The present invention relates to a low-gloss heat-resistant ABS resin composition and its preparation method. The low-gloss heat-resistant ABS resin composition includes following components by weight: 100 parts of acrylonitrile-butadiene-styrene (ABS) resin, 5-30 parts of heat-resistant agent, 1-5 parts of matte masterbatch D, 0.2-1.0 parts of light stabilizer, and 0.5-2.0 parts of other additives. The preparation method includes steps of: stirring and fully mixing the above-mentioned raw materials in a high-speed mixer, and then feeding the raw materials into a twin-screw extruder through a metering device; melting and compounding the materials under the conveying, shearing and mixing of the screws, and then extruding, pulling, cooling and granulating, and finally obtaining the low-gloss heat-resistant ABS resin composition. The resin composition provided by the present invention not only has excellent mechanical properties, but also has an ultra-low gloss; therefore, it is very suitable for use in the field of automotive interior parts.
