Description

一种耐水白丙烯酸酯压敏胶及其制备方法 技术领域
本发明涉及压敏胶粘剂的制备方法,尤其涉及一种耐水白性能良好且内聚强度优异的丙烯酸酯压敏胶粘剂。
背景技术
当前,由多种类的丙烯酸酯单体共聚而得的丙烯酸酯聚合物是很重要的一类压敏胶粘剂。近几年来,由于在包装、运输、材料等方面的快速发展,导致对标签类产品的需求量不断扩大,因而对压敏胶产品的需求量也不断扩大。丙烯酸酯类压敏胶乳液具有无毒、无污染等符合安全环保的特点,并且其耐老化性、耐候性、压敏性和粘合性也十分优异,使压敏胶产品得到了广泛应用。
经过多年发展,不断调整丙烯酸酯类压敏胶产品的聚合配方以及聚合工艺,在选取丙烯酸酯类的软单体、硬单体的同时,又引入了多种功能性单体,改善其性能。尽管如此,丙烯酸酯压敏胶乳液在粘结性能、耐高温、耐水白、耐湿性等方面不如溶剂型产品。
压敏胶乳液产品在遇水接触后会有变白现象,这是由于水分子从外部向乳液层扩散时在胶层空隙中形成水囊,产生渗透压作用于乳胶颗粒,光线照射过水囊发生光散射,引起水白现象。丙烯酸酯压敏胶乳液使用乳液聚合方法合成,过程中大多涉及的表面活性剂、引发剂、缓冲剂等都是水溶性。在乳液干燥成膜的过程中,乳液中的带电粒子和这些水溶性成分会赋予胶膜驱动力,因此当产品遇水后水分子很容易从外部与这些成分发生作用,产生对水敏感的流延膜,胶膜呈现乳白色,当水温高时,发生水白化程度更高,影响外观和粘合性能。对于需要在低温潮湿条件下保存的产品,如饮料瓶等透明食品包装,在低温储存后放置室温的过程中,空气中水分遇瓶身液化附着在瓶壁上接触胶膜,导致水白问题。
压敏胶的水白问题是近几年被广泛关注的水性压敏胶的一个问题之一,也有相当多的技术人员对这个性能进行过研究。美国专利US20060263600A1对乳化体系进行过改良,选用过脂肪醇聚醚和磺基丁二酸二辛基钠盐来降低水白问题,有一定的耐水白效果但由于脂肪醇聚醚的特性使得乳化过程变得有些困难。美国专利US20050176876A1使用核壳法进行乳液聚合,并引入含氟单体来解决其耐水白性能的问题,但同样存在力学性能降低的问题。因此,同时解决耐水白性与粘合性能的问题目前依然是业界存在的技术性问题之一。

具体实施方式
下面结合实施例对本发明做更详细的描述说明。对本发明实施例中的技术方案进行清楚的描述,显然描述的实施例仅仅是本发明的一部分实施例,而不是全部的实施例,基于本发明中的实施例,本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。

作为优选,所述乳化剂选自十二烷基苯磺酸钠、十二烷基硫酸钠、改性的脂肪醇聚醚、磺基琥珀酸二辛酯钠中的两者。
本发明中,所述引发剂为自由基型引发剂,具体为过硫酸钾或者过硫酸钠。
本发明第二方面提供所述压敏胶的制备过程如下:
将表面活性剂、硬单体、软单体以及功能性单体按配方比例添加,搅拌至乳化,制得预乳液,取10-20%预乳液作为种子,待反应釜升温至81℃(其间通入氮气排气)将种子加入,取30-40%引发剂加入反应釜,关闭氮气,待温升至峰值,匀速同时滴加剩余预乳液和引发剂,反应时间4-5h,反应温度85-87℃。反应完毕后,维持反应温度保温90mins,随后进行后处理,后处理温度87℃,滴加时间45mins,保温15mins,降至室温。通过添加氨水调节乳液pH至6-8范围,加入交联剂以及润湿剂等。随后涂膜测试其耐水白、初粘力以及剥离强度。
本发明所涉及的测试方法:
