Fiber polymer concrete external wall board

The utility model relates to a fiber polymer concrete external wall board, which comprises a surface concrete layer and a bottom-surface heat insulation material layer. A fiber material layer is arranged inside the concrete layer and bonded and solidified with concrete through resin bonder, the concrete layer is bonded and solidified with the heat insulation material layer through bonder, and a coloring layer is arranged on the upper surface of the concrete layer. The fiber polymer concrete external wall board utilizes resin to replace cement and increases strength through mixing and bonding sandstones through reinforced fibers. The coloring layer on the upper surface of the concrete layer utilizes uvioresistant anti-corrosion resin and toner, is brighter in color without fading when compared with natural granite rock, and is wear-resistant, airtight and waterproof in surface without cracking or peeling of external wall boards caused by icing of leaked water. The bottom-surface heat insulation material layer
