[0019] The second scratch-resistant layer 3 is arranged between the top surface of the base layer 1 and the bottom surface of the thermal repair layer 2, which is beneficial to isolate the base layer 1 and the thermal repair layer 2 and enhance the penetration resistance of the overall coating, providing higher protection for the base layer 1;

[0020] The thermal repair layer 2 is a polyurethane elastic coating, which is beneficial to absorbing pressure and deforming under pressure and restoring when heated, thereby improving the scratch resistance and self-restoring when heated;
