The invention relates to the technical field of composite boards, in particular to a 
solid wood paint-free composite single board. A pressing-fit 
machine lower pressing plate, a composite single board, regenerated 
veneer and a pressing-fit part are included. The outer surface of the upper side of the pressing-fit 
machine lower pressing plate is fixedly connected with a 
hydraulic cylinder. A pressing-fit tabletop is arranged on the lower side of the pressing-fit 
machine lower pressing plate. The regenerated 
veneer is combined with 
fiber paper after being subjected to the step of water supplementing, the 
fiber paper is treated through a 
melamine glue immersing step, and after being combined with the regenerated 
veneer, the 
fiber paper is combined with a thin wood slice. Various valuable woodis selected as a 
solid wood veneer layer of the third layer, the valuable wood is planed and 
cut into the thin wood slice with 20-30 filaments, and in the actual effect, the surface 
solid wood 
pipe hole texture and 
grain quality and the abundant color and luster presentation are improved. In the fourth-layer paint glue film technology, during 
machining, through adding of aluminum 
oxide in resin,the capability of abrasion and 
scratching resisting can be improved, and practicability is improved. Integral practicability is high, and the usage effect is better compared with a traditional manner.
