Anti-corrosion oil remover for metal surface and using method of anti-corrosion oil remover

Abstract

The invention provides an anti-corrosion oil remover for a metal surface. The anti-corrosion oil remover comprises the following raw materials in parts by weight: 4-12 parts of sodium stearate, 10-20parts of sodium carbonate, 5-10 parts of polyaspartic acid, 0.5-2 parts of oxidized starch, 10-15 parts of cetyl-trimethyl ammonium bromide, 15-25 parts of propanediol butyl ether, 4-10 parts of sodium citrate and 1-5 parts of sodium pyrophosphate. The invention provides a using method of the anti-corrosion oil remover for the metal surface. Under a normal-temperature state, the anti-corrosion oilremover for the metal surface has very strong dissolving capacity on various kinds of grease, can dissolve heavy oil, can age deteriorated grease, is high in cleaning speed, has very strong dispersing and pollution-preventing ability, is strong in detersive power, can prevent greasy dirt generated after cleaning a workpiece from polluting the metal surface, reduces the raw material cost, improvesthe cleaning effect and shortens cleaning time.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to an anti-corrosion and degreasing agent for metal surfaces and a use method thereof. Background technique [0002] Metal cleaning is one of the indispensable processes in mechanical processing, because in different metal processing processes, various types of dirt may adhere to the surface of metal parts and equipment. Only by fully cleaning these dirt can the next process be guaranteed. The smooth progress and the processing quality of the product. For different types of dirt, chemical alkali cleaning (removing animal and vegetable oils), organic solvent cleaning (dissolving dirt by solvents) and single emulsifier cleaning are often used. Chemical alkali washing has a strong ability to remove animal and vegetable oils, but it is difficult to remove mineral oil stains, and the use temperature is relatively high. Solvent cleaning will directly pollute ...

AI Technical Summary

Problems solved by technology

[0003] The biggest defect of the degreasing products in the prior art is poor dispersibility, and the degreasing oil is easy to contaminate the surface of the workpiece to be cleaned, so the final effect of degreasing is relatively poor

Especially for metal parts with a lot of oil and rust, the cleaning effect is poor; there are many foams, which affect the effect of degreasing and cleaning after degreasing; and it is easy to cause corrosion to more active metals such as aluminum, which affects subsequent processing
