Description

压敏粘合剂和粘合带
技术领域
本发明涉及一种压敏粘合剂。另外,本发明涉及一种包含含有压敏粘合剂的粘合剂层的粘合带;和一种结构体。
背景技术
聚甲基丙烯酸甲酯(PMMA)频繁地用作为汽车外饰件和例如附加到汽车门上部的遮阳帘(侧窗遮阳帘和门遮阳帘)的材料。在使用粘合剂接合该材料时,常常在材料的表面涂覆以底漆作为预处理剂,因为单使用粘合剂不能获得足够的粘附力。
但通常底漆含有挥发性有机溶剂,并且因为这个而存在因施加底漆时及施加后溶剂的挥发所致的施加作业环境恶化以及已向其施加底漆的材料待用于的区域(即,汽车或房间内等)的环境恶化的问题。此外,还存在施加底漆需要设定数量的劳动时间、工人改变施加和忘记施加以及所施加表面的外观因底漆污染而改变的问题。
使用丙烯酸类聚合物的压敏粘合剂已知是对各种表面具有优异的粘合性质并具有优良的耐磨性的压敏粘合剂,所述丙烯酸类聚合物包含含有丙烯酸类单体、N·N-二取代(甲基)丙烯酰胺和酸性基团的单体及可与之共聚的另一单体,如例如日本未经审查的专利申请公开H06-166857中所示。
此外,使用丙烯酸类聚合物的压敏粘合剂已知是具有优良的持粘性及优良的高温粘附性质的压敏粘合剂,所述丙烯酸类聚合物包含含有丙烯酸类单体、N-乙烯基环酰胺和酸性基团的单体及可与之共聚的另一单体,如例如日本未经审查的专利申请公开H06-166858中所示。
发明内容
不存在在宽范围的温度下对PMMA的表面具有足够粘合力的压敏粘合剂,因此,需要这样的压敏粘合剂和粘合带。
在一个方面,本发明提供了一种在包括环境温度、低温和高温的宽范围的温度下对为用于遮阳帘(一种汽车外饰件)的材料的PMMA的表面具有足够粘合力的压敏粘合剂以及具有包含所述压敏粘合剂的粘合剂层的粘合带。
在另一方面,本发明提供了一种压敏粘合剂,其包含通过聚合100质量份的单体混合物获得的聚合物,所述单体混合物含有:单体组分(1):46-60质量份的丙烯酸酯混合物,所述丙烯酸酯混合物选自碳数为4-6的脂肪族(甲基)丙烯酸烷基酯和碳数为7-12的脂肪族(甲基)丙烯酸烷基酯;单体组分(2):22-36质量份的含酰胺基团的乙烯基单体;单体组分(3):10-30质量份的非叔芳香醇与(甲基)丙烯酸的酯或是非叔脂环醇与(甲基)丙烯酸的酯;和单体组分(4):0-3质量份的(甲基)丙烯酸。
在又一方面,本发明提供了一种粘合带,其包含基础材料层和包含所述压敏粘合剂的粘合剂层。
在另一方面,本发明提供了一种结构体,其包含基础材料层、包含所述压敏粘合剂的粘合剂层以及聚甲基丙烯酸甲酯汽车外饰件。
具体实施方式
本文公开的压敏粘合剂提供在包括环境温度、低温和高温的宽范围的温度下对PMMA的表面具有足够粘合力的制品;具有包含所述压敏粘合剂的粘合剂层的粘合带;和其中所述粘合带固定到汽车外饰件上的结构体。
本发明的压敏粘合剂包含通过聚合100质量份的单体混合物获得的聚合物,所述单体混合物含有:选自碳数为4-6的脂肪族(甲基)丙烯酸烷基酯和碳数为7-12的脂肪族(甲基)丙烯酸烷基酯的丙烯酸酯混合物(单体组分(1));含酰胺基团的乙烯基单体(单体组分(2));非叔芳香醇与(甲基)丙烯酸的酯或非叔脂环醇与(甲基)丙烯酸的酯(单体组分(3));和(甲基)丙烯酸(单体组分(4))。
在本说明书中,“(甲基)丙烯酰”指“丙烯酰”或“甲基丙烯酰”。
单体
