| 摘 要： | 涂料在聚合过程中会产生体积收缩,而体积收缩将导致涂层的附着强度大大降低,还可能加速涂层老化的进程。本研究采用三维数字显微镜测试、扫描电镜测试和电化学交流阻抗谱测试等检测方法,对不同体积收缩率的无溶剂环氧涂层进行了性能分析,明确了体积收缩率对无溶剂环氧涂层的微观结构及防腐性能的影响。研究结果表明,调整颜基比可以控制无溶剂环氧涂层体积收缩率的大小;具有较小体积收缩率的涂层其抗渗透能力较好,具有较好的涂层防腐性能。 |
| 关 键 词： | 无溶剂环氧涂料 体积收缩率 颜基比 防腐性能 |

| Abstract: | The volume shrinkage during the coating polymerization process will result in lowering coating adhesive strength and may accelerate the ageing process of coatings film.In this paper,the performance of the solvent-free epoxy coating with the different volume shrinkage ratio was studied and analyzed by means of 3D stereomicroscope,scanning electron microscope(SEM) and electrochemical impedance spectroscopy(EIS),and the effect of volume shrinkage on microstructure and corrosion protective performance of solven... |
| Keywords: | solvent-free epoxy coatings volume shrinkage ratio ratio of pigment and binder anticorrosion performance |
