Embodiment 1～12、 comparative example 1～30

[0116] According to the components and composition (mass %) shown in Tables 1-6, the cleaning composition for metals was prepared. Specifically, (G) ion-exchanged water was added and mixed with (A) component and (C) component to make it uniform, and (B) component, (D) component, and (E) component were added and mixed, and it prepared. The metal cleaning compositions obtained in Examples 1 to 12 and Comparative Examples 1 to 30 were diluted with ion-exchanged water to adjust to a 3% by mass aqueous solution, and this was used as a test solution for the following evaluation tests.

[0117] In the table, details of the components of *1 to *7 are as follows.

[0118] *1: Sodium polyacrylate (weight average molecular weight 6000)

Abstract

A metal cleanser composition containing: (A) at least one kind of carboxylic acid compound selected from the group consisting of aliphatic monocarboxylic acids, polycarboxylic acids and neutral saltsthereof; (B) a specified oxyalkylene group-containing compound; and (C) at least one kind of compound selected from the group consisting of specified organic phosphonic acids and salts thereof as wellas specified nitrogen-containing heterocyclic compounds.

Description

technical field [0001] This invention relates to detergent compositions for cleaning metal. Background technique [0002] In recent years, with the globalization of the parts market for automobiles, trains, aircraft, machine tools, etc., low-priced parts have entered the market, and domestic parts manufacturers have been exposed to fierce cost competition. Therefore, in order to maintain competitiveness, each company that is a component manufacturer has carried out various cost reductions in materials and manufacturing processes. [0003] As one example of cost reduction in the manufacturing process, normal temperature of the cleaning process was performed. By performing the cleaning of components at a relatively high temperature at room temperature, heating of the cleaning bath is no longer necessary, and energy cost reduction can be expected. On the other hand, detergency, defoaming, etc. The performance degradation required in the cleaning process becomes a problem. ...
