The invention discloses an environmentally friendly and efficient ice-melting coating material and its preparation method and application, aiming to solve the problems of high cost of deicing, environmental pollution caused by deicing agents, harm to roads and the environment, and the technology that cannot function effectively for a long time question. The coating material is made of the following raw materials: deicing agent, bonding material, hydrophobic coating material, hydrophilic coating material, hydrophobic plasticizer, hydrophilic plasticizer, glycerin, anti-sticking agent, Talc powder, filler, semi-reinforcing agent, leveling agent, coupling agent, defoamer, porogen, hydrophobic fumed silica. And further provide a preparation method of the coating material, and apply it to ice melting of traffic roads. The invention does not contain harmful ions, does not cause corrosion and does not damage the environment when deicing for a long time, and has a better maintenance effect on the road surface; the raw material has a wide range of sources, the cost is low, the production process is simple and easy to operate, and can be popularized and applied in a wide range; It reduces a lot of manpower and material resources and has important economic value.
