Abstract

本发明描述了一种可拉伸剥离的粘合带,所述粘合带包括背衬和涂覆在所述背衬的至少一个表面上的第一层压敏粘合剂组合物,所述粘合带具有介于0.05mm和0.10mm之间的厚度以及介于850%和2200%之间的断裂伸长率,能够牢固地粘结至基底,并且此后在以90度或更大角度从所述基底的所述表面被拉伸后能够从所述基底上移除,同时在所述粘合带从所述基底移除之前不断裂,并且不在所述基底上留下大量压敏粘合剂残留物,其中所述压敏粘合剂包含官能团封端的聚氨酯。本文还描述了一种包括本发明的可拉伸剥离的粘合带的电子设备。

Description

拉伸可靠的粘合制品及其使用和制造
技术领域
本发明涉及粘合带,更具体地涉及可拉伸剥离的粘合带。
背景技术
粘合带(例如压敏粘合带)通常牢固地粘结至基底,因为粘合带与基底的后续分离既非预期也非所期望的。但是,存在可移除的粘合带,其中粘合剂经过专门配制以便在使用后干净而便利地从基底移除。美国专利No.6,527,900公开了一种可施加至基底的可移除的粘合带。在附接到基底之后,粘合带便牢固粘结,但是可以在不损坏基底的情况下容易地移除,只需以基本平行的方向(即,小于约35度)将其拉伸至基底的表面即可。在某些情况下,如果此类粘合带用在高度紧凑的电子设备中(例如,用在移动电话中以将内部放置的电池与其凹陷的基底粘合),则无法从平行或小于35度的方向将该粘合带移除。
发明内容
因此,希望获得可拉伸剥离的粘合带,该粘合带能够牢固地粘结至基底,并且此后在以90度或更大角度从基底表面被拉伸后能够从基底上移除,同时在从基底移除粘合带之前背衬不破裂,并且不在基底上留下大量压敏粘合剂残留物。
第一方面涉及一种包括背衬的可拉伸剥离的粘合带,所述背衬具有第一表面和第二表面并且由交联的热塑性聚氨酯制成,以及设置在第一表面和第二表面中的至少一者上的压敏粘合剂。压敏粘合剂由丙烯酸共聚物形成,该丙烯酸共聚物包含官能团封端的聚氨酯。粘合带具有范围介于0.05mm和0.10mm之间的厚度以及范围介于850%和2200%之间的纵向断裂伸长率,且粘合带能够牢固粘结至基底,并且此后在以90度或更大角度从基底表面被拉伸后能够从基底上移除,同时在从基底移除粘合带之前不破裂,并且不在基底上留下大量压敏粘合剂残留物。

