Water-based micro emulsion washing liquor for mineral oil on brass surface

Abstract

The invention discloses water-based micro emulsion washing liquor for mineral oil on a brass surface. The water-based micro emulsion washing liquor comprises sodium dodecyl benzene sulfonate, laurate dihydroxyethylamide, fatty acid methyl ester polyoxyethylene ether, an organic solvent, a chelating agent, ammonium molybdate, 2-sulfydryl-benzotriazole, a polyether modified organic silicon defoamer and water; the organic solvent, the anionic surfactant sodium dodecyl benzene sulfonate and nonionic surfactants including the fatty acid methyl ester polyoxyethylene ether and the laurate dihydroxyethylamide are adopted for compounding, the chelating agent, the polyether modified organic silicon defoamer, the ammonium molybdate and the 2-sulfydryl-benzotriazole corrosion inhibitor are adopted in an assisting manner, through the manner that the permeation and dissolving performance of the organic solvent is combined with the wetting and emulsifying property of the surfactant, the water-based micro emulsion washing liquor for mineral oil on the brass surface is provided, and the effects of conducting micro emulsion washing on mineral oil agents on the brass surface and preventing the brass from discoloring are achieved.

Description

technical field [0001] The invention relates to the technical field of metal surface cleaning, in particular to a mineral oil water-based microemulsion cleaning solution for brass surfaces. Background technique [0002] Cleaning and corrosion are problems that must be faced during metal processing and product manufacturing. During the processing of brass, stamping oil, drawing oil, cutting fluid, dust, etc. will form various greases and stains on the surface of the brass, which need to be cleaned. Cleaning will affect the subsequent processing, surface condition and product quality of the product. A very important process, the liquid cleaning agent based on strong alkali has a strong ability to remove dirt, but it has a strong corrosion on the surface of brass and is easy to harm the human body; the liquid cleaning agent based on solvent mainly removes dirt through dissolution , but the solvent is flammable, explosive, and unsafe; liquid cleaning agents based on surfactants...

During the processing of brass, stamping oil, drawing oil, cutting fluid, dust, etc. will form various greases and stains on the surface of the brass, which need to be cleaned. Cleaning will affect the subsequent processing, surface condition and product quality of the product. A very important process, the liquid cleaning agent based on strong alkali has a strong ability to remove dirt, but it has a strong corrosion on the surface of brass and is easy to harm the human body; the liquid cleaning agent based on solvent mainly removes dirt through dissolution , but the solvent is flammable, explosive, and unsafe; liquid cleaning agents based on surfactants have low descaling efficiency, need to soak the dirt for a long time, and are expensive
