Description
- This application claims priority to U.S. Provisional Application No. 60/417,708; filed on Oct. 10, 2002, the disclosure of which is incorporated herein by reference in its entirety.
- The present invention relates to an anti-corrosion composition suitable for use on a variety of substrates. Of particular interest is the use of the composition as a coating for corrosive industrial environments such as smoke stacks, rail cars, hoppers, factory floors, pipe linings, engine rooms and the like.
- Metal substrates and related parts in such industrial environments are subjected to a number of acids and bases due to the variety of compositions that pass through, contact, or are contained in the industrial environment. For example, a rail car may have a solvent such as a highly polar alcohol sitting in the rail car for months or even longer periods of time. Similarly, an acid such as sulphuric acid may be generated due to an industrial process and caused to exit a smokestack on a substantially constant basis. Often, the only way to avoid the corrosive nature of such acids or bases is to completely scrap the article after a period of use. Alternatively, use of the article can be discontinued so that a lengthy cleaning can occur. These alternatives are expensive and can lead to long down times caused by replacement or the discontinued use. It would be desirable to have an alternative that would allow the article to be used for a longer time. Thus, there is a need for an anti-corrosive coating that can withstand a wide variety of acid or base conditions, and can be simply and inexpensively applied to a substrate.
- The anti-corrosion composition of the present invention includes a glass matrix formed by crosslinking a mixture of an amine-functionalized silane and an alkoxy-functionalized siloxane, an epoxy, and optionally and preferably a compatibilizing agent for coupling the epoxy and the alkoxy-functionalized siloxane of the glass matrix. The epoxy can further include a curing agent, preferably an amine. The amine-functionalized silane preferably is compatible with the amine curing agent. The composition, once crosslinked, is an epoxy-modified interpenetrating network of glass and epoxy. The present invention also provides a treated substrate for use in an industrial environment, and includes various metals such as steel, stainless steel, aluminium, magnesium and zinc.
- As discussed above, the anti-corrosion composition comprises a glass matrix formed by crosslinking a mixture of an amine-functionalized silane and an alkoxy-functionalized siloxane, an epoxy, and, optionally, a compatibilizing agent for coupling the epoxy and the alkoxy-functionalized siloxane of the glass matrix. The glass matrix is crosslinked using a titanium or tin catalyst. Suitable catalysts include, without limitation, titanium alkoxides such as titanium methoxide, titanium ethoxide, titanium isopropoxide, titanium propoxide, titanium butoxide, titanium diisopropoxide (bis 2,4-pentanedionate), titanium diisopropoxide bis(ethylacetoacetateo)titanium ethylhexoxide, and organic tin compounds such as dibutyl tin diacetate, dibutyltin dilaurate, dimethyl tin dineodecanoate, dioctyl dilauryl tin, and dibutyl butoxy chlorotin, as well as mixtures thereof. The glass matrix can be formed by using a Sol-Gel process such as described in U.S. Pat. No. 6,313,193, the disclosure of which is incorporated herein by reference in its entirety. Other methods of forming the matrix will be within the skill of one in the art. The glass matrix provides good adhesion to the surface being coated, as well as toughness, crack resistance, durability, abrasion resistance, heat resistance and stability in the particular environment.
- The matrix formulation may also include fillers (e.g., fumed silica, mica, kaolin, bentonite, talc), zinc oxides, zinc phosphates, iron oxides, cellulose, pigments, corrosion inhibitors, UV light stabilizers, thixotropic agents, epoxy modifiers, polytetrafluoroethylene powder, ultra high molecular weight polyethylene powder, high, medium and low molecular weight polyethylene powder, or other additives, as will be readily apparent to those skilled in the art.
- Suitable amino-functionalized silanes include 3-aminopropyltriethoxy silane, 3-aminopropyldimethylethoxy silane, 3-aminopropyl methyldiethoxy silane and 3-aminopropyltrimethoxy silane. Suitable alkoxy-functionalized siloxanes include polydiethoxysiloxane, tetraethoxysilane, tetramethoxysilane and polydimethoxy siloxane. Inasmuch as these compounds form silicates through a water condensation reaction, the inherent moisture of metal being treated can be used to facilitate the reaction without having to remove the moisture. Thus substrates such as stem pipes can be easily and inexpensively treated by using the moisture on the outside of the pipe to facilitate the crosslinking reaction.
- Epoxy compounds are well known and are described in, for example, U.S. Pat. Nos. 2,467,171; 2,615,007; 2,716,123; 3,030,336; and 3,053,855 which are incorporated herein by reference in their entirety.
