The invention relates to a material mixer for the production of road traffic safety facilities, and in particular to a material mixer for the production of pavement marking coating for road traffic safety facilities. The technical problem which the invention needs to solve is to provide the material mixer for the production of pavement marking coating for road traffic safety facilities which can save both time and labor, increase mixing efficiency and increase the efficiency of pavement marking coating production, and is easy to operate and convenient to use. In order to solve the technical problem, the invention provides the material mixer for the production of pavement marking coating for road traffic safety facilities, which comprises a base plate and the like; supporting rods are vertically connected to the left side and right sides of the top part of the base plate, a mixing tank is connected between the top ends of the two supporting rods, a hopper is mounted on the right side ofthe top part of the mixing tank, a discharging device is arranged on the bottom of the mixing tank, and a mixing device is arranged in the mixing tank. By means of the mixing device, the material mixer can rapidly mix materials for the synthesis of pavement marking coating.
