The invention belongs to the technical field of wood modification, in particular relating to a method for producing rubber tree carbonized wood by resin pretreatment. The method comprises the following steps: putting the rubber saw wood of which the water content is less than 15% in a vacuum treatment tank for impregnating; then, stacking and airing the wood, putting the wood in a kiln, routinely drying the wood in the kiln until the water content is less than 12%, and then, taking the wood out of the kiln; and putting the obtained wood in heat treatment equipment for high-temperature heat treatment, and taking the wood out of the kiln to obtain the rubber tree carbonized wood, wherein the water content of the wood is 4-6%. The invention has simple processes, high heating rate in the heat treatment process and high production efficiency, can increase the strength of the rubber tree carbonized wood by vacuum pressurization and impregnation of resin, and can effectively prevent the wood from deforming and cracking in the heat treatment process. The obtained rubber tree carbonized wood has the advantages of little loss of strength of the wood, elegant color, more excellent dimensional stability and durability and the like, and can be widely used for indoor and outdoor floors, landscapes, decorative materials and the like, thereby widening the application field of the rubber tree wood and increasing the additional value of the rubber tree wood.
