Abstract

胶带,其粘合层包括(a)丙烯腈和(b)丁二烯和/或异戊二烯的共聚物。虽然这样的共聚物粘合层通常基本上是不发粘的,但它在适当的压力下与许多基片形成的粘合比该基片还牢固。当加热、加压时,粘结更迅速的变得牢固。引发粘合后在长时间有效期内胶带通常是能改变位置的。

Description

本发明涉及涂有粘合剂的片材,该片材通常制成宽幅,卷成大卷,有时称之为“庞然大物”。为了商业上贮存运输,这种片材可以裁成窄幅卷成筒。本发明还涉及以片状形式制出的胶带。本发明的胶带粘合层通常基本上是不发粘的,然而在中等程度的压力下会产生出人意外、高强度的粘合,这种强度甚至超过被粘材料的强度。该新型胶带按预定的用途使用之后,其底层既可以取下也可以与粘合层永久地保留。
通常采用加热加压法由粘附层密封凸泡包装,但是,必须保持压力等待粘附层受热形成粘合,因而要求设备在可行的情况下(当粘合形成较快时)慢速运转。必须极精确地调节受热压板,因而所需要的设备不仅在制造上而且在操作上都很昂贵,每类凸泡包装需要独特的或整套压板。
目前一直采用压敏胶来密封凸泡,但引起一些影响其使用的问题。例如,它的粘性要求它只能涂敷在凸泡的凸缘和嵌有凸泡的硬纸板或其它材料的接触面之间,这是难以控制的,稍未对准就会使里面的东西接触粘的粘合剂或使凸泡意外地张开。
密封凸泡包装经常要加热到175℃,这会损伤封装在里面的物品,虽然损伤不明显。例如,药丸,也就是胶囊或片剂经常被药师一个一个地封装在药物卡上,在药物卡上有隔开每个药丸的开孔间隔。每个小间隔被加热封住一个药丸,药师或许没有意识到加热对于特定的药物会造成有害的后果,由于这个原因,这样的设备在英国被禁用。在用这类装置的地方,需要延迟预热而且不利于安全。在气侯炎热期间,药师抱怨放出的热影响了工作环境。
采用热压,靠粘附层也能密封其它各种形式的容器。同样,由于形成粘合的延迟而降低密封设备的运转速度。
标签常靠粘附层贴到容器和其它物品上,用热压使容器和物品密封。除了前面提到的时间耽误之外,如果标签贴偏,还很难进行经济可行的改变。相反,溶剂活化的粘合剂虽然也具有同样的时间拖延,而且它凝结之快以致不能改变位置,但不是经常地使用。而压敏胶能消除上述拖延,足以使标签抗损害,但不容许未对准的标签改变位置。
溶剂活化和加热活化的粘合剂在许多重要的应用中是不实用的。例如把本身的侧面压制件粘结到汽车上,就需要用压敏胶,但要求牢固的、永久的 粘结时,常常不能经济地校正装配偏移。
某些容器用加热活化的粘合剂密封,例如,在盛饮料的罐头盖上封口的撕开接头片,上述封闭的密封速度也由于形成粘合时的延迟而降低。由于熔融材料耽误时间,热熔两个物品的设备的运转速度也同样被限制,如象驾驶执照类的文件经常保存在两层热封的塑料片之间。上述设备是昂贵的并因其高温也于安全不利。
经常称之为“丁腈橡胶”的丙烯腈与丁二烯的共聚物由B.F.Goodrich公司以商品名为“Hycar”(如Hcar1001)出售。由于它们是乳液聚合,即使厂商为去表面活性剂而进行洗涤之后,产品中仍然含有微量的表面活性剂,根据B.F.Goodich公司1981年三月出版的题为:粘合剂的原料”这本50页的小册子,当在粘合剂中使用丁腈橡胶时,应同时使用增粘剂、软化剂、树脂或其它橡胶(第5、8、9和47页)并应经常使用象异氰酸酯预聚物(第11页)这样的硫化剂(第6页)。丙烯腈与异戊二烯的共聚物也是市场上容易买到的。但是据认为,将其用于粘合剂时,也常结合使用上述的改性剂。
