The invention provides a chemical cabinet cutting process. The chemical cabinet cutting process specifically includes: cabinet body cutting and forming, cabinet door cutting and mounting, flame-retardant and corrosion-resistant layer preparation and flame-retardant and corrosion-resistant layer lamination. Compared with the prior art, the chemical cabinet cutting process has the advantages that cabinet body cutting and cabinet door cutting are performed sequentially, integral cabinet body processing is performed through a bending machine, and accordingly cabinet body sealing performance is guaranteed effectively, and the overall safety of the chemical cabinet is increased; by using polypropylene resin, polyethylene glycol diacrylate, ethyl triethoxysilane and disproportionated potassium rosinate as the raw materials, the strong acid and strong base resistance of the corrosion-resistant layer is increased effectively, and the overall corrosion resistance and safety are increased greatly; by using a flame-retardant liquid impregnating manner, the corrosion-resistant layer is also flame-retardant, and accordingly the flame retardance inside the chemical cabinet is improved, fire can be prevented effectively, and life and property safety is guaranteed.
