The invention provides a weatherproof flexible veneer, which comprises a nonwoven fabric layer, a polyurethane (PUR) hot melt adhesive layer, a wood solid veneer layer, a water-based coloring layer, a PUR hot melt adhesive paint layer and an ultraviolet (UV) finish paint layer, wherein the nonwoven fabric layer is bonded with the solid wood veneer layer through the PUR hot melt adhesive layer, and the water-based coloring layer, the PUR hot melt adhesive paint layer and the UV-side paint layer are sequentially coated on the upper surface of the solid wood veneer layer. The weatherproof flexible veneer has good flexibility and does not crack and prevents the paint from peeling off after being bent for multiple times, the adopted synthesized materials can meet the international environment-friendly requirement, a traditional paint technical is changed, no pollution is led to an application environment, the utilization rate of the paint is high, the weatherproof flexible veneer is free from being delaminated at a high temperature and being embrittled at a low temperature, has excellent properties such as ultraviolet resistance, aging resistance and water resistance and can be made into a veneer synthesized material which can be continuously coiled, and the requirement on elongation and mass production of the material can be met.
