The invention belongs to the technical field of polymer materials, and in particular relates to a thermostable mineral-reinforced PC/ABS resin composition and a preparation method thereof. The resin composition comprises the following components in parts by weight: 50-70 parts of PC resin, 10-20 parts of ABS resin, 10-20 parts of talcum powder, 2-5 parts of toughening agent, 1-3 parts of acidic regulator, 0.3-1.0 part of metal ion complexing agent, 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 thermostable mineral-reinforced PC/ABS resin composition. Compared with the prior art, the resin composition of the invention has excellent mechanical properties and dimensional stability, as well as good thermal stability, and is very suitable for large-size parts such as automobile spoilers, lidar covers, OA equipment, home appliances and other fields.
