Claims
- 1. A corrosion-inhibiting composition which comprises:
- (a) about 5 to 80% by weight of a rust-inhibitive, grease-like concentrate comprising a thioxotropic inorganic/organic complex stably dispersed in an essentially inert liquid oily phase in an amount not to exceed 4 parts, per part of said complex, of said essentially inert liquid oily phase, said inorganic/organic complex comprising an over-based alkaline earth organic sulfonate salt, whereby the crystalline structure of the inorganic portion of said complex is platelet and film-forming in character;

C.;
- (c) about 0.03 to 0.6% by weight metal provided by a first metal drier selected from the group consisting of copper carboxylate compounds, rare earth carboxylate compounds, and mixtures thereof;
- (d) about 0.1 to 2.2% by weight metal provided by a second metal drier selected from the group consisting of zinc carboxylate compounds;
- (e) about 10 to 90% by weight organic solvent; and
- (f) about 2 to 15% petrolatum.
- 2. The composition of claim 1 which further comprises up to 5% by weight polyisobutylene.
- 3. The composition of claim 1 wherein the first metal drier comprises a copper carboxylate compound, and the composition further comprises a third metal drier comprising a rare earth carboxylate compound providing a rare earth metal concentration of about 0.06 to 0.3% by weight of the composition.
- 4. The composition of claim 3 wherein the third metal drier comprises a lanthanum or cerium carboxylate compound.
- 5. The corrosion-inhibiting composition of claim 1 wherein the first metal drier consists essentially of neutralized copper organic acid compounds.
- 6. The corrosion-inhibiting composition of claim 5 wherein the second metal drier consists essentially of neutralized zinc organic acid compounds.
- 7. The corrosion-inhibiting composition of claim 6 wherein the drying oil comprises tung oil.
- 8. The corrosion-inhibiting composition of claim 7 wherein the over-based alkaline earth organic sulfonate salt comprises an over-based calcium sulfonate compound.
- 9. A corrosion-inhibiting composition which consists essentially of about 20 to 40% over-based calcium sulfonate, about 10 to 20% tung oil, about 30 to 60% organic solvent, about 3 to 8% petrolatum, about 0.1 to 0.6% copper provided by copper carboxylate compounds, and about 0.2 to 1.1% zinc provided by zinc carboxylate compounds.
- 10. A corrosion-inhibiting composition which consists essentially of about 20 to 40% over-based calcium sulfonate, about 10 to 20% tung oil, about 30 to 60% organic solvent, about 3 to 8% petrolatum, about 0.1 to 0.6% copper provided by copper carboxylate compounds, about 0.2 to 1.1% zinc provided by zinc carboxylate compounds, and up to about 5% polyisobutylene.
- 11. A corrosion-inhibiting composition which consists essentially of about 20 to 40% over-based calcium sulfonate, about 10 to 20% tung oil, about 30 to 60% organic solvent, about 3 to 8% petrolatum, about 0.1 to 0.6% copper provided by copper carboxylate compounds, about 0.2 to 1.1% zinc provided by zinc carboxylate compounds, and about 0.06 to 0.3% rare earth metals provided by rare earth carboxylate compounds.
- 12. A corrosion-inhibiting composition which consists essentially of about 20 to 40% over-based calcium sulfonate, about 10 to 20% tung oil, about 30 to 60% organic solvent, about 3 to 8% petrolatum, about 0.1 to 0.6% copper provided by copper carboxylate compounds, about 0.2 to 1.1% zinc provided by zinc carboxylate compounds, about 0.06 to 0.3% rare earth metals provided by rare earth carboxylate compounds, and up to about 5% polyisobutylene.
