Abstract
本发明涉及具有研磨表面的挠性片状基材,特征在于其可通过以下方法获得:以相对于未涂覆的干基材为至少5重量%至90重量%的量将热固性树脂的至少一种预缩合物的水溶液或水分散体应用于挠性片状基材的上表面和/或下表面上、交联预缩合物和干燥处理过的基材。
Description
本发明涉及一种具有研磨表面的挠性片状基材及其在家中和工业上作为用于清洁表面的抹布的用途。
WO 01/94436公开了制备基于三聚氰胺/甲醛缩合物的弹性泡沫的方法。在该方法中,通过加热至120-300℃使包含三聚氰胺/甲醛预缩合物、乳化剂、发泡剂、固化剂和如果合适常用添加剂的水溶液或水分散体发泡,并交联预缩合物。三聚氰胺与甲醛的摩尔比大于1∶2。其为例如1∶1.0-1∶1.9。可由此获得的开孔软质泡沫主要在建筑物和建筑物部件中用于绝热和隔音、用于机动车辆和飞机内部绝热和隔音以及例如在冷藏库中用于低温绝热。所述泡沫也用作绝热和减震包装材料,并由于交联三聚氰胺树脂的高硬度而用作轻度研磨清洁、研磨和抛光海绵。
US-B 6,713,156描述了当在其他制品上摩擦时其表面显现出研磨效果的片状基材。此类研磨基材例如通过以下方法获得:将聚合物喷雾、发泡或印刷至片状下层如非织造物或纸上,将聚合物不均匀地应用于其上并固化它们。必须快速固化聚合物,因为聚合物的不均匀应用与基材的研磨效果相关。所用聚合物组合物的最低成膜温度(MFT)大于-10℃,并包含至少一种Tg为至少0℃,一般为20-105℃的聚合物。聚合物组合物可包含至多20重量%添加剂,例如增塑剂、交联剂、淀粉、聚乙烯醇、可与甲醛热固化的化合物(例如三聚氰胺、尿素和苯酚)。用量基于非织造物和其他多孔基材一般大于20重量%,优选30-50重量%。例如将不均匀涂有聚合物的基材用作家用和工业用擦布和抹布、化妆用拭子以及用于伤口处理的药签。
US 2005/0202232公开了由至少一层片状三聚氰胺泡沫层和至少一层增强层组成的产品。提到了将来自BASF Aktiengesellschaft的用作三聚氰胺泡沫。为基于三聚氰胺/甲醛缩合物的开孔泡沫。片状三聚氰胺泡沫层和含有纤维素纤维或者天然或合成纺织纤维的相同片状增强层例如借助于热熔性粘合剂彼此结合。然而,取决于增强层的种类,它们也可例如通过热和如果合适压力的作用彼此直接结合。由于三聚氰胺泡沫层的高硬度,在家中和工业上将由此获得的在片材至少一个面上具有三聚氰胺泡沫层的产品用作用于清洁和护理表面的制品。优选这些制品为使用后即丢弃的一次性制品。一般而言,它们为厚度小于5mm,优选为0.85-2mm的布。
在家具和建筑工业中将在每种情况下均以基于尿素、三聚氰胺和甲醛缩合物的含水粘合剂或粉末出售的胶水和浸渍树脂(例如来自BASFAktiengesellschaft,67056Ludwigshafen的和)用于制备板状板基材料,例如碎料板、层压木板和模板,参见TechnischeInformation用浸渍树脂浸渍过的纸具有硬表面。此类产品例如存在于层压地板的表面或家具制品的装饰中,参见Technische Information
为提高纸的湿强度,例如在纸的制备过程中纸页成形前将三聚氰胺/甲醛树脂(例如K,BASF Aktiengesellschaft,67056Ludwigshafen)加入纸浆中。存在于纸浆中的树脂的量基于干纸浆为例如约0.5-1重量%。
