The invention relates to the technical field of recycling of HIPS regenerated materials, and particularly relates to a regenerated HIPS environmental-friendly modified material and a preparation method thereof. The regenerated HIPS environmental-friendly modified material comprises the following substances in parts by weight: 100 parts of HIPS recovered materials, 3-6 parts of toughening agents, 15-20 parts of flame retardants, 1-2 parts of flame-retardant synergists, 10-12 parts of anti-impact modifying agents, 1-2 parts of antioxidants, 1-4 parts of coupling agents, 2-5 parts of lubricating agents and 2-5 parts of stabilizing agents, wherein the flame retardants are formed by mixing a compound flame retardant of ammonium polyphosphate, magnesium hydroxide and boric acid with montmorillonite-hexadecyl trimethyl ammonium bromide. The regenerated HIPS has the advantages of low toxicity, low smoke and no corrosion and is favorable to the flame retardance of HIPS. The regenerated HIPS environmental-friendly modified material disclosed by the invention is high in mechanical property, low in cost, capable of effectively saving the material cost, environmental-friendly, economic and effective. The preparation method disclosed by the invention has the advantages of high HIPS purity and few impurities of an obtained HIPS recovered material, simple preparation process and easiness for industrialization realization.
