Permanent antistatic PP composite material with excellent mechanical properties and preparation method thereof

The invention provides a permanent antistatic PP composite material with excellent mechanical properties and a preparation method thereof. The permanent antistatic PP composite material comprises the following components in parts by weight: 55-95 parts of PP, 0-10 parts of an antistatic aid, 0-20 parts of a filler, 0-15 parts of a flexibilizer and 0.1-5 parts of other aids. The preparation method of the permanent antistatic PP composite material comprises the following steps: weighing the components according to the weight ratio, mixing in a high-speed mixer for 4-6 minutes, feeding into a twin-screw extruder from a hopper, melting, homogenizing, extruding and granulating to obtain the permanent antistatic PP composite material. Compared with the prior art, the material has the advantages of long-acting antistatic effect and excellent mechanical property, can be subjected to color matching, and can be widely applied to automobile parts with antistatic requirements. 本发明提供了一种力学性能优异的永久抗静电PP复合材料及制备方法，该材料包括以下组分和重量
