优选1000μm以下,更优选900μm以下,最优选85μm以下,并且优选80μm以上,更优选90μm以上,最优选100μm以上。

然后将基础聚合物优选表面后交联。有用的后交联剂为包含两个或多个能与水凝胶的羧酸酯基团形成共价键的基团的化合物。适合的化合物例如为烷氧基甲硅烷基化合物、聚氮丙啶、聚胺、聚酰胺胺、二环氧化物或聚环氧化物,如EP-A-0 083 022、EP-A-543 303和EP-A-937 736所述,二官能醇或多官能醇,如DE-C-33 14 019、DE-C-35 23 617和EP-A-450 922所述,或β-羟基烷基酰胺,如DE-A-102 04 938和US-6,239,230所述。
有用的表面后交联剂另外包括DE-A-40 20 780的环状碳酸盐,DE-A-198 07 502的2-唑烷酮及其衍生物,例如2-羟基乙基-2-唑烷酮,DE-A-198 07 992的双-2-唑烷酮和聚-2-唑烷酮,DE-A-198 54 573的2-氧代四氢-1,3-嗪及其衍生物,DE-A-198 54 574的N-酰基-2-唑烷酮,DE-A-102 04 937的环状脲,DE-A-103 34 584的双环酰胺缩醛,EP-A-1 199 327的氧杂环丁烷和环状脲,WO-A-03/031482的吗啉-2,3-二酮及其衍生物。
对于表面后交联有利的是使用多价阳离子以及表面后交联剂。有用的多价阳离子例如包括二价阳离子如锌、镁、钙和锶的阳离子,三价阳离子如铝、铁、铬、稀土和锰的阳离子,四价阳离子如钛和锆的阳离子。可能的抗衡离子为氯、溴、硫酸根、硫酸氢根、碳酸根、碳酸氢根、硝酸根、磷酸根、磷酸氢根、磷酸二氢根和羧酸根如乙酸根和乳酸根。优选硫酸铝。
后交联通常通过将表面后交联剂的溶液喷雾在水凝胶或干聚合物基粉末上而进行。表面后交联剂和多价阳离子可以以共同溶液或作为分离溶液而喷雾。喷雾之后,将聚合物粉末热干燥,交联反应不仅可在干燥之前而且可在干燥期间进行。
用交联剂溶液喷雾优选在具有移动混合工具的混合机如螺旋混合机、桨式混合机、盘式混合机、犁头混合机和铲式混合机中进行。特别优选立式混合机,非常特别优选犁头混合机和铲式混合机。有用的混合机例如包括Ldige混合机、Bepex混合机、Nauta混合机、Processall混合机和Schugi混合机。非常特别优选使用高速混合机,例如Schuggi-Flexomix或Turbolizer型。
优选接触干燥器,更优选铲式干燥器,最优选盘式干燥器作为进行热干燥的设备。有用的干燥器例如包括Bepex干燥器和Nara干燥器。也可使用流化床干燥器。
干燥可在混合机自身中通过加热夹套或引入暖空气流而进行。可类似地使用下游干燥器,例如塔板干燥器、旋转管式炉或可加热螺杆。但也可例如使用共沸蒸馏作为干燥方法。
优选的干燥温度为50-250℃,优选50-200℃,更优选50-150℃。在此温度下在反应混合机或干燥器中的优选停留时间为30分钟以下,更优选10分钟以下。
