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尼龙料复配组合物的制备工艺。
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。
