    • The present invention relates to the field of metal detergent, especially to a metal detergent and a preparation method thereof and a lubricant oil containing the metal detergent. The metal detergent provided by the present application is sulfurized calcium alkyl phenolate, the method for preparing the metal detergent includes the following steps: a) mixing alkyl phenol, a calcium source and base oil to obtain a mixed solution; b) mixing the mixed solution, ethylene glycol and a sulfur source to carry out sulfurization reaction to obtain a sulfurization reaction solution; c) implementing carbonation reaction between the sulfurization reaction solution and CO 2 to obtain a carbonation reaction solution; and d) extracting the carbonation reaction solution with a solvent, upon refining, to obtain sulfurized calcium alkyl phenolate; wherein the solvent includes solvent oil, water and oxygenous derivative of hydrocarbon. Experimental results show that the content of free alkyl phenol is below 1.5 wt% in the sulfurized calcium alkyl phenolate prepared using the preparation method provided by the present application.
