Description
Summary:Floor coating is a contemporary technique used to substitute traditional flooring materials like ceramic, oak, and alabaster with epoxy paint. The properties of epoxy floor coatings were studied in terms of mechanical properties, wear resistance, and tribological properties. Nano-clays (MMT for epoxy) were added for reinforcement in different proportions (0, 0.5, 1, 2, and 4 wt.%) using the ultrasound dispersing device. The results show that the wear resistance of the nanocomposite coating reinforced with 2% nanoclay is improved by 82% compared to pure epoxy. The hardness increases by about 13.8% and 19.7% when the nanoclay content is 0.5% and 4%, respectively, compared to pure epoxy, while the adhesive strength decreases with increasing the weight percentage of nanoclay in the composites. In addition, results show that scratch hardness improved by 37.5% and 118.75% when nanoclay content was 0.5% and 4%, respectively.
