description The invention discloses rubber powder based thermoplastic dynamic vulcanized rubber (named TPRV) and a preparation method thereof, and relates to the technical field of waste rubber recycling. The invention discloses a formula for continuously producing rubber powder-based thermoplastic dynamic vulcanized rubber by utilizing a twin-screw one-step method. The formula comprises the following components: waste rubber powder, polyolefin resin, an environment-friendly plasticizer, maleic anhydride grafted polyolefin, an activating agent, a cross-linking agent and white mineral oil. The invention further discloses technological methods and parameters such as raw material ratio, raw material blending, feeding mode, temperature partition setting and screw rotating speed. According to the invention, the current situation of utilization of waste rubber mainly based on regeneration is broken, the vicious circle of vulcanization, regeneration and vulcanization is cut off, the efficient, green and recyclable utilization o
