Water-based environment-friendly anti-rust agent for metal

[0070] Example 1: A metal water-based environmental protection rust inhibitor, which is composed of the following parts by weight of raw materials: the composite acid is 20 parts;

[0071] The ethanolamine is 10 parts;

[0072] The triethanolamine is 6 parts;

[0073] The monoethanolamine is 12 parts;

[0074] The neutralizer is 3 parts;

[0075] The defoamer is 3 parts;

[0076] The leveling agent is 1 part;

[0077] The flavoring agent is 1.1 parts;

[0078] The water is 80 parts.

[0079] Example 2: A water-based environmental protection rust inhibitor for metal, which is composed of the following parts by weight of raw materials: the composite acid is 30 parts;

[0080] The ethanolamine is 8 parts;

[0081] The triethanolamine is 8 parts;

[0082] The monoethanolamine is 8 parts;

[0083] The neutralizer is 6 parts;

[0084] The defoamer is 2 parts;

[0085] The leveling agent is 1.5 parts;

[0086] The flavoring agent is 0.5 parts;

[0087] The water is 90 parts.

[0088] Example 3: A water-based environmental protection rust inhibitor for metals, consisting of the following parts by weight of raw materials: 22 parts of the composite acid;

[0089] The ethanolamine is 8.5 parts;

[0090] The triethanolamine is 7.2 parts;

[0091] The monoethanolamine is 9 parts;

[0092] The neutralizer is 5 parts;

[0093] The defoamer is 2.2 parts;

[0094] The leveling agent is 1.1 parts;

[0095] The flavoring agent is 0.8 parts;

[0096] The water is 82 parts.

[0097] The anti-rust agent in the above-mentioned embodiment includes compound acid, ethanolamine, triethanolamine, monoethanolamine, neutralizer, defoamer, leveling agent, flavoring agent and water. The ratio is reasonable and water-based raw materials are used to prepare the antirust agent. The rust agent is environmentally friendly and its performance meets the standard. The anti-rust period is as long as 1-1.5 years. It is especially suitable for the anti-rust of finished metal parts;
