Metal oil removal agent and use method thereof

Abstract

The invention provides a metal oil removal agent. The agent comprises raw materials including, by weight part, 4 to 12 parts of potassium hydroxide, 10 to 20 parts of fatty alcohol polyoxyethylene ether sodium sulfate, 5 to 10 parts of polyaspartic acid, 0.5 to 2 parts of oxidized starch, 10 to 20 parts of cetyl-trimethyl ammonium bromide, 15 to 25 parts of butyl cellosolve, and 4 to 10 parts of sodium pyrophosphate. The invention further provides a use method of the metal oil removal agent. Under the normal temperature state, the metal oil removal agent has the higher dissolving capacity on various kinds of grease, heavy oil and aging deteriorated grease can be dissolved, the cleaning speed is high, the higher dispersion and anti-staining capacity can be achieved, the stain removal capacity is high, oil dirt of workpiece cleaning can be prevented from reversely contaminating the metal surface, the raw material cost is reduced, the cleaning effect is improved, and the cleaning time isshortened.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a metal degreasing agent and a using 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 the air and destroy the ozone l...

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
