Preparation method of nylon 66 material

The invention discloses a preparation method of a nylon 66 material. The preparation method comprises the following steps: (1) uniformly mixing modified polypropylene fiber, polytetrafluoroethylene, an auxiliary agent and nylon 66 resin in a high-speed mixer to obtain a mixed material; and (2) uniformly mixing the mixed material uniformly mixed in the step (1) and the dispersing agent again, and then putting the mixture into a double-screw extruder for extrusion granulation to obtain the nylon 66 material. According to the method, the modified polypropylene fiber, the polytetrafluoroethylene and the auxiliaries are added and reasonably compounded, so that the prepared nylon 66 material has good tensile property, thermal stability and acid and alkali resistance, and is very suitable for the field of chemical equipment. 本发明公开了一种尼龙66材料的制备方法，包括以下步骤：（1）把改性聚丙烯纤维、聚四氟乙烯、助剂和尼龙66树脂置于高速混合机中混合均匀得混合物料；（2）把步骤（1）混匀的混合物料和分散剂再次混匀后置于双螺杆挤出机中进行挤出造粒获得尼龙66材料。该方法通过添加改性聚丙烯纤维、聚四氟乙烯和助剂，并通过合理复配，使得制备的尼龙66材料具有很好的拉伸性能、热稳定性以及耐酸碱性，非常适用于化工设备
