Abstract

The invention relates to a metal processing cutting fluid and specifically relates to a super-high extreme pressure type micro-emulsification cutting fluid and a preparation method thereof. According to the super-high extreme pressure type micro-emulsification cutting fluid, 5# white oil is used as basic oil and is easy to emulsify; emulsification lubricating agents comprise tall oil, oleic diethanolamide, polyoxyethylene(10)nonyl phenyl ether, isononanoicacid, synthetic petroleum sodium sulfonate and zinc naphthenate, and the emulsifying capacity is stronger when the emulsification lubricating agents are matched for using; and more chlorine containing extreme-pressure agent chlorinated paraffin S52 and sulfur containing extreme-pressure agents TPS32 can be emulsified into the basic oil to obtain the super-high extreme pressure type micro-emulsification cutting fluid. According to the super-high extreme pressure type micro-emulsification cutting fluid, emulsification particles are small, and the cutting fluid is stable; simultaneously, a synthetic ester of a fatty acid methyl ester which serves as a lubrication reinforcing agent is added, extreme pressure lubrication requirements of medium-high temperature processing are met, and the super-high extreme pressure type micro-emulsification cutting fluid is suitable for mechanical processing with wider ranges of processing temperatures; and triazine amino-acid esters are used for reinforcing rust protection so that the rust-protecting effects can reach to the best.

Description

technical field [0001] The invention relates to a cutting fluid for metal processing, in particular to an ultra-high extreme pressure microemulsion cutting fluid and a preparation method thereof. Background technique [0002] Metalworking fluids include emulsions, microemulsion cutting fluids and fully synthetic cutting fluids. Among them, emulsified cutting fluid is a traditional product. The emulsion combines the lubricity and rust resistance of oil with the excellent cooling of water, and has good lubricating and cooling properties. Therefore, it is suitable for high-speed and low-pressure metal cutting where a large amount of heat is generated. The processing is very effective, and the price is economical, but the disadvantage of the emulsion is that it is easy to cause bacteria and molds to multiply, and the active ingredients in the emulsion will be chemically decomposed to cause odor and deterioration, short service life and poor stability. Therefore, it is generally ...
