The invention relates to the technical field of recycling of an ABS reclaimed material, and particularly relates to a reclaimed ABS flame-retardant modified material and a preparation method thereof. The reclaimed ABS flame-retardant modified material comprises the following substances: an ABS recycling material, a composite flame retardant, a flame-retardant synergist, a composite anti-aging agent, an antioxidant, a composite toughening agent and a coupling agent. The reclaimed ABS flame-retardant modified material prepared through the method disclosed by the invention has high flame-retardant grade as high as V-0 grade, is high in ageing resistance through the addition of the composite anti-aging agent, can be used for enhancing the tensile strength and the bending strength through the addition of the toughening agent, has the advantages of high anti-impact strength, good processing flowability, high glossiness of a finished product, stability in thermal deformation property, high char yield after combustion and no melting dropping and is greatly enhanced in flame retardance without being influenced in mechanical property. The preparation method disclosed by the invention has the advantages of high ABS purity, few impurities and simple preparation process of the obtained ABS recycling material and excellent property and easiness for industrialization realization of reclaimed ABS.
