Description

一种PPS组合物及其制备方法和应用 技术领域
本发明涉及高分子材料技术领域，特别是涉及一种PPS组合物及其制备方法和应用。
背景技术
聚苯硫醚(PPS)作为一种结晶性的特种工程塑料，其具有优异的耐高温性、尺寸稳定性、耐化学、耐蠕变性能、耐湿热和自阻燃性能等优点。基于这些优点，PPS被广泛运用于汽车传动，传感部件、电控系统、电池系统、家用电器，机械工业结构件，耐磨件等领域。但是PPS的刚性结构也导致了材料的韧性较差，纯PPS原材料的缺口冲击强度仅有3KJ/m2左右，若不进行增韧改性，在大部分领域很难使用。
现阶段对PPS增韧改性主要是以加入填料或者玻纤为主。在聚苯硫醚中加入填料或者玻璃纤维，能够有效的提高材料的刚性和韧性，但是加入填料和玻纤对材料的韧性提升有限，以玻纤为例，其含量高于50％以上时，材料的增韧效果基本已经达到极限，继续增加甚至会导致材料的韧性下降。
为进一步提高材料的韧性，需要在体系中加入增韧剂。增韧剂的引入会进一步提高材料的韧性，目前在PPS中使用的增韧剂主要为苯乙烯-乙烯/丁烯-苯乙烯嵌段共聚物、乙烯-丙烯酸丁酯-甲基丙烯酸缩水甘油酯共聚物、丙烯酸酯类、乙烯-丙烯酸酯类。但是PPS材料的分子极性低，与常规的增韧剂反应活性差，导致韧性不够。目前使用较为广泛的增韧剂较多的是甲基丙烯酸缩水甘油酯(GMA)类增韧剂，通过GMA类的增韧剂环氧基团和硫化钠法PPS通过端基反应可以大大提高材料的韧性。但是GMA和PPS材料反应后，会使材料粘度增大，如果大大降低体系流动，限制了材料在薄壁注塑中的使用。
发明内容
本发明的目的在于，提供一种PPS组合物，具有韧性好、流动性好的优点。
本发明的另一目的在于，提供上述PPS组合物的制备方法和应用。
本发明是通过以下技术方案实现的：
一种PPS组合物，按重量份计，包括以下组分：
线性PPS            35-100份，
线性PPS中含有氯、碘，其中，氯的重量含量占氯与碘的总重量含量的50％-80％，计该数值为N；
GMA类增韧剂       线性PPS重量份*N*(0.1-0.3)份；
玻璃纤维          20-50份。
氯(-Cl)来源于硫化钠法线性PPS，碘(-I)来源于硫磺法线性PPS。
线性PPS中碘或氯的含量按照EN 14582-2016的标准测试(前处理方法用氧弹燃烧法，采用离子色谱仪进行测试)：分别测试得到线性PPS中氯和碘的重量含量，氯的重量含量占氯与碘的总重量含量的百分比的公式为：氯重量含量/(氯重量含量+碘重量含量)*100％。
优选的，GMA类增韧剂的含量为线性PPS重量份*N*(0.15-0.25)份。比如氯的重量含量占氯与碘的总重量含量的65％时，N数值计为0.65。
GMA类增韧剂中甲基丙烯酸缩水甘油酯基团的重量含量百分比的范围是4-10％，优选的，GMA类增韧剂中甲基丙烯酸缩水甘油酯基团的重量含量百分比的范围是5-8％。
所述的GMA类增韧剂为甲基丙烯酸缩水甘油酯共聚物型增韧剂；所述的甲基丙烯酸缩水甘油酯共聚物型增韧剂选自乙烯-丙烯酸丁酯-甲基丙烯酸缩水甘油酯共聚物、乙烯-丙烯酸甲酯-甲基丙烯酸缩水甘油酯共聚物中的一种或两种。
GMA类增韧剂可以是市售产品也可以是通过自制获得，为了详细探索GMA类增韧剂中甲基丙烯酸缩水甘油酯基团的重量含量百分比对于PPS组合物性能的影响，本发明申请实施例和对比例采用自制原料。
GMA类增韧剂的制备方法为：将乙烯-丙烯酸丁酯共聚物、乙烯-丙烯酸甲酯共聚物、或其他增韧剂(如POE)等树脂与GMA和过氧化二异丙苯(添加量为树脂与GMA总重量的0.1-0.5wt％)按比例加入到混合器中，在室温下，混合5分钟。将混合好的物料投入双螺杆挤出机的加料斗中，经双螺杆挤出机混炼塑化并挤出。双螺杆挤出机各段区间的温度为：一区175-185℃，二区180-190℃，三区190-200℃，四区205-215℃，五区205-215℃，六区195-205℃，七区180-190℃，八区175-185℃，九区170-180℃，机头205-215℃，螺杆转速380～400rpm。将通过双螺杆挤出机机头挤出的物料，采用水冷拉条造粒或水环造粒或水下造粒的方式制成颗粒，干燥即为GMA类增韧剂。
所述的线性PPS包括硫磺法线性PPS、硫化钠法线性PPS，在300℃、1.2kg条件下的按照标准ISO 1133-1-2011，熔融指数为50-200g/10min。
可以根据实际需求决定是否添加0-2份偶联剂。
可以根据实际需求决定是否添加0-2份抗氧剂。
本发明的PPS组合物的制备方法，包括以下步骤：按照配比，将硫磺法线性PPS、硫化钠法线性PPS、GMA类增韧剂混合均匀，后通过双螺杆挤出机挤出造粒，其中转速范围是250-500转/分，温度范围是280-310℃，得到PPS组合物。
本发明的所述PPS组合物的应用，用于制备车载电子零部件，比如节温器、传感器等。
本发明具有如下有益效果：
本发明采用两种类型的线性PPS树脂，其中硫化钠法PPS树脂是通过二氯苯与硫化钠反应获得，具有能够与GMA类增韧剂的GMA支链反应的端基氯(-Cl)，以提高力学性能。同时，特定含量的不含有活性基团的硫磺法线性PPS树脂能够提升PPS组合物的流动性。使得本发明申请的玻纤增强PPS组合物在玻纤极限增韧后能够进一步显著提高韧性(缺口冲击强度≥12.7kJ/m2，优选≥20kJ/m2)的同时具有良好的流动性(熔体流动速率≥38g/10min、优选≥50g/10min)。

