Water-based metal cutting fluid and machining process thereof

Abstract

The invention discloses water-based metal cutting fluid which is innovatively characterized by consisting of the following components in parts by weight: 12-18 parts of phosphatidic acid, 5-12 parts of absolute ethyl alcohol, 10-20 parts of an emulsifier, 2.2-2.8 parts of dodecenylsuccinic acid, 10-15 parts of fatty alcohol-polyoxyethylene ether, 15-20 parts of coconut oil fatty acid diethanol amide, 8-16 parts of coconut oil amine polyoxyethylene ether, 12-15 parts of a synthetic anti-rusting agent, 1-4 parts of a defoaming agent, 0.5-1.5 parts of benzotriazole and the balance of water. The water-based metal cutting fluid is good in wearing resistance, relatively good in hard water resistance, excellent in electrostatic resistance, chemical stability and microorganism resistance, wide in universality upon multiple cutting modes and workpiece materials, not only good in lubricating property, rusting resistance, antibacterial property and stability and long in service life, but also free of environment pollution and harmless to human bodies, and comprehensively meets cutting requirements of high-difficulty machining.

Description

technical field [0001] The invention relates to a water-based metal cutting fluid, and also relates to a processing technology of the water-based metal cutting fluid, which belongs to the technical field of metal cutting cooling protection. Background technique [0002] At present, there are many kinds of cutting fluids with different functions, but they can be generally summarized into two categories, oil-based cutting fluid and water-based cutting fluid. It will produce smoke and seriously pollute the environment; and the oil-based cutting fluid is easy to catch fire when used, which is unsafe to use and causes serious energy waste, so it can no longer meet the requirements of green manufacturing, and the water-based cutting fluid is due to its cooling effect Good, good fire performance and many other advantages, its development is very fast.

Problems solved by technology

[0002] At present, there are many kinds of cutting fluids with different functions, but they can be generally summarized into two categories, oil-based cutting fluid and water-based cutting fluid. It will produce smoke and seriously pollute the environment; and the oil-based cutting fluid is easy to catch fire when used, which is unsafe to use and causes serious energy waste, so it can no longer meet the requirements of green manufacturing, and the water-based cutting fluid is due to its cooling effect Good, good fire performance and many other advantages, its development is very fast

[0003] In addition, in actual work, the cutting fluid is also required to have a certain anti-rust ability to prevent the environmental medium and corrosive substances such as oil sludge in the residual cutting fluid from corroding the metal. Because the traditional water-based cutting fluid sometimes needs to add a variety of anti-rust Additives, these additives can improve the anti-rust performance of the cutting fluid itself, for example, after compounding different proportions of triethanolamine sebacate and benzotriazole, it can improve the anti-rust performance to a certain extent, but the effect is not good

[0004] In addition, the traditional water-based cutting fluid has obvious hysteresis due to its own rust resistance and stability, as well as environmental protection, which is not conducive to the development of modern cutting technology, and the waste liquid of water-based cutting fluid It is a serious source of pollution. How to minimize the harm of water-based cutting fluid to the environment is an extremely important and difficult problem to solve.
