Description

一种ABS与ASA共聚物合金及其制备方法
(一)技术领域
本发明涉及一种ABS与ASA共聚物合金以及该合金的制备方法。 
(二)背景技术
由于ABS中含有不饱和的双键，因而制成的材料容易受日光中的紫外线照射而迅速变黄，不利于室外或光照环境下等耐候性要求更高的环境下长期使用。 
(三)发明内容
为了克服现有ABS的上述不足，本发明提供一种耐候性更好、冲击强度高、流动性好的ABS与ASA共聚物合金，并提供其制备方法。 
本发明解决其技术问题的技术方案是：一种ABS与ASA共聚物合金，其由下列组份组成： 
30～40质量份的ABS； 
60～70质量份的ASA； 
5～10质量份的增韧剂； 
0.2～0.5质量份的抗氧剂； 
0.2～0.5质量份的润滑剂。 
所述的增韧剂可以为甲基丙烯酸甲酯-丁二烯-苯乙烯共聚物或乙烯-丙烯酸酯-马来酸酐三元共聚物或乙烯-丙烯酸酯-甲基丙烯酸缩水甘油酯三元共聚物或3-甲氧基-3-甲基-1-丁醇； 
所述的抗氧剂可以为抗氧剂1010或抗氧剂168； 
所述的润滑剂可以为乙撑双硬脂酸酰胺或廿四酸蜡酯或褐煤酸酯 蜡。 
上述ABS与ASA共聚物合金的方法：按照配比将原料配齐，将原料搅拌均匀后加入双螺杆挤出机中，双螺杆挤出机中设有八个温度设定区，一区的加工温度为220℃，二区的加工温度为230℃，三区的加工温度为235℃，四区的加工温度为240℃，五区的加工温度为240℃，六区的加工温度为230℃，七区的加工温度为230℃，八区的加工温度为230℃，主机转速为200～300转/分钟；原料经挤出后冷却、干燥、切粒即得共聚物合金。 
本发明的有益效果在于：ASA为丙烯腈、苯乙烯、丙烯酸酯三元共聚物，其中不含不饱和双键的丙烯酸橡胶替代了ABS中含有不饱和双键的丁二烯橡胶，因此，不但可抵抗紫外线引起的降解、老化、褪色，还可抵抗大气中的氧化、加工过程中的高温引起的分解或变色，由ABS和ASA及其它添加剂制成的ABS/ASA合金的耐候性有了很大的提高，且冲击强度高、流动性好。