具体实施方式
如本文所用,术语“一个”、“一种”、“该/所述”可互换使用并意指一个或多个;“和/或”用于指示可能发生一种或两种所述的情况,例如A和/或B包括(A和B)和(A或B);“至少二”包括二和更大的所有数字(例如至少4、至少6、至少8、至少10、至少25、至少50、至少100等)。“至少一”包括一和更大的所有数字(例如,至少2、至少4、至少6、至少8、至少10、至少25、至少50、至少100等)。“交联”是指用化学键或化学基团连接两种预形成的聚合物链,以便增大材料的模量;“交联的”是指两种预形成的聚合物链使用化学键或化学基团连接,以便增大材料的模量;
“交联剂”是指交联试剂。“聚合物”、“聚合物的”和“聚合产物”是指为均聚物、共聚物、三元共聚物等的材料。“共聚物”和“共聚物的”是指由至少两种单体形成的聚合物材料。也就是说,共聚物是聚合物的仅排除了均聚物的子集。“丙烯酸酯”是指包含丙烯酸酯、甲基丙烯酸酯结构或它们的组合的化合物。当提到范围时,范围端值应理解为包括在范围中。例如,表达“在从x至y的范围中”、“在x至y的范围中”、“在从x至y的量中”、“在x至y的量中”、或类似的表达包括端值x和y。
术语“玻璃化转变温度”或“Tg”是指材料从玻璃态转变为橡胶态的温度。在此上下文中,术语“玻璃态”意指材料硬且易碎(并且因此相对容易破碎),而术语“橡胶态”意指材料是有弹性且柔性的。对聚合物材料而言,Tg是将其玻璃态与橡胶态分开的临界温度。如果聚合物材料处于低于其Tg的温度下,那么大规模的分子运动就会受到严格限制,因为该材料是基本上冻结的。另一方面,如果聚合物材料处于高于其Tg的温度下,那么分子运动以其重复单元的规模发生,从而允许材料为柔软或橡胶态的。聚合物材料的玻璃化转变温度通常使用诸如差示扫描量热法的方法确定。在本文中任何提及单体的Tg均指由单体制备的均聚物的Tg。
现在参见图1,可拉伸剥离的粘合带2包括隔离衬件4、附接至隔离衬件的第一粘合剂层6、附接至第一粘合剂层的背衬层8以及第二粘合剂层10。在某些实施方案中,第一粘合剂层和第二粘合剂层可以是相同的。在某些实施方案中,粘合带可包括隔离衬件、附接至隔离衬件的粘合剂层、附接至粘合剂层的背衬层。在各种实施方案中,粘合带可具有至少约0.05毫米(mm)、约0.07毫米、约0.09毫米或约1.0毫米的最小厚度,以及不大于1.2毫米的最大厚度。在某些实施方案中,使用ASTM D3330测试标准,粘合带的180°剥离强度为至少0.2N/mm、至少0.5N/mm、至少0.7N/mm、至少0.8N/mm,但不超过1.0N/mm。
在某些实施方案中,背衬层8由热塑性聚氨酯聚合物制成。更具体地讲,背衬层由基于聚酯的热塑性聚氨酯聚合物制成。合适的聚酯型热塑性聚氨酯包括但不限于基于芳族聚酯的热塑性聚氨酯、脂族聚酯型热塑性聚氨酯。在一些实施方案中,热塑性聚氨酯是芳族羟基封端的。在一些实施方案中,芳族羟基的重量%为介于0.3重量%和3重量%之间,而热塑性聚氨酯的软分子链的玻璃化转变温度(Tg)为介于-20℃至40℃之间,并且热塑性聚氨酯的硬分子链的玻璃化转变温度/kofler熔融温度为介于60℃至110℃之间。热塑性聚氨酯的撕裂强度高于35MPa,肖氏硬度为55A至70A,优选地为65A。

背衬层的杨氏模量为至少25MPa、至少30MPa、至少35MPa、至少45MPa并且不超过50MPa。可以例如采用ASTM D790-07或ASTM D882-02方法测定杨氏模量。背衬层可具有介于35微米和70微米之间的厚度。背衬层可以具有任何合适的构造。例如,背衬层的形式可以为具有任意合适厚度、组成和不透明度或透明度的膜。背衬层可为单层膜和/或多层膜。
粘合剂层由进一步改性的压敏粘合剂制成。在一些实施方案中,压敏粘合剂由反应混合物形成,该混合物包含以下组分:
基于反应混合物的总重量计,25重量%至90重量%的丙烯酸共聚物;
基于反应混合物的总重量计,5重量%至30重量%的官能团封端的聚氨酯聚合物;
基于反应混合物的总重量计,0重量%至45重量%的增粘剂;基于反应混合物的总重量计,0.02重量%至0.1重量%的交联剂;以及
0重量%至3重量%的颜料。

在一些实施方案中,官能团封端的聚氨酯聚合物包括脂族磺酸封端的聚氨酯、或芳族羟基封端的聚氨酯或它们的组合。官能团封端的聚氨酯的Tg为介于60和80℃之间。基于反应混合物的总重量计,官能团封端的聚氨酯的重量百分比在5重量%至30重量%之间变化、在10重量%至25重量%之间变化、在10重量%至15重量%之间变化。在一些实施方案中,官能团封端的聚氨酯聚合物包括脂族磺酸封端的聚氨酯,并且磺酸基团的重量百分比为介于2重量%和5重量%之间。

