Abstract

辐射固化粘合剂的组合物,其包括丙烯酸类聚合物和聚烯烃,用于制造压敏粘合剂制品,例如胶带。

Description

丙烯酸热熔粘合剂
发明领域
本发明涉及辐射固化热熔组合物及其最终用途应用。
发明背景
压敏粘合剂(Pressure-sensitive adhesive(PSA))组合物用于压敏粘合带,该粘合带包括背衬和PSA组合物。
辐射固化PSA组合物,包括紫外线(UV)固化组合物——其包括UV固化聚合物和增粘树脂,一般是烃类树脂——是已知的,并在本领域应用。虽然UV固化PSA已知,但是原材料,特别是制造这种粘合剂需要使用的丙烯酸类树脂,价格昂贵。原材料的成本提高了粘合剂的成本,因此也提高了用粘合剂生产的制品的成本。虽然已经加入过量的增粘剂以降低粘合剂成本,但是增粘剂使粘合剂变弱并吸收UV辐射,导致有用的内粘性的损失。
在本领域,对于仅用有效量的增粘剂和减少量的昂贵丙烯酸类树脂配制的辐射固化热熔丙烯酸粘合剂存在需求。本发明解决了本领域的这一需求。
发明概述
本发明提供辐射固化粘合剂组合物和包括辐射固化粘合剂的PSA制品。
本发明的一种实施方式涉及辐射固化压敏粘合剂,其包括丙烯酸类聚合物和聚烯烃共聚物,并且如果希望或要求,还包括增粘树脂和/或光敏引发剂。令人惊奇的发现是,聚烯烃共聚物在辐射固化粘合剂组合物中可用作添加剂。聚烯烃共聚物的使用减少了期望粘合性所需的丙烯酸类树脂用量。
优选的丙烯酸类聚合物是UV固化丙烯酸类聚合物,其包括共价结合到光反应基团(photoreactive group)的丙烯酸类共聚物。特别优选的UV丙烯酸类共聚物包括C4至C8丙烯酸烷基酯并将其与二苯甲酮侧基结合。
本发明的另一种实施方式涉及包含如下粘合剂的制品,这种粘合剂被永久粘合到该制品的底材上,并可用于将该制品可除去地或可剥离地贴附在另一制品上。本发明的制品包括胶带、标签转移膜(labelstransfer films)和类似物,也有用作包装粘合剂。本发明包括用于黏附地粘贴于皮肤的制品如医用膏药、绷带和胶带。优选的是粘合剂制品,例如胶带、转移膜等等,其如下制备:将包括丙烯酸类聚合物和聚烯烃的辐射固化粘合剂涂布到底材表面,将应用的粘合剂暴露于辐射能一段足以固化粘合剂的时间。在一种特别优选的实施方式中,辐射固化粘合剂包括UV固化丙烯酸类聚合物、EVA和/或EnBA和增粘剂。在一种优选的实施方式中,UV固化丙烯酸类聚合物是丙烯酸-2-乙基己酯,其包括共价结合的二苯甲酮基。
发明详述
现已发现,使用辐射固化丙烯酸类聚合物和聚烯烃制备的粘合剂组合物,可用于制造压敏粘合剂制品,如胶带等。已经发现,UV透明聚烯烃共聚物的用途是可用于减少制造粘合剂产品如压敏胶带所需的丙烯酸类树脂用量。聚烯烃添加剂不干扰UV吸收或不引起粘合性的基本损失。因此,包括聚烯烃添加剂的粘合剂费用更低,原因在于在本发明的配方中可以使用少量的昂贵丙烯酸类聚合物。
以下使用的术语“热熔压敏粘合剂”或“热熔压敏粘合剂组合物”意思是这样的粘合剂或粘合剂组合物,其在通过将粘合剂或粘合剂组合物应用于基材如纸、布或塑料膜上,生产粘合性物品例如粘合带和粘合片之后,能够通过将它作为热熔体应用到基材上而在基材上形成压敏粘合剂或压敏粘合剂组合物层。
术语“压敏粘合剂”在此用于指粘弹性材料,其通过应用轻微的压力瞬间粘附于大多数底材并永久保持粘性。
在此使用的术语“增粘剂”意思是对给予热熔粘合剂组合物粘着性有用的任何组合物。ASTM D-1878-1T定义粘着性为“材料的性质,使它能够在与另一表面接触时立即形成可测量强度的结合”。
在此使用的术语“辐射固化粘合剂”意思是曝露于光化辐射和/或电离辐射后可固化的粘合剂组合物。术语“辐射”在此用于包含光化辐射如紫外线辐射和通过发射电子或高度加速的核粒子如中子和α粒子等形成的电离辐射。
用于本发明实践的辐射固化粘合剂一般包括作为基础树脂的丙烯酸类聚合物和聚烯烃。根据本发明预期固化的组合物,组合物也可以包括光敏引发剂和/或增粘剂。
可使用的光敏引发剂的实例包括一种或多种下列物质:二苯甲酮、苄基二甲基缩酮、异丙基噻吨酮、二(2,6-二甲氧基苯甲酰)(2,4,4-三甲基戊基)氧化膦、2-羟基-2-甲基-1-苯基-1-丙酮、二苯基(2,4,6-三甲基苯甲酰)膦氧化物、1-羟基环己基二苯酮、2-苄基-2-(二甲氨基)-1-4-(4-吗啉基)苯基-1-丁酮、α,α-二甲氧基-α-苯基苯乙酮、2,2-二乙氧基苯乙酮、2-甲基-1-4-(甲硫基)苯基-2-(4-吗啉基)-1-丙酮、2-羟基-1-4-(羟基乙氧基)苯基-2-甲基-1-丙酮。
一种优选的辐射固化粘合剂包括作为基础树脂的丙烯酸类聚合物。丙烯酸类聚合物的混合物或掺合物可用于本发明的实践。丙烯酸类聚合物期望可结合到光反应基团(在此指UV固化丙烯酸类聚合物)。优选的UV固化丙烯酸类聚合物包括用聚合的光反应基团改性的丙烯酸类聚合物骨架分子,例如化学键合于丙烯酸类聚合物链的改性二苯甲酮基。聚合物通过UV照射而激发光敏引发剂所导致的化学接枝进行交联。
特别优选的UV丙烯酸类共聚物包括C4至C8丙烯酸烷基酯并将其与二苯甲酮侧基结合。这样的UV固化聚合物可从BASF商业获得,商标名称为acResin

