Method for Anti-Corrosion Treatment

Abstract

A method provides an adhesive strip for anti-corrosion treatment of metal surfaces. The adhesive strip has a layer of olefin polymer and a crosslinker and is applied onto a metal surface. The strip is heated such that the layer melts, thereby forming an anti-corrosion layer for the metal surface.

1 . A method for the corrosion control treatment of metal surfaces, the method comprises:
 applying in that an adhesive tape to a metal surface, wherein the adhesive tape has a layer of an olefin polymer and a crosslinker; and   heating the adhesive tape such that the layer melts to from corrosion control layer.   
     
     
         2 . The method according to  claim 1 , wherein
 the olefin polymer is a copolymer or terpolymer of ethylene and a vinyl ester.   
     
     
         3 . The method according to  claim 1 , wherein
 the olefin polymer is a copolymer or terpolymer of ethylene and acrylic or methacrylic ester.   
     
     
         4 . The method according to  claim 1 , wherein
 the olefin polymer has no crystallite melting point.   
     
     
         5 . The method according to  claim 1 , wherein
 the crosslinker is a peroxide.   
     
     
         6 . The method according to  claim 1 , wherein the layer has a thickness between 50 μm and 750 μm. 
     
     
         7 . The method according to  claim 1 , wherein a surface of the corrosion control layer has been modified to ensure sufficient adhesion to a subsequently applied plastisol layer or paint layer. 
     
     
         8 . The method according to  claim 1 , wherein the layer melts at a temperature of not less than 90° C. 
     
     
         9 . The method according to  claim 1 , wherein the layer is a pressure-sensitively adhesive. 
     
     
         10 . The method according to  claim 1 , wherein pressure-sensitive adhesive is located between the layer and the metal surface. 
     
     
         11 . (canceled) 
     
     
         12 . The method of  claim 1 , wherein the olefin polymer is a copolymer or terpolymer of ethylene and vinyl acetate. 
     
     
         13 . The method according to  claim 3 , wherein the olefin polymer is a copolymer or terpolymer of ethylene and methyl, ethyl or butyl acrylate. 
     
     
         14 . The method according to  claim 1 , wherein the layer has a thickness that is between 100 μm and 600 μm. 
     
     
         15 . The method according to  claim 1 , wherein the layer has a thickness that is between 200 μm and 400 μm. 
     
     
         16 . The method according to  claim 1 , wherein the olefin polymer has a crystallite melting point of below 105° C. 
     
     
         17 . The method according to  claim 1 , wherein the layer melts at a temperature of not less than 110° C. 
     
     
         18 . The method according to  claim 1 , wherein the layer melts at a temperature of not less than 130° C.