在美国专利4,212,912中,含有丙烯腈/丁二烯共聚物的粘合层用有机过氧化物使共聚物交联。
本发明提供一种胶带,其粘合层基本上可以不发粘,但在通常室温条件下施以中等压力,它能出人意外地粘结到许多物品上,其粘合力能比物品更强。
当加热时,虽然粘合力能较快地得到最大强度,但试验表明,在通常室温条件下一夜时间施以中等压力引发的粘合基本上达到与加热引发的粘合同样的强度。即使如此,象标签这样的物品贴到容器类的基物上,在其凝固后的一个相当长的时期,不论引发粘合是否加热,也能容易地改变标签的位置。虽然有上述能改变位置的特点,但是在室温或稍微升高温度的条件下施以中等压力,引发的粘合仍然有足够的起始强度,这种强度在高速运转的设备中没有延迟(与前面“背景技术”标题下讨论的延迟相反)。所以新塑料胶带能使人们合理地设计和制造较高速的设备,以适应封闭凸泡包装、密封容器和贴标签这类用途。
简单地说,本发明的胶带包括在第一面上涂有粘合层(如果需要,还含有填充剂)的底物,可选择(a)该面为低粘附表面,因而能够转移粘合剂,或(b)用粘合剂牢固地粘结。底物的另一面可选择作为防粘层。本发明胶带的特征在于,粘合层含有(a)10-50%的丙烯腈和(b)50-90%的丁二烯或异戊二烯中至少一种的未交联的共聚物。该共聚物的门尼粘度(ML-4,100℃)是30-95,而该粘性共聚物层的水接触角,至少应有20°,最好至少50°。否则就粘合不好。当水接触角至少是50°时,预料胶粘带能提供180°剥离值(定义如下)至少是45牛顿/分米。
由于这一事实,即制造商认为这种共聚物应与各种改性剂配合用作粘合剂,这种新型胶带的共聚物粘合层只不过在通常室温条件施加中等压力,竟会产生这样牢固的粘结是出人意外的。
共聚物中单体(a)最好至多为40%(重量),高于此值得到的共聚物粘合层是相当牢固的,因此在粘结期间加热可以使其更加合乎需要,而这会限制胶带多方面的适应性。当单体(a)在共聚物中少于20%(重量)时,共聚物粘合层对于需要高强度的粘结来说则有些软。
在新型胶带的共聚物粘合层中,所用的共聚物可被氢化。例如由日本Nippon    Zeon有限公司以“Zetpol    2010”商标出售的产品,即一种大约有37份丙烯腈和63份丁二烯(按重量计)的高度饱和的共聚物,其门尼粘度为85,水接触角为83°。
这种新型胶带的共聚物粘合层可以含有填充剂,如碳酸钙、碳黑、玻璃粉或玻璃微泡,短纤维,如玻璃或尼龙,二氧化硅、氧化镁和滑石。这样的填充剂往往即会降低被粘合层粘住的物体的粘合力也会降低粘合层偶然接触的物体的粘合力。通过控制填充剂的用量,新型胶带能在重新闭合的袋子、盒子、邮寄包中再次粘结。由于新型胶带的共聚物粘合层对聚烯烃的粘合力有限,故即使不加填加剂,在重新闭合的制品上也能使用。
虽然新型胶带的共聚物通常基本上不发粘,但粘性能通过包含在粘合层中的单体(a)和(b)的液态共聚物而产生或增强,这种液态共聚物可高达粘合层的40%(重量)。有用的丙烯腈和丁二烯的液态共聚物由Nippon    Zeon公司以“Nipol    N-30L”商标出售。
为了许多用途,新型胶带的底物具有低粘附表 面,以便使共聚物粘合层有可能转移,把两个物体粘结到一起。为了某些用途,底物可以永久被粘到共聚物粘合层而成为最终成品的一部分。例如当底物是透明的塑料膜时,它可以成为层压薄片的表层之一,该层压片用以保护象驾驶执照这样的文件。
