The invention discloses a mosquito-repellent, anticorrosive and antibacterial processing process for a rosewood fan rib, and belongs to the field of a folding fan bamboo material processing process. The mosquito-repellent, anticorrosive and antibacterial processing process is characterized by comprising steps of preparing an antibacterial and anticorrosive solvent and antibacterial and anticorrosive cooking materials, cooking the materials, spraying the cooked materials, and carrying out smoke curing. Besides, a surfactant, a detergent dispersant and sodium carboxymethyl cellulose are added into the antibacterial and anticorrosive solvent, so that all antibacterial and anticorrosive components are fused consistently, and therefore, the antibacterial and anticorrosive effects are maximized and optimized under synergistic effect. According to the mosquito-repellent, anticorrosive and antibacterial processing process, the antibacterial and anticorrosive solvent and the antibacterial and anticorrosive cooking materials are all selected from pure natural materials, are not only low in procurement cost, but also good in mosquito-repellent, anticorrosive and antibacterial effects, and are nonhazardous on environment and a human body. The mosquito-repellent, anticorrosive and antibacterial processing process can be used for effectively carrying out anticorrosive processing on the rosewood fan rib of a folding fan, so that the rosewood fan rib is durable in use, not liable to crack and return oil; and material performance indexes of the rosewood fan rib are greatly improved, antibacterial and heath effects are achieved, and negative ions which are beneficial to the human body can be emitted.
