The invention discloses an anti-skid automobile brake pedal. The automobile brake pedal is wrapped with an anti-skid material. The anti-skid material comprises the following raw materials in parts by weight: 30-50 parts of a polypropylene resin composition, 5-8 parts of asbestos fiber, 1-5 parts of an anti-aging agent, 5-10 parts of a plasticizer, 3-7 parts of a thickening agent, 5-10 parts of antiskid particles, 1-5 parts of white carbon black, 30-40 parts of BR natural rubber, 5-10 parts of a polyurethane elastomer, 2-5 parts of a dispersant and 3-6 parts of a composite stabilizer. By adding and reasonably matching various raw materials and adding the anti-aging agent, the anti-skid particles, the plasticizer and the polyurethane elastomer, the raw materials can be fully contacted and fused, so that the anti-skid material has relatively high wear resistance and anti-skid performance, and when the anti-skid material is used on the brake pedal, the driving safety can be effectively improved, the requirement of current development is met, the fatigue strength is high, the injection molding process is simple, the machining efficiency is high, the defective rate is low, and the product percent of pass is high.