使用后即丢弃的已知抹布如厨房卷纸或薄页纸稳定性不足以确保充分的擦洗效果,尤其是在湿润状态下。
在先EP申请06 116 165公开了用至少一种整理剂整理纸和纸制品的方法,其中将至少一种整理剂以图案形式应用于纸或纸制品的上表面和/或下表面上。在该方法中,与已知整理方法相比,制备具有相似性能的纸需要较少的整理剂。合适的整理剂还尤其为三聚氰胺/甲醛树脂和尿素/甲醛树脂。
本发明目的在于提供一种在家中和工业上用于清洁表面的具有研磨表面的基材。
本发明通过具有研磨表面的挠性片状基材实现了所述目的,所述挠性片状基材可通过以下方法获得:以基于未涂覆的干基材为至少5重量%至90重量%的量将热固性树脂的至少一种预缩合物的水溶液或水分散体应用于挠性片状基材的上表面和/或下表面上、交联预缩合物和干燥处理过的基材。
将研磨表面理解为指当将该表面在另一表面上移动时,对所述另一表面产生摩擦或擦洗作用。虽然例如薄页纸在使用过程中实际上没有擦洗作用,但当擦洗含有玻璃、金属或塑料的表面时本发明基材却显现出清洁这些表面所需的擦洗效果。然而,所述擦洗效果远远低于砂纸,因此本发明基材适用于其中仅需要去除灰尘所需轻微擦洗效果的所有应用,从而使用本发明基材擦洗的材料的表面实际上没有受到损伤。优选将本发明产品用作一次性制品,但也可使用多次,这取决于各自的应用。
片状基材的实例为纸、纸板、卡纸板,编织物、针织物和非织造物。纸、纸板和卡纸板可由各种纤维素纤维制备,可由天然纤维素纤维和回收纤维制备,特别是常以与原纤维的混合物使用的废纸纤维。将纤维悬浮在水中得到纸浆,在造纸网上排出纸浆中的水,同时纸页成形。用于制备纸浆的合适纤维为造纸工业上常用于该目的的各种纤维,例如机械浆、漂过和未漂的化学浆以及来自于所有一年生植物的纸浆。机械浆包括例如磨木浆、预热法机械磨木浆(TMP)、预热法木片化学机械浆(CTMP)、压力磨木浆、半化学浆、高得率浆和盘磨机械浆(RMP)。例如硫酸盐浆、亚硫酸盐浆和碱法浆是合适的化学浆。优选使用也称作未漂硫酸盐法纸浆(craft pulp)的未漂化学浆。用于制备纸浆的合适一年生植物为例如水稻、小麦、甘蔗和洋麻。构成用于本发明产品的片状基材的纸制品的基重为例如7.5-500g/m2,优选10-150g/m2,特别是10-100g/m2。特别优选的片状基材为薄页纸和具有结构化表面的纸,例如常见于家中的厨房卷纸。此类纸制品的基重例如为10-60g/m2。所用片状基材可由一层组成,或者例如通过将仍是湿的层置于另一刚刚制备好的层的上面并挤压它们,或借助于合适粘合剂使已干的各层彼此粘合结合而可由多层组成。
片状基材的厚度为例如0.01-100mm,优选0.05-10mm。其一般为0.05-3mm。片状基材例如以卷材或片材形式存在。此类材料具有挠性。即便是应用和固化热固性树脂后它们仍保持其挠性,但实际上最多以正好保持未处理过的基材的挠性的量应用所述树脂。虽然未处理过的基材的挠性由于应用热固性树脂而降低,但树脂的量为不会形成例如常见于家具饰面的硬且没有挠性的结构的量。依据本发明涂覆的纸无论如何都不可能是易碎的,且不应象玻璃那样在弯曲和折叠时破裂。依据本发明涂覆的纸板也能弯曲而不会被破坏,但与未涂覆的纸板相比其擦洗效果实际上得到了提高。
