JP4388911B2 - New multipurpose rust inhibitor and penetrant - Google Patents

Description

  The present invention relates to a multipurpose rust inhibitor and penetrant for industrial and household applications.

  In industrial and home environments, general lubricants are often needed for a variety of purposes, such as loosening screws, reducing stagnation in hinges or other moving objects, and removing moisture from electrical appliances. The In the present invention, such a lubricant is defined as a "light work lubricant", which is applied to a metal surface or a movable part by a method such as spraying to reduce corrosion and temporarily lubricate the part. . Such a lubricant is effective in reducing corrosion by removing moisture or moisture from the surface of the movable part.

  It is desirable that such a light work lubricant has a surface tension capable of efficiently covering the surface of the movable part. In order for the lubricant to penetrate between the narrow moving parts and loosen or lubricate the parts, the viscosity of the lubricant needs to be relatively low. In many cases, such lubricants are mainly composed of a relatively volatile oily diluent.

  Unfortunately, conventional light work lubricants that are effective in preventing corrosion, wear, and stagnation of metal moving parts often required application to the moving parts. Volatility of the lubricant is desirable when a relatively low oil portion is required, but is not desirable when the lubricant needs to continue to work for a long time.

  Despite the wide variety of light work lubricants on the market, there is always a need for improved multipurpose light work lubricants.

  In view of the foregoing, one disclosed example of the present invention relates to penetrants and coating concentrate compositions for metals having improved corrosion protection properties. Such a composition comprises about 2 wt% or more and about 5 wt% or less of an ashless acidic rust inhibitor, about 25 wt% or more and about 50 wt% or less of a neutral sulfonic acid alkaline earth metal salt corrosion inhibitor, about 25 wt%. More than about 50% by weight or less of phosphorus-based corrosion inhibitor and process oil are included.

  One of the other disclosed examples relates to a method for preventing corrosion of a metal surface by applying a corrosion inhibiting composition to the metal surface. Such a composition comprises about 2 wt% or more and about 5 wt% or less of an ashless acidic rust inhibitor, about 25 wt% or more and about 50 wt% or less of a neutral sulfonic acid alkaline earth metal salt corrosion inhibitor, about 25 wt%. More than about 50% by weight or less of phosphorus-based corrosion inhibitor and process oil are included.

  Yet another disclosed example relates to a method of lubricating moving parts and protecting them from corrosion. Such a method includes an ashless acidic rust inhibitor of about 2 wt% to about 5 wt%, a neutral sulfonic acid alkaline earth metal salt corrosion inhibitor of about 25 wt% to about 50 wt%, about 25 wt% or more. Including application to a moving part of a corrosion inhibiting composition comprising about 50 wt% or less of a phosphorus based corrosion inhibitor and a process oil.

  A feature of the present invention is the improved anti-corrosion ability of the composition. Another feature of the composition according to the invention resides in a composition having improved lubricity over time. A further feature of the composition according to the invention is that it can be mixed with a light or medium weight diluent oil and is therefore flexible for use in a wide range of applications.

DETAILED DESCRIPTION OF THE INVENTION The composition according to the present invention is characterized by containing a plurality of corrosion prevention and rust prevention components, unlike other ordinary products. Corrosion-preventing components and rust-preventing components complement each other and exhibit excellent anti-corrosion and anti-wear properties. Another feature of the present invention is that the formulation can be easily changed according to the application. The composition can be used as a concentrate or mixed with a diluent to obtain a composition having the desired viscosity. Other compositions according to the present invention contain a tackifier component that improves the ability to remain on the treated surface for an extended period of time.

  For purposes of the present invention, “light work” excludes only engines, gear trains, transmission lubricants, and high speed heavy duty lubricants. All other lubricants are handled as “light work”.
