| description | The invention discloses a preparation method of an ultraviolet light-sensitive reversible color-changing coating for road pavement identification, and a practical application of the ultraviolet light-sensitive reversible color-changing coating for road pavement identification in road engineering. The preparation method comprises the following steps: grinding op powder, PS plastic particles, fluorescent powder and titanium dioxide powder to 6-12 [mu] m, mixing to prepare an ultraviolet light sensation reversible color-changing pigment filler, adding the pigment filler into a mixed emulsion formed by mixing bimolecular polyurethane resin and a polyurethane diluent according to a ratio of 1.5: 1, heating to 40 DEG C at a constant temperature, pre-stirring, adding a tetrahydrofuran (THF) solvent, a coalescing agent (dicyclopentenyl oxyethyl acrylate), a dispersing agent (triethylhexyl phosphoric acid) and a modifier (an antioxidant and a light stabilizer), and fully stirring to obtain thecoating. The method has t |
