Description

一种驻极母粒及其制备方法和应用
技术领域
本发明属于驻极母粒技术领域，尤其涉及一种驻极母粒及其制备方法和应用。
背景技术
普通熔喷聚丙烯材料静电保持时间较短，抗老化性能较差，通过往熔喷聚丙烯材料中添加驻极体材料以便保持长久的静电吸附效果是目前行业内的主要做法之一。
使用水流摩擦熔喷布使其带电，从而具备静电吸附能力，可以过滤掉空气中的颗粒物及病毒，目前已大量应用于呼吸防护及过滤材料中。通过添加无机粉体或松香类、蜡类物质，可以提升驻极效果，但是目前采用这些现有技术得到的聚丙烯驻极材料在高温高湿环境下会出现明显的电荷衰减，导致驻极耐久性较差，从而降低过滤效率。
发明内容
有鉴于此，本发明的目的在于提供一种驻极母粒及其制备方法和应用，该驻极母粒与熔喷料共熔喷制得的熔喷布高滤效低气阻。
本发明提供了一种驻极母粒，以重量份数计，包括以下组分：

本发明提供的驻极母粒是一款可适用于水驻极生产工艺的耐高温高湿的助剂，其具备良好的电荷保持能力，可满足不同环境情况，经受高温高湿环境后，过滤效率无明显衰减。本发明通过各组分之间的配合得到的聚丙烯驻极母粒，具有高流动性，且其挥发分和熔融指数更稳定，能够适应水驻极加工工艺，有效提升驻极母粒生产出的聚丙烯熔喷无纺布的驻极效果，且驻极效果稳定，提高过滤效率，具备低过滤阻力。
在本发明中，所述驻极剂中受阻胺类共聚物选自聚{[6-[(1,1,3,3-四甲基丁基)氨基]]-1,3,5-三嗪-2,4-[(2,2,6,6,-四甲基-哌啶基)亚氨基]-1,6-己二撑[(2,2,6,6-四甲基-4-哌啶基)亚氨基]}(驻极剂944)；
驻极剂中三嗪类共聚物选自N,N-双(2,2,6,6-四甲基-4-哌啶基)-1,6-己二胺与2,4,6-三氯-1,3,5-三嗪和N-丁基-1-丁胺和N-丁基-2,2,6,6-四甲基-4-哌啶胺的反应产物的聚合物(驻极剂2020)；
驻极剂中氟类化合物选自PTFE微粉。
具体实施例中，驻极剂选自质量比5：1的2020和944的复配物；或质量比11：20的2020和944的复配物；或质量比1：1的2020和944的复配物；或质量比10：3的944和PTFE的复配物；或2020。
在本发明中，所述驻极剂的用量优选为20～35份；具体实施例中，驻极剂的用量为31份、40份、24份、21份、13份或5份。
在本发明中，所述聚丙烯树脂在230℃、负荷2.16Kg条件下的熔体流动速率不低于600g/10min。具体实施例中，所述聚丙烯树脂的流动速率为600g/10min、或800g/10min、或900g/10min、或1000g/10min。
在本发明中，所述抗静电剂选自酰胺类和/或硬脂酰胺类；
所述润滑剂选自硬脂酸锌。
在本发明中，所述抗热氧老化剂选自受阻胺类抗氧剂和/或亚磷酸酯类抗氧剂。
在本发明中，所述抗热氧老化剂为型号1010和型号168抗氧剂的复配物；具体实施例中，型号1010和型号168抗氧剂的复配物中型号1010抗氧剂与型号168抗氧剂的质量比为1:1。
本发明提供了一种上述技术方案所述驻极母粒的制备方法，包括以下步骤：
将聚丙烯树脂55～95份，驻极剂5～40份，抗静电剂1～10份和抗热氧老化剂0.25～1.0份混合均匀后，挤出造粒，得到驻极母粒。
本发明提供了一种熔喷布，包括2～4重量份的驻极母粒和100重量份的熔喷料；

所制备的驻极母粒与熔喷聚丙烯树脂混合生产的熔喷无纺布具有静电吸附效果持久、抗热衰减性能优良、不堵塞喷丝孔等优点。且由于有机驻极剂与聚丙烯基材相容性良好，它的加入并不会破坏熔喷过程中聚丙烯的纤维结构，纤网结构保持较好，因此所制得的无纺布空气阻力小，透气性能优良。本发明提供的长效熔喷聚丙烯驻极母粒可被广泛的运用到医疗防疫产品及空气过滤产品当中。
本发明提供了一种驻极母粒，以重量份数计，包括以下组分：聚丙烯树脂55～95份，驻极剂5～40份，抗静电剂1～10份，润滑剂1.5～3份和抗热氧老化剂0.25～1.0份；所述驻极剂选自三嗪类共聚物、受阻胺类共聚物和三嗪类共聚物的复配物；或受阻胺类共聚物和氟类化合物的复配物。本发明通过采用上述种类的共聚物作为驻极剂，制得的驻极母粒与熔喷料共熔喷制得的熔喷布具有高滤效低气租性能。实验结果表明：熔喷布的滤效高达99％，气阻最低为101(Pa)。
