Abstract

The invention relates to the field of polypropylene materials and discloses a polypropylene material with metal cohesiveness, flame retardance and static electricity resistance, a preparation method of the polypropylene material, a polypropylene composite steel pipe as well as a preparation method and application of the polypropylene composite steel pipe. According to a standard MT113-1995, after naked flame is eliminated, the duration time of the flame of the polypropylene material is within 3s, the propagation length of the flame is 280mm or below, the duration time of flameless combustion is within 30 seconds, and the surface impedance of the polypropylene material is below 3*10<8>ogema; and according to a standard GB / T2791-1995, the peel strength of the polypropylene material to metal is 75N / 25mm or above. The polypropylene composite steel pipe prepared from the polypropylene material is excellent in stability and corrosion resistance and long in service life and can be applied to coal mine production.

Description

technical field [0001] The invention relates to the field of polypropylene materials used in coal mine production, in particular to a polypropylene material with metal adhesion properties and flame-retardant and antistatic properties, a preparation method thereof, and a polypropylene composite steel pipe made from the polypropylene material The preparation method thereof, and the application of the polypropylene composite steel pipe in coal mine production. Background technique [0002] At present, composite steel pipes are widely used in various fields such as coal mines, non-ferrous metal mines, power plants, and urban domestic water, such as for the transportation and filling of tailings, the transportation of fly ash, and the discharge and transportation of urban domestic water or wastewater. When this kind of composite steel pipe is used in the above fields, it is required to have excellent wear resistance, water impact resistance and corrosion resistance. At present, ...
