The invention discloses a micro-nano reclaimed rubber-based thermoplastic elastomer and a preparation method thereof. The micro-nano reclaimed rubber-based thermoplastic elastomer comprises the following raw material components in parts by weight: 60-80 parts of low-Mooney micro-aerobic reclaimed rubber; 20-40 parts of resin; 4-8 parts of a vulcanization system; 2-10 parts of a compatibilizer; 2-8 parts of a softening plasticizer; and 1-6 parts of an anti-aging agent. According to the preparation method provided by the invention, a large amount of low-cost reclaimed rubber can be used, the preparation is simple, high-valued recovery of the waste tire rubber is realized, the reclaimed rubber is dispersed in the resin in a micro-nano degree, the interfacial compatibility between two phases is excellent, the obtained product is good in processability and excellent in physical and mechanical properties, the sol content of the micro-nano reclaimed rubber is high, the gel is evolved from dozens of microns to micro-
