Total synthesis metal cutting solution and preparation method thereof

Abstract

The invention discloses a total synthesis metal cutting solution comprising the following components by weight percent: 0.5-1% of pH regulator, 10-20% of antirust agent, 10-15% of mixed hydramine, 5-8% of lubricating agent, 0.1-0.3% of copper alloy corrosion inhibitor, 1-2% of sterilizing agent, 0.1-0.2% of defoaming agent, 0-0.5% of EDTA-4 sodium and the balance of water. The invention provides a preparation method of the total synthesis metal cutting solution. The total synthesis metal cutting solution is good in lubricating performance, and the use effect is superior to that of emulsification solution. By utilizing the total synthesis metal cutting solution, surface smoothness of a workpiece can be improved, a grinding wheel can not be sticked, and abrasion of the grinding wheel is reduced. The total synthesis metal cutting solution has a good sedimentation effect and is less in bubbles, long in service life and excellent in anti-rust property, cooling property, permeability and cleanability. By utilizing the total synthesis metal cutting solution, the service life of the grinding wheel can be effectively prolonged. The total synthesis metal cutting solution is suitable for materials, such as bearing steel, carbon steel and the like, the solution is colorless and transparent, and surface processing conditions are easy to observe. Meanwhile, the total synthesis metal cutting solution does not contain toxic and harmful substances, such as sodium nitrite, phenols and the like and is harmless to environment and operator health.

Description

technical field [0001] The invention relates to a fully synthetic metal cutting fluid, and also relates to a preparation method of the fully synthetic metal cutting fluid, belonging to the field of cutting fluids. Background technique [0002] Fully synthetic cutting fluid has good cooling performance, cleaning performance and visibility performance. At the same time, because it does not contain mineral oil, it has good degradation performance, is not easy to be corrupted and smelly, and has the advantages of long service life; it is in line with the development trend of green cutting fluid. [0003] With the development of metal processing technology, the production efficiency of mechanical processing equipment is increasing day by day, and it is developing in the direction of high speed, large feed rate, high precision and multi-station integration, which puts forward new and higher requirements for the lubrication performance of cutting fluid. [0004] Existing fully ...

Problems solved by technology

However, under the action of high temperature in the processing process, the chlorine-containing lubricating additives will undergo a cracking reaction to generate hydrogen chloride, which will cause corrosion and rust of mechanical equipment and processed workpieces, resulting in a decrease in the anti-rust performance of the processing fluid.

Phosphorus-containing additives are easy to promote the growth of microorganisms, easily cause corruption and odor of cutting fluid, and even cause skin allergies and inflammation of production workers, endangering the health of workers

There are still very few fully synthetic cutting fluids that do not contain chlorine and phosphorus on the market. Their formulas are complicated, the production process is cumbersome, and the antirust performance needs to be further improved.

[0005] To sum up, the existing fully synthetic cutting fluids still have unsatisfactory performance in terms of extreme pressure lubrication performance, cooling performance, rust prevention performance, environmental protection performance, and service life due to the above reasons
