Embodiment 1～7、 comparative example 1～36

[0062] Various carboxylic acids shown in Table 1 were mixed with N-methyldiethanolamine and diluted with water to prepare aqueous amine salt solutions of carboxylic acids. This amine salt aqueous solution was used as a sample, and the rust prevention and hard water stability were evaluated. The evaluation results are also shown in Table 1. The evaluation method is as follows.

[0063] (Evaluation method of rust resistance)

[0064] 1) Measure 2.00g of N-methyldiethanolamine and carboxylic acid in a 100mL beaker such that "amine / acid equivalent ratio = 3".

[0065] 2) Add about 20 mL of ion-exchanged water, and dissolve it uniformly while heating and stirring.

[0066] 3) Quantitatively transfer the dissolved amine salt solution into a 100mL graduated cylinder with a stopper, dilute it with ion-exchanged water, and set the volume to 100mL to prepare an aqueous solution with a concentration of 2.0g / dL.

[0067] 4) Mix the ion-exchanged water and the above aqueous solution at...

Embodiment 8、9、10

[0083] Examples 8 and 9 in Table 2 show recipes (stock solutions) that are assumed to be cleaning agents for both iron and aluminum, and Example 10 shows recipes (stock solutions) that are supposed to be cleaning agents dedicated to aluminum. These stock solutions were diluted with water and evaluated. Specifically, in addition to the above-mentioned rust resistance and hard water stability, defoaming and the degree of discoloration of the aluminum flakes were evaluated by the methods shown below.

[0084] (defoaming)

[0085] Evaluation was performed by a cylinder method (Silinder method). Specifically, 98 mL of tap water was placed in a 100 mL graduated cylinder with a stopper, 2 mL of the stock solution was added, and lightly shaken to prepare a 2% by volume dilution. Vigorously shake the barrel up and down for 5 seconds, then let it stand. The time at which 50% of the liquid interface was observed was recorded as defoaming time (seconds).

Abstract

An aqueous detergent according to the invention contains substantially no polyalkylene glycol, but contains a salt of at least one of the following carboxylic acids A, B and C: A: an aliphatic monobasic carboxylic acid having a total carbon number of 9 or 10 and including a branched alkyl group; B: sebacic acid; and C: an aromatic monobasic carboxylic acid having a total carbon number of 11 to 13.

Description

[0001] This application is a divisional application of the invention patent application filed on March 13, 2013 with the title of invention "water-based cleaning agent" and national application number 201180044063.1. technical field [0002] The present invention relates to an aqueous cleaning agent used for cleaning machine parts and the like. Background technique [0003] There are oil-based and water-based metalworking oils used in metalworking and cleaning as a subsequent process, and in many cases, water-based fluids are used that are excellent in cooling and wettability, and have no risk of fire. Generally, water-based cutting oil / grinding oil / cleaning oil is used by diluting the stock solution to 1 to 200 times with water. [0004] In the manufacturing process of automobiles and machine parts, when an emulsion-based water-soluble machining oil is used, if it is directly dried, there are problems that chips remain and the surface becomes sticky. Therefore, washing wit...
