The invention relates to the technical field of ACS resins, in particular to a flame-retardant ACS resin composition and a preparation method thereof. The composition comprises the following raw materials: SAN resin, chlorinated polyethylene resin, silicone rubber compound, halogen flame retardant, flame retardant synergist, calcium-zinc stabilizer, antioxidant and lubricant. The raw materials are extruded and granulated by a twin-screw extruder at 170℃‑195℃ under a vacuum negative pressure of ‑0.1 MPa. The flame-retardant ACS resin composition of the invention can reach V0 level in flame retardancy, and also has the advantages of high impact toughness and low market price, and can be widely used in electronics, electrical appliances, communications, instruments, building materials, auto parts, office machinery and other fields.
