Durable hot-melt two-component pavement marking coating as well as preparation method and application thereof

The invention relates to the technical field of road coatings, in particular to a durable hot-melt two-component pavement marking coating as well as a preparation method and application thereof. A durable hot-melt bi-component pavement marking coating comprises a component A and a component B, the mixing ratio of the component A to the component B is 1: 1-1.5, and the component A comprises the following components in parts by weight: 15-30 parts of filler; 24 to 36 parts of glass beads; 4-11 parts of a film forming agent; 0.1 to 0.3 part of a catalyst; the component B comprises the following components in parts by weight: 15-30 parts of filler; 1-6 parts of a cross-linking agent; 2-6 parts of a tackifier; and 0.6-5 parts of a chain extender. The bonding strength, hardness and elasticity of the hot melt marking coating are improved, the construction difficulty is reduced, the adhesiveness between the coating and glass beads is good, the surface of the coating is not prone to being contaminated by dust, the coa
