  • Patent number: 9738793
    Abstract: The present invention relates to the application of polymeric resins and TiO2 doped with polymeric resins as coatings for external metal surfaces for industrial use, mainly by selecting the following metals: stainless steel, carbon steel and copper. Focuses specifically on the synthesis of a polymeric resin waterborne corrosion consisting of nano-structured polymer particles formed with two or more acrylic monomers, vinyl or styrenic a functionalizing agent and a crosslinking agent from 1.0 to 20% wt. each. Doping addition is made of the same polymeric resins, which are incorporated in nanotubes of titanium dioxide in concentrations ranging from 50 to 10,000 ppm. The polymeric resin is water based corrosion synthesized by emulsion polymerization techniques and is during the synthesis process is introduced nanotube loading of titanium dioxide (which are synthesized according to U.S. Pat. No. 7,645,439 B2), which allowing the dispersion in the polymer matrix.

Focuses specifically on the synthesis of a polymeric resin waterborne corrosion consisting of nano-structured polymer particles formed with two or more acrylic monomers, vinyl or styrenic a functionalizing agent and a crosslinking agent from 1.0 to 20% w each. Doping addition is made of the same polymeric resins, which are incorporated in nanotubes of titanium dioxide in concentrations ranging from 50 to 10,000 ppm. The polymeric resin is water based corrosion synthesized by emulsion polymerization techniques and is during the synthesis process is introduced nanotube loading of titanium dioxide, which allowing the dispersion in the polymer matrix. Polymer dispersions obtained in this way are used as anti-corrosion coatings 100% water based.