由于这种新型胶带的粘合共聚物能牢固地粘附于聚氯乙烯、聚碳酸酯和聚苯乙烯薄膜上,这类薄膜特别适宜于做需要永久粘结低物的胶带,上述聚合物可以作为新型胶带的纸质底物的涂层。这种粘合共聚物也能牢固地粘附于象聚甲基丙烯酸甲酯这样的丙烯酸酯类上。由于粘合共聚物不能牢固地粘附于聚烯烃薄膜并只能中等程度地粘附于聚酯薄膜,上述薄膜可以先进行增加粘合力的处理,例如电晕放电。
当象聚氯乙烯这样的底物增塑时,其增塑剂可以迁移到共聚物粘合层中,这往往导致粘性和粘合的显著增加并伴随内聚力的极小降低。
这种共聚物粘合层可以涂到或转移到金属箔和纸层压片的整个表面,这就使本发明的胶带可用来制造每一丸药有一开孔间隔的药物卡。在室温下施加中等压力可以使多间隔凸泡的凸缘粘结到衬纸一箔带的共聚物粘合层上,这样就为药物提供了一种抗损害的密封。由于它基本上不发粘,这种共聚物粘合层不会牢固地粘结到药丸上,因此将箔一纸叠层片冲孔,药丸是很容易从间隔中取出的。与需要预先压制的加热板相反,药师能够容易地制造药物卡,即将本发明的一片衬箔一纸带覆盖在多间隔孔泡上面并用不加热的压辊用手把粘合共聚物封闭在泡孔上。
可以不首先将这种粘合共聚物涂敷在箔-纸底物上,这种粘合共聚物可以涂敷在结实、透明、欲形成凸泡热塑性薄膜(如聚氯乙烯薄膜)底物上,由于这种胶带的粘性共聚物是不发粘或基本上不粘的,所以带有粘合剂的热塑性薄膜在热成型期间能够直接接触加热压板。因为粘性共聚物层是透明的(除非以某种方式改性),在带有粘合剂的薄膜上形成的凸泡也是透明的。为了使胶带不加一次性使用的衬料而卷成卷筒销售,薄膜底物的另一面可以涂上薄的、透明的热塑性防粘层,该防粘层牢牢粘附于底物上,而上述的粘性层只轻轻地粘附于防粘层,当底物薄膜是聚氯乙烯时,较好的防粘层是乙烯/醋酸乙烯酯的共聚物,为了节约,最好涂得很薄,例如厚度为0.01至0.03毫米。从卷上裁下的一段或一片能热成型制成多间隔的凸泡,药师能够用它制成药卡。在间隔中放置胶囊之后,药师用箔-纸叠层片盖在泡孔上,然后用手动的不加热的滚筒使粘合共聚物密封层压片。
为了避免整个共聚物粘合层从新型胶带上转移,该共聚物粘合层可以由小间距片段的有序花纹组成,片段宽度要小于胶带的幅宽。在美国专利3,741,786中,叙述并附图说明了类似的压敏胶片。当使用一条这种带花纹的胶带时,为了把粘合剂转移到凸泡的表上,只有那些接触凸泡凸缘的共聚物粘合层的片段能被转移。

图2表示剥掉活动的卷筒纸16之后露出的一片胶带10,露出的共聚物粘合层12贴到透明、多间隔凸泡22的凸缘20上,每个泡孔有一个胶囊24,然后加压将粘合层封闭在凸泡22的凸缘,这样就制成药物卡。
在图3中,用聚乙烯薄膜做的盒30有一个盖舌32,本发明的胶带34粘贴到盖舌上。胶带34有柔韧的底物35,该底物的一面涂有基本上不发粘的共聚物粘合层36,该涂层含有上文提到的单体(a)和(b)的共聚物。涂在底物35的另一面的是有效的压敏胶层38,该层将胶带34永久地粘贴到盖舌32上,当盒30接触露出的粘性其聚合物层的表面时,它每时每刻都可以通过手指压到盖舌32上或打开或关闭。
图4表示聚苯乙烯瓶子40,上部车有螺纹的瓶子的顶面用本发明的胶带42粘结。该胶带有聚合物薄膜底物44,基本上不发粘的共聚物粘合层46永久粘附于底物上,当有螺纹的瓶盖48拧到瓶子上时,由于固定瓶盖48而施加的压力在粘性共聚物层46和瓶子40之间产生了强的粘合力。当以后取下瓶盖48时薄膜底物44能耐受分离而不破裂。

由于丙烯腈/丁二烯共聚物能有效地抗果汁香精油类,所以本发明的胶带主要用做密封果汁罐头的拉开接头和纸板箱。
