The invention provides a preparation method of high-oil-filled liquid reclaimed rubber, belonging to the field of reclaimed rubber production. The invention mixes waste rubber powder with part of softener and preheats the mixture; feeds the mixed and preheated raw materials into a twin-screw or multi-screw extruder for heating and preliminary de-crosslinking; feeds the preliminarily de-crosslinked raw materials into a parallel co-rotating twin-screw extruder, adds the remaining softener in batches through multiple feeding ports on the barrel, and extrudes to obtain high-oil-filled liquid reclaimed rubber. Compared with traditional reclaimed rubber, the product of the invention has better processability, smoother surface, low-carbon and environment-friendly production process, and greatly improves the added value of waste rubber resource utilization.
