Preparation and Properties of Hot-Melt Road Marking Paint
In this paper,a hot melt road marking paint is prepared by using C5 petroleum resin as the film forming resin in addition to titanium dioxide,glass beads,heavy calcium and talcum powder as the filler and and other additives.The effects of different resins,titanium dioxide,filler,plasticizer and their dosage on the properties of the road marking paint are studied.The analysis of the softening point,compressive strength,retro reflection coefficient and wear loss of the coating reveals that the synthesized hot-melt road marking paint shows good properties such as short drying time,appropriate softening point,good flexibility,excellent wear resistance,good retro reflection performance,strong water resistance and acid/alkali resistance when 20％C5 petroleum resin,5％titanium dioxide,22％glass bead,1％plasticizer and 4％other additives are used in the paint.