图6表示三层复合胶带60,包括坚固、透明的热塑性薄膜底物62,透明共聚合物粘合层64和透明热塑性防粘层66,防粘层牢固地粘附于薄膜底物62上,但共聚物粘合层64却在防粘层上粘附不良。为了贮运方便,胶带可卷成卷筒。复合胶带60的段或片能热成型变成凸泡,其外形与图2的凸泡22一样。
水接触角
用Rame    Hart公司制造的NRL接触角测量器,按Zisman法测量在粘合层表面上固着水滴(2微升)的最大升角。该微滴至少要从六个不同的位置来观察,测量的角度精确到±2°,并记录其平均值。
180°剥离值
试验胶带有作为底物部分的复合双轴取向薄膜,其厚为0.05毫米,该膜含有0.04毫米的聚对苯二甲酸乙酯层,还有对苯二甲酸乙酯和间苯二甲酸乙酯(摩尔比80/20)共聚物的非晶相层,将试验的粘合剂涂到共聚物表面并干燥到厚度约为0.01毫米。
为了试验胶带,把一窄条未增塑的聚氯乙烯(PVC)薄膜(5×12.5厘米)用同样大的两面涂胶的压敏胶带粘在平板上,把2.5厘米长的试验窄条两次通过2公斤的硬橡胶辊,依靠重力将其粘到PVC表面,保压10分钟之后,把胶带自由端固定在Instron拉力试验机的刻度盘上,与PVC薄膜呈180°角以30厘米/分的速度从PVC上斯开。胶带的180°剥离值是剥离开始后两次测量的平均值。
在实施例中,除非另作说明,所有份数都按重量计。实施例中所使用的是下列丙烯腈和丁二烯的共聚物。(见表1)
实施例1
为了用于制造药物卡,将0.04毫米的蜡光漂白牛皮纸,0.09毫米的铝箔制成纸-箔叠层片,其中稀的酪素氯丁橡胶粘合剂把纸和箔粘结起来,而虫胶盖满露出的箔表面,在上述虫胶涂层上用刮刀涂布1份丙烯腈和丁二烯的共聚物(“Hycar    1000×88”)和4份甲乙酮的溶液,为了提供本发明的衬纸-箔胶带,涂层在干燥箱中干燥,干燥后的共聚物粘合层厚度约为0.015毫米。
将0.175毫米厚的未增塑聚氯乙烯薄膜热成型,以提供含有许多空穴的凸泡,把胶囊嵌入各个凸泡。象附图的图2中说明的那样,本实施例中一片衬纸-箔胶带的共聚物粘合层贴在凸泡的面上。在室温下用硬橡胶辊带借助于手的适当压力,粘合层就被粘到凸泡的凸缘上,于是制成了密封药物卡,纸-箔叠层片开孔后有些胶囊仍会粘到撕开的叠层片上,从上面很容易拾起胶囊,这样的粘合力可以认为是一种优点,因为这有助于防止胶囊掉到地板上,那些可能讨厌任何粘合剂的用户希望用制造例2中的药物卡来消除粘合层的弱的粘性。
实施例2
除了用下述物质的溶液涂敷粘合层外,有纸-箔底物的胶带按例1制造。
份数
95    “Hycar    1000×88共聚物
27    碳酸钙    平均粒径约1微米
2.3    邻苯二甲酸二辛酯
0.35    空心玻璃微泡,通常平均直径为20至70微米
480    丁酮
干燥的共聚物粘合层的厚度约为0.02毫米。一片胶带由其共聚物粘合层粘结于凸泡的凸缘上,就象实施例1中那样,当冲孔时,各个胶囊从各个间隔中自由地落下。
试图小心地从实施例1和实施例2中的药物卡上剥离纸-箔叠层片,结果纸-箔叠层片被撕裂和撕破,从而可以断定,对于不引人注目的人为损害,这两种药物卡是非常结实的。

将该溶液用刮刀涂布到一次性纸质底物的两面,该底物进行过硅橡胶低粘合力处理,然后烘干到厚度约为0.02毫米。为了存放和日后解卷并切成长条,本发明所得到的胶带卷成卷筒形,卷的幅宽约1厘米。
