The invention belongs to interior building decoration materials, and relates to a production process of a solid wood composite reinforced board, which is characterized in that precious and famous woods such as black walnut, sapele, Thai pomelo, rosewood, and sandalwood are selected to make 15-25mm thick thin For wood, the slicing process is effectively reflected on the composite reinforced board of solid wood technology, and the thin wood is pasted on the density board or wooden multi-layer board, put into a hot press for pressing, and sanding machine to make a substrate, covered with trioxide The two-aluminum film wear-resistant layer is processed by hot pressing with a pressure of 200kg, a temperature of 190-200°C, and a time of 45-60 seconds to make a composite reinforced board of solid wood technology. The solid wood process composite strengthened board of the present invention is produced by hot pressing one-time forming technology. The process method is simple and can be widely used in indoor architectural decoration. It has super wear resistance, smooth paint film, strong adhesion, high transparency, acid and alkali resistance, It is flame-retardant, moisture-proof, strong, not easy to crack, not easy to violent, and low in cost.
