The utility model relates to the technical field of road marking, in particular to an all-weather temporary road marking belt. The all-weather temporary road marking belt comprises a bearing body layer formed through extrusion and a thermoplastic elastomer layer arranged on the upper surface of the bearing body layer, a water-soluble adhesive layer is arranged on the upper surface of the thermoplastic elastomer layer, and reflective particles are scattered on the water-soluble adhesive layer. Two oppositely-arranged metal meshes are arranged on the lower surface of the bearing body layer in the length direction of the marking belt, and water-soluble glue is coated between the upper surfaces of the metal meshes and the lower surface of the bearing body layer; the lower surface of the metalmesh is coated with a pressure-sensitive adhesive, and release paper covers the lower portion of the pressure-sensitive adhesive. The all-weather temporary road marking belt is convenient to construct, can be laid without heating, is convenient to replace or withdraw, and has high tensile strength.
