The invention provides a processing technology of a bromine-containing antiflaming acrylonitrile butadiene styrene (ABS) plastic with a stable color. The technology comprises the following main steps: step 1, processing heat-resisting tetrabromobisphenol A: in a high-speed mixing machine, adding and mixing the following components in percentage by weight: 57-61% of tetrabromobisphenol A, 33-35% of chlorinated polyethylene (GPE), 2.5-3.5% of stabilizer Ca-Zn and 2.5-3.5% of organic tin stabilizer, putting the mixed material in a two-roller open mill for mixing until the mixed material is of a flaky shape, then taking out, and smashing the sheets into particles after cooling; and step 2, in the high-speed mixing machine, mixing the following components in percentage by weight: 5-7% of decabromodiphenylethane, 4.5-5.5% of antimonous oxide Sb2O3, 75-77% of ABS, 0.5% of auxiliary and 11-13% of heat-resisting tetrabromobisphenol A prepared in the step 1, feeding the mixture in a two-screw extruder for plastifying e
