Problems solved by technology

[0004] In recent years, non-flammable fluorine-based solvents such as hydrofluorocarbons (hereinafter referred to as HFC) or hydrofluoroethers (hereinafter referred to as HFE) that do not contain chlorine atoms have been proposed that do not have the potential to deplete the ozone layer. Atoms, so the solubility is low, and it cannot be used alone as a cleaning agent. In patent documents 1 to 3, it is disclosed that the cleaning agent obtained by adding a high boiling point solvent to HFC or HFE is used for cleaning, and then HFC or HFE is used as a rinse agent.

Embodiment 1～20

[0277] Each component was mixed according to the composition described in Table 1 to obtain the target detergent composition. The (1) oil solubility test mentioned later was performed about each cleaning composition, and Table 1 summarized the result. A cleansing agent excellent in oil solubility is obtained by using the component (A) and the component (B) in combination. In addition, in the composition of the combination of component (b1) and component (b5), it was confirmed that a higher cleaning effect.

[0278] In addition, by adding a compound selected from the group consisting of alcohols, ketones, esters and hydrocarbons as component (C), it can be seen from the comparison results between Example 1 and Example 20 that it has been confirmed that component (b) Oil solubility is further improved.

Embodiment 21～27

[0282] Each component was mixed according to the composition described in Table 2 to obtain the target detergent composition. Table 2 summarizes the results of the degreasing and cleaning property test described later using the cleaning composition. Excellent detergency against oil has been confirmed by cleaning with a detergent composition and a rinse composition containing components (A) and (B) at different concentrations, and steam cleaning with steam obtained by heating the detergent composition .

Embodiment 28～47

[0310] Each component was mixed according to the composition described in Table 3 to obtain the target detergent composition. The (3) oil solubility test mentioned later was performed about each cleaning composition, and Table 3 summarized the result. A cleansing agent excellent in oil solubility is obtained by using the component (A) and the component (B) in combination. In addition, in Examples 37 to 42, the immersion test of (4) butyl rubber mentioned later was performed, and the damage (weight change) to a resin-made member was confirmed. The results are summarized in Table 3.

[0311] (3) Oil solubility test

[0312] Add 0.5 g of metal processing oil (trade name: Yusiron Former CF-6120, produced by Yusiro Chemical Industry Co., Ltd.) to 4.5 g of the cleaning composition at 25° C., vibrate with an oscillator for 2 minutes (60 times / min), and statically After standing for 5 minutes, the solubility was evaluated visually. Evaluations are based on the following criteria. ...

Abstract

Provided is a cleaning agent or the like, which exhibits high cleaning power with respect to processing oils that contain a large amount of a poorly soluble component, and which has less possibility of ozone depletion and global warming. A cleaning agent composition contains (A) a fluoropropene compound represented by general formula (1) and (B) one or more compounds selected from the group consisting of organic compounds having an ether bond and / or an ester bond, hydrocarbons and polyhydric alcohols, each one of which has a vapor pressure at 20 DEG C of 1.33*10<-2> Pa or more but less than 1.33*10<3> Pa. In the formula, C3H(6-a-b)FaClb (1), a represents an integer of 1-5 and b represents an integer of 1-3, provided that (a+b) is an integer of 2-6.

Description

technical field [0001] The present invention relates to a novel cleaning agent composition, a novel rinse agent composition and a novel cleaning method. Background technique [0002] Various processing oils used in the processing of precision mechanical parts, optical mechanical parts, etc., such as cutting oil, stamping oil, drawing oil, heat treatment oil, anti-rust oil, lubricating oil, etc., grease or wax stains must be removed in the end , usually by solvent removal. In addition, fluxes used in the soldering of electrical and electronic parts, inks or pastes adhering to the screen used in substrate manufacturing, or resins adhering to the mixing head of the resin discharge device are also usually removed with solvents. . [0003] Conventionally, in these cleaning and removal, 1,1,2-trichloro-1,2,2-trifluoroethane has been used due to its nonflammability, low toxicity, and excellent solubility. (hereinafter referred to as CFC113) or a mixture of CFC113 and alcohol for...
