Description
技术领域
本公开涉及压敏粘着剂组合物。更特定而言,本公开涉及具有改进的耐水增白性的水基压敏粘着剂组合物及其制备方法。
背景技术
粘着剂组合物适用于多种目的。粘着剂组合物的一个尤其适用的子集为水基压敏粘着剂。水基压敏粘着剂在不同最终用途应用中的用途一般为已知的。举例来说,水基压敏粘着剂可与标签纸、记事本、胶带、贴花、绷带、装饰性及保护性片材及多种其它产品一起使用。
如所属领域中所用,术语“压敏粘着剂”指代包括一或多种聚合物组合物(其在干燥时在室温下强力地且永久性地保持粘性)的材料。此外,术语“水基”指示压敏粘着剂通过水性载剂制造。典型的水基压敏粘着剂将在仅接触时牢固地粘着于各种不同表面而不需要手指或手部施加压力以外的压力。
通过压敏粘着剂工业(尤其暴露于湿气的那些)辨识的一个压敏粘着剂特性为耐水增白性。改进压敏粘着剂的耐水增白性的尝试(例如通过使用可聚合表面活性剂替代传统表面活性剂)在商业上尚不理想。这是因为可聚合表面活性剂与传统表面活性剂相比相对更昂贵,且不可广泛获得。当粘着剂待用于需要良好的光学件(例如,透明膜标签)的应用中时,水基压敏粘着剂的水增白特性尤其重要。
因此,需要具有改进的耐水增白性及良好粘着力及内聚力的水基压敏粘着剂组合物以及其制备方法。
发明内容

共轭酸可包括脂肪族酸。此外,共轭酸可包括脂肪族羧酸,例如包括至少三个共轭碳-碳双键的脂肪族羧酸。再者,共轭酸可衍生自天然存在的无水油,例如桐油。更进一步,组合物可进一步包含任选地存在的一或多种增稠剂、任选地存在的一或多种消泡剂、任选地存在的一或多种湿润剂、任选地存在的一或多种机械稳定剂、任选地存在的一或多种颜料、任选地存在的一或多种填充剂、任选地存在的一或多种冻融剂、任选地存在的一或多种中和剂、任选地存在的一或多种塑化剂、任选地存在的一或多种增粘剂、任选地存在的一或多种助粘剂及其组合。
还公开用于制备组合物的方法。所述方法包括将至少一种不饱和单体及任选地存在的至少一种表面活性剂分散于水性介质中以形成乳化混合物。所述方法进一步包括将至少一种引发剂引入到乳化混合物,借此使至少一种不饱和单体聚合,且在至少一种不饱和单体聚合期间将至少一种选自由以下组成的组的化合物引入到乳化混合物:至少一种共轭酸、共轭酸的至少一种酯及其混合物,借此形成包括至少一种不饱和单体及所述化合物的互聚物。
通过至少一种表面活性剂使互聚物在乳化混合物中稳定。此外,当不饱和单体引入到水性介质时,将至少一种选自由以下组成的组的化合物引入到乳化混合物:至少一种共轭酸、共轭酸的至少一种酯及其混合物。在一些实施例中,在至少50%的不饱和单体引入到水性介质之后、或至少70%的不饱和单体引入到水性介质之后或至少90%的不饱和单体引入到水性介质之后,将所述化合物引入到水性介质。当单体乳液进料到水性介质时,所述化合物可在任何时间引入到水性介质。
还公开包括根据上文的方法制备的组合物的水基压敏粘着剂。

