Description

一种玻璃纤维增韧的复合尼龙料
技术领域
    本发明涉及尼龙材料领域，确切地说是一种玻璃纤维增韧的复合尼龙料。
背景技术
由于尼龙具有很多的特性，因此，在汽车、电气设备、机械部构、交通器材、纺织、造纸机械等方面得到广泛应用。
随着汽车的小型化、电子电气设备的高性能化、机械设备轻量化的进程加快，对尼龙的需求将更高更大。特别是尼龙作为结构性材料，对其强度、耐热性、耐寒性等方面提出了很高的要求。尼龙的固有缺点也是限制其应用的重要因素，特别是对于PA6、PA66两大品种来说，与PA46、PAl2等品种比具有很强的价格优势，虽某些性能不能满足相关行业发展的要求。因此，必须针对某一应用领域，通过改性，提高其某些性能，来扩大其应用领域。 由于PA强极性的特点，吸湿性强，尺寸稳定性差，但可以通过改性来改善。
发明内容
为了缓解现有技术的不足和缺陷，本发明的目的在于提供强度高的一种玻璃纤维增韧的复合尼龙料。
上述目的通过以下方案实现：
一种玻璃纤维增韧的复合尼龙料，其特征在于，其是由下述重量份的原料造粒制得：
改性尼龙PA66 59-61，尼龙PA6 49-51；
所述的改性尼龙PA66由下述重量份的原料造粒制得：抗氧剂1010  0.5-0.8，抗氧剂168  0.1-0.3，聚己内酯 3-4，硅油0.2-0.4，硅烷偶联剂KH550  1-2，硬脂酸锌0.8 -1.5，硬脂酸钙0.1-0.5，氧化聚乙烯蜡1.5-2，玻璃纤维8-10，尼龙PA66  70-71，ASA树脂 8-10，改性膨胀蛭石粉6-8；
所述的改性膨胀蛭石粉的制备方法为：
将膨胀蛭石于400-500℃下烧损2-4小时，后磨粉，再用浓度为10-15%的乙酸溶液浸泡3-4小时，再用去离子水洗涤至中性，烘干后，加入相当于粉体重量2-4%的硅烷偶联剂KH560搅拌均匀，烘干，粉碎成粉末，即得。
所述的一种玻璃纤维增韧的复合尼龙料，其特征在于，制造方法为：
（1）取制备改性尼龙PA66所需原料中的除玻璃纤维以外各原料，按照重量份置于高混机中混合3-6min，得到的混合物经主喂料口加入双螺杆挤出机中，玻璃纤维从侧喂料口按重量份加入双螺杆挤出机，控制加工温度在255-265℃，螺杆转数在400-500rpm，熔融后挤出造粒即得到改性尼龙PA66；
（2）按照重量份将改性尼龙PA66与尼龙PA6置于高混机中混合3-5min，得到的混合物经主喂料口加入双螺杆挤出机中，控制加工温度在260-270℃，螺杆转速在400-490rpm，熔融后挤出造粒即得到产品。
本发明的有益效果为：
本发明解决了现有尼龙材料普遍强度低等性能缺陷，玻璃纤维对尼龙材料具有很好的增强效果，与其余原料复合，所得产品质量稳定，提高了生产效率，降低了生产成本。改性膨胀蛭石粉的添加可以很好的增强本发明的尺寸稳定性。