UV。这些材料无溶剂和无水丙烯酸原料,其可用于生产压敏胶带和标签。这些聚合物在室温下是高度粘性液体,并且必须加热至约120-130℃的温度,以成为流体(粘度大约为40Pas),用于纸张或塑料载体上的涂布过程。在此温度下,它们可通过常规的热熔涂布系统应用于背衬底材或载体。因此,它们可以作为热熔体来处理。在被涂布到载体上后,聚合物膜通过UV照射而交联,以产生所需的粘合性。
特别优选的UV丙烯酸类共聚物包括丙烯酸-2-乙基己酯,其已与二苯甲酮侧基结合。这种UV丙烯酸类共聚物可从BASF商业获得,商标名称为acResin

A258UV产品,包括作为主要成分的丙烯酸丁酯,也可用于本发明的实践。
其它有用的UV固化聚合物包括DS3552X,也可从BASF商业获得。
本发明的粘合剂典型地包括大约50wt%至大约80wt%的UV固化聚合物。
除了UV固化聚合物之外,本发明的粘合剂包括聚烯烃聚合物。已发现聚烯烃可以有利地作为填料,从而降低最终PSA配制物的成本。已发现乙烯共聚物与丙烯酸热熔聚合物非常相容,这很令人惊讶,因为丙烯酸聚合物具有强极性。
这种聚合物包括含半结晶或非晶态聚烯烃和乙烯的聚合物或共聚物以及其掺合物。在优选的实施方式中,粘合剂包括至少一种乙烯共聚物,并可包括两种或两种以上聚合物的掺合物。在此使用的术语“乙烯共聚物”是指乙烯的均聚物、共聚物和三元共聚物或多元共聚物。乙烯共聚物的实例包括:含有一个或多个可以与乙烯共聚的极性单体的共聚物,如乙酸乙烯酯或其它的一元酸乙烯酯,或丙烯酸或甲基丙烯酸或它们与甲醇、乙醇或其它醇的酯。包括在内的是乙烯乙酸乙烯酯、乙烯丙烯酸甲酯、乙烯丙烯酸正丁酯、乙烯丙烯酸、乙烯甲基丙烯酸酯和其混合物和掺合物。其它实例包括但不限于聚乙烯、乙烯/α-烯烃共聚体、丁烯-1/乙烯共聚物、无规立构聚丙烯、低密度聚乙烯、均匀线性乙烯/α-烯烃共聚物、乙烯丙烯酸正丁酯共聚物和乙烯乙烯酯共聚物。无规和嵌段共聚物以及其掺合物可用于本发明的实践。本发明的粘合剂将优选地包括至少一种乙烯共聚物。特别优选的实施方式包括乙烯丙烯酸正丁酯共聚物和/或乙烯乙酸乙烯酯共聚物。
聚烯烃典型的使用量为直至约50wt%,更典型为约10wt%到约30wt%。
在本发明粘合剂配方中使用聚烯烃提供更好的耐水和耐溶剂性,而且是UV可透过的,不干扰UV固化机制的自由基反应。因此,当使用本发明的粘合剂时,可获得更深的渗透和较厚膜的增加的固化时间。此外,已发现丙烯酸类树脂和聚烯烃的掺合物允许使用聚烯烃不相容的增粘树脂,例如Kristalex F85。
如上所述,聚烯烃不像常规增粘剂那样干扰UV固化机制的自由基反应。此外,已发现与常规增粘剂相比,聚烯烃更好地保持UV固化丙烯酸类聚合物的粘结强度(10-20wt%)。此外,聚烯烃的加入不会明显增加粘度。
本发明的粘合剂还优选地包括相容增粘剂。如本领域技术人员所理解的,相容增粘剂是指能够与粘合剂聚合物如丙烯酸类聚合物混合的增粘剂。在一种优选的实施方式中,增粘剂是基于松香的增粘剂,更具体地是松香酯和松香酸及其氢化形式。实例包括Foral85(Eastman),Pine Crystal KE 311(Arakawa)和Staybelite Ester10(Hercules),以及聚乙烯醚,如来自BASF的Lutonal M40等级。其它可用的增粘剂包括脂肪族和芳香族烃树脂,例如,α甲基苯乙烯树脂,其软化点低于约110℃。实例包括Kristalex3085(Kristalex F85),一种α-甲基苯乙烯树脂,其软化点约85℃,可从Eastman Chemical商业获得。
