以电解锌粉（锌含量约93％）为原料，蒸馏水为研磨介质，采用高能振动球磨法研究片状锌粉制备，并通过添加缓蚀剂，考察缓蚀剂种类及其复配对制备片状锌粉过程中的缓蚀效果。结果表明，添加苯并三唑（BTA）、聚乙二醇400（PEG-400）、Na2SiO3均可延缓锌粉在球磨过程中的腐蚀。其中BTA（或PEG-400）与Na2SiO3复配的缓蚀效果要优于单一组分缓蚀剂。最佳缓蚀剂组分为0．5％BTA与0．15％NazSiO3复配。球磨过程中片状锌粉有少量消耗，粒度逐渐减小，球磨1h后片状锌粉活性锌含量和平均粒径可达到达克罗涂层使用要求。
Zinc flakes were prepared by high-energy vibration milling, using electrolytic zinc powders (wZn% = 93%) as raw material and distilled water as grinding medium. By adding corrosion inhibitors in the medium, anti- corrosion effect of several inhibitors and their combinations were investigated during the milling process. The results show that adding BTA, PEG-400 or Na2SiO3 can reduce the corrosion of zinc flakes, among them the combination of BTA (or PEG-400) and Na2SiO3 got better efficiency than a single component inhibitor. Optimized inhibitor component was 0. 5% BTA combined with 0. 15% Na2SiO3. During the milling zinc flakes had a little decrease and became finer. By lh milling, the content of Zn and average grain diameter of the zinc flakes reached the Dacromet demands.
