Cooling solution for machining

Abstract

The invention discloses a cooling solution for machining. The cooling solution comprises, by weight, 100 parts of plant oil, 15-25 parts of triethanolamine, 3-7 parts of potassium hydroxide, 4-8 parts of sodium benzoate, 3-6 parts of tert-butylhydroquinone, 0.5-1.5 parts of fluorboric acid, 0.5-1.5 parts of a methanol-isopropanol mixture, 5-10 parts of sodium chloride, 0.1-1 part of an antirust agent and 0.1-1 part of an antiwear lubricant. The plant oil is conjugated triene-containing tung oil. The antiwear lubricant is dry molybdenum disulfide. The antirust agent is a silane coupling antirust agent. The cooling solution for machining has good environmental protection performances, skid resistance and good antirust performances, does not contain harmful substances such as nitrite and heavy metals, can be recycled for 6 months, does not go bad and produce odor, does not corrode a machine tool and a workpiece, does not produce foam and odor, is convenient for product cutting, does not produce rust in work for 15 days, has a good antirust function, is convenient for use and can be stored for two years or more.

Description

technical field [0001] The invention relates to the field of machining, in particular to a cooling liquid for machining. Background technique [0002] In mechanical production, work that requires cutting is often encountered, such as sawing machine using band saw cutting, lathe turning cutting, etc. During the cutting process, because the tool is in close and long-lasting contact with the workpiece, high heat will be generated during the cutting process. The cutting tool and The friction generated between the workpieces will also cause a certain wear and tear on the cutting tool, so the cutting process consumes a lot of cutting tools. Generally, the cutting fluid should meet the four purposes of cooling, lubrication, cleaning and rust prevention. Most of the existing enterprises are still using nitrous acid Sodium is used as anti-rust agent, sodium nitrite is added with water, the cooling performance is excellent, and the anti-rust is also possible, but it will cause white s...

[0002] In mechanical production, work that requires cutting is often encountered, such as sawing machine using band saw cutting, lathe turning cutting, etc. During the cutting process, because the tool is in close and long-lasting contact with the workpiece, high heat will be generated during the cutting process. The cutting tool and The friction generated between the workpieces will also cause a certain wear and tear on the cutting tool, so the cutting process consumes a lot of cutting tools. Generally, the cutting fluid should meet the four purposes of cooling, lubrication, cleaning and rust prevention. Most of the existing enterprises are still using nitrous acid Sodium is used as anti-rust agent, sodium nitrite is added with water, the cooling performance is excellent, and the anti-rust is also possible, but it will cause white spots on the surface of the workpiece after processing, and sodium nitrite is carcinogenic, which will cause damage to the operator's body
