中文摘要:

      目的 研究基于苯并三氮唑（BTA）复配气相缓蚀剂涂布制成的气相防锈纸的缓蚀性能。方法 以苯并三氮唑作为主缓蚀剂，采用正交试验与碘化钾、钨酸钠、乌洛托品、尿素进行复配，研究分析气相防锈纸在氯化钠溶液条件下对碳钢和10号钢的缓蚀性能。结果 当苯并三氮唑、碘化钾、钨酸钠、乌洛托品、尿素的质量份配比为12∶12∶8∶12∶25时，对碳钢的缓蚀效率达到91.07%；当苯并三氮唑、碘化钾、钨酸钠、乌洛托品、尿素的质量份配比为12∶20∶8∶16∶25时，对10号钢的缓蚀效率达到90.17%。结论 基于苯并三氮唑复配高效气相缓蚀剂涂布制备的气相防锈纸不仅绿色环保、安全无毒，而且缓蚀效率高于市售气相防锈纸，具有优良的防锈性能。

英文摘要:

      The work aims to study the corrosion inhibition of gaseous phase antirust paper after coated by the BTA-based compound gaseous phase corrosion inhibitor. BTA was used as the main corrosion inhibitor to be compound with the potassium iodide, sodium tungstate, urotropine and urea by orthogonal test. The corrosion inhibition of carbon steel and No.10 steel by gaseous phase antirust paper in sodium chloride solution was studied. When the mass ratio of BTA, potassium iodide, sodium tungstate, urotropine and urea was 12∶12∶8∶12∶25, the corrosion inhibition rate of carbon steel reached 91.07%. When the mass ratio of BTA, potassium iodide, sodium tungstate, urotropine and urea was 12∶20∶8∶16∶25, the corrosion inhibition rate of No.10 steel reached 90.17%. The gaseous phase antirust paper coated by the BTA-based compound efficient gaseous phase corrosion inhibitor is not only green, safe and non-toxic, but also has a much higher corrosion inhibition rate than the marketed gaseous phase antirust paper. It also has excellent anti-corrosion performance.
