Metal surface cleaning agent and preparation method thereof

Abstract

The invention discloses a metal surface cleaning agent and a preparation method thereof. The cleaning agent is prepared by mixing alkylphenol polyvinyl ether, a defoaming agent, alcohol ether, hydrogen peroxide, ethylene diamine tetraacetic acid salt, pearl powder, sodium hydroxide and deionized water. The preparation method comprises the following steps: 1, weighing alkylphenol polyvinyl ether, the defoaming agent, alcohol ether, hydrogen peroxide, ethylene diamine tetraacetic acid salt, pearl powder, sodium hydroxide and deionized water; 2, mixing the alkylphenol polyvinyl ether, alcohol ether, ethylene diamine tetraacetic acid salt, sodium hydroxide and deionized water, stirring and heating for 2-6 minutes, and naturally cooling to obtain a mixed liquid I; 3, adding the pearl powder into the mixed liquid I, and stirring for 12-16 minutes to obtain a mixed liquid II; and 4, adding hydrogen peroxide into the mixed liquid II, stirring, and finally adding the defoaming agent to obtain the cleaning agent. The cleaning agent has strong oil stain removing capability and little foam, and can be normally used at low temperature.

Description

[0001] technical field [0002] The invention relates to the field of chemical cleaning agents, in particular to a metal surface cleaning agent and a preparation method thereof. [0003] Background technique [0004] During the processing of metal parts products, oil, electrolyte, etc. are often used, so the products are often contaminated with dirt, so the processed metal parts must be cleaned. Since the greasy dirt contains fatty oil and mineral oil, dyes, soot and other upstream processes, granular dirt, metal oxides, etc., the dirt involved in the metal surface cleaning process is very extensive, and the dirt composed of these substances, after a relatively Long-term changes will form stubborn, darker, stubborn dirt on the metal surface that is difficult to achieve a good washing effect with ordinary detergents. [0005] At present, the commonly used degreasers mainly include strong acid, strong alkali and surfactant, etc. They have poor cleaning ability for heavier oi...

AI Technical Summary

Problems solved by technology

[0005] At present, the commonly used degreasers mainly include strong acid, strong alkali and surfactant, etc. They have poor cleaning ability for heavier oil stains, and they have many foams, making it difficult to rinse. The waste water contains toxic substances, pollutes the environment, and is harmful to the body of operators. cause harm, in view of the above problems, there is an urgent need to develop an environmentally friendly and efficient metal cleaning agent

[0006] The application number is 200810046015.6, which discloses a metal surface grease cleaning agent and its preparation method. The cleaning agent is mixed with alkylphenol polyvinyl ether, defoamer, fatty alcohol polyoxyethylene ether, sodium hydroxide, sodium phosphate and sodium carbonate. Although it is environmentally friendly and easy to clean, the cleaning agent contains phosphorus, which pollutes the environment
