一种高强度、高耐热玻纤增强聚醚醚酮复合材料及制备方法
技术领域
本发明属于高性能聚合物领域，具体涉及一种高强度高耐热玻纤增强聚醚醚酮复合材料及其制备方法。
背景技术
PEEK是一种典型的热塑性高性能聚合物，具有耐高温、耐溶剂、耐老化、耐水解以及极高的比强度、比模量等特点，特别是在高温高湿的恶劣环境中仍然能保持良好的综合性能，因此，在对材料性能要求越来越高的今天，PEEK及其复合材料的重要性日益凸显。但是如今科技飞速发展，对材料的性能要求也在不断提高，尤其航空航天领域，要求重量轻的同时，还要求极高的强度和模量，很多领域要求非常高的热变形温度等，而这些都是纯PEEK树脂无法达到的，所以必须对其进行增强处理。
玻纤是传统的增强填料，对提高强度和耐热性有显著的作用，但是普通玻纤无法满足高端行业对材料的要求，为此本发明选用高强短切玻纤为增强填料，其性能接近美国的S-2玻纤和日本的T玻纤。玻纤的表面为亲水性，和树脂基的相容性不好，传统的硅烷偶联剂等虽然可以明显改善玻纤和树脂的相容性，但是其耐热等级低，在加工过程中分解严重，同时结构上和PEEK相差较大，无法起到有效的增容作用，因此我们选用耐热等级高、和PEEK相容性非常好的PES，PEI等树脂溶液来包覆玻纤，可以起到明显的界面增强作用。玻纤在树脂基体中的分散和长径比是其增强效果的关键，通常采用从第一排气口导入连续玻纤的方法向树脂基中引入玻纤，玻纤受到双螺杆强烈的剪切作用，破损较大，对材料最终性能有严重影响，本发明采用短切玻纤，从接近机头的第二侧喂料口加入，玻纤受到的剪切作用较小，可以保持完整，从而具有更高的长径比，更好的增强效果。
PEEK熔体黏度较大，加入玻纤后加工性变差，为此本发明加入了耐高温润滑剂，可以有效的降低熔体黏度，提高玻纤的分散性，并减少玻纤外露的情况，使产品性能更好，外观更美观。
发明内容
本发明的目的是通过失重式喂料和侧向喂料技术加入短切纤维来制备一种具有高强度和高耐热性的聚醚醚酮复合材料。
本发明制备的复合材料具有良好的力学性能、耐热性以及相对较低的成本。
本发明的高强度高耐热聚醚醚酮复合材料，其特征在于：各组分和按100wt％计算，含65-90wt％熔融指数为12-80g/10min的聚醚醚酮树脂，0-5wt％的耐高温偶联剂，10-30wt％的玻璃纤维。
聚醚醚酮(PEEK)的对数比浓粘度为0.76-0.80，熔融指数为12g/10min、21g/10min和80g/10min其结构式如(I)所示，n为≥1的整数，表示聚合度。
耐高温润滑剂为高分子量聚硅氧烷和蒙旦蜡。在树脂基复合材料的制备过程中，通常使用偶联剂来增加基体和填料之间的相容性。偶联剂可以在增强材料与树脂基体之间形成一个界面层，有效的传递应力，从而提高复合材料的性能。而常用的市售偶联剂难以承受聚醚醚酮高达360℃的加工温度，并且结构也与聚醚醚酮差异较大，因此难以应用在聚醚醚酮行业。为此，我们选用了和PEEK相容性好的几种耐高温树脂来包覆改性短切玻纤。
本发明所述的聚醚醚酮复合材料制备步骤为：
(1)将短切玻纤加入反应釜中，加入不同种类的耐高温树脂溶液一种或几种，在100℃条件下搅拌一小时，抽滤，100℃烘干8h。
(2)将PEEK，耐高温润滑剂和短切玻纤分别加入第一、第二、第三失重秤，从主喂料口加入PEEK和耐高温润滑剂，从第二侧喂料口加入玻纤，通过失重秤精确调节配方中各组分含量，加工温度320℃～380℃。
(3)将挤出的料条经传送带传输、空气冷却、切粒即得到本发明所述的高强度高耐热玻纤增强聚醚醚酮复合材料。
具体实施方式
下面结合具体实施例对本发明作进一步详细说明，但本发明并不局限于以下实施例。
实施例1：
设定双螺杆挤出机各工艺段温度为320℃、340℃、355℃、355℃、355℃、355℃、355℃、355℃、350℃、340℃，温度达到设定值后，首先开启第一失重秤，以20Kg/h的喂料速度从主喂料口加入PEEK粉料，其中PEEK熔指为21g/10min，待机头挤出PEEK后，开启第二失重秤，以0.45Kg/h的速度从主喂料口加入耐高温润滑剂，待挤出机运行平稳后，开启侧喂料螺杆和第三失重秤，以2.27Kg/h的速度加入短切玻纤，控制主螺杆转速为300～500Rad/min，扭矩不超过80％，机头熔体温度不超过400℃，得到PEEK含量88％，耐高温润滑剂含量2％，玻纤含量10％的复合材料。调整喂料参数，得到不同的配方，配方见表1，各配方性能见表2.
各实施例物理性能均按ISO国际标准进行测试，具体检测标准如下：
Figure BSA00000629224500031
表1不同配方各组分含量
Figure BSA00000629224500032
表2不同配方性能比较
Figure BSA00000629224500041
由表中可以看出，高强玻纤的加入可以显著提高PEEK的强度和耐热性，并且随着玻纤含量的增加，材料的强度和耐热性都在提高，润滑剂含量的增加，可以改善材料的加工性能，提高玻纤的分散性，从而使材料性能有所提高。