对制备具有研磨表面的挠性片状基材而言,首先用至少一种热固性树脂的预缩合物的水溶液或水分散体处理片状基材,例如非织造物、编织物、针织物、纸、纸板和卡纸板。热固性树脂的预缩合物选自三聚氰胺/甲醛预缩合物、尿素/甲醛预缩合物、尿素/乙二醛预缩合物和苯酚/甲醛预缩合物。
优选使用三聚氰胺与甲醛的预缩合物,其中三聚氰胺与甲醛的摩尔比大于1∶2。优选将其中三聚氰胺与甲醛的摩尔比为1∶1.0-1∶1.9的三聚氰胺与甲醛的预缩合物用作热固性树脂。三聚氰胺/甲醛缩合物可含有以缩合单元形式结合的至多50重量%,优选至多20重量%除三聚氰胺外的其他热固性塑料前体以及至多50重量%,一般至多20重量%除甲醛外的其他醛。合适的热固性塑料前体为例如烷基-和芳基取代的三聚氰胺、尿素、尿烷、羧酰胺、双氰胺、胍、硫酰胺、磺酰胺、脂族胺、乙二醇、苯酚和苯酚衍生物。可将乙醛、丙醛、异丁醛、正丁醛、三羟甲基乙醛、丙烯醛、苯甲醛、糠醛、乙二醛、戊二醛、邻苯二醛和对苯二醛用作醛,例如用于部分代替缩合物中的甲醛。
如果合适可使预缩合物与至少一种醇醚化。其实例为一元C1-C18醇(例如甲醇、乙醇、异丙醇、正丙醇、正丁醇、仲丁醇、异丁醇、正戊醇、环戊醇、正己醇、环己醇、正辛醇、癸醇、棕榈醇和十八烷醇)和多元醇(例如乙二醇、二甘醇、甘油、1,4-丁二醇、1,6-己二醇、具有3-20个环氧乙烷单元的聚乙二醇、一端封端的乙二醇和聚亚烷基二醇、1,2-丙二醇、1,3-丙二醇、聚丙二醇、季戊四醇和三羟甲基丙烷)。
热固性树脂的制备是现有技术的一部分,参见Ullmann工业化学百科全书(Ullmann′s Encyclopedia of Industrial Chemistry),第6版(完全修订),Wiley-VCH Verlag GmbH Co.KgaA,Weinheim,“氨基树脂”,第2卷,第537-565页(2003)。
所用原料为预缩合物的水溶液或水分散体,优选三聚氰胺与甲醛的预缩合物。固体浓度为例如5-95重量%,优选10-70重量%。预缩合物的溶液或分散体一般包含至少一种固化剂。在具体情况下,也可将常用于缩合的固化剂单独应用于片状基材上。一般将催化热固性树脂进一步缩合的酸性化合物用作固化剂。其量基于树脂为例如0.01-70重量%,优选0.05-60重量%。合适的固化剂为例如无机和有机酸(例如盐酸、硫酸、磷酸、硝酸、甲酸、乙酸、草酸、对甲苯磺酸或氨基磺酸)、酸酐(例如马来酸酐或衣康酸酐)、酸与氨或胺的盐、硫酸氢钠和氯化镁。
热固性树脂的预缩合物的水溶液或水分散体如果合适也可包含表面活性剂。例如非离子、阴离子和阳离子表面活性剂以及至少一种非离子表面活性剂与至少一种阴离子表面活性剂的混合物、至少一种非离子表面活性剂与至少一种阳离子表面活性剂的混合物、多种非离子表面活性剂或多种阳离子表面活性剂或多种阴离子表面活性剂的混合物均合适。
例如所有表面活性试剂均是合适的表面活性剂。合适非离子表面活性物质的实例为乙氧化单-、二-和三烷基酚(乙氧化度:3-50,烷基:C3-C12)和乙氧化脂肪醇(乙氧化度:3-80:烷基:C8-C36)。其实例为BASF AG的品牌或Union Carbide的品牌。特别优选以下通式的乙氧化线性脂肪醇:
