Embodiment 1
[0009] A kind of cutting fluid, its raw material comprises following composition by weight component ratio: 35-45% of mineral oil, 5-12% of sodium petroleum sulfonate, 3-6% of lubricant, 2-5% of alkoxy polyether, two 1-4% of ethanolamine, 1-3% of metal corrosion inhibitor, 0.5-2% of defoamer, 0.1-1% of tert-butyl benzoic acid, the rest is water, and the combined pH value is between 8.5-9.5. Further, the metal corrosion inhibitor includes 30-40% of copper corrosion inhibitor, 30-40% of aluminum corrosion inhibitor, and the rest is emulsifier. Further, the copper corrosion inhibitor is benzotriazole, and the aluminum corrosion inhibitor is silicate. Further, the emulsifier is alkanolamine phosphate 6503. The invention has excellent anti-rust performance, and it does not contain harmful ingredients such as chlorine and sodium nitrite, so it is more environmentally friendly and reliable to use, and its antibacterial performance is good, which can effectively prevent the cutting f...
Embodiment 2
[0012] This embodiment is basically the same as Example 1, except that its raw materials include the following composition by weight and component ratio: 40% of mineral oil, 7% of sodium petroleum sulfonate, 4.5% of lubricant, and 3% of alkoxy polyether , diethanolamine 2%, metal corrosion inhibitor 2%, defoamer 1%, tert-butylbenzoic acid 0.6%, the rest is water, and the combined pH value is between 8.5-9.5. Apparently, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation of the present invention. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. However, the obvious changes or changes derived from the essential spirit of the present invention still belong to the protection scope of the presen...
