preparation example Construction

[0013] The preparation method of the cleaning agent composition of the present invention comprises mixing and dissolving each component in the composition. Wherein, the order of adding each component is not particularly limited, and may be added together or separately.

[0014] Different from conventional acid cleaning agents in the prior art, the cleaning agent composition of the present invention is alkaline, has a pH value of 10-12, does not cause corrosion to metal surfaces, and is therefore suitable for cleaning metal surfaces, especially copper, aluminum and Aluminum alloy surface, it is very effective to remove N32HL hydraulic oil, gasoline, animal grease and other oil stains on the metal surface, and can also be used to remove the oxide layer on the metal surface. The articles may thus be various metal articles, especially copper, aluminum and aluminum alloy articles. The application method can be various conventional methods, such as dipping and spraying methods.

Abstract

The invention provides a cleaning agent composition which comprises a surfactant and an organic assistant, wherein, the surfactant comprises OPEO with the chemical formula: C8H17ArO(CH2CH2O)nH, wherein, Ar is phenyl, n is equal to 3 to 40, and the organic assistant comprises aminoethyl ethanolamine. When cleaning a metal surface by a cleaning agent prepared by the cleaning agent composition, the cleaning efficiency is high and little foam is generated when using a spraying method to clean the metal surface.

Description

technical field [0001] The present invention relates to a cleaning composition. Background technique [0002] CN 1597893A discloses a detergent composition, which is characterized in that: the composition and weight percentage of detergent are sodium hydroxide 30-50; trisodium phosphate 10-30; sodium tripolyphosphate 1-10; sodium pyrophosphate 1 -10; anhydrous sodium sulfate 5-15; sodium metasilicate nonahydrate 10-20; nonionic surfactant 1-10; citric acid and / or oxalic acid tetraacetic acid 1-10. Wherein, the nonionic surfactant can be polyether type fatty acid ester, fatty acid polyoxyethylene ether or anionic surfactant fatty alcohol polyoxyethylene ether sodium sulfate. [0003] The above-mentioned disclosed detergent has the defects of low cleaning rate and many bubbles when cleaning the metal surface by spraying. In addition, the above-mentioned detergent composition contains trisodium phosphate, sodium tripolyphosphate and Phosphorus-containing compounds of sodium p...
