Abstract

A lubricant composition including: tungsten disulfide having a particle size of 4 to 160 nm; an alkali metal borate; a borate ester; and a base oil.

Claims

1. A lubricant composition comprising:

tungsten disulfide having a particle size of 4 to 160 nanometers;

an alkali metal borate;

a borate ester; and

a base oil.

2. The lubricant composition of claim 1, wherein the tungsten disulfide has an average particle size of 10 to 1000 nm.

3. The lubricant composition of claim 1, wherein the tungsten disulfide is inorganic fullerene tungsten disulfide.

4. The lubricant composition of claim 1, wherein the tungsten disulfide is contained in an amount of 0.01 to 3 weight percent, based on a total weight of the lubricant composition.

5. The lubricant composition of claim 1, wherein the alkali metal borate comprises sodium borate, potassium borate, or a combination thereof.

6. The lubricant composition of claim 5, wherein the alkali metal borate is potassium borate.

7. The lubricant composition of claim 6, wherein the potassium borate is KBO₂, KB₅O₈.4H₂O, KBO₂.½

H₂O, K₂B₄O₇.4H₂O, K₂B₄O₇.8H₂O, KB₃O₅.3H₂O, or a combination thereof.

8. The lubricant composition of claim 5, wherein the alkali metal borate is contained in an amount of 0.01 to 3 weight percent, based on a total weight of the lubricant composition.

9. The lubricant composition of claim 1, wherein the borate ester is a reaction product of a fatty oil, a dialkanolamine, and a boric acid.

10. The lubricant composition of claim 1, wherein the borate ester is according to Formula 1:

11. The lubricant composition of claim 10, wherein the borate ester is triisopropanolamine borate.

12. The lubricant composition of claim 1, wherein the borate ester is contained in an amount of 0.0001 to 20 weight percent, based on a total weight of the lubricant composition.

13. The lubricant composition of claim 1, wherein the base oil comprises a polyalphaolefin.

14. The lubricant composition of claim 1, wherein

the tungsten disulfide is inorganic fullerene tungsten disulfide,

the alkali metal borate is potassium borate,

the borate ester is a reaction product of a fatty oil, a dialkanolamine, and a boric acid, and

the base oil is a polyalphaolefin.

15. An applicator having the lubricant composition of claim 1 disposed on the applicator.

16. The applicator of claim 15, wherein the applicator is effective to clean a bore of a firearm.

21. The lubricant composition of claim 1, wherein a content of the base oil is 5 to 99.9 weight percent, based on a total weight of the lubricant composition.

17. firearm cleaning system comprising:

a container;

an applicator disposed in the container; and

a lubricant composition disposed on the applicator,

wherein the lubricant composition comprises

tungsten disulfide comprising tungsten disulfide particles having a diameter of 4 to 160 nanometers;

an alkali metal borate;

a borate ester; and

a base oil.

18. The firearm cleaning system of claim 17, wherein the container is a tear-open pouch.

19. The firearm cleaning system of claim 18, wherein the tear-open pouch comprises a thermoplastic film.

20. A method of manufacturing a lubricant composition, the method comprising:

contacting

tungsten disulfide having a particle size of 4 to 160 nanometers,

an alkali metal borate,

a borate ester, and

a base oil under conditions effective to disperse the tungsten disulfide, the alkali metal borate, and the borate ester in the base oil to manufacture the lubricant composition.
