The invention discloses a manufacturing process of a composite paint-free thin-coating wood veneer. The process is realized through the following steps sequentially that step 1, a wood veneer is prepared, step 2, compounding and shaping are conducted, step 3, sanding and coloring are conducted, step 4, deburring and drying are conducted, step 5, gluing and drying are conducted, step 6, coating andcuring are conducted; step 7, light-polishing is conducted, and step 8, sealing wax and storing are conducted. According to the manufacturing process of the composite paint-free thin-coating wood veneer, the wood veneer manufactured has the outstanding characteristics of environmental protection, high flame retardancy, high wear resistance, strong water resistance and the like, in addition, due to the fact that a thin glue layer and an is adhesive film layer are arranged on the surface layer of the wood veneer, original wood grains of a log skin can be touched on the surface of the wood veneer, the vertical physique feeling of the log skin and the original and natural characteristics of the log skin can be further embodied, in addition, the manufacturing process of the composite paint-free thin-coating wood veneer has the advantages that the production process is greatly simplified, resources can be further saved, the production cost of production enterprises can be reduced, and themarket competitiveness of the production enterprises can be improved.
