Synergistic formulations were developed with nano-pigments, and their effects on the mechanical properties on steel substrates and structures were evaluated. This paper provides a complete analysis of the epoxy coating, focusing on the incorporation of nano-pigments and their synergistic effects in obtaining higher mechanical properties. This study reports the preparation of epoxy nano-silica composites, their characterization, and the development of coatings based on nano-silica and ZnO particles. In this composite, epoxy resin was incorporated with SiO as the main pigment and ZnO as a synergistic pigment to achieve high-performance epoxy coatings for multiple applications. The mechanical properties of these coatings (ESZ1-ESZ3) were evaluated by nanoindentation, and were used to measure the enhanced durability of nanocomposite coatings developed with synergistic formulations with different types of nanoparticles. Their performance was evaluated before and after exposure to a 3.5% NaCl solution to examine the changes of hardness and elastic modulus. The results showed that the nanoindentation technique, in conjunction with Fourier transform infrared spectroscopy and X-ray diffraction, could examine the durability and predict the service life of nanocomposite coatings. A correlation was observed between the modulus and hardness before and after exposing epoxy composite coatings (ESZ1-ESZ3) to a 3.5% NaCl solution.
采用纳米颜料开发了协同配方,并评估了它们对钢基材和结构力学性能的影响。本文对环氧涂层进行了全面分析,重点关注纳米颜料的加入及其在获得更高力学性能方面的协同效应。本研究报告了环氧纳米二氧化硅复合材料的制备、表征以及基于纳米二氧化硅和氧化锌颗粒的涂层开发。在这种复合材料中,环氧树脂与作为主要颜料的二氧化硅和作为协同颜料的氧化锌混合,以实现适用于多种应用的高性能环氧涂层。通过纳米压痕法评估了这些涂层(ESZ1 - ESZ3)的力学性能,并用于测量用不同类型纳米颗粒的协同配方开发的纳米复合涂层增强的耐久性。在暴露于3.5%氯化钠溶液之前和之后评估了它们的性能,以检查硬度和弹性模量的变化。结果表明,纳米压痕技术与傅里叶变换红外光谱和X射线衍射相结合,可以检测纳米复合涂层的耐久性并预测其使用寿命。在将环氧复合涂层(ESZ1 - ESZ3)暴露于3.5%氯化钠溶液之前和之后,观察到模量和硬度之间存在相关性。
