The invention relates to reconstituted decorative veneer, in particular to functional paint-free decorative finish reconstituted decorative veneer and a manufacturing method thereof, and belongs to the wood processing industry. The functional paint-free reconstituted decorative veneer is characterized by sequentially comprising a transparent abrasion-resistant surface film adhesive paper layer, a reconstituted decorative veneer layer, an adhesive layer and a flexible reinforcing material layer from up to down, wherein the thickness of the reconstituted decorative veneer layer is 0.15 to 1.00 mm; the thickness of the flexible reinforcing material layer is 0.05 to 0.15 mm; the transparent abrasion-resistant surface film adhesive paper layer is a film adhesive paper layer formed through steeping transparent abrasion-resistant surface paper in an amino-formaldehyde resin glue solution containing tourmaline powder and AL2O3; the particle size of tourmaline negative ion powder is larger than 500 meshes; and the negative ion count quantity in the Geiger. Muller zone is larger than 3000 ions/cc. According to prepared the paint-free decorative finish reconstituted decorative veneer, the surface abrasion value is smaller than 50 mg/100r under the dual functions of the abrasion-resistant surface paper and AL2O3.