本公开的实例
现将通过论述说明性实例及比较实例进一步详细解释本公开。然而,本公开的范围当然不限于这些说明性实例。
乳液聚合程序
一般来说,根据本公开的乳液混合物如下制备。配备有冷凝器、机械搅拌器、温度受控热电耦及引发剂及单体的入口的4升5颈反应器进料有675g的去离子(“DI”)水且在轻微N2流动下加热到88℃。在单独容器中,单体乳液(“ME”)通过混合以下制备:275g的DI水、10g的十二烷基苯磺酸钠表面活性剂(例如来自比利时布鲁塞尔(Brussels,Belgium)Solvay S.A.的RHODACALTM DS-4(“DS-4”))、11.9g的脂肪醇醚硫酸酯表面活性剂(例如来自德国路德维希港(Ludwigshafen,Germany)BASF SE的DISPONILTM FES77表面活性剂(“FES-77”))、2.5g的Na2CO3及1,672g的包括丙烯酸2-乙基己酯(“2-EHA”)、丙烯酸丁酯(“BA”)、丙烯酸乙酯(“EA”)、甲基丙烯酸甲酯(“MMA”)及丙烯酸(“AA”)的单体混合物。
随后,将Na2CO3与过硫酸铵(“APS”)的混合物于40g DI水中的溶液添加到反应器中。紧接在添加Na2CO3及APS的溶液之后,将单体乳液进料到反应器中。进料进行80分钟。为获得所公开的组合物,将包括桐酸、桐酸与甘油的单官能酯、桐酸与甘油的二官能酯的桐酸混合物(“T-160”),或桐油(两者均可购自中国安徽省瑞芬得油脂深加工有限公司(AnhuiRefined Oil and Fatty Co.,Ltd))添加到单体中
在完成单体乳液添加时,将反应混合物冷却到60℃,随后通过两个独立管道历经30分钟逐渐添加叔丁基氢过氧化物(70%)(“t-BHP”)(9.2g于32g DI水中)的溶液及于34.5g DI水中的6.8g还原剂,例如来自美国宾夕法尼亚州查兹佛德伯格曼化学公司(Brüggemann Chemical US Company,Chadds Ford,Pennsylvania)的BRUGGOLITETM FF6 M(“FF6”)。在完成进料时,将反应物冷却到室温。所获得的组合物随后通过325目滤布过滤,以制备用于后续评估工作的组合物。
压敏粘着剂调配物
除非另外规定,否则所有样品均通过湿润剂轻微调配,例如基于总乳液,0.5%(湿润/湿润)获自新泽西州伍德兰帕氰特公司(Cytec,Woodland Park,New Jersey)的AEROSOLTM GPG湿润剂(“GPG”),以改进浸透以供实验室消耗。粘度随后使用增稠剂(例如来自密歇根州米德兰陶氏化学公司的ACRYSOLTM RM-2020(“RM-2020”))调节到约600cp(Brookfield,RVDV,30rpm,63#),且最终pH使用氨调节到7.0到7.5。
实验室消耗
聚乙烯(“PE”)膜在层压之前通过电晕处理预处理。调配的粘着剂以干物质重量计以18g/m2的量涂布到离型衬垫且在80℃下干燥6分钟。PE膜通过压敏粘着剂涂布的离型衬垫以一定方式层压,使得粘着剂层与PE膜的电晕处理侧接触,以得到粘着剂层制品。
耐水增白性测试
性能测试在粘着剂层制品在受控环境(22-24℃,50-60%相对湿度)测试实验室中调节至少隔夜之后进行。
从制备的层制品去除衬垫之后,在室温下将粘着剂涂布的PE膜浸入于水中3小时。随后,在BYK Haze Gard Plus测量设备上评估粘着剂涂布的PE膜的透明度及浑浊度特性。透明度及浑浊度根据ASTM方法D1003测量。较高透明度指示较佳耐水增白性,同时较低浑浊度指示较佳耐水增白性。
方法允许在工艺内添加及不添加桐油或桐酸而制备的样品之间的比较。在各情况下,发现添加桐酸或桐油显著改进耐水增白性性能。

d贯穿单体乳液进料添加
性能结果
在如上文所论述的BYK Haze Gard Plus测量设备上测试的实例的性能结果概述于表2中。表2中详述的浑浊度及透明度值表示浑浊度%及透明度%。
表2:IE及CE的性能结果
样品 | 浑浊度(%) | 透明度(%) |
CE1 | 55 | 86 |
CE2 | 55 | 85 |
IE1 | 40 | 89 |
IE2 | 46 | 86 |
IE3 | 38 | 89 |
IE4 | 34 | 90 |
IE5 | 47 | 87 |
IE6 | 34 | 88 |
IE7 | 48 | 83 |
如表2中所指示,出人意料地发现在IE中在聚合期间使用共轭酸或共轭酸的酯(例如桐油及/或桐酸)改进粘着剂组合物的耐水增白性。特定而言,不含有桐油或桐酸的CE1呈现实例的最高浑浊度及实例的低透明度。含有在其余组分掺合之后添加的桐油的CE2呈现实例的最高浑浊度及次最低透明度。IE1-IE7分别与CE1或CE2相比呈现显著较低浑浊度。另外,IE1及IE3-IE6分别与CE1或CE2相比呈现较高透明度。而IE2及IE7仅类似于CE1的透明度,其与CE1相比呈现显著较低浑浊度。
根据实例的比较表明根据本公开制备的用于压敏粘着剂应用的组合物与现有组合物相比呈现增加的耐水增白性。基于上文的比较,可看出这个有利特征可归因于在乳液聚合期间包含至少一种选自由以下组成的组的化合物:共轭酸、共轭酸的酯或其混合物,尤其当衍生自桐油时。
