Double-interface treatment thermal insulation decorative plate

The utility model relates to the technical field of decorative plates, and provides a double-interface treatment heat preservation decorative plate which sequentially comprises a backing, a heat preservation material layer, an adhesive layer, an inorganic composite plate layer, an interface treatment layer, a primer layer and a facing layer from inside to outside. The interface treatment layer comprises a water-based interface treatment layer and a UV permeation treatment layer. After double matching treatment of the water-based interface treatment layer and the UV permeation treatment layer, the adhesive force of the calcium silicate board and the facing primer can reach grade 0, the tensile property of the decorative panel is improved by two times, the safety performance of the whole decorative board system is further improved, and the risk that the outer wall facing layer falls off is reduced. Meanwhile, the waterproof performance of the whole decorative plate system is higher, and the decorative plate sys
