Characterization of epoxy based coating reinforced with nanoparticles of silica sand

Abstract

Steel structures and pipelines can be saved from environmental effects by epoxy based coating. This research has been focused to reinforce locally developed nanoparticles of silica sand in epoxy based coating on mild steel grade 1020. Four samples of mild steel were thoroughly polished and coated with 1, 2, 3, and 4 wt.% of nanoparticles of silica sand epoxy based coating. Scanning Electron Microscope (SEM) with EDAX was used to analyze char microstructures. FTIR analysis was used to study the variation in transmittances by increasing the addition of nanoparticles of silica sand in epoxy coating. Hardness of epoxy based coating was increased with increasing the amount of nanoparticles of silica sand in epoxy. The epoxy based coating with nanoparticles of silica sand was found more stable at higher temperatures as shown in the thermo gravimetric analysis (TGA). This type of epoxy coating on mild steel can be used for gas pipelines for environmental protection.
