Description

适用于挤出涂覆的基于乙烯的聚合物组合物
本发明涉及一种适用于挤出涂覆的基于乙烯的聚合物组合物。本发明还涉及一种包含这种组合物的挤出涂覆制品以及这种组合物的用途。
聚烯烃，尤其是聚乙烯，通常用于挤出涂覆中。
挤出涂覆是将熔融的聚合物涂覆至基材材料如纸板、纸、铝箔、无纺布、塑料膜、波纹纤维板或纤维素、聚合物纤维、油布上。
在挤出涂覆过程期间，聚合物和基材由此组合，从而形成具有特定协同特性的产品。提高加工和产品要求以及质量要求可导致在挤出涂覆过程期间可发生若干不同的问题。
由此，与流变学有关的现象如网络稳定性(web stability)、缩幅(neck-in)和拉伸(draw-down)可在挤出涂覆中导致问题。
网络稳定性尤其在聚合物熔体的冷却期间可能是一个问题，因为若干竞争的力组合并使得冷却过程非常复杂。冷却可导致熔融聚合物层或熔融聚合物“网络”破裂。
缩幅可为涂层宽度的减小。其可导致基材上存在未涂覆的区域。
拉伸是聚合物熔体由其所施加在上面的基材牵引而由口模间隙厚度拉伸成涂层厚度的薄涂层(优选不破裂)的能力。
在挤出涂覆中，将熔融的聚合物薄膜涂覆至基材上。
在高挤出涂覆速度下，即使熔体中的微小扰动也可能导致主要的质量问题，这可非常快地导致大量废品。因此，要求聚合物具有高且恒定的品质以避免因聚合物网络破裂和缩幅现象而导致的废品。
此外，在高的挤出涂覆速度下，优选具有极好的拉伸性能的聚合物。
目前，通过使用高压压热器技术生产的LDPE可用于挤出涂覆应用中。使用压热器方法获得的LDPE通常适用于挤出涂覆中。
然而，对极高的挤出涂覆速度如200-275m/分钟而言，LDPE可能不再适用，因为拉伸性能可能不够好且可能出现网络破裂的现象。此外，LDPE的粘度可能非常高，这可导致高涂料重量。
因此，本发明的目的是提供一种适用于挤出涂覆的基于乙烯的聚合物组合物，其在挤出涂覆过程中，尤其是在极高的挤出涂覆速度下，可具有或允许提高的网络稳定性和/或降低的缩幅和/或改善的拉伸性能和/或降低的粘度和/或降低的涂料重量，同时还获得其它希望的性能。
本发明的目的是提供一种适用于挤出涂覆中的基于乙烯的聚合物组合物，其中解决了上述问题。
因此，本发明提供了一种用于挤出涂覆的基于乙烯的聚合物组合物，其包含如下组分或由其组成：
a)51-95重量％聚合物A，其包含基于聚合物A的重量为至少60重量％的乙烯或由其组成；和
b)5-49重量％聚合物B，其包含基于聚合物B的重量为至少60重量％的乙烯和基于聚合物B的重量为0.01-5重量％的包含至少两个(甲基)丙烯酸酯官能的化合物或由其组成；
其中a)和b)的重量百分数基于该基于乙烯的聚合物组合物的重量。
本发明的基于乙烯的聚合物组合物可尤其适于挤出涂覆，尤其是在基材如纸板、纸、铝箔、无纺布、塑料膜、波纹纤维板或纤维素上。
本发明的优点在于，本发明的组合物可用于挤出涂覆，尤其是在高和/或极高的挤出涂覆速度下，同时减少网络破裂和/或缩幅现象和/或具有良好的拉伸性能。
聚合物A可为乙烯和至少一种作为共聚单体的其它α-烯烃、尤其是例如丙烯、丁烯、己烯或辛烯的共聚物。
聚合物A可包含乙烯和至少一种作为共聚单体的α-烯烃。优选地，聚合物A可由乙烯和至少一种作为共聚单体的α-烯烃、优选正好一种作为共聚单体的α-烯烃组成。
聚合物A可包含基于聚合物A的重量为例如至少60重量％、优选至少85重量％、进一步优选至少87重量％、进一步优选至少88重量％、进一步优选至少90重量％、或者至少91重量％、或者至少95重量％的乙烯，或者由其组成。
聚合物A可具有0.01-40重量％、优选0.1-15重量％、优选1-12重量％、优选3-10重量％的共聚单体含量，基于聚合物A的重量。
聚合物A可尤其例如为线性低密度聚乙烯(LLDPE)，尤其是包含乙烯和作为共聚单体的1-己烯或1-丁烯或者由其组成的LLDPE，进一步优选具有基于LLDPE的重量为0.01-40重量％、优选0.1-15重量％、优选1-13重量％、优选3-12重量％的共聚单体含量的LLDPE。
线性低密度聚乙烯(LLDPE)可例如通过任选在一种或多种共聚单体存在下聚合作为单体的乙烯而获得。例如，该共聚单体可包括1-丁烯、1-戊烯、4-甲基-1-戊烯、1-己烯、1-庚烯和/或1-辛烯。
例如，该共聚单体可以以与低密度聚乙烯的总重量相比为≤40.0重量％、或者≤30.0重量％、或者≤15.0重量％、或者≤10.0重量％、或者≤5.0重量％、或者≤3.0重量％的量存在。
例如，该共聚单体可以以与低密度聚乙烯的总重量相比为≥0.05重量％、或者≥0.10重量％、或者≥0.30重量％、或者≥0.50重量％、或者≥1.00重量％的量存在。
