Insulation articles including corrosion inhibitors and methods of producing the same

Abstract

Unique insulation articles including corrosion inhibitors and methods of producing the same are disclosed. One exemplary embodiment is an article of manufacture comprising an insulation mat comprising a cured combination of a plurality of randomly oriented fibers and a binder, the insulation mat extending between a first surface and a second surface, a veil attached to the first surface, the veil structured to inhibit physical movement of the cured combination through the veil, a metal sheet attached to the second surface by a water-containing adhesive contacting the metal sheet and the second surface, and a corrosion inhibitor composition deposited on the cured combination of the insulation mat, the corrosion inhibitor composition being effective to modify toward neutral a pH of the cured combination in contact with water from the water-containing adhesive.

What is claimed is: 
     
         1 - 34 . (canceled) 
     
     
         35 . A method comprising:
 providing an insulation mat comprising a cured combination of a plurality of randomly oriented fibers and a binder and a veil attached to a first surface of the cured combination and effective to inhibit physical movement of the cured combination through the veil;   applying a corrosion inhibitor composition to the cured combination of the insulation mat;   attaching a metal sheet to a second surface of the cured combination with a water-containing adhesive contacting the metal sheet and the second surface; and   contacting the veil with a second metal sheet;   wherein the corrosion inhibitor composition is effective to inhibit a reaction of water from the water-containing adhesive, the cured combination and the second metal sheet.   
     
     
         36 . The method of  claim 35 , wherein the corrosion inhibitor composition is effective to modify toward neutral a pH of the cured combination in contact with water from the water-containing adhesive. 
     
     
         37 . The method of  claim 35 , wherein the corrosion inhibitor composition is effective to passivate a surface of the second metal sheet. 
     
     
         38 . The method of  claim 35 , wherein the act of providing an insulation mat includes curing the binder in combination the plurality of randomly oriented fibers with the veil contacting the first surface effective to provide the cured combination and to attach the veil to the first surface. 
     
     
         39 . The method of  claim 35 , wherein the act of applying comprises applying the corrosion inhibitor composition to a second surface of the cured combination of the insulation mat, the second surface being opposite from the first surface. 
     
     
         40 . The method of  claim 39 , wherein the corrosion inhibitor composition is applied to the second surface by spraying one of an aqueous solution including the corrosion inhibitor composition and an aqueous slurry including the corrosion inhibitor composition. 
     
     
         41 . A method comprising:
 forming an insulation mat comprising a combination of a plurality of randomly oriented fibers and a binder, the insulation mat extending between a first side and a second side;   applying a veil to the first side of the insulation mat;   curing the insulation mat and the veil effective to bind the plurality of randomly oriented fibers and to bind the veil to the first side; and   applying a corrosion inhibitor composition to the second side of the insulation mat;   wherein the cured combination has one of an acidic pH and an alkaline pH when immersed in deionized water, and the corrosion inhibitor composition has the other of the acidic pH and the alkaline pH when immersed in deionized water.   
     
     
         42 . The method of  claim 41 , further comprising:
 attaching a first metal sheet to the second side of the insulation mat with a water-containing adhesive contacting the metal sheet and the second surface; and   contacting the veil with a surface of a second metal sheet;   wherein the corrosion inhibitor composition is effective to inhibit a reaction of water from the water-containing adhesive, the cured combination and the second metal sheet.   
     
     
         43 . The method of  claim 42 , wherein the surface of the second metal sheet contacting the veil is galvanized. 
     
     
         44 . The method of  claim 42 , wherein the corrosion inhibitor composition modifies toward neutral a pH of the cured combination in contact with water from the water-containing adhesive. 
     
     
         45 . The method of  claim 42 , wherein the corrosion inhibitor passivates the surface of the second metal sheet. 
     
     
         46 . The method of  claim 42 , wherein the binder comprises one of an acrylic binder, a polyester-type binder, a binder which includes at least one reaction product from a Maillard reaction, and a combination thereof.
