The present invention relates to a metal degreasing cleaning agent.
Degreasing and cleaning the metal surface is necessary for pretreatment such as plating and painting, as well as pickling, and is a major factor determining the quality of the finish. Alkaline degreasers are the most common degreasers that not only neutralize and saponify the free fatty acids and acidic components of dirt, but also increase the dispersion of dirt and improve the stability and wettability of the degreaser. Degreasing methods include dipping, spraying, etc.
There is an electrolytic cleaning method that is quick, effective and completely degreases. Cleaning agents for alkaline electrolytic degreasing are known to use alkalis, builders such as oxycarboxylic acids, aminopolycarboxylic acids, chelating agents, etc., but for example, in Japanese Patent Publication No. 51-5824, surfactants are essentially used. is not included, and can only be used in high temperature ranges of 90°C or higher, and the Japanese Patent Publication No. 52-21457 lacks a surfactant and has poor cleaning power, and the Japanese Patent Publication No. 53-6093 requires the use of α-substituted acetylene compounds; The polyoxyethylene alkylphenol used lacks storage stability and stability during the electrolytic cleaning process, and has poor cleaning performance at low temperatures.
Even relatively stable high-molecular-weight products produce a large amount of foam, making them unsuitable for practical use. After repeated research to solve these deficiencies, the present inventors have developed an inorganic alkali builder, an oxycarboxylic acid organic builder, an aminopolycarboxylic acid chelating agent, and an alkyl polyoxyethylene ether type or polyoxyalkylene block of HLB5-16. We have achieved a metal degreasing detergent that contains a copolymer type nonionic surfactant as an essential ingredient. The metal degreasing and cleaning agent of the present invention is most effective when alkaline degreasing is carried out by an electrolytic cleaning method. It is particularly effective in a medium temperature range of about 60 to 70°C, and even in a low temperature range of 50°C or less, and is extremely useful in practice. Furthermore, it exhibits low foaming properties even in an electrolytic bath, and can be used stably for a long period of time. The inorganic alkali builder used in the present invention is
For example, sodium hydroxide, carbonates, phosphates,
Alkaline salts such as silicates and borates, oxycarboxylic acid organic builders, such as gluconic acid, citric acid, malic acid, tartaric acid, lactic acid, glycolic acid, their salts, and aminopolycarboxylic acid chelating agents , for example, nitrilotriacetic acid, ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid,
Examples include glycol ether diamine tetraacetic acid, 1,2 cyclohexane diamine tetraacetic acid, and salts thereof. Alkyl polyoxyethylene ether type nonionic surfactants are composed of saturated or unsaturated alkyl groups having 8 to 22 carbon atoms, and polyoxyalkylene block copolymer type nonionic surfactants are typified by the so-called Pluronic type. be.
These nonionic surfactants are HLB5-16,
If it is less than 5, the stability and cleanability will decrease, and 16
If it is larger, foaming will be significant, causing problems and is not desirable. HLB7-14 are more preferred. The cleaning agent of the present invention has an inorganic alkali builder of 30 to 90%.
parts, preferably 55 to 80 parts, 5 to 40 parts of oxycarboxylic acid organic builder, preferably 10 to 30 parts, 1 to 30 parts of aminopolycarboxylic acid chelating agent, preferably 2 to 15 parts, ionic surfactant is
A good composition is 0.5 to 10 parts, preferably 1 to 5 parts. If any component is outside the above range, the cleaning effect will be poor.In particular, if the specified nonionic surfactant is less than 0.5 parts, the effectiveness at low temperatures will be reduced, and if it is more than 10 parts, foaming will occur, causing practical problems. cause. Any conventional method can be applied to add the cleaning agent of the present invention to an electrolytic degreasing bath and perform electrolytic degreasing. It can also be used in dipping methods, spraying methods, etc. In the present invention, an anionic surfactant or an amphoteric surfactant may be used in combination with the specific nonionic surfactant as long as foaming is not impaired. Example Each formulation in Table 1 was prepared as a metal degreasing cleaning agent. The numbers in the table indicate parts by weight.
