Problems solved by technology

[0004] For another example, the current improvement methods for improving the nighttime visibility and rainy day visibility of marking paint are usually achieved through the traditional method of adding reflective materials such as ordinary glass beads, but conventional reflective materials such as glass beads are usually All of them exist in the marking paint in granular form. During use, the reflective material will fall off due to the abrasion of vehicle tires and road cleaning operations, which will significantly reduce the reflective effect and service life of the marking. Frequent refurbishment of marking lines

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of marking paint, in particular to a hot-melt marking paint and a preparation method thereof. Background technique [0002] Road marking paint is a kind of safety mark and a "special voice". The traffic safety management department uses road marking paint to delineate vehicle driving lanes and channelize traffic, so as to strengthen traffic safety management, reduce vehicle and personal accidents and beautify purpose of urban roads. Therefore, the performance requirements for road marking paint are relatively high, and usually require quick drying, visibility, anti-rutting, low-temperature and high-temperature resistance, wear resistance, rain reflective properties, etc., and with the continuous increase in the number of vehicles In order to prolong the service life of the marking paint and prolong the replacement cycle, it is usually required that the marking paint has good antifouling performance, and eve...
