The invention relates to a method for producing environment-friendly rubber filling oil, which comprises the following steps: performing extraction through back flow and sufficient contact in an extraction tower by using the specific gravity difference of raw oil and a solvent; dissolving polycyclic aromatic hydrocarbon in the raw oil into the solvent, and depositing the polycyclic aromatic hydrocarbon to the bottom area of the tower automatically; raising the raw oil after the extraction to the top of the tower automatically; performing solvent recovery through a steam stripping process; andremoving the carried solvent to obtain the environment-friendly rubber filling oil. The method has the advantages that the environmental protection of an oil product meets European Union requirements, the oil product has good compatibility with rubber, and the adopted solvent recovery process has the advantages of high solvent recovery rate, easily achieved conditions and the like.