n-CxH2x+1-O(CH2CH2O)y-H,
其中x为10-24的整数,优选12-20。优选变量y为5-50的整数,特别优选8-40。乙氧化线性脂肪醇一般以具有不同乙氧化度的不同乙氧化脂肪醇的混合物存在。在本发明上下文中,变量y为平均值(数均)。合适的非离子表面活性物质还可为环氧乙烷和至少一种C3-C10环氧烷烃的共聚物,特别是嵌段共聚物,例如下式的三嵌段共聚物:
RO(CH2CH2O)y1-(BO)y2-(A-O)m-(B′O)y3-(CH2CH2O)y4R′
其中m为0或1,A为衍生自脂族、环脂族或芳族二醇的基团,例如乙烷-1,2-二基、丙烷-1,3-二基、丁烷-1,4-二基、环己烷-1,4-二基、环己烷-1,2-二基或二(环己基)甲烷-4,4′-二基,B和B′彼此独立为丙烷-1,2-二基、丁烷-1,2-二基或苯基乙烷基,彼此独立为2-100的数值,y2和y3彼此独立为2-100的数值,优选y1+y2+y3+y4的和为20-400,这对应于数均分子量为1000-20 000。优选A为乙烷-1,2-二基、丙烷-1,3-二基或丁烷-1,4-二基。优选B为丙烷-1,2-二基。
除非离子表面活性剂外,其他合适的表面活性物质为阴离子表面活性剂和阳离子表面活性剂。可单独或以混合物使用它们。然而,其前提条件在于它们彼此相容,即它们不彼此沉淀。例如该前提条件适用于每种情况下的一类化合物的混合物、非离子表面活性剂与阴离子表面活性剂的混合物以及非离子表面活性剂与阳离子表面活性剂的混合物。合适阴离子表面活性试剂的实例为月桂基硫酸钠、十二烷基硫酸钠、十六烷基硫酸钠和二辛基磺基丁二酸钠。
阳离子表面活性剂的实例为四烷基铵盐,烷基苄基铵盐(例如氯化二甲基C12-C18烷基苄基铵),伯、仲和叔脂肪胺盐,季酰胺基胺化合物,烷基吡啶鎓盐,烷基咪唑啉鎓盐以及烷基噁唑啉鎓盐。
特别优选阴离子表面活性剂,例如与硫酸酯化并一般以用碱中和的形式使用的(任选烷氧化)醇。其他常用乳化剂为例如烷基磺酸钠和烷基硫酸钠,例如十二烷基硫酸钠、十二烷基苯磺酸钠和磺基丁二酸盐。此外,也可将磷酸的酯或亚磷酸的酯和脂族或芳族羧酸用作阴离子乳化剂。文献具体描述了常用乳化剂,参见例如M.Ash,I.Ash,工业表面活性剂手册(Handbook of Industrial Surfactants),第3版,Synapse InformationResources Inc。
至少一种预缩合物的水溶液或水分散体可包含至多10重量%的表面活性剂。如果其包含表面活性剂,优选存在于溶液或分散体中的表面活性剂的量为0.01-5重量%。
预缩合物的水溶液或水分散体如果合适还可包含常用添加剂,例如染料、生物杀伤剂、微粒、无机化合物(例如二氧化硅、氧化铝、碳化硅、二氧化钛、氧化锌、碳酸钙)、大理石和刚玉。无机化合物的平均粒径为例如1nm-500μm。这些添加剂的量基于溶液或分散体为例如0-100重量%,优选0-25重量%。预缩合物的水溶液或水分散体也可包含至少一种芳香剂或香料。如果使用此类物质,则量基于溶液或分散体为例如0.1-5重量%,一般为0.2-1重量%。优选本发明挠性片状基材不含在另一个表面上摩擦时显现出擦洗效果的材料如碳化硅或氧化铝。