增粘剂的用量水平通常为直至40wt%,更典型的是约,优选地大约30wt%到大约20wt%。
本发明的组合物可包括本领域普通技术人员所知的其它添加剂。这些添加剂可包括但不限于:颜料、填料、荧光添加剂、流动和流平添加剂(flow and leveling additives)、润湿剂、表面活性剂、防沫剂、流变改性剂、稳定剂和抗氧化剂。其它可选的添加剂包括含有丙烯酸酯或甲基丙烯酸酯官能度的不饱和低聚物和多官能单体,如可从Sartomer获得的SR295,SR355和SR350,和另外的光敏引发剂。优选的添加剂是那些对感兴趣波长没有显著吸收的添加剂。
典型地加入抗氧化剂以在制备和使用粘合剂组合物的过程中保护成分免于降解,并确保长期的热稳定性,但不会干扰聚合物的辐射固化。
抗氧化剂的组合往往更有效,原因在于各种聚合物所经历的不同降解机制。某些受阻酚、有机金属化合物、芳香胺、芳香亚磷酸盐和硫化合物可用于此目的。这些材料有效类型的实例包括:酚抗氧化剂、硫代化合物和三(壬基化苯基)亚磷酸盐。
粘合剂组合物中一般包含按重量计达3%的一种或多种抗氧化剂。通常情况下,含量为0至约3wt%,优选地为按重量计约0.1%至约3%左右,更优选地是按重量计约0.4%至约2.0%。
可用于本发明实践的代表性抗氧化剂包括:1,3,5-三甲基2,4,6-三(3,5-二叔丁基-4-羟苄基)苯;季戊四醇-四-3(3,5-二叔丁基-4-羟基苯基)-丙酸酯;4,4′-亚甲基双(2,6-叔丁基苯酚);4,4′-硫代双(6-叔丁基-邻甲酚);2,6-二叔丁基苯酚;2-叔丁基-6-(3-叔丁基-2-羟基-5-甲基苄基)-4-甲基苯基丙烯酸酯;6-(4-羟基苯氧基)-2,4-二(正辛基硫代)-1,2,5三嗪;二-正十八烷基3,5-二叔丁基-4-羟基苄基膦酸酯;2-(正辛基硫代)乙基3,5-二叔丁基-4-羟基苯甲酸酯和山梨醇六[3-(3,5-二叔丁基-4-羟基苯基)丙酸酯]。这些化合物可从Ciba商业获得。
UV固化聚合物、聚烯烃和如果需要的话增粘剂(以及其它所需的成分,如抗氧化剂)在约130℃以上但不超过150℃的温度下掺合在一起,直到形成清澈的混合物。夹带的空气可通过应用真空来去除。
将组合物涂布到载体如纸或金属箔之后,对它进行UV照射。在UV光的作用下,UV固化聚合物里的光反应基团交联到聚合物主链。
发射UV波长的常规H灯泡和中压汞蒸气灯可用于本发明实践中固化本发明粘合剂。
本发明的压敏粘合剂可有利地用于粘合剂制品的制造,包括但不限于,工业胶带和转移膜。单和双面胶带以及负载和未负载的游离膜包括在本发明中。还包括但不限于:标签、贴花、名牌、装饰和反光材料、重新封闭的紧固件、防盗和防假冒设备。
在一种实施方式中,粘合剂制品包括粘合剂,其涂布在具有第一和第二主要表面的背衬至少一个主要表面上。可用的背衬底材包括但不限于:泡沫,金属,织物,以及各种聚合物膜,如聚丙烯、聚酰胺和聚酯。粘合剂可存在于背衬的一个或两个表面。当粘合剂涂布在背衬的两个表面时,每个表面的粘合剂可以相同或不同。
可用于本发明实践的背衬包括:改性或未改性的金属箔、金属化多层箔、含有聚四氟乙烯(
Figure G2006800545100D0007174123QIETU

