The invention discloses an antistatic polypropylene material and a preparation method thereof. The antistatic polypropylene material comprises, by weight, 30 to 80 parts of co-polypropylene, 5 to 20 parts of ethylene propylene diene monomers, 10 to 30 parts of talcum powders, 1 to 5 parts of coupling agents and 0.1 to 5 parts of antistatic agents. Each raw material is weighed according to the proportion and the raw materials are uniformly mixed and subjected to a melt mixing and an extrusion granulation to obtain the antistatic polypropylene material. The antistatic polypropylene material has the advantages that a good antistatic property is achieved, simultaneously the tensile strength, the flexural strength, the flexural modulus and the impact strength can meet requirements, and automotive upholsteries of side boards outside a driver's seat, small cover caps, side board inner plates, inner side board plastic parts, side boards outside a passenger seat, door plank armrest frameworks, door panel plaque frameworks, door panel plaques and the like can be manufactured by the material in an injection molding process.
Description
technical field [0001] The invention relates to a plastic material and a preparation method thereof, in particular to an antistatic polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene, abbreviated as PP, was first put into industrial production in Italy in 1957 and is another important plastic species after polyethylene (PE). It has good heat resistance, and it will not be destroyed when it is cooked at 135°C for 1000 hours. The specific heat capacity and thermal conductivity of PP are smaller than that of PE, but its thermal insulation is better than that of PE. PP is a non-polar polymer with excellent dielectric and electrical insulation properties. The electrical properties are basically not affected by ambient humidity and electric field frequency. Within the allowable operating range, the increase in temperature will reduce the electrical properties. Its High arc resistance. PP has good chemical resistance, and other re...
