The utility model discloses a wide-temperature weather-proof EVA front wall protection plate, which relates to the technical field of automobile body structures, and comprises an EVA protection plate body, the outer side of the EVA protection plate body is coated with a wide-temperature weather-proof
coating, the wide-temperature weather-proof
coating comprises a weather-proof shielding layer, a mechanical enhancement layer and a base material bonding layer, the outer side of the EVA protection plate body is coated with the base material bonding layer, and the weather-proof shielding layer is coated with a weather-proof shielding layer. And the outer side of the base material bonding layer is coated with the mechanical enhancement layer. According to the utility model, the three
layers of composite coatings are subjected to material performance gradient design, a cross-layer energy dissipation network and interface chemical bonding reinforcement, so that a wide-temperature weather-proof
protection system of outer shielding, middle buffering and inner anchoring is constructed. In circulation at the temperature
ranging from-40 DEG C to 80 DEG C, all the
layers play an
independent function, overall performance
gain is formed through component interpenetration and structure
synergy, the service life of the front wall protection plate in severe environments such as extremely cold high temperature, rain,
snow, salt mist and the like is prolonged, and the scheme is remarkably superior to a traditional single-layer
coating scheme.
