本发明涉及含氟代脂族基和羧基端基的聚硅氧烷,其制备方法以及在赋予纤维状基材诸如皮革斥水性,斥油性,抗污性及手感柔软性上的用途,并涉及经其处理后所得的基材。
Description
本发明涉及含氟代脂族和羧端基的聚硅氧烷,其制备方法,及其在赋予纤维状基材诸如皮革斥水性、斥油性、抗污性和手感柔软的用途,并涉及所得的处理过的基材。
近年来,皮革的式样一般转向全粒面革,这类皮革摸上去觉得柔软,即具有“柔软手感”。全粒面革未用涂层保护。它比饰面革或涂层革更难以保养。为了便于保养全粒皮革以及绒面革,可采用氟化学处理。
一般说来,是在皮革鞣制过程的最后工序以喷涂处理或湿处理方式(所谓的“转鼓处理”)施加氟化学处理。转鼓涂敷法常常是优选的,因为用转鼓处理作氟化学保护的持久性要比用喷涂处理好。已知的氟化学鼓式处理的主要缺点是,皮革的手感或柔软性受到不利的影响,氟化学处理使得皮革手感粗糙,干燥。已经提供了许多用作氟化学处理的氟化学组合物,有些是供此用途的市售商品,诸如牌号为“Scotchgard Leather Protector”。
各种专利和出版物揭示了各种用途的多种多样这类氟化学组合物,如U.S.3,462,296(Reynoldst等),3,484,281(Guenthner等),3,816,167(Schultz等),3,944,527(McGown),4,024,178(Landucci),4,190,545(Marshall等),4,215,205(Landucci)以及4,426,476(Chang),日本公开特许81-49081,Banks,R.E.编辑的″Organofluorine Chemicals and theirIndus-trial Applications″,226-230页(EllisHarwood,Led.WestSussex,England,1979)。还有许多专利揭示了尤其含各种氟化合物的地毯处理组合物如U.S.3,923,715(Dettre等),4,043,964(Sher-man等),4,107,055(Sukomick等),4,264,484(Patel),Re30,337(Loudas),4,388,372(Champaneria)以及4,325,857(Champaneria)。又有很多专利和出版物揭示了氟化学组合物在皮革上的用途,如U.S.4,525,305(Patel),4,920,190(Lina等),4,782,175(Wehowsky等),4,778,915(Lina等),4,539,006(Langford),3,923,715(Dettre等),4,709,074(Bathelt等)以及L.Schlossser“Eigenschaffen fluororganischer Verbindungen und ihreAnwendung auf dem Ledergebiet”Das LEDER,41Jahrgang August 1990,1q49~153页。
硅氧烷或聚合的硅氧烷诸如工业上现有的聚有机硅氧烷(如聚甲基硅氧烷),也已知能赋予皮革、织物,和纸张斥水性。可参见例如“Chemistry and Technology of Silicones”(Walter Noll,AeademicPrss,New York,P.585-603(1968))。
欧洲专利申请299 596 A2叙述了基于羧基改性有机聚硅氧烷微滴乳液的纤维处理组合物,每个聚硅氧烷分子含有至少二个羧基,采用该组合物可处理天然纤维诸如羊毛、丝或棉花。这种羧基改性有机聚硅氧烷的通式为A(R2SiO2)x(RASiO2)yR2SiA,式中R不单价烃基,A可以尤其是取代的烷基诸如3,3,3-三氟丙基或具有式R′COOH的羧基,式中R′是二价有机基,x=0~2000,y为0~200,x+y=350~2000。这种有机聚硅氧烷被说成是具有使纤维状材料有持久柔软性,平滑性,抗起皱性及压缩复原性而不产生油点的功能。
欧洲专利申请298 364 A2叙述了含氟和聚硅氧烷的聚氨酸以及它们在提供皮革斥油性,斥水性以及柔软手感上的用途。这种聚氨酯的制法为,用氟代醇异氰酸酯加合物同一种聚硅氧烷以摩尔比1~2,温度为30~130℃下反应。具有类似性能的含全氟脂族基的聚氨酯,在DE-38 02 633 A1中也有介绍。
US.4,625,010谈到了含SiC键合环氧基的有机聚硅氧烷的用途,它可以同种含全氟烷基的聚合物一起涂敷到纤维上。
