通过分析金属防锈剂的防锈机理，探讨了防锈剂种类、表面活性剂、水质和 pH值对金属防锈剂防锈性能的影响，并进行了试验验证。结果表明，在一定范围内相同或相似分子结构金属防锈剂的防锈性能随碳链的增长而不断提高；当分子结构中含有适当长度疏水性烃基时，其防锈性能随极性基团的增加而有所提高；某些表面活性剂会降低防锈剂的防锈性能；相对于蒸馏水，自来水则会削弱金属防锈剂的防锈性能；pH值为8～8．5时金属防锈剂对10＃钢、黄铜和LY12铝均有较好的防锈效果。
通過分析金屬防鏽劑的防鏽機理，探討瞭防鏽劑種類、錶麵活性劑、水質和 pH值對金屬防鏽劑防鏽性能的影響，併進行瞭試驗驗證。結果錶明，在一定範圍內相同或相似分子結構金屬防鏽劑的防鏽性能隨碳鏈的增長而不斷提高；噹分子結構中含有適噹長度疏水性烴基時，其防鏽性能隨極性基糰的增加而有所提高；某些錶麵活性劑會降低防鏽劑的防鏽性能；相對于蒸餾水，自來水則會削弱金屬防鏽劑的防鏽性能；pH值為8～8．5時金屬防鏽劑對10＃鋼、黃銅和LY12鋁均有較好的防鏽效果。

The effects of types of anti-rust agents,surfactants,water quality and pH on anti-rust properties of metal anti-rust agents are discussed through analyzing anti-rust mechanism for metal anti-rust agents,and the test verifi-cation is conducted.The results show that in a certain range,the anti-rust properties of metal anti-rust agents with the same or similar molecular structure are improved with the growth of carbon chain.When the molecular structure contains a hydrophobic hydrocarbon group of appropriate length,the anti -rust properties are improved with the in-crease of polar group.The certain surfactants will reduce the anti-rust properties of anti-rust agents.With respect to the distilled water,the tap water reduces the anti-rust properties of metal anti-rust agents.The metal anti-rust a-gents have good anti-rust effect on the 10#steel,brass and aluminum LY12 as pH is 8~8.5.
