INDUSTRIAL APPLICATION FIELD The present invention relates to a liquid cleaning agent for cleaning flux used in soldering. BACKGROUND OF THE INVENTION Fluxes are used in the electronics industry when soldering printed circuit boards.
In order to maintain the high quality of printed circuit boards and final products, such fluxes are required to be cleaned to a high degree of cleanliness after soldering work is completed. Various cleaning agents for fluxes have been disclosed in the past, for example, Japanese Patent Application Laid-Open No. 1983-1999.
Publication No. 227998, Publication No. 61-37363, Publication No. 61-42474
It has been reported in the No. However, all of these cleaning agents are compositions based on fluorocarbon-based solvents and chlorinated solvents,
In recent years, the environmental safety of these solvents has been compared, and there has been an increasing demand for water-based cleaning agents to replace solvent-based cleaning agents. Problems to be Solved by the Invention The present invention provides an aqueous liquid cleaning agent that has excellent cleaning performance for solder flux and has no problems with respect to environmental safety. Structure of the Invention The liquid cleaning agent for solder flux of the present invention is characterized by containing a compound represented by the following general formula (), or further a compound represented by the general formula (). R 1 -O(-C o H 2o O) - n H...() (R 1 : Alkyl group or alkenyl group having 1 to 5 carbon atoms) n: Number of 2 to 4 m: Number of 1 to 10) R2 -O( -C2H4O ) -lH ...() ( R2 : Alkyl group or alkenyl group having 8 to 18 carbon atoms or alkylphenyl group having 12 to 25 carbon atoms l: 5 to 15 The present invention will be described in more detail below. The compound of the above general formula () is an alkylene oxide adduct of a saturated or unsaturated alcohol having 1 to 5 carbon atoms. C o H 2o O in the formula indicates that oxyethylene, oxypropylene, or oxybutylene is added alone or as a mixture, and a block adduct of oxyethylene and oxypropylene is particularly preferred. n indicates the average number of moles of alkylene oxide added, and is 1 to 10, preferably 2
~6. In the case of block addition of oxyethylene and oxypropylene, oxyethylene 1 to 3
1 to 5 moles of oxypropylene are preferred. The compound of general formula () includes an ethylene oxide adduct of a saturated or unsaturated alcohol having 8 to 18 carbon atoms, and an ethylene oxide adduct of an alkylphenol having 12 to 25 carbon atoms, including a benzene ring. In the former case, a secondary alcohol having 10 to 16 carbon atoms is preferred, and in the latter case, octylphenol and nonylphenol are preferred. The average number of added moles (l) of ethylene oxide is 5 to 15. The liquid cleaning agent for solder flux of the present invention is a compound of general formula () or general formulas () and ().
Although the mixture of compounds may be used as is, it is usually diluted with water to form a transparent and uniform aqueous solution containing 5 to 70% by weight. In addition, when the compounds of general formulas () and () are used together, they should be blended in a ratio (weight ratio) of ():() = 1 to 10:10 to 1, preferably 1 to 5:5 to 1. Therefore, it shows good cleaning power. The liquid cleaning agent of the present invention may also include, if necessary,
Ethylene glycol, to maintain liquid stability
Hydrotropes such as propylene glycol, methanol, ethanol, and propanol can also be blended. Effects of the Invention The liquid cleaning agent of the present invention is aqueous and exhibits excellent cleaning performance for solder flux without the need for fluorocarbon-based solvents, and particularly for cleaning printed wiring boards and printed circuit boards. Extremely effective in removing rosin flux used during soldering. In addition, it has excellent transparency stability and low foaming, so
It is also easy to handle. Hereinafter, the liquid cleaning agent of the present invention will be explained in more detail with reference to Examples, but first, the evaluation method used in the Examples will be described. (1) Transparency of cleaning agent Pour the cleaning agent into a 100ml glass bottle, leave it in a constant temperature room at 25℃ for 24 hours, and visually evaluate the transparency using the following criteria. 〇 is considered a pass. Evaluation criteria 〇: Transparent △: Slightly cloudy ×: Precipitation/two-layer separation (2) Cleanability of flux Solder flux was applied to a glass plate and heated at 200°C.
The board was baked for 15 minutes to obtain a soiled board, and then immersed in a cleaning solution prepared by diluting each cleaning agent 5 times with water at 40°C for 5 minutes. The state of flux dissolution during cleaning is visually determined and evaluated using the following criteria. 〇 or above is considered a pass. Evaluation criteria ◎: Strong dissolving power 〇: Solving power △: Slightly poor dissolving power ×: No dissolving power Example 1 (Preparation of cleaning agent) Each liquid cleaning agent 1 to 13 with the following formulation was prepared. .
In addition, in the description of alkylene oxide addition in the composition, (C 2 H 4 O) 1 (C 3 H 6 O) 2 H means that the blocks were added in that order, and [(C 2 H4O ) 1 /
(C 3 H 6 O) 2 ] indicates random addition. Further, the cleaning agent 11 is a comparative example, and the others are examples.
