Abstract

The invention discloses a sterilizing water-based antirust liquid comprising the raw materials in parts by weight: 10-20 parts of monoethanolamine, 4-6 parts of boric acid, 30-35 parts of dimethyl sebacate, 1-3 parts of sodium tungstate, 2-4 parts of sodium molybdate, 3-5 parts of ethylenediaminetetraacetic acid disodium salt, 0.2-0.4 part of a defoaming agent, 0.2-0.3 part of sodium dodecyl sulfate, 0.1-0.3 part of a bactericide, and 45-55 parts of water. The invention also discloses a preparation method of the sterilizing water-based antirust liquid. The sterilizing water-based antirust liquid has the advantages of good antirust performance, sterilization, corrosion prevention, and no pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of antirust liquid, in particular to a sterilizing water-based antirust liquid and a preparation method thereof. Background technique [0002] Metals are easily corroded by the surrounding environment. People usually choose anti-rust oil for surface treatment of metals, but the anti-rust oil is not easy to remove, which will bring trouble to the subsequent process; water-based anti-rust liquid will not affect the subsequent process, but the early water-based anti-rust liquid contains nitrous acid Salt will cause damage to people and the environment; there are also water-based anti-rust solutions containing phosphating solutions, which can avoid harm to the human body, but because they contain a lot of phosphorus, it is easy to cause eutrophication of water bodies; currently, some water-based anti-rust solutions on the market The anti-rust liquid avoids the problem of environmental pollution, but the anti-ru...