用于本发明中的交联剂包括但不限于聚异氰酸酯。基于反应混合物的总重量计,交联剂的量在0.02重量%至0.1重量%之间变化、在0.05重量%至0.09重量%之间变化、在0.06重量%至0.08重量%之间变化。交联剂的NCO(异氰酸酯基团)含量为5%至12%,并且交联剂的粘度为400至800cP。合适的交联剂包括但不限于脂族聚异氰酸酯(IPDI三聚物、HDI三聚物)。
如果需要改变粘合带的颜色,反应混合物可包含0重量%至3重量%的颜料。

表1:可拉伸剥离的粘合带的原材料
测试方法
本发明的样本的性能测试和表征按照以下测试方法进行。
剥离粘接强度测试(ASTM D 3330/D 3330M-04)
按照ASTM国际标准D3330所述,使用IMASS SP-200滑动/剥离测试仪(购自美国马萨诸塞州阿科德市的IMASS公司(IMASS,Inc.,Accord,MA),以12英寸/分钟的速度执行180度剥离强度测试。
张力测试(ASTM D 3759)
按照ASTM国际标准D3759所述,使用12.7mm×25.4mm粘合带条,以304.8mm/min的十字头速度在Instron(4465型)上执行张力测试。
张力测试(ASTM D1876)
根据ASTM国际标准D1876,使用25.4mm×150mm粘合带条和Instron(4465型),以304.8mm/min的十字头速度执行T剥离。
如图2所示,使用Instron(4465型),以12英寸/分钟的十字头速度在60mm×20mm×0.1mm(厚度)粘合带样本上测试最大粘结强度。
如图3所示,使用Instron(4465型),以12英寸/分钟的十字头速度和90度拉动角度,在90mm×20mm×0.1mm(厚度)的样本上执行拉伸剥离测试。以干净移除的样本占总测试样本的百分比记录拉伸剥离的可靠性。在65℃和95%相对湿度下老化72小时之后,在1)原始样本和2)样本上执行拉伸剥离测试。
防摔测试
如图4所示,对60mm×20mm的样本执行防摔测试。测试设备包括板14、与板连接的支承件16、测试块18和用于经由一定高度的棒支承测试块的基座20。在测试时,将带有本发明粘合带的制品从板表面掉落以测试其附着到测试块18时的防摔性。从初始高度以5cm的增量增大掉落高度,并观察失效高度(HOFF)。任何局部粘合失效/剥离都计为失效。
残留物测量
通过目视(即肉眼)测量要移除粘合剂的基底上的残留物。
剥离可靠性测试
如图3所示,使用Instron(4465型),以12英寸/分钟的十字头速度和90度拉动角度,在90mm×20mm×0.1mm(厚度)的样本上执行拉伸剥离测试。以干净移除的样本占总测试样本的百分比记录拉伸剥离的可靠性。在65℃和95%相对湿度下老化72小时之后,在1)原始样本和2)样本上执行拉伸剥离测试。
制备例
下面示出了可拉伸剥离的粘合带实施例(E1和E2)的详细配方。
表2:可拉伸剥离的粘合带和相关产品的配方
实施例E1和E2
改性的丙烯酸粘合剂层