US.4,098,742(Mueller)介绍了某些聚氨酯的制备方法,该聚氨酯含有至少一个来自全氟烷基取代二元醇的链段以及至少一个来自含活性氢的聚硅氧烷的链段,它们可通过有机二元化合物共缩聚合成得到,尤其对纤维,它们能赋予高度的斥油性和斥水性。

欧洲专利73,732中介绍了可使用的其它适用的碱。
本发明的聚硅氧烷宜制成浓的含水溶液或含水乳液。一般说来,本发明的含水的聚硅氧烷溶液或分散液含有约5~50%(重量)的活性组合物。在它们加入鞣制转鼓之前,本发明的聚硅氧烷在该状态易于用水稀释。
为了制备本发明的浓聚硅氧烷溶液,可以采用环境容许的水相溶性有机溶剂,诸如危险性不大的或毒性低的溶剂,如按照德国大气排放管理条例(TA-Luft)分类入II类和III类的溶剂。可用来制备本发明含水的聚硅氧烷溶液的适用的有机溶剂是至少部分水相溶性的溶剂,如醇,酮或水相溶性的醚(如二甘醇二乙醚,二甘醇二甲醚),水相溶性的乙二醇醚(如丙二醇单甲醚,丙二醇单乙醚,丙二醇单丙醚、丙二醇单丁醚,乙二醇单丁醚,二丙二醇单甲醚,二丙二醇双甲醚,二甘醇单丁醚),乙二醇或丙二醇单烷基醚的低酯(如丙二醇单甲醚醋酸酯),其中很多从市场上可以买到。
可采用有机溶剂的混合物来制备本发明的含水的聚硅氧烷溶液。
按照本发明涂敷到基材上的本发明聚硅氧烷的量要选择使其给予基材表面足够高的或合乎要求的斥水性和斥油性,该用量通常要使处理过的基材上含有0.01~5%(重量)的氟,又以0.05~2%为更佳。足以给予所要求的排斥性和手感柔软性的用量可凭经验确定,并可随需要或要求增加用量。
本发明的含氟代脂族基和羧基的聚硅氧烷尤其适用于赋予皮革斥水性,斥油性及抗污性和手感柔软性。这些性能可以通过皮革鞣制过程期间转鼓处理获得。
可向本发明的聚硅氧烷里加入各种各样助剂以给予特殊的性能,例如可以添加烃增量剂以提供抗污性或斥水性;还可以加入加油乳液或合成鞣制剂。另外可向组合物里添加其它斥油和斥水的含氟化合物,以提高本发明的组合物赋予处理过的纤维状多孔物质达到所要求的表面性能的能力。
下面的非限制性实施例中,例证性地说明了本发明的目的和优点,其中除非另行说明,所有的份数和百分数均用重量表示。在这些用本发明的聚硅氧烷涂敷在各种基材上的实施例中,采用以下的测试方法作评估。喷射等级
处理过的基材的喷射等级(SR)是一个数值,它表示出处理过的基材对冲击其表面的水诸如暴风雨中外衣遭遇到的情况所具有的动态排水性。
采用1977年公布的“Technical Manual and Yearbookof the American Association of Textile Chemistsand Colorists(AATCC)”,Standard Rest Number22测定该等级,并以测试基材的“喷射等级”来表示。它通过将水喷射在基材上测得,并用0~100的标度来度量,其中100是可能的最高等级。一般说来,喷射等级≥70是合乎要求的。斥油性
处理过的基材的斥油性(OR)采用“American Associationof Textile Chemists and Colorists(AATCC)”StandardTest Method No118-1983进行测定,该试验是基于处理过的基材耐不同表面张力油的渗透性。仅耐NujolTM矿物油(渗透性最差的测试油)的处理过的基材给出的等级为1,而耐正庚烷(渗透性最强的测试油)的处理过的基材给出的等级为8。其它中间等级值采用别的纯油或混合油加以测定,如下表所示。
标准试验液
AATCC斥油性等级数 | 组合物 |
12345678 | Nujol TM矿物油65:35 NujolTM:十六烷在70°F(21℃)的体积比n-正十六烷n-正十四烷n-正十二烷n-正—癸烷n-正辛烷n-正庚烷 |
标称的斥油性表示渗透性最强的油(或混合油)在同测试基材接触30秒钟后并不渗入或润湿基材。
一般说来,斥油性最低限度为1是合乎要求的。斥水性
采用水—异丙醇测试液测定处理过的基材的斥水性(WR),并用处理过的基材的“WR”等级来表示。仅耐渗透性最差的测试液(100%水-0%异丙醇液)的处理过的基材给出的等级为0,而耐渗透性最强的测试混合物(0%水-100%异丙醇测试液)的处理过的基材给出的等级为10。其它中间值采用另外的水—异丙醇测试液测定,该测试液中水和异丙醇的百分量各是10的倍数。WR标称值表示渗透性最强的测试液在同基材表面接触15秒钟后并不渗入或润湿基材。
一般说来,斥水性等级为2或大于2是合乎要求的。Bally渗透仪
