Development of high performance hot melt road marking coatings for expressways
In order to solve the problems of peeling off,poor wear resistance and substandard reflection of current marking coatings,high performance hot melt marking coatings for highway were developed.The effects of modified C5 resin,modified inorganic powder and modified quartz sand ratio on the microstructure,compressive strength,softening point,wear resistance and adhesion of the coating were analyzed through laboratory tests.The results show that the high performance hot melt road marking coating combines inorganic components and organic resin closely through the strong interaction of chemical bond,which eliminates the shortcomings of brittleness and non-pressure resistance of common marking coatings.All the compressive specimens of the coating did not have brittle fracture,but had yield deformation under high toughness,and the softening point,wear resistance and adhesion of the coating samples were better than that of ordinary hot melt marking,which can improve the impact resistance,aging resistance and visibility of highway marking.
