Abstract

本发明提供了一种适合超声波焊接的聚酯组合物及其制备方法，该组合物包括以下重量份的各组分：聚对苯二甲酸‑1,4‑环己烷二甲醇酯：30～50，ABS：40～60，熔体增强剂：5～10，抗氧剂0.1～1，润滑剂0.1～1。与现有技术相比，本发明所提供的该种聚酯组合物，利用熔体增强剂，提高了熔体强度。所用的熔体增强剂为通过辐照处理后带有甲基丙烯酸缩水甘油酯基团的超高密度聚乙烯树脂，提高了其与聚对苯二甲酸‑1,4‑环己烷二甲醇酯的相容性。同时通过控制组合物的玻璃化转变温度，使超声波焊接时不产生碎屑，焊接强度高，适用于超声波焊接。

Description

适合超声波焊接的聚酯组合物及其制备方法
技术领域
本发明涉及高分子材料领域，尤其是涉及一种适合超声波焊接的聚酯组合物及其制备方法。
背景技术
超声波焊接是利用高频振动波传递到两个需焊接的物体表面，在加压的情况，使两个物质表面互相摩擦而形成分子层之间的熔合。由于焊区的声阻大，因此会产生局部高温，塑料的导热性差，热量不能及时散发，导致接触面的塑料迅速熔化，加上一定压力后，使其融合一起，达到焊接的目的。两个塑料的接触面熔融状态，影响了焊接强度。
超声波焊接作为一种快速的焊接方式，广泛的应用在车灯上，特别是汽车尾灯。汽车尾灯需要将PMMA的透明制品与PC/ABS壳体焊接。PMMA和PC/ABS超声波焊接时容易出现碎屑和焊接强度低的问题。
聚对苯二甲酸-1,4-环己烷二甲醇酯树脂与PC相比，含有环乙烷二甲醇酯官能团，玻璃化转变温度低于聚碳酸酯，与PMMA更接近。LDPE是一种高分子量的树脂，可以有效提高熔体强度，但是与聚酯和ABS材料存在相容性问题。因此，现有技术中很难将LDPE与聚酯、ABS混合制备出相容性好的组合物。
发明内容
针对现有技术中的缺陷，本发明提供了一种适合超声波焊接的聚酯组合物及其制备方法。
本发明的目的是通过以下技术方案实现的：
本发明提供了一种适合超声波焊接的聚酯组合物，包括以下重量份的各组分：
聚对苯二甲酸-1,4-环己烷二甲醇酯：30～50，
ABS：40～60，
熔体增强剂：5～10，
抗氧剂0.1～1，
润滑剂0.1～1。
优选地，所述的聚对苯二甲酸-1,4-环己烷二甲醇酯中，1,4环乙烷二甲醇含量为70-90％。
优选地，所述的聚对苯二甲酸-1,4-环己烷二甲醇酯的重均分子量为25000-40000。
优选地，所述的ABS的重均分子量为120000～150000。
优选地，所述的熔体增强剂为带有甲基丙烯酸缩水甘油酯基团的超高密度聚乙烯树脂(HDPE)，其重均分子量为3000000～5000000。HDPE难以进行官能团修饰，而通过化学辐照的方法，采用钴60对其进行辐照，可使HDPE表面带有甲基丙烯酸缩水甘油酯基团，进而可进一步提高其与基材的相容性。且若HDPE的分子量过低，则无法获得很好的溶体增强效果；而分子量过高时，化学辐照后与基材的相容性也不足。
优选地，所述的熔体增强剂的制备方法包括以下步骤：
(1)制备质量分数为30％甲基丙烯酸缩水甘油酯的甲醇溶液；
(2)将超高密度聚乙烯树脂放置在钴60下空气辐照10－100kGy，取出后与步骤(1)制备的甲醇溶液混合，反应后即得所述熔体增强剂。
优选地，步骤(2)中，所述的经辐照后的超高密度聚乙烯树脂与步骤(1)制备的甲醇溶液的固液比为1g:10ml。
优选地，步骤(2)中，所述的反应的温度为60-70℃，反应时间为4-6小时。
优选地，所述的抗氧剂包括市售抗氧剂245、抗氧剂1076、抗氧剂168中的一种或几种；所述的润滑剂包括硅酮粉、季戊四醇酯、乙撑双硬酯酰胺中的一种或几种。
本发明还提供了一种适合超声波焊接的聚碳酸酯组合物的制备方法，包括以下步骤：
按比例称取各组分，将各组分混合所得的混合物通过双螺杆挤出机共混造粒，经过熔融挤出，造粒即得所述适合超声波焊接的聚酯组合物。
现有技术相比，本发明具有如下的有益效果：
本发明所提供的该种聚酯组合物，通过化学辐照方法获得与材料相容的熔体增强剂，利用熔体增强剂，提高了熔体强度，同时通过控制组合物的玻璃化转变温度，使超声波焊接时不产生碎屑，焊接强度高，适用于超声波焊接。
具体实施方式
下面结合具体实施例对本发明进行详细说明。以下实施例将有助于本领域的技术人员进一步理解本发明，但不以任何形式限制本发明。应当指出的是，对本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进。这些都属于本发明的保护范围。
以下实施例及对比例中选用的聚对苯二甲酸-1,4-环己烷二甲醇酯PCT1中1,4-环己烷二甲醇酯含量为80％，PCT 2中1,4-环己烷二甲醇酯含量为40％，ABS用高桥石化的ABS3513；PC用的是帝人的L1225L；HDPE1用的是中石化2462H；HDPE2是带有甲基丙烯酸缩水甘油酯基团的2462H；抗氧剂为Ciba公司的Irganox 1076和Irganox 168，其重量比为1：1；润滑剂为市售的季戊四醇硬脂酸。
所述HDPE2的制备方法是：
(1)制备30％甲基丙烯酸缩水甘油酯的甲醇溶液；
(2)将HDPE 2462H放置在钴60下空气辐照10－100kGy，取出后与将(1)中的溶液按1g:10ml混合，温度为60-70℃反应5小时。
