Embodiment 1

[0025] A vapor phase corrosion inhibitor for metals is composed of the following raw materials in parts by weight: 5 parts of 2-methyl-1H-imidazole-1-propylamine salt, 10 parts of benzotriazole, 30 parts of borax and 70 parts of distilled water.

[0026] Perform corrosion inhibition treatment on several conductive metals in a simulated high-humidity environment, and judge the corrosion inhibition effect of each corrosion inhibitor on conductive metals. The method is as follows:

[0027] A3 steel, aluminum, red copper, brass four conductive metal sheets were polished smooth with 280#, 660#, 3000# sandpaper respectively, soaked in absolute ethanol, ultrasonicated for 10min, washed with Wahaha water three times, dried with nitrogen, weighed spare.

[0028] Pour four 1125ml wide-mouth bottles into 40ml municipal tap water respectively, put 25ml small beakers into two of them respectively, and put 0.5g corrosion inhibitor in the small beakers as the experimental group; No corrosio...

Embodiment 2

[0039] A vapor phase corrosion inhibitor for metals is composed of the following raw materials in parts by weight: 10 parts of 2-methyl-1H-imidazole-1-propylamine salt, 10 parts of benzotriazole, 30 parts of borax and 60 parts of distilled water.

[0040] According to the method test in embodiment 1, each corrosion inhibitor is to the corrosion inhibition effect of conductive metal, and the results are as shown in table 2:

[0041] Table 2

[0042]

Embodiment 3

[0044] A vapor phase corrosion inhibitor for metals is composed of the following raw materials in parts by weight: 15 parts of 2-methyl-1H-imidazole-1-propylamine salt, 10 parts of benzotriazole, 30 parts of borax and 55 parts of distilled water.

[0045] According to the method test in embodiment 1, each corrosion inhibitor is to the corrosion inhibition effect of conductive metal, and the results are as shown in table 3:

[0046] table 3

[0047]

[0048] It can be seen from Table 1-3 that the formula has obvious corrosion inhibition effect on four metals, among which the corrosion inhibition effect of brass and A3 steel is particularly obvious, and with the addition of 2-methyl-1H-imidazole-1-propylamine When the proportion of salt increases, the effect becomes more obvious. When the weight part exceeds 15, the corrosion inhibition efficiency of brass and A3 steel can reach more than 70%, but the corrosion inhibition effect of aluminum has no obvious improvement, which m...

Abstract

The invention discloses a conductive metal vapor phase corrosion inhibitor and application thereof. The conductive metal vapor phase corrosion inhibitor comprises the following raw materials in parts by weight: 1-30 parts of 2-methylimidazole ammonium salt, 5-15 parts of benzotriazole, 20-30 parts of a carrier, and 50-70 parts of distilled water. The conductive metal vapor phase corrosion inhibitor has the advantages of low toxicity, universality and long acting, and can effectively protect common conductive metal.

Description

technical field [0001] The invention relates to the field of anti-corrosion, in particular to a conductive metal vapor phase corrosion inhibitor and application thereof. Background technique [0002] As my country pays more and more attention to electric energy, the electric power industry has ushered in great development in recent years. The power industry uses a large number of electronic equipment, many of which need to be placed in the outdoor atmosphere for a long time, such as power distribution cabinets, which have repeatedly experienced high temperature and high humidity environments, making the outer casing of the equipment and internal electronic equipment materials prone to aging and corrosion, and frequent equipment failures Development, shorten the service life of the equipment, and cause huge economic losses to the country every year, so effective anti-corrosion measures are urgently needed. [0003] However, the internal structure of electronic equipment is c...
