Micro-encapsulated, improved vapor corrosion inhibitor

Abstract

The current invention relates to a micro-encapsulated, volatile vapor corrosion inhibitor (VCI), and method for the use of same. More particularly, it relates to a fluid composition, and microencapsulation of the fluid composition, that inhibits corrosion and tarnishing and that may be relatively non-toxic. The VCI is intended to be employed in varying concentrations depending on the intended application and deployed via microcapsules. The microcapsules may be adapted to release the VCI over time, or all at once. To effect this, the microcapsules may be adapted to be breached at varying times or at the same time. By adapting the microcapsules, or the method of breaching the microcapsules, the rate at which the VCI is released may be controlled.

Description

[0001]This application is based upon and claims priority from U.S. Provisional applications, Ser. Nos. 62 / 015,127 and 62 / 016,984, which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The current invention relates to a micro-encapsulted, volatile vapor corrosion inhibitor (VCI), and method for the use of same.

Background Information[0005]Corrosion affects metal (as used herein, “metal” refers to both pure metals and metal alloys) adversely and is a serious problem for both public and private sectors. Corrosion can affect the usefulness of an object and cause the object to need to be repaired or replaced. Either consequence affects the user's time and cost. Consequently, there have been numerous attempts to find ways to combat corrosion. Two of the...

Benefits of technology

[0019]It is also anticipated that the microcapsules could be adapted to release the VCI over time, or all at once. To effect this, the microcapsules may be adapted to be breached at varying times. By adapting the microcapsules, or the method of breaching the microcapsules, the rate at which the VCI is released may be controlled.

Problems solved by technology

Corrosion affects metal (as used herein, “metal” refers to both pure metals and metal alloys) adversely and is a serious problem for both public and private sectors.

Corrosion can affect the usefulness of an object and cause the object to need to be repaired or replaced.

Either consequence affects the user's time and cost.

However, as chemical reactions continue to occur with oxygen, the corrosion inhibitor will eventually be depleted and the inhibition will be terminated.

Or, in the case of oils that create a barrier, degrade and become ineffective over time.

Thus, corrosion inhibitors tend to be temporary in nature.
