The invention relates to a fluorine-free flame-retardant PC/ABS resin composition and a preparation method and application thereof; the resin composition comprises the following components in parts by weight: 70-90 parts of PC resin, 5-10 parts of ABS resin, 8-12 parts of phosphazene flame retardant, 2-5 parts of toughening agent, 3-5 parts of carbon-forming fiber, 1-3 parts of melt enhancer, 0.5-1.5 parts of organosilicon flame retardant, and 0.5-1.5 parts of auxiliary agent. After fully stirring and mixing the above raw materials in a high-speed mixer, the materials are melted and compounded under the conveying, shearing and mixing of screws in a twin-screw extruder, and then subjected to extrusion, strand drawing, cooling and pelletizing to obtain the fluorine-free flame-retardant PC/ABS resin composition. Compared with the prior art, the resin composition not only has stable flame retardancy but also excellent mechanical properties, can meet the PFAS ban, and is very suitable for OA (office equipment), new energy batteries, electrical and electronic, home appliances and other fields.
