The invention discloses high aromatic environment-friendly rubber oil and a preparation method thereof. The method comprises the following steps: (1) carrying out hydrotreatment on diasphalted oil to obtain hydrotreating oil; (2) carrying out solvent refining on the hydrotreating oil in a first solvent extraction tower, obtaining first raffinate from the top of the first solvent extraction tower, obtaining first raffinate oil by recovering the solvent, obtaining first displacing liquid from the bottom of the first solvent extraction tower, and obtaining first extracted oil by recovering the solvent; (3) carrying out solvent refining on the first raffinate oil in a second solvent extraction tower, obtaining second raffinate from the top of the second solvent extraction tower, obtaining second raffinate oil by recovering the solvent, obtaining second displacing liquid from the bottom of the second solvent extraction tower, and obtaining the rubber oil by recovering the solvent. The environment-friendly rubber oil provided by the invention is high in aromatic content; the mass percent of aromatic carbon can be up to 20-33%. Therefore, the high aromatic environment-friendly rubber oil is good in compatibility with rubber, and excellent in processability, and can provide excellent performances such as good wet sliding resistance and the like to a tire when being used in a tire manufacturing process.