预缩合物的水溶液或水分散体也可包含0-20重量%至少一种聚合添加剂。其实例为N-乙烯基吡咯烷酮、丙烯酰胺、甲基丙烯酰胺、丙烯酸、甲基丙烯酸以及丙烯酸和甲基丙烯酸的盐的均聚物和共聚物,聚乙酸乙烯酯,聚乙烯醇,聚氮丙啶,聚苯乙烯磺酸酯,聚苯乙烯磺酸,聚苯乙烯,含有以聚合单元形式结合的丁二烯的聚合物(例如苯乙烯和丁二烯的共聚物,苯乙烯、丁二烯和丙烯酸的共聚物,苯乙烯、丙烯腈和丁二烯的共聚物),聚丙烯腈,丙烯醛的共聚物,丙烯酸烷基酯的均聚物和共聚物,甲基丙烯酸烷基酯的均聚物和共聚物,聚酰胺,聚酯和聚甲醛。
为制备本发明产品,可在基材整个表面上应用预缩合物的溶液或分散体(下文也称作“制剂溶液”)或以图案形式将其应用于基材上。应用于片状基材前也可使制剂溶液发泡,例如通过在空气或其他气体中搅拌。固化和干燥后则获得涂有泡沫的片状基材,与含有基于三聚氰胺和甲醛的热固性树脂的已知泡沫如相反,所述泡沫的孔的平均直径为纳米级,例如1-1000nm。
优选以未发泡状态将制剂溶液应用于每种情况均合适的下层上。例如可通过喷雾、刀涂、辊涂、印刷或借助于本领域技术人员已知的其他合适工业设备(例如施胶机、压膜机(film press)、气刷或幕涂设备)将其应用于片状基材上。优选使用非接触法或对片状基材使用尽可能低的压力的方法以减少树脂吸收进入基材。
可同时或连续在一个面或两个面上进行应用。借助于制剂溶液应用于片状基材的可固化树脂的量基于未涂覆的干片状基材的基重为例如5-90重量%,优选10-80重量%,特别是20-70重量%。
因此其实际上高于造纸中通过向纸浆加入湿强剂增湿处理纸的一般用量,且实际上低于通过用三聚氰胺/甲醛树脂涂覆片状基材制备装饰板的用量。在每种情况下应用于基材的预缩合物的量对本发明产品的挠性、柔软性和手感具有决定性影响。
此外,制剂溶液或固化树脂在基材上的分布对本发明产品的挠性具有相对大的影响。例如可将制剂溶液不均匀地应用于下层上,例如所述制剂溶液覆盖下层的全部面积,但却不是均匀地分布在其上。其他变化包括以图案形式将制剂溶液印刷至片状基材上。例如如果以平行条带或点的形式将制剂溶液印刷在下层上,则由此获得挠性特别大的产品。
将制剂溶液应用于片状下层后,交联热固性树脂,并干燥提供有一层热固性树脂预缩合物的片状基材,可同时或连续进行交联和干燥。在有利的实施方案中,在潮湿气氛中交联热固性树脂,然后干燥所述产品。树脂的热固化和产品的干燥可例如在40-250℃,优选50-200℃,特别优选80-140℃的温度下进行。干燥步骤也可例如在气体干燥机或IR干燥机中进行。在每种情况下所用温度越高,待干燥材料在干燥装置中的停留时间越短。如果需要,干燥后也可在至多300℃的温度下加热本发明产品。也可将300℃以上的温度用于固化树脂,但所需停留时间则非常短。
获得在家中和工业上用作用于清洁表面的抹布的挠性片状基材。它们特别适于用作研磨抹布用于清洁含有金属、玻璃、陶瓷、塑料和木材的制品的表面。本发明产品特别适于用作一次性制品,但如果合适也可使用多次。它们可使用多次,尤其是在本发明产品含有编织物或非织造物作为下层的情况下。
除非从上下文明显可知,否则实施例所述百分数均为重量百分数。
