Design of Formulation and Performance Research of Water-Borne Epoxy Modefied by 3-(trimethoxysilyl)propyl Methacrylate Anti-Corrosion Coatings

Abstract:

A waterborne anticorrosive coatings was prepared with homemade organic silicone 3-(trimethoxysilyl) propyl methacrylate modified epoxy acrylate emulsion as basic material, glass flake as anticorrosive filter and titanium dioxide as pigment and other additives. The anti-acid alkali salt, AC impedance, polarization curve tests were done to evaluate the coatings’ anticorrosion properties and to optimal its formula and process. The results showed that the best formula was: glass flake 35%, particle size 80 meshes, titanium dioxide as anticorrosive pigment 18% and the emulsion with epoxy at 45% content as base material. In this case, the coatings’ anti-acid, alkali and salt’s properties is good, the impedance values was up to eight orders of magnitude, the corrosion current was 9.59 × 10^-8A and every indicator met the requirements of the JB/T224-2007 "Building with Steel Structure Anticorrosion Coatings". The water-epoxy anti-corrosion coating has safe environmental protection, zero VOC, excellent anti-corrosion properties and other indexes meet national standards.
