Long-life reactive asphalt cold patch material

The invention discloses a long-life reactive asphalt cold patch material in the technical field of asphalt cold patch materials. According to the invention, a triazine structure is introduced into the polyurethane reactive asphalt cold patch material for modification, and the triazine structure is stable and also has an anti-ultraviolet effect. The phase change energy storage microcapsule with a core-shell structure is added into the cold patch material to regulate and control the temperature of a repaired part, so that the temperature change of the asphalt cold patch material tends to be stable, the service life of the asphalt cold patch material is prolonged, a shell can form a stable hydrogen bond with a triazine structure, and the dispersion is more uniform. The phase change energy storage microcapsule can accelerate the volatilization of the diluent, so that the asphalt cold patch material is rapidly cured. The nano nickel oxide solution is added into the asphalt cold patch material, so that the mechanic
