The invention belongs to the technical field of polymer materials, and relates to a 5VA high-flame-retardant ABS resin composition and a preparation method thereof. The resin comprises the following components and contents (parts by weight): 65-75 parts of ABS resin; 3-8 parts of chlorinated polyethylene; 15-20 parts of aromatic brominated flame retardant; 3-6 parts of antimony-based flame-retardant synergist; 3-6 parts of nano carbon-forming masterbatch; 0.1-0.5 part of anti-dripping agent; 0.2-0.5 part of antioxidant; 0.5-1.0 part of light stabilizer; 0.5-1.0 part of lubricant. After fully stirring and mixing the above raw materials in a high-speed mixer, the materials are melted, compounded, homogenized, drawn, cooled and pelletized under the conveying, shearing and mixing of screws in a twin-screw extruder to obtain the 5VA high-flame-retardant ABS resin composition. Compared with the prior art, the invention solves the problems of poor thin-wall 5VA flame retardancy and low impact properties of flame-retardant ABS resins, is suitable for meeting the requirements of 5VA high flame retardancy, and is also suitable for applications complying with the flame-retardant S.2 needle flame combustion standard.
