All-weather marking for rainy nights and preparation method thereof

The invention provides an all-weather marking for rainy nights and a preparation method thereof, belonging to the technical field of road markings. The all-weather marking for rainy nights comprises a hot melting coating layer, reflective beads for rainy nights and glass beads, wherein the reflective beads for rainy nights and the glass beads are dispersed on the surface of the hot melting coating layer; the refractive index of the glass beads is greater than or equal to 1.5; each reflective bead for rainy nights comprises a spherical inner core and a ceramic particle surface layer adhered to the surface of the spherical inner core, and the refractive index of each reflective bead for rainy nights is greater than or equal to 1.9; and the content of the reflective beads for rainy nights is larger than or equal to 300 g/m , and the content of the glass beads is larger than or equal to 600 g/m . According to the road marking, the reflective beads for rainy nights with the refractive index larger than or equal to
