The invention provides a high-wear-resistant polypropylene composite material used for automobile interior trim and a preparation method of the polypropylene composite material. The polypropylene composite material is made from, by weight, inorganic filling materials, polypropylene, a toughening agent, a wear-resisting agent, an anti-oxidant, a lubricant, a light stabilizer and toner. The preparation method comprises pre-treating a wear-resisting agent, putting the raw materials in a high-speed mixer according to a certain ratio for uniform mixing, putting the obtained mixture in a double screw extruder, and performing melt extrusion and granulation to obtain the high-performance polypropylene composite material. Based on a basic formula of a polypropylene composite material, proper alumina is taken as the wear-resisting agent, and subjected to pre-treatment. The prepared polypropylene composite material is good in wear resistance and low in smell, and has mechanical properties meet index requirement. The preparation method is simple, and is low in cost and wide in application range.