接下来制备丙烯酸共聚物。从陶氏化学公司(Dow Chemical Co.)购得一瓶2-乙基己基丙烯酸酯(2-EHA),并准备4.5克丁基丙烯酸酯(BA)以及4.5克丙烯酸(AA,购自巴斯夫公司(BASF Corp.))。该瓶还包含177克乙酸乙酯(EtOAc,一种溶剂)和0.200克VAZO-67(购自杜邦公司(DuPont)的偶氮腈聚合引发剂)。用氮气扫吹该混合物以除去所有氧气,然后将瓶密封。将此密封瓶放入水浴中,并在58℃下加热24小时。用另外的56克EtOAc将所得样品进一步稀释。最终样品为澄清的粘稠溶液。
通过在改性丙烯酸粘合剂下混合表2中列出的组分(交联剂除外),以产生粘度为约8,000cps的可涂覆溶液,从而制备含40%固体的粘合剂溶液。然后,将粘合剂溶液与DESMODUR DN交联剂混合并使用溶剂涂布机涂覆在已涂覆有聚烯烃的牛皮纸(PCK)隔离衬件上,然后在105℃的连续加热烘箱中干燥2分钟,以产生21微米的粘合剂层。
PU层
通过先将25份基于芳族聚酯的热塑性聚氨酯(ESTANE 5702)和75份甲基乙基酮(MEK)混合,然后加入Z4470交联剂来制备聚氨酯。使用溶剂涂布机将PU溶液涂覆在PCK衬件上,然后在80℃的连续加热烘箱中干燥5分钟,以产生58微米的PU层厚度。
通过将粘合剂表层层合到PU层的两个表面制备本发明的多层粘合带,如图1所示。可以将这种粘合剂涂覆在背衬层8上来形成粘合带2,或者可以使用这种粘合剂来形成单个均匀粘合剂层形式的粘合剂制品(即没有背衬层)。可拉伸剥离的粘合带的构造包括涂覆聚烯烃的牛皮纸(PCK)隔离衬件、第一改性丙烯酸粘合剂层、特定聚氨酯芯以及第二改性丙烯酸粘合剂层,正如图1所示。第一改性丙烯酸粘合剂层和第二改性丙烯酸粘合剂层的配方可以是相同的。热熔融工艺也适用于制备拉伸剥离粘合带,方法是通过挤出机和多层共挤出模具来形成粘合剂层和芯层。
比较例(C1、C2、C3和C4)
表2中示出了比较例。对比物C1(T公司0.1mm粘结和分离DC粘合带)和C2(M公司0.9mm)为商业产品,如表2所述。使用E1和E2中所述的相同工序制备对比物C3和C4,不同之处在于粘合剂不含热塑性PU添加物,如表2所示。
表3:相关可拉伸剥离的粘合带的构造
表3示出了本发明的可拉伸剥离的粘合带与对比粘合带相比的构造。
表4:相关可拉伸剥离的粘合带的性能比较
如表4所汇总,对比物C1和C2表现出较差的剥离可靠性:对于C1为70%,对于C2为0%,因为这些是传统的可拉伸剥离的粘合带,最初为平面内拉伸剥离所设计。本发明实施例E1和E2的粘合带包含含有脂族磺酸封端聚氨酯(即SINOCHEM)和交联的芳族羟基封端的聚氨酯的改性丙烯酸粘合剂,表现出断裂伸长率>1000%以及最大应力>40MPa。比较E1和C3以及E2和C4的测试结果,结果表明,通过将表格中所列的特殊聚氨酯与丙烯酸共聚物、增粘剂和交联剂共混,可得到具有平衡的粘附力、固定力以及对于交联的聚氨酯层改善的粘附力的改性丙烯酸压敏粘合剂,从而让最终粘合带具有可靠的垂直拉伸剥离性能以及与对比物相比增强的防摔性。
图5示出了E1、C1和C2的垂直拉伸剥离性能,其中C1和C2与E1相比具有明显更低的断裂伸长率和最大应力。在65℃和95%相对湿度下湿热老化72小时后,C2表现出明显减小的断裂伸长率和张力强度,而E2则保持高断裂伸长率和张力强度。这表明由所发明的组合物制备的粘合带不仅在平衡的粘附力、垂直拉伸剥离性能和防摔性方面具有优势,而且与市面上的对比粘合带相比具有改善的湿热老化抗性。