压敏粘合剂在制造医疗用途制品中也有用,如造口术封条、粘合带和绷带、创伤引流粘合封条、创伤敷料、作为其它产品的附着物和类似物,其粘附于人皮肤并且即使在潮湿环境下仍保持粘附。
本发明的粘合剂也非常适合用于经皮应用。本发明的压敏粘合剂可纳入经皮给药装置,该装置被设计来向患者的皮肤递送治疗有效量的产品,如治疗皮肤刺激,或穿过患者皮肤递送治疗有效量的药物。术语“经皮”是指通过局部应用,将皮肤用作给药的入口。局部施用的药物进入皮肤和/或通过皮肤。因此,广义地,“经皮”用于指局部给药,其局部起作用,即在皮肤表面或皮肤内部起作用,诸如,例如,用于治疗痤疮的创伤贴片(blemish patch);以及指通过扩散穿过皮肤并进入血流而全身起作用的药品的局部施用。
在以下的实施例中将对本发明进一步描述,其被包括是出于说明目的,并且不意欲以任何方式限制本发明范围。
实施例
以下实施例中所采用的测试方法如下进行。
UV固化
粘合剂膜使用IST UV固化实验室装置,采用中压汞弧光灯进行固化。UVC剂量采用EIT Power Puck来测量和记录。UVC是200至280纳米区域。二苯甲酮光敏引发剂类别在这一区域有一个吸收峰。
剥离
粘合剂以每平方米膜60克,使用Chemsultants热熔层压涂布机,浇铸到有机硅衬垫上。固化的游离膜被转移到36或50微米的PET背衬膜上。
剥离粘合力被测量为,将压敏胶带以规定的角度和速度从标准不锈钢板移去所需要的力。所需力以每25毫米宽胶带的牛顿数表示。所用设备包括标准的FINAT2公斤覆盖橡胶的辊和标准的Instron拉伸测试机。
使用以下程序:不锈钢板(来自Rocholl有限公司的Afera钢)按标准FINAT方法清洁。使用不锈钢板之前,将其沿测试板的长度用400grit的防水干湿砂纸在水龙头下进行打磨,直至水平滑地流过钢板。此后,用水冲洗并干燥,用醋酸乙酯清洁,在人工气候室中处理至少1小时。
待测试的涂层在23℃±2℃和相对湿度(RH)50%±5%下处理24小时。切下尺寸为25毫米×175毫米的测试条。
将背衬纸从每个测试条上去除,并用轻微的指压将其粘性面向下放置于干净的测试板上,然后用标准2公斤FINAT测试辊在每个方向辊压两次,速度大约每秒10毫米。将测试条应用于测试板,速度为每2分钟一个,直到第1测试件有20分钟或24小时的停留,才移去测试条。
Instron设置为十字头速度为每分钟300毫米。胶带的自由端以180°的角度对折,夹至Instron的上颌部。板的末端被夹至Instron下颌部。然后将测试条从板上剥离,剥离力用每25毫米宽胶带的牛顿数记录。
所得到的粘合剂模式失败的结果可分为:
AF.粘合失败或干净剥离。测试件从测试板上分离而没有留下任何残留物。
CF.内粘失败。粘合剂膜内粘性地裂开,并在测试件和测试板上留下残留物。
掺合试验
用于将丙烯酸类树脂与聚烯烃混合的一般方法如下。90份丙烯酸类聚合物的起始配制物与10份聚烯烃混合,该材料在烤箱中130℃下加热,使用刮板进行人工搅拌。约一小时后,移出样品,并通过视觉观察,确定它是否已混合以及它的透明性。如果样品透光,那么将它列为清澈。如果样品变白,则认为烯烃没有混合。进一步的配制物按以下表格制造。
粘度测量
粘度测量使用Brookfield DV-I粘度计在确定温度下进行。10克样品用27号转子、设定4rpm的速度来处理。
实施例1
测试聚乙烯/聚丙烯Licocene共聚物(由Clarient提供)与A204丙烯酸类树脂的在不同水平上的相容性。视觉观察和粘度数据(使用Brookfield粘度计、用27号转子在130℃测量)显示在表1中。

