The invention discloses an antique-imitating weathering effect manufacturing method for solid wood, which solves the problems that an existing solid wood antique-imitating weathering effect manufacturing process is time-wasting, labor-wasting and high in labor cost, and a product is not good in antique-imitating weathering effect. The antique-imitating weathering effect manufacturing method comprises the following steps: (1) selecting corresponding solid wood raw materials according to the practical needs, putting the solid wood raw materials and steel shots into a shot blasting cleaning machine, and processing the solid wood raw materials through the shot blasting cleaning machine and the steel shots; (2) roasting the processed solid wood raw materials; (3) obtaining a molded product after roasting, and performing surface protective treatment on the molded product surface to obtain a solid wood product with an antique-imitating weathering effect. According to the antique-imitating weathering effect manufacturing method for the solid wood, the solid wood can have the antique-imitating weathering effect without manual processing, so that the production efficiency is improved, the batched antique-imitating weathering manufacturing of the solid wood is realized and the labor cost is reduced. Moreover, the solid wood is good in antique-imitating weathering effect and high in aesthetic sense and artistry. The antique-imitating weathering effect manufacturing method is very suitable for being popularized and applied.
