Description

双组分无溶剂粘合剂组合物和制造其的方法
技术领域
本公开涉及无溶剂粘合剂组合物。更确切地说，本公开涉及具有经改进的粘结强度、耐化学性和热封强度的供与层压膜一起使用的双组分无溶剂粘合剂组合物和制造其的方法。
背景技术
粘合剂组合物适用于各种目的。举例来说，粘合剂组合物用于将衬底，如聚乙烯、聚丙烯、聚酯、聚酰胺、金属、纸或赛璐芬(cellophane)粘结在一起以形成复合膜，即层制品。粘合剂在不同的层压最终用途应用中的用途为通常已知的。举例来说，粘合剂可用于制造用于封装行业中，尤其用于食品封装的膜/膜和膜/箔层制品。用于层压应用中的粘合剂或“层压粘合剂”通常可分为三个类别：溶剂类、水类和无溶剂。粘合剂的性能视类别和涂覆粘合剂的应用而改变。
可以施用高达100％固体、不含有机溶剂或水性载剂的无溶剂层压粘合剂。由于在涂覆时不需要自粘合剂干燥有机溶剂或水，因此这些粘合剂可以高线速操作并在需要快速粘合剂涂覆的应用中为优选的。溶剂类和水类层压粘合剂在涂覆时会受到可有效干燥并且去除溶剂或水载剂的速率限制。出于环境、健康和安全原因，层压粘合剂优选含水或无溶剂。
在无溶剂层压粘合剂的类别内，存在诸多种类。一种特定种类包含双组分聚氨基甲酸酯类层压粘合剂。通常，双组分聚氨基甲酸酯类层压粘合剂包含包括含异氰酸酯的预聚物的第一组分和包括一种或多种多元醇的第二组分。第一组分通过异氰酸酯单体与聚醚多元醇和/或聚酯多元醇的反应获得。第二组分为聚醚多元醇和/或聚酯多元醇。每一组分可任选地包含一种或多种添加剂。两种组分以预定比率合并并涂覆于膜/箔衬底上，其随后层压于另一膜/箔衬底。
与含传统溶剂的粘合剂相比，双组分无溶剂聚氨基甲酸酯类层压粘合剂包含较弱的初始粘结，并且在可加工层制品之前产生缓慢粘结。此外，这些粘合剂尤其在酸性条件中往往会呈现相对较差耐化学性。在一些情况下，硅烷助粘剂并入于粘合剂组合物中以改进粘结强度。然而，硅烷助粘剂无法承受耐酸性，并且粘合剂组合物的粘结强度在酸处理之后会受到损害。此外，并入硅烷助粘剂的层制品需要干燥的储存环境，因为硅烷对湿气具有敏感性。
因此，期望具有经改进的粘结强度、耐化学性和热封强度的双组分无溶剂聚氨基甲酸酯类层压粘合剂组合物和制造其的方法。

适合的膜包含纸、编织和非编织物、金属箔、聚合物和金属涂布的聚合物。膜任选地具有上面用油墨印刷图像的表面；油墨可与粘合剂组合物接触。在一些实施例中，膜为聚合物膜和金属涂布的聚合物膜，更优选为聚合物膜。
