摘要

环氧聚合物是一种杰出的屏障防腐涂层，用偏高岭土（一种环保的无机填料）增强了镀锌钢板在水中和酸性环境中的屏障防腐性能。各种比例0、1、3、5和7 将wt%的偏高岭土填料与kadilux环氧树脂本质混合，并分别根据ASTM G31表征热稳定性、吸水性和根据ASTM D-570标准表征酸浸渍。增强涂层使孔径和密度最小化，吸水率更低，耐酸性能更好，尤其是在7 填料的重量%。薄膜的热稳定性提高到5以上填料组合物的重量%。

Barrier Corrosion Protection Properties of Metakaolin Clay-Kadilux Epoxy Coatings on Galvanized Steel

Epoxy polymer, an illustrious barrier corrosion protective coating, was reinforced with metakaolin clay, an eco-friendly inorganic filler to enhance the barrier corrosion protection properties in water and in acidic environment on galvanized steel plates. Various proportions 0, 1, 3, 5, and 7 wt.% of metakaolin fillers were mixed intrinsically with kadilux epoxy and characterized for thermal stability, water absorption according to ASTM G31, and acid immersion according to ASTM D-570 standards, respectively. The reinforced coatings minimized the pore size and density, lower water absorption, and better acid resistance properties especially at 7 wt.% of the fillers. The thermal stability of the films improved beyond 5 wt.% of filler composition.
