中文摘要:
      目的 获得一种防腐性能优越的转化膜。 方法 将 KH560 和 KH791 两种硅烷复合后水解,添加硝酸锆,得到 KH560 -KH791 -硝酸锆复合钝化液,采用该钝化液对镀锌钢板进行钝化处理,通过盐水浸泡实验、中性盐雾试验和附着力测试,与添加硝酸锆前的转化膜进行性能对比。 结果 盐水浸泡和中性盐雾腐蚀 72 h 的实验中,添加硝酸锆后的转化膜性能都明显优于添加前,二者的附着力测试均能达到一级。 结论 加入的硝酸锆填充了膜层空隙,更加有效地阻挡了腐蚀介质的渗透,使得钝化膜的防腐性能提高。
英文摘要:
      Objective To get a conversion coating with superior anti-corrosion performance. Methods The KH560-KH791-zirconium nitrate composite passivation solution was obtained by means of compositing and hydrolyzing two organic silanes followed by addition of zirconium nitrate. The solution was used on the galvanized sheet and the performances of the conversion coatings formed were comparatively characterized by salt water immersion testing, neutral salt spray testing and adhesion testing with the coatings prepared without adding zirconium nitrate. Results In the 72 h salt water immersion test and neutral salt spray test, the conversion coating prepared with the addition of zirconium nitrate was much better than that prepared without zirconium nitrate addition, and in both cases the adhesion test results reached Level 1. Conclusion the participation of corrosion inhibitor zirconium nitrate may fill the gaps in the coating, resulting in higher resistance to penetration of corrosive medium and further improvement of the anti-corrosion performance of the passivated coating.
