Description
【技术领域】
本发明涉及尼龙颗粒制备技术领域,具体涉及一种增韧尼龙颗粒及其制备方法。
【背景技术】
聚酰胺(PA,俗称尼龙)是美国DuPont公司最先开发用于纤维的树脂,于 1939年实现工业化。20世纪50年代开始开发和生产注塑制品,以取代金属满足下游工业制品轻量化、降低成本的要求。聚酰胺主链上含有许多重复的酰胺基,用作塑料时称尼龙,用作合成纤维时我们称为锦纶,聚酰胺可由二元胺和二元酸制取,也可以用ω-氨基酸或环内酰胺来合成。根据二元胺和二元酸或氨基酸中含有碳原子数的不同,可制得多种不同的聚酰胺,聚酰胺品种多达几十种,其中以聚酰胺-6、聚酰胺-66和聚酰胺-610的应用最广泛。但聚酰胺还存在韧性、强度、抗氧性等缺点,作为结构材料使用时受到了很大限制。
【发明内容】
为了克服上述的问题,我们研制了一种增韧尼龙颗粒及其制备方法,以解决上述背景技术中提出的不足。
为了实现上述目的,本发明采用的技术方案:一种增韧尼龙颗粒,其包括以下重量份的组分:聚酰胺树脂50-70份、增韧剂15-25份、增强剂5-10份、增容剂2-4份、偶联剂1-2份、抗氧剂0.5-1份、防粘剂0.1-0.5份。
于一个或多个实施案例中,所述增韧剂为POM、PVC、PET或者PETG中的一种或多种。
于一个或多个实施案例中,所述增强剂为玻璃纤维、有机纤维或者石棉。
于一个或多个实施案例中,所述增容剂为乙烯-丙烯酸酯共聚物。
于一个或多个实施案例中,所述偶联剂为钛酸酯类偶联剂。
于一个或多个实施案例中,所述防粘剂为芥酸酰胺、油酸酰胺或乙撑双硬脂酰胺中的任意一种或者几种的组合物。
一种增韧尼龙颗粒的制备方法,包括以下步骤:
步骤一、按照配方称取聚酰胺树脂、增韧剂、增强剂、增溶剂、偶联剂、抗氧剂和防粘剂;
步骤二、将上述各组分加入搅拌机中混合均匀,得到物料一;
步骤三、将物料一加入双螺杆挤出机中,挤出机从加料口到机头的各段螺杆温度设置在150℃-250℃之间,物料一经熔融塑化、捏合混炼、机头挤出、水环切粒、冷却、脱水、鼓风干燥后得到成品。
本发明同背景技术相比所产生的有益效果:
通过采用上述技术方案,本发明的增韧尼龙颗粒及其制备方法以聚酰胺树脂为主体材料,采用了增韧剂以及增强剂对聚酰胺树脂进行增韧增强,而POM、 PVC、PET或者PETG的增韧效果好,玻璃纤维、有机纤维或者石棉的增强效果好,并且还采用了抗氧剂、防粘剂等材料,可以提升材料的综合性能,且还具有制造成本低,工艺简单等优点。
