摘要：

This study presents a study on the influence of nano-SiO2 on the alkaline resistance of waterborne acrylic coating using some analysis methods such as FT-IR and UV-Vis spectroscopy, combined with FE-SEM analysis and monitoring weight and adhesion changes during exposure to the saturated Ca(OH)(2) alkaline environment. The obtained results indicated that the alkaline resistance of acrylic coating enhanced appreciably when adding 2.5 wt% of nano-SiO2. Under the impact of the saturated Ca(OH)(2) solution for 20 days of immersion, nanocomposite coating containing 2.5 wt.% of nano-SiO2 was only decreased by 3.6% of the weight and 15.4% of the adhesion, while the neat acrylic coating (without nano-SiO2) seriously reduced 25.4% of the weight and 39.1% of the adhesion.
