Problems solved by technology

First, the corrosion resistance is poor (the product dilution is 5%, the following is the same, and the number of bacteria after 3 months of use is ≥ 10 7 1), the service life is short, the second is that the defoaming time is long (≥30S), so the cooling performance of the product is poor, which affects the service life of the tool; the third is that the anti-browning performance is poor, and the iron ion content after 3 months of use ( ≥300ppm), thus affecting the stability of the diluent; Fourth, the formula contains formaldehyde, phenol, boron, chlorine, diethanolamine, nitrite and other toxic and harmful substances
Thus limiting the promotion and application of products in the high-end market

Abstract

The invention discloses long-service-life brown-resistant low-foam type water-soluble metal processing oil agent. The long-service-life brown-resistant low-foam type water-soluble metal processing oil agent contains the following components: III-type hydrogenated mineral oil, butanol polyoxypropylene ether, undecylenic dibasic acid, cyclohydroxypropyl oleic acid, tetramethyl hexamethylenediamine, diglycolamine, triisopropanolamine, 2-amino-2-methyl-1-propyl alcohol, benzotriazole, hydrogenated ricinoleic acid, diamine from reaction of polypropylene glycol and epoxypropane, oleic alcohol polyoxyethylene ether, polyether, 2-butyl-1, 2-benzisothiazolin-3-ketone, polyether-modified polysiloxane defoaming agent and water. The product disclosed by the invention has the advantages that the brown resistance is excellent, the service life is long, the low-foaming property is achieved, the defoaming property is ultrastrong and the safety and sanitation quality are high.

Description

technical field [0001] The invention relates to a water-soluble metal processing oil. Background technique [0002] According to incomplete statistics, the poor performance of metal processing oils and the short service life of tools caused by poor performance of metal processing oils all over the world account for about 10% of the annual output value of mechanical processing. In order to minimize the defective rate of processed parts and short tool life in the processing process, metal processing enterprises pay more and more attention to the quality of metal processing fluids. The implementation of national environmental protection laws and regulations has been strengthened year by year, especially the regulations on the discharge of waste water have become more stringent, and the discharge of waste liquid in metal processing enterprises has become the primary concern. Therefore, it is required that the water-soluble metal processing oil used must have excellent corrosion ...
