Corrosion inhibitors, methods of production and uses thereof
View Patent ↗Compositions for actively inhibiting corrosion are described herein that include at least one active corrosion inhibitor compound, and at least one conventional corrosion inhibitor compound. In addition, methods for producing a composition that actively reduces corrosion are described herein and include providing at least one active corrosion inhibitor, providing at least one conventional corrosion inhibitor compound or corrosion protection compound, and blending the at least one active corrosion inhibitor and the at least one conventional corrosion inhibitor compound or corrosion protection compound to form the composition. In addition, a composition for actively inhibiting corrosion is described herein that includes at least one active corrosion inhibitor compound, wherein the at least one active corrosion inhibitor compound comprises a derivative or salt of a thio-, thia- or dithiocarbarnic acid, or a combination thereof and at least one conventional corrosion inhibitor compound. Coatings and composite materials containing these active corrosion inhibitor compounds and compositions are also described.
1. A composition for actively inhibiting corrosion, comprising:
at least one active corrosion inhibitor compound, wherein the at least one active corrosion inhibitor compound comprises salts of dimethyldithiocarbamate (DMDTC) synthesized with a long chain aliphatic ammonium or an amine compound as a cation; and
at least one conventional corrosion inhibitor compound, wherein the at least one conventional corrosion inhibitor compound comprises calcium dinonyl naphthalene sulfonate.
2. The composition of claim 1 , comprising at least one solvent.
3. The composition of claim 1 , wherein the at least one active corrosion inhibitor is present in an amount less than about 20 weight percent.
4. The composition of claim 1 , wherein the at least one active corrosion inhibitor is present in an amount less than about 5 weight percent.
5. A coating material comprising the composition of claim 1 .
6. A coating material comprising the composition of claim 2 .
7. The coating material of one of claims 5 or 6 , wherein the material is paint, primer or a combination thereof.
8. A method of producing a composition that actively reduces corrosion, comprising:
providing at least one active corrosion inhibitor, wherein the at least one active corrosion inhibitor compound comprises salts of dimethyldithiocarbamate (DMDTC) synthesized with a long chain aliphatic ammonium or an amine compound as a cation,
providing at least one conventional corrosion inhibitor compound or corrosion protection compound, wherein the at least one conventional corrosion inhibitor compound comprises calcium dinonyl naphthalene sulfonate, and
blending the at least one active corrosion inhibitor and the at least one conventional corrosion inhibitor compound or corrosion protection compound to form the composition.
