摘要：
Provided is a method for producing a raw material of grease, including: preparing a first thickener raw material; a second thickener raw material; a first lubricating oil; a second lubricating oil; a first solvent that has a boiling point lower than those of the first lubricating oil and the second lubricating oil, dissolves the first lubricating oil, and does not dissolve a produced thickener; and a second solvent that has a boiling point lower than those of the first lubricating oil and the second lubricating oil, dissolves the second lubricating oil, and does not dissolve the produced thickener; dissolving the first lubricating oil in the first solvent, and dissolving or dispersing the first thickener raw material in the first solvent to obtain a first mixed solution; dissolving the second lubricating oil in the second solvent, and dissolving or dispersing the second thickener raw material in the second solvent to obtain a second mixed solution; and mixing the first mixed solution and the second mixed solution, and reacting the first thickener raw material and the second thickener raw material to produce a thickener.
