摘要

本研究采用FT-IR、UV-Vis光谱等分析方法，结合FE-SEM分析，并监测饱和Ca(OH)2碱性环境下，纳米sio2对水性丙烯酸涂料耐碱性的影响。结果表明，当纳米sio2含量为2.5 wt%时，丙烯酸涂料的耐碱性明显增强。在饱和Ca(OH)2溶液浸泡20天的影响下，纳米复合涂层含2.5 wt。纳米sio2的掺入仅使涂层重量降低3.6%，附着力降低15.4%，而未掺入纳米sio2的纯丙烯酸涂层则使涂层重量降低25.4%，附着力降低39.1%。

The Alkaline Resistance of Waterborne Acrylic Polymer/SiO2 Nanocomposite Coatings

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.
