Raw material of grease, method for producing raw material of grease, method for producing grease, and grease

A method for producing a raw material of grease, comprising:

• preparing a first thickener raw material;
• a second thickener raw material;
• a first lubricating oil;
• a first solvent that has a boiling point lower than that of the first 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 that of the first lubricating oil and does not dissolve a 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 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,
• removing the first solvent from the first mixed solution to which the first lubricating oil has been added;
• and
• pulverizing the first mixed solution from which the first solvent has been removed to obtain a raw material of grease being a thickener powder containing, a thickener and the first lubricating oil.

A method for producing a raw material of grease comprising:

• preparing a synthesized thickener;
• a first lubricating oil;
• and
• a first solvent that has a boiling point lower than that of the first lubricating oil, dissolves the first lubricating oil, and does not dissolve the thickener;
• and
• dissolving the first lubricating oil in the first solvent to obtain a first solution, and impregnating the thickener with the obtained first solution,
• removing the first solvent from the thickener impregnated with the first solution;
• and
• pulverizing the thickener from which the first solvent has been removed, to obtain a raw material of grease being a thickener powder containing, a thickener and the first lubricating oil.
