Abstract In this study, different loading ratios of epoxy resin (E) and epoxidized soybean oil (ESO) were introduced into acrylic–silicone polymeric blend with the presence of polyisocyanate (NCO) as the curing agent. The developed coating systems were applied on pretreated cold rolled mild steel substrates and the overall performances were investigated by means of Fourier transform infrared (FTIR) spectroscopy, contact angle measurements (CA), UV–vis analysis, thermogravimetric analysis (TGA), electrochemical impedance spectroscopy (EIS) and salt spray test. Moreover, the physico-mechanical properties of all developed coating systems were investigated. The obtained results revealed the ability of the combination of E and ESO at a certain concentration specifically, 9:1, to enhance the overall performance of the polymeric matrix as optimum curing level, better wettability, good physical-mechanical characteristics, thermal stability and significantly enhanced corrosion resistance were observed. The results also demonstrated the ability of the fabricated single-layer coating system to serve as a primer, topcoat or single coating system that has promising potential to be applied for decorative, self-cleaning, thermal insulation and corrosion protection purposes.

开发具有优异防腐性能的环氧化大豆油改性全有机涂层体系

摘要 在本研究中，以聚异氰酸酯 (NCO) 作为固化剂，将不同负载比的环氧树脂 (E) 和环氧化大豆油 (ESO) 引入丙烯酸-有机硅聚合物共混物中。将开发的涂层系统应用于预处理的冷轧低碳钢基材上，并通过傅里叶变换红外 (FTIR) 光谱、接触角测量 (CA)、UV-vis 分析、热重分析 (TGA)、电化学阻抗来研究整体性能光谱（EIS）和盐雾试验。此外，研究了所有开发的涂层系统的物理机械性能。所得结果揭示了 E 和 ESO 在特定浓度下的结合能力，具体为 9:1，为了提高聚合物基体的整体性能作为最佳固化水平，观察到更好的润湿性、良好的物理机械特性、热稳定性和显着增强的耐腐蚀性。结果还证明了制造的单层涂层系统作为底漆、面漆或单涂层系统的能力，具有用于装饰、自清洁、隔热和防腐蚀目的的潜力。
