Abstract
The present disclosure provides a composite decorative board having a multi-layer structure. The composite decorative board may include a substrate layer. The substrate layer may include at least one first structural layer and at least one second structural layer. The second structural layer may be disposed on the first structural layer. The first structural layer may be an elastic layer, and a component of the first structural layer may include a plasticizer. The second structural layer may be a rigid layer. Thermal expansion and cold contraction of other layers of the composite decorative board may be effectively matched by setting the elastic layer and the rigid layer on the substrate layer, which may effectively improve a stability, a warpage deformation, and a contraction-expansion of the composite decorative board.