由0.175毫米厚的未增塑聚氯乙烯薄膜热成型得到外形尺寸约5厘米×10厘米的凸泡,在其侧边凸缘宽为0.63厘米。将本实施例中两条宽为1厘米的胶带沿长度方向贴在凸缘边,剥去纸质低物之后,露出的粘合共聚物面贴到印刷卡片坯料上,该坯料的面上有薄而透明的醋酸乙烯酯和氯乙烯共聚物的涂层。在室温下用手压硬橡胶辊卡片坯料贴在凸缘边。在没有脱层和撕破的情况下不能剥开卡片坯料,证明密封的凸泡基本上是抗损害的。
实施例4
把生效的压敏胶层,即95.5份丙烯酸异辛酯和4.5份丙烯酸的共聚物涂敷在两面经过电晕处理的0.025毫米双轴取向的聚对苯二甲酸乙酯(聚酯)薄膜底物的一面上。用聚乙烯薄膜覆盖压敏胶层后,用如实施例3中的丙烯腈/丁二烯粘合共聚物涂敷在聚酯薄膜的另一面,从而提供了本发明的双面胶带,将该带裁成1厘米的幅宽。
将两条双面涂丙烯腈/丁二烯粘合共聚物正面沿着长度方向贴到实施例3中凸泡的凸缘边,然后剥去聚乙烯,将压敏胶正面贴到实施例3中印刷卡片坯料上,没有乙烯基涂料的坯料除外。在没有脱层或撕破的情况下,不能成功地剥开卡片坯料,证明密封的凸泡是抗损害的。
实施例5
为了提供本发明的胶带,在127℃下,在0.25毫米未增塑的聚氯乙烯薄膜上挤出0.013毫米丙烯腈/丁二烯/异戊二烯三元共聚物(“Nipol    DN-1201    L”)的粘合共聚物层。用一次性的聚乙烯薄膜覆盖粘合共聚物层后,没有胶带卷好的供贮存。以后解卷并揭去聚乙烯薄膜之后,在230-260℃的模板温度下将一片胶带热成型(585K    Pa    6秒)以得到如图2中列举的多间隔的凸泡。凸缘和凸泡间隔内正面用共聚物粘合层粘结。将凸泡的承受粘合剂的凸缘和如实施例1中使用的纸-箔叠层片相粘结,例外的是用醋酸乙烯酯/氯乙烯共聚物涂料而不是虫胶涂料。在室温下用硬橡胶辊施加手压之后一夜时间能得到药物卡。在不脱层或撕破的情况下,不能剥开纸-箔叠层,证明它具有优良的抗损害。各个胶囊从冲孔的卡片上自由地从凸泡间隔中落下。
实施例6
在127℃下,在0.25毫米未增塑的聚氯乙烯薄膜上挤出0.013毫米的丙烯腈/丁二烯/异戊二烯三元共聚物(“Nipol    DN-1201    L”)的共聚物粘合层,在聚氯乙烯薄膜的另一面上,挤出0.05毫米乙烯和醋酸乙烯酯的共聚物层(“Elvax660”E.I.dupont    de    Nemours)以提供本发明的三层复合胶带,为了便于贮存将其卷好。在30℃时,几天以后卷筒形中的粘性共聚物层只是略微粘到乙烯/醋酸乙烯酯的共聚物层上。经评定,这种三层复合胶带虽卷筒,但在长期存放之后能够干净地解卷。
将一片这种三层复合胶带热成型以便提供多间隔凸泡并以实施例5中同样的方法与纸-箔叠层片粘结。在室温下一夜时间得到药物卡,在没有脱层或撕破的情况下,无法剥开纸-箔叠层片,各个胶囊从冲孔卡片上自由地从凸泡间隔中落下。
实施7-11
丙烯腈含量高的共聚物不加热也能很牢固地粘结,除非他们象“Nipol    N-30L”那样用液态共聚物进行了改性,丙烯腈含量较低的共聚物在室温下也会形成良好的粘结,与液态共聚物混合其粘结性更好。本发明的胶带试验见表2。
如上所述,保压10分钟之后,测到180°剥离值,在室温下保压一夜之后,试验实施例7,8,9,10,11的不同的窄条胶带,每种底物断裂。
有时能改进180°剥离值,其方法是在粘合共聚物表面简单地浇温水(30℃)然后在65℃下干燥30分钟,于是从试验胶带的表面除去表面活性剂,结果见表3。
在室温下保压一夜之后,实施例9-11的胶带经过洗涤,裁成窄条,在测定180°剥离值时,每种底物断裂。
