In the long-term working state, stains such as dust, oil, and charged particles in the environment are prone to deposit on the surface of the power equipment, which has great security risks. To achieve anti-stain performance, fluorocarbon composite coating with a low surface energy was prepared and studied. In this paper, SiO nanoparticles were used as inorganic fillers and fluorocarbon resin was used as the substrate to form anti-stain coatings. By adjusting and optimizing the ratio of fillers and organic resins, coatings with different static contact angles were constructed. The optimum composite coating has a contact angle of 151 ± 2° and a surface energy of 9.6 mJ/m. After high-temperature treatment (up to 200 °C), immersion in corrosive solutions (pH 3-11), and sandpaper abrasion (after 5 abrasion cycles), the coating has been proven to show good thermal, chemical and mechanical stability. Our study provides significant research and market opportunities for the anti-stain application of the fluorocarbon composite coating on power equipment.
在长期运行状态下，环境中的灰尘、油污和带电粒子等污渍容易沉积在电力设备表面，存在很大的安全隐患。为实现防污性能，制备并研究了具有低表面能的氟碳复合涂层。本文以SiO纳米颗粒为无机填料，以氟碳树脂为基体形成防污涂层。通过调整和优化填料与有机树脂的比例，构建了具有不同静态接触角的涂层。最佳复合涂层的接触角为151±2°，表面能为9.6 mJ/m²。经过高温处理（高达200°C）、浸泡在腐蚀性溶液（pH值3 - 11）以及砂纸磨损（5次磨损循环后），该涂层已被证明具有良好的热稳定性、化学稳定性和机械稳定性。我们的研究为氟碳复合涂层在电力设备防污应用方面提供了重要的研究和市场机遇。
