Abstract
A lubricant made by a method of modifying fluid suspended metal sulfide particles that does not require use of hazardous additives. The base oil is derived from a proprietary ester lubricant. The formulation process includes a centrifugation step to remove non-colloidal metal sulfide particles. These non-colloidal particles may be collected and turned into colloidal particles for use in future batches of lubricant.
Claims20
A lubricant comprising:
- a colloidal suspension of a base oil and molybdenum disulfide particles having an average particle size between 10 and 5500 nanometers wherein said molybdenum disulfide particles are dispersed in said base oil by applying electrical and magnetic fields to said colloidal suspension while mixing, wherein the electric field is applied using a voltage greater than or equal to about 3 volts.
A method of making a lubricant comprising the steps of:
- (a) agitating molybdenum disulfide with a base oil in a reactor in the presence of a magnetic field stronger than the strength of the earth's magnetic field, wherein the base oil is selected from the group consisting of vegetable oil, vegetable oil-derived methyl ester oil, and combination thereof;
- (b) applying, simultaneously with step (a) if desired, an electrical field to the reactor created using a voltage greater than or equal to about 3 volts, wherein the molybdenum disulfide is in the form of particles having an average particle size of about 10 nanometers to about 5500 nanometers after becoming part of the lubricant composition.
