Impact of inhibitor loaded with pigments content on properties of inorganic zinc rich coatings
In order to overcome the poor dispersion of traditional inorganic zinc-rich coating, addressing the sedimentation and the agglomeration caused by high zinc powder content and improve the anti-corrosion performance of coatings.

description | In order to overcome the poor dispersion of traditional inorganic zinc-rich coating, addressing the sedimentation and the agglomeration caused by high zinc powder content and improve the anti-corrosion performance of coatings. In this paper, the molybdate intercalated hydrotalcite flake zinc layer double hydroxide (ZnAl–NO3-/LDH) was synthesized by hydrothermal synthesis method at first, and the KH560 modified the Mo/LDH flake zinc powder was further obtained by ion exchange method. The results show that the samples have a layered structure of hydrotalcite with good crystal structure through X-ray diffraction (XRD) and Fourier transform infrared (FT-IR), and the molybdate corrosion inhibiting ions inserted successfully into the interlayer structure of hydrotalcite. Meanwhile, different contents of pigments and fillers were added into the inorganic zinc-rich coatings. It was found that the Nyquist radius of curvature and modulus value of the coating were the largest with a pigment and filler content of 40 %, the maximum corrosion potential was −0.017V, and the minimum corrosion current density was 3.377 × 10−7 A-cm−2. The result indicates that the coating has the best corrosion resistance with 40 % pigment content, which has good application prospects in the fields of cross-sea bridges, natural gas and oil pipelines et al. |
