Abstract

The invention discloses a high-performance pipe and a preparation method thereof. The high-performance pipe contains polypropylene, graphene oxide grafted styrene and graphite fluoride. The high-performance pipe also contains an impact modifier, calcium carbonate, an antioxidant and a wetting agent. The composition comprises the following components in parts by weight: 50-120 parts of polypropylene; 0.5 to 5 parts of graphene oxide grafted styrene; 0.5 to 5 parts of graphite fluoride; 10 to 30 parts of an anti-impact modifier; 1 to 3 parts of antioxidant; 2 to 10 parts of calcium carbonate; and 1 to 4 parts of wetting agent. The graphene oxide grafted styrene and the graphite fluoride are added into the polypropylene, so that the resistivity of the pipe is reduced, and the antistatic effect is improved. Meanwhile, the graphene oxide grafted styrene also improves the strength of the pipe.

Description

technical field [0001] The invention relates to the technical field of power tubes, in particular to a high-performance tube material and a preparation method thereof. Background technique [0002] Polypropylene (PP) has a high melting point and excellent comprehensive properties. It is one of the most promising thermoplastic polymer materials today. Compared with other general-purpose thermoplastics, it has low density, good rigidity, high strength, flex resistance, and outstanding Excellent stress crack resistance, good heat resistance, electrical insulation and chemical resistance, and rich sources of raw materials, low price, easy to process and shape, so polypropylene is widely used in power pipes. Power pipes can also be referred to as pipes for short, which are products obtained by hot extrusion of polypropylene. But the antistatic performance of the power tube described in the prior art is relatively poor. [0003] Therefore, aiming at the deficiencies of the prior...
