Description

一种纤维增强ABS/PBT合金及其制备方法
[技术领域]
本发明涉及高分子材料领域,尤其涉及一种纤维增强ABS/PBT合金及其制备方法。
[背景技术]
PBT(聚对苯二甲酸丁二醇酯)树脂是五大通用工程塑料之一,在汽车上的应用越来越多。目前,虽然市场上PBT合金比较多,玻璃纤维增强的ABS/PBT合金也比较多,但是现有的玻璃纤维增强ABS/PBT合金的机械性能普遍不够高,难以满足生产汽车配件的需要。
[发明内容]
本发明要解决的技术问题是提供一种具有综合机械性能较好的纤维增强ABS/PBT合金及其制备方法。
为了解决上述技术问题,本发明采用的技术方案是,一种纤维增强ABS/PBT合金,按重量百分比由以下组分组成:
Figure BDA0000448429810000011
以上所述的纤维增强ABS/PBT合金,ABS的熔融指数为25-27g/10min(220℃/10kg10kg),玻璃化温度为105-110℃。
以上所述的纤维增强ABS/PBT合金,PBT熔融指数为57-62g/10min(250℃/2.16kg),熔点为223-225℃。
以上所述的纤维增强ABS/PBT合金,相容剂为ABS接枝马来酸酐,接枝率为0.8%。
以上所述的纤维增强ABS/PBT合金,抗氧剂为N,N'-双-(3-(3,5-二叔丁基-4-羟基苯基)丙酰基)己二胺。
上述纤维增强ABS/PBT合金的制备方法,包括以下步骤:
1)按上述的重量百分比称取原料;
2)将PBT、ABS、相容剂、增韧剂、抗氧剂和润滑剂在混合器中混合3-7分钟;
3)将步骤2)中混好的原料和碳纤维置于双螺杆挤出机中掺混,经过熔融挤出,造粒。生产工艺条件为:双螺杆挤出机一区温度为200-250℃,二区温度为200-250℃,三区温度为200-250℃,四区温度为200-250℃,混合料在螺杆中输送时间为1-2分钟。
本发明通过使用碳纤维增强,有效地提高了纤维增强ABS/PBT合金材料的综合机械强度;本发明的制备过程简单,生产工艺容易控制。
[具体实施方式]
下面通过实施例对本发明进行进一步阐述:
本发明提供的纤维增强ABS/PBT合金,其组成按重量百分比为:PBT30-60%;ABS10-25%;相容剂-ABS接枝马来酸酐1-5%;增韧剂-MBS1-5%;抗氧剂0.1-1%;润滑剂0.1-1%;碳纤维10-30%。
其中,PBT为康辉石化的KH2083,其熔融指数为57-62g/10min(测试条件250℃/2.16kg),熔点为223-225℃;ABS为LG121H,其熔融指数为25-27g/10min(测试条件220℃/10kg10kg)、玻璃化温度为105-110℃。
相容剂为ABS接枝马来酸酐(接枝率0.8%),自制ABS接枝马来酸酐的制备方法为:将如下重量百分比的各组分混合,用双螺杆挤出机在温度为140-200℃的条件下挤出:
Figure BDA0000448429810000031
抗氧剂为N,N'-双-(3-(3,5-二叔丁基-4-羟基苯基)丙酰基)己二胺;润滑剂为脂肪酸酰胺。碳纤维为台湾台丽的T36S-12K。
因为PBT和ABS的相容性不是很好,但是在本发明中使用了ABS接枝马来酸酐作为相容剂使得其合金的相容性非常的好,这样不仅使得合金具有非常优良的机械性能而且也保证了材料的高光外观。
本发明纤维增强ABS/PBT合金的制备过程如下:
(1)按照重量百分比称取1中所述原料;
(2)将PBT、ABS、相容剂、增韧剂、抗氧剂和润滑剂在中速混合器中混合3-7分钟;
(3)将(2)混好的原料和碳纤维投置于双螺杆挤出机中掺混,经过熔融挤出,造粒。生产工艺条件为:双螺杆挤出机一区温度为200-250℃,二区温度为200-250℃,三区温度为200-250℃,四区温度为200-250℃,混合料在螺杆中输送时间为1-2分钟。
下面结合具体实施例对本发明作详细的描述:

其中各区段温度为:一区200℃,二区220℃,三区240℃,四区240℃,五区230℃,停留时间为90秒钟。
性能测试:
将上述3个实施例完成造粒的粒子在80-100℃的鼓风烘箱中干燥4-6小时,再将干燥的粒子在80T注塑机上注塑制样,制样过程中保持模温在70-100℃之间。
拉伸强度按GB/T1040标准进行检验,试样类型为I型,样条尺寸(mm):170(长)×(20±0.2)(端部宽度)×(4±0.2)(厚度),拉伸速度为50mm/min;
弯曲强度和弯曲模量按GB9341/T标准进行检验。试样类型为试样尺寸(mm):(80±2)×(10±0.2)×(4±0.2),弯曲速度为20mm/min;
缺口冲击强度按GB/T1043标准进行检验,试样类型为I型,试样尺寸(mm):(80±2)×(10±0.2)×(4±0.2);缺口类型为A类,缺口剩余厚度为3.2mm;
实施例1-3的配方及性能见表1和表2。
表1:
组分(重量百分比) 实施例1 实施例2 实施例3
PBT 60 54 48
ABS 23.6 19.6 15.6
相容剂 3 3 3
增韧剂 3 3 3
抗氧剂 0.2 0.2 0.2
润滑剂 0.2 0.2 0.2
碳纤维 10 20 30
表2:
性能 实施例1 实施例2 实施例3
缺口冲击强度(J/M) 100 120 160
拉伸强度(MPa) 112 134 179

弯曲强度(MPa) 162 187 231
弯曲模量(MPa) 10201 13205 17892
通过对上述数据分析后得知,碳纤维增强PBT/ABS合金材料随着碳纤维的含量不断提高,合金的机械性能也随之提高,特别是冲击强度以及弯曲模量,相对于玻纤增强的弯曲模量比较的话,性能差不多提高了一倍,因此,碳纤维增强对于弯曲模量的提升是非常有效的。主要是因为碳纤维本色固有的模量也是非常高,经过与高分子共混后,也提供了合金材料的高模量性能。
本发明以上实施例具有以下有益效果:
(1)ABS的用高光泽的LG121H,确保了材料的高光泽性;
(2)ABS接枝马来酸酐,可以提高ABS于PBT的相容性,从而更有效的提高材料的机械性能和外观效果;
(3)增韧剂MBS可以很好的提高材料的韧性;
(4)碳纤维增能够有效的提高合金材料的机械强度;
(4)制备过程工艺简单,生产工艺容易控制。
以上对本发明所提供的一种碳纤维增强PBT/ABS合金及其制备方法进行了详细介绍,本文中应用了具体个例对本发明的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本发明的方法及其核心思想;同时,对于本领域的一般技术人员,依据本发明的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本发明的限制。
