Epoxy resin was directly grafted onto the surface of mica powder by high-temperature mechanical ball milling. This method was used to achieve a chemical reaction between the epoxy resin and mica that cannot be carried out under conventional circumstances. The results show that an epoxy resin layer with a thickness of approximately 10 nm formed on the surface of the mica. This modified mica filler exhibited a significant change in its hydrophilic properties. The dispersion of mica and its compatibility with organic coatings also significantly improved. In addition, the modified mica filler was added to the epoxy coating. The improvement of the coating's compactness and toughness is the reason for its anti-corrosion performance enhancement.
通过高温机械球磨将环氧树脂直接接枝到云母粉表面。该方法用于实现环氧树脂与云母之间在常规条件下无法进行的化学反应。结果表明,云母表面形成了厚度约为10nm的环氧树脂层。这种改性云母填料的亲水性发生了显著变化。云母的分散性及其与有机涂层的相容性也得到了显著改善。此外,将改性云母填料添加到环氧涂层中。涂层致密性和韧性的提高是其防腐性能增强的原因。
