The invention discloses an energy-saving thermal insulation anti-seismic integrated wallboard. A decorative board is a multi-layer composite board, a surface layer is a fluorocarbon paint, a middle layer is a calcium silicate board, an inner layer is an insulation layer, and the insulation layer is sandwiched by a thin plate. The thin plate is an environment-friendly thermal insulation decorativecomposite board with high compression resistance, no water absorption, moisture resistance, air resistance, light weight, corrosion resistance, long service life and low thermal conductivity and the like. An uv-curable penetrating agent and a fiber reinforced calcium silicate board or a fiber cement with strong penetration, rapid infiltration, deep penetration, deep curing film can be solved, anda three-dimensional chemical network crosslinking reaction can be formed with an UV putty, an UV sealing paint. The adhesion problem of a decorative surface layer and the base plate can also be solved. The invention also provides a flame retardant material. Adhesion properties of an anti-flaming decorative board prepared by the method of the composite exterior decorative panels meet the requirements of the national standard and gives the base material the flame-retardant property; moreover, mechanical properties of the base material can not be influenced, and the formaldehyde emission is alsoabove E1 level, is safe and environmentally-friendly. At the same time, the natural texture of wood is kept, and decorative effect is good.
