The invention discloses a high-strength plastic bumper which comprises an arc-shaped plastic base body. The arc-shaped plastic base body is formed by mixing polypropylene, toughening agents, anti-aging agents and filling agents in an injection molding mode. A layer of reinforcing screen cloth is arranged in the arc-shaped plastic base body, and is mesh fabric made of glass fibers or polyimide fibers. According to the weight ratio of the components in the arc-shaped plastic base body, the polypropylene accounts for 69-72 parts, the toughening agents account for 9-12 parts, the anti-aging agents account for 3-6 parts, and the filling agents account for 11-14 parts. In this way, the reinforcing screen cloth is specially arranged in the high-strength plastic bumper, so that overall strength is increased, the tearing resisting performance is excellent, completeness of the bumper is improved in a slight impact, and maintenance costs are reduced.
