description The invention discloses a high-heat-resistance and high-fluidity modified polylactic acid material and a preparation method thereof, and belongs to the technical field of high polymer materials. According to the high-heat-resistance and high-fluidity modified polylactic acid material disclosed by the invention, hydroxyethyl ethylene bisstearamide, zinc phenylphosphonate and styrene-methyl methacrylate are adopted as modifiers, and nucleation sites in a polylactic acid crystallization process are increased by utilizing the modifiers, so that the heat resistance of the polylactic acid material is improved; by adopting the modifier, the crystallization rate of the PLA can be effectively improved, enough crystallinity is formed in the cooling process of the PLA, according to related experimental results, by adopting the modifier and combining other components, the thermal deformation temperature of the PLA can be increased to 140 DEG C or above from 60 DEG C, meanwhile, the needed adding amount of the modifier is
