Cutting fluid

Abstract

The invention discloses a cutting fluid. The cutting fluid is prepared from, by weight, 35-45% of mineral oil, 5-12% of sodium petroleum sulfonate, 3-6% of a lubricant, 2-5% of alkoxy polyether, 1-4%of diethanol amine, 1-3% of a metal corrosion inhibitor, 0.5-2% of a defoaming agent, 0.1-1% of tert-butylbenzoic acid, and the balance of water, and the pH value after combination is 8.5-9.5. The cutting fluid has excellent antirust performance, and is free of harmful ingredients such as chlorine and sodium nitrite, environmentally friendly and reliable to use, good in antibacterial property, capable of effectively preventing the cutting fluid from deteriorating and stinking, low in foam, beneficial to greatly widening the application range, good in lubricating property, capable of greatly reducing the cost, beneficial to the machining precision of the surface of a product, high in applicability and good in practicability.

Description

technical field

[0001] The invention belongs to the technical field of chemical products, and in particular relates to a cutting fluid. Background technique

[0002] When processing ferrous metals and non-ferrous metals in precision machine tools, in the process of cutting, milling, drilling, reaming, and grinding, it is necessary to use cutting fluid for cooling, rust prevention or lubrication, etc. The cutting fluid in the prior art is easy to use Oil mist occurs, which affects the stability of use, and also reduces the service life, and the applicability and practicability are limited. Contents of the invention

[0003] The purpose of the present invention is to provide a cutting fluid with strong applicability.

[0004] The technical solution for realizing the object of the present invention is a kind of cutting fluid, and its raw material comprises the following composition by weight and component ratio: mineral oil 35-45%, petroleum sodium sulfonate 5-12%, lubricant...

Examples

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...
