Further, the primer layer adopts a water-based alkali-resistant seal primer coating, and the thickness of the primer layer is 20-50 microns, preferably 30 microns.

Furthermore, the surface paint layer adopts a water-based elastic acrylic acid protective surface paint coating, and the thickness is 30-80 microns.

Furthermore, the indicator or the decorative layer adopts a water-based elastic acrylic acid protective finish coating with the thickness of 30-80 microns.

Furthermore, the luminous coating adopts a solvent type fluorescent paint coating, and the thickness is 30-60 microns.

Further, the luminous coating can be in the shape of a strip, a belt, a corrugation, an arrow and the like, and plays a role in guiding and warning at night.

Furthermore, the shape of the indicator is arrow-shaped, and the indicator plays a role in guiding and warning in daytime.

The utility model discloses beneficial effect is showing: after the luminous coating is coated on the anti-collision wall, the geometric line shape of the highway bridge can be displayed at night through the coated luminous coating, driving at night can be guided and warned, driving safety of the bridge can be guaranteed, and the bridge landscape can be beautified. The anti-collision device is universal in applicability, can cover anti-collision walls of bridges of all length scales, changes past points into lines or surfaces, and is more visual and has warning and guiding functions. Because the coating which can independently emit light is coated, the luminous coating on the anti-collision wall can be seen even if a user rides a bicycle or walks at night, and a good safety guarantee effect can be achieved. The coating of the bridge anti-collision wall does not need too complicated process and procedure, and common workers can complete the construction operation. And through the replacement of the attached delineator of the metal product, the method is more economical and green, and the phenomenon of losing the attached delineator can not occur.
