The invention relates to the technical field of traffic paint and in particular relates to hot-melt traffic paint and a preparation method thereof. According to the paint, multiple functional aids areselected to be combined to be used, the wear resistance, cracking resistance, corrosion resistance and antifouling property of the paint are improved. The primer paint can be well combined with the ground, so that pavement micro-pores are closed, the variation of the pavement and traffic line deformation under high-temperature or high-pressure conditions can be balanced, cracking even drop of thetraffic line caused by the variation of the deformation is reduced, and the mind-set of improving the cracking resistance, drop and other inner performances of the traffic line by adjusting the components and doses of various aids in the paint only in the traditional paint is broken; coloring pigments and auxiliary luminous materials are added into intermediate paint layer to serve as a traffic sign luminous layer and are combined with the surface paint to be used; glass beads are added into the surface paint, so that the reflective refraction of the coating is improved. Due to rare-earth high polymer photoluminescence materials and nano fluorescent particles in the intermediate layer and the surface layer, the visibility of the traffic line is obviously improved.