为测试鞋面革的斥水性,采用一台5023型Bally渗透仪(一种鞋面革用的标准化动态测试机)。该试验中,测试片被机器交替压弯和拉伸,好像鞋面革实际使用时的情景,与此同时,使测试片的一面同水接触。该试验中测得的值是:
1.直到水首次从处理过的皮革的测试片的一面渗透到另一面的时间(该时间对未处理过的皮革一般不到15分钟),
2.由于试片在测度期间吸水引起的重量百分数的增加(该增加量对未处理过的皮革经一小时后一般大于100%。磨损后的斥油性和斥水性
用5cm×12.5cm处理过的基材经磨损的试片测定其排斥性,该处理过的基材已经在AATCC(CM-1型)上用砂纸在5秒钟内前后磨擦了10次,砂纸的型号为“WETORDRY-TRI-M-ITE”No600C。对磨损后的试片进行上述OR和WR排斥性试验,排斥性等级被表示成磨损后的斥油性(AOR)和摩损后的斥水性(AWR)值。静态吸油性
静态吸油性是一项设计成能度量转鼓处理的皮革在静态条件下抗油吸收程度的试验。称重一块50×50mm的试片并垂直固定在一只放有NujolTM矿物油的烧杯中,使试片的上部边缘在油面下6mm的位置。浸10分钟后,取出试片,用吸液纸轻轻抹去面上的油并重新称重。
结果用下式表示成吸油的百分数: 式中W1是试片的起始重量,W2是试片浸泡后的重量。实施例1

这种通式结构是用傅里叶变换红外光谱仪表明。实施例2-6

在一只三颈玻璃反应烧瓶中装入7.50克α,ω-丁二酸酐聚二甲基硅氧烷(1.03毫克当量/克酐,Wacker Chemie公司以SLM50240/4的牌号出售),4.36克N-乙基磺酰胺N-(2-氨乙基)-全氟辛烷磺酰胺。加热烧瓶中的物料,在65℃保持4小时,在此之后4小时,从傅里叶变换红外谱图1789cm-1位置没有发现残留的酐的吸收峰,表明反应已完成。使反应产物冷却到40℃之后,加入0.75克三乙胺以中和羧酸,将混合产物再搅拌10分钟。然后用24.0克乙二醇单丁醚和24.0克无离子水稀释本发明的α,ω-氟代脂族和羧基取代的聚二甲基硅氧烷。该烯释作用导致生成20.8%(重量)的略粘的本发明的聚硅氧烷溶液。该溶液的pH为8。实施例16
在一只玻璃反应烧瓶中装入15.0克α,ω-丁二酸酐聚二甲基硅氧烷(1.03毫克当量/克酐,Wacker Chemic公司产,牌号为SLM50240/4),9.0克C10F21CH2CH2SH,1.5克三乙胺和10.0克丙酮。封闭该反应烧瓶,加热其中的物料,并在80℃保持4小时,在此4小时之后,傅里叶变换红外光谱图1789cm-1未显示有残留的酐吸收峰,而发现在1695cm-1位置有典型的硫酯吸收峰。冷却混合产物并用92.0克丙酮稀释。这导致产生20%(重量)的本发明的聚硅氧烷溶液。实施例17
将15克实施例1制得的未稀释的脱除甲苯的聚硅氧烷产物用22.5克乙酸乙酯稀释,导致产生40%(重量)的聚硅氧烷溶液(“溶液A”)。
将55克无离子水同5克乙二醇和3.0克25%氨水混合,制成一种溶液(“溶液B”)。
加热溶液A和B到50℃并在用力搅拌下倒在一起,然后用超声波处理所得混合物6分钟,此后,在55℃用真空蒸馏脱去混合物中的乙酸乙酯。全部脱除完毕后,制得储存稳定的pH为7的微滴乳液。该分散液含有20%(重量)的本发明的聚硅氧烷。实施例18~29和对照实施例1-2
制备本发明的含氟代脂族基聚硅氧烷的含水分散液或溶液并评估它们在处理皮革(特别适用于家具革)使其具有满意的表面性能的效果。实施例1~4,7~14的聚硅氧烷是供此用途使用的。为对照起见,制备两种别的组合物。一种(对照实施例1)是U.S.4,160,777(LoudAS)权利要求3公开的产物,另一种(对照实施例2)是U.S.4,525,305第7页式IX的产物。在一种槽式排液处理中将这些处理组合物涂敷到皮革上。该产物是在加工家具革所采用的标准铬鞣,复鞣,染色及乳液加油各道工序之后的最终皮革湿法生产工序期间涂敷的。
将处理组合物加入乳液加油槽中,其用量足以提供占被修整的皮革重量1.6%的聚硅氧烷固体量。乳液加油槽含有的水溶液,其中的水合计为被修整的皮革重量的200%。
槽温为50℃,在添加处理剂的时刻pH为4.5。排液过程持续30分钟,此后用甲酸使pH降低到3.5。
处理后的皮革按常规方法干燥和修整之后,在皮革的粒面进行OR,WR,SR,AOR,AWR试验。结果列于表IV。

实施例18~21表明,可以采用各种各样的硅氧烷链长。实施例22-26证实,可以采用品种繁多的共熔剂来制备本发明的聚硅氧烷。实施例27-29表明,可以采用种种的碱来制备本发明的聚硅氧烷。实施例30和对照实施例3
