Corrosion inhibiting mixture

Abstract

A corrosion inhibiting mixture is disclosed comprising a volatile corrosion inhibitor and a binding matrix, wherein the binding matrix comprises a resin selected from the group of a plastisol, a urethane and an epoxy. The mixture is liquid near ambient temperature and irreversibly cured when heated in a temperature range of about 20° C. to 150° C.

1 . A corrosion inhibiting mixture comprising, in combination:
 a volatile corrosion inhibitor; and   a binding matrix, wherein the binding matrix comprises a resin selected from the group of a plastisol, a urethane and an epoxy;   wherein the mixture is liquid near ambient temperature and irreversibly cured when heated in a temperature range of about 20° C. to 150° C.   
     
     
         2 . The corrosion inhibiting mixture of  claim 1  wherein the volatile corrosion inhibitor is selected from the group consisting of at least one of benzoic acid, a salt of benzoic acid, an inorganic nitrite salt, an amine nitrite salt, a carboxylic acid, a salt of a carboxylic acid, a salt of an amine, an azole, a salt of an azole, a salt of molybdenum and an amine molybdates. 
     
     
         3 . The corrosion inhibiting mixture of  claim 1  wherein the volatile corrosion inhibitor comprises about 10-50% by weight of the mixture, and the binding matrix comprises about 90-50% by weight of the mixture. 
     
     
         4 . The corrosion inhibiting mixture of  claim 1  wherein the binding matrix comprises a plastisol formed from a plasticizer and one of a PVC resin and an acrylic co-polymer. 
     
     
         5 . The corrosion inhibiting mixture of  claim 4  wherein the plastisol is a PVC resin which comprises about 20-60% by weight of the mixture, and the plasticizer comprises about 15-35% by weight of the mixture. 
     
     
         6 . The corrosion inhibiting mixture of  claim 4  wherein the plastisol is an acrylic copolymer and the resin further comprises a cross linking resin. 
     
     
         7 . The corrosion inhibiting mixture of  claim 1  further comprising about 1-10% by weight of a viscosity control agent. 
     
     
         8 . The corrosion inhibiting mixture of  claim 1  further comprising about 1-30% by weight of a mineral filler. 
     
     
         9 . The corrosion inhibiting mixture of  claim 1  wherein the binding matrix comprises about 3-10% by weight of a hardener and the resin comprises about 50-85% by weight of one of a urethane and an epoxy.
