Title: David A Pippard: Innovator in Corrosion Inhibition Technologies
Introduction
David A Pippard is a notable inventor based in Hampton Hill, GB. He has made significant contributions to the field of corrosion inhibitors, holding a total of 2 patents. His work focuses on developing methods for producing protective coatings that enhance the durability of materials against corrosion.
Latest Patents
Pippard's latest patents include innovative methods for creating corrosion inhibiting particles. One of his patents describes corrosion inhibiting particles that comprise an inorganic oxide, specifically silica or alumina, which are chemically bound to corrosion inhibiting cations such as calcium or zinc. These particles can be prepared by contacting silica or alumina containing hydroxyl groups with an alkaline solution containing the cations at ambient temperature. The resulting particles can be incorporated into protective coatings, such as paints based on epoxy resins, alkyd resins, vinyl resins, or chlorinated rubbers, in amounts up to 80% by weight based on dry film weight. This formulation allows for coatings that contain up to 7.2% by weight of corrosion inhibiting cations. The release of these cations occurs through ion exchange with other cations, such as the alkali metal cations found in seawater, which is a significant advancement over traditional corrosion inhibiting coatings that rely on water solubility.
Another patent by Pippard focuses on corrosion inhibiting particles that consist of an inorganic oxide, particularly alumina, with corrosion inhibiting anions like phosphate, chromate, or benzoate chemically bound to them. These particles are prepared by contacting an oxide containing hydroxyl groups with an acidic solution containing the anions at ambient temperatures. Similar to his previous work, these particles can be incorporated into protective coatings, allowing for coatings with up to 4.0% corrosion inhibiting anions. The release mechanism for these anions also relies on ion exchange with other anions, such as chloride anions from seawater or salt spray.