A 204+PP1502 10 56,750 清澈
这些结果表明,粘度不会因按重量计加入10%而改变。该实施例还表明,不同的系统混合良好。
实施例2
测试聚乙烯/醋酸乙烯共聚物(X(醋酸乙烯%)-Y(熔体流动指数),可从不同的供应商获得,例如,Arkema公司或ExxonMobilChemicals)与A204丙烯酸类树脂的相容性。视觉观察和粘度数据(使用Brookfield粘度计、用27号转子在130℃下测量)显示在表2中。

这些结果表明,不同熔体流动的EVA是相容的。

实施例5
包括各种聚乙烯共聚物与A204丙烯酸树脂的粘合剂样品被以60gsm涂布在有机硅衬垫上,然后曝露于120mJ/cm2UVC。固化膜随后被转移到36微米的PET上,剥离粘合力值在不锈钢N/25mm上测量。结果显示于表5。

该数据表明,不同的聚烯烃不会降低BASF树脂A204的剥离粘合力值,它们主要只作为填料。它们都以类似方式发挥作用。
实施例6
粘合剂配制物由A204树脂和不同的聚烯烃制成,使用Chemsultants涂布机以60gsm涂布在有机硅衬垫上,然后在90mJ/cm2UVC下使用H灯泡,采用IST UV实验室固化装置进行固化。游离膜随后被转移至50微米的PET上,在不锈钢上进行测试。结果显示于表6。

这些结果表明,聚烯烃配方可以与常规增粘剂掺合,以获得典型的剥离粘合力结果,如同不使用填料一样。
