Efficient metal corrosion inhibitor and preparation method thereof

Abstract

The invention relates to an efficient metal corrosion inhibitor, which is prepared from the following raw materials in parts by weight: 15 to 25 parts of sodium tungstate, 40 to 60 parts of ethylene glycol, 7 to 15 parts of ethyl alcohol, 20 to 30 parts of monoethanolamine, 4 to 9 parts of ammonium citrate, 40 to 60 parts of zirconium carbonate, and 250 to 350 parts of water. A preparation method comprises the following steps of adding the water in a glass container, adding the sodium tungstate, and stirring for dissolving; and then sequentially adding the ethylene glycol, the ethyl alcohol, the monoethanolamine, the ammonium citrate and the zirconium carbonate, and stirring for dissolving to obtain the efficient metal corrosion inhibitor provided by the invention. The efficient metal corrosion inhibitor provided by the invention has no need to be water-washed after being used, and can be directly sprayed with oil paint, the oil paint cannot be bubbled or fallen off, and the painting film adhering capacity achieves 0 degree.

Description

technical field [0001] The invention belongs to the technical field of metal corrosion inhibition, and in particular relates to a high-efficiency metal corrosion inhibitor and a preparation method thereof. Background technique [0002] General construction machinery parts must be cleaned and then painted before assembly. The heavy oil and heavy dirt on the surface of these parts are dry and hard to remove. At this time, general construction machinery manufacturers use shot blasting and sand blasting to remove the oil stains on the surface, and then use special metal corrosion inhibitors for degreasing and antirust treatment, without washing, and spray paint directly after drying. [0003] Generally, metal corrosion inhibitors or antirust agents on the market can also be used for antirust treatment, but their compatibility with paint is poor. Spraying paint directly without washing after antirust treatment will cause the paint to foam and fall off. Contents of the inventio...