实施例和对比例PPS组合物的制备方法：按照配比，将硫磺法线性PPS、硫化钠法线性PPS、GMA类增韧剂混合均匀，后通过双螺杆挤出机挤出造粒，其中挤出四段温度分别为290℃、285℃、280℃、280℃，螺杆转速为350rpm/min。，得到PPS组合物。

表1：实施例1-7PPS组合物各组分含量(重量份)及测试结果

由实施例3-7可知，在优选的GMA类增韧剂的添加量范围内，缺口冲击强度达到19kJ/m2以上，并且熔体流动速率也能够保持高于50g/10min。
表2：实施例8-12PPS组合物各组分含量(重量份)及测试结果

由实施例5/8-12可知，虽然GMA类增韧剂的GMA接枝率越高缺口冲击强度则越高，但是熔体流动性也下降严重。可见，优选接枝范围的GMA类增韧剂缺口冲击强度达到22kJ/m2以上，同时熔体流动速率也能够保持高于50g/10min。
表3：对比例1-7PPS组合物各组分含量(重量份)及测试结果
由对比例1可知，硫化钠法线性PPS所含的氯基与GMA类增韧剂中GMA基团进行反应从而有效提升缺口冲击强度，但是熔体流动速率也急速下降。而由对比例2可知，硫磺法线性PPS所含的碘基与GMA反应活性低，GMA类增韧剂中GMA基团不会进行反应，因此缺口冲击强度低但是熔体流动速率高。由对比例3和对比例4可知，当GMA类增韧剂的添加量过低时缺口冲击强度的，但GMA类增韧剂含量过高时熔体流动性低。
由对比例5和实施例5可知，硫化钠法线性PPS含量过高，GMA基团与氯基团反应程度过高，导致熔体流动性降低。
由对比例6与实施例5可知，硫化钠法线性PPS含量过低导致组合物中所含的氯含量过低，GMA与氯的反应程度较少，因此缺口冲击强度低。
由对比例7可知，硫化钠法非线性PPS虽然也含有氯基，但是其与GMA基团的反应活性低，因此无法实现本发明的技术效果。
表4：对比例8-9PPS组合物各组分含量(重量份)及测试结果
由对比例8/9可知，如GMA类增韧剂的GMA接枝率过低，缺口冲击强度的提升较少；反之则造成熔体流动速率下降严重。
