摘要: 家电用经济型高耐蚀彩涂板的研究,包括过氧化氢腐蚀彩涂板的典型过程及机理,以及对耐过氧化氢、耐酸碱、耐中性盐雾和耐湿热等耐腐蚀方面的研究,并分析了其表面显微状态等。研究表明,彩涂板的涂层溶剂挥发通道处会被过氧化氢优先腐蚀。相比于PE彩涂板、HDP彩涂板和PVDF彩涂板,经济型高耐蚀彩涂板的耐过氧化氢性能更为优异,耐酸碱性能更为均衡,耐中性盐雾性能和耐湿热性能最为接近PVDF彩涂板,其漆膜表面显微状态较PE彩涂板更为细腻、均匀。

Abstract: The study of the economical high corrosion resistance prepainted steel sheet for home appliances included the corrosion mechanism of hydrogen peroxide on the prepainted steel sheet, the corrosion resistance of hydrogen peroxide, acid, alkali, neutral salt spray, humidity and heat, the surface microscopic state and so on. The research showed that hydrogen peroxide preferentially corroded along the evaporation channels of the coating solvent in prepainted steel sheet. Compared with PE, HDP and PVDF, the economical high corrosion resistance prepainted steel sheet had a better resistance of hydrogen peroxide, more balanced resistance of acid and alkali, and the resistance of neutral salt spray, humidity and heat was closest to PVDF. The micro-state surface of the economical high corrosion resistance prepainted steel sheet was more delicate and uniform than PE.

Key words: High corrosion resistant, Economical, Prepainted steel sheet, Hydrogen peroxide
