Abstract

The invention discloses rust-proof emulsified type metal cutting fluid which is prepared from, by weight, 40-50% of base oil, 5-15% of an anionic surfactant, 0.5-2.0% of a nonionic surfactant, 3-5% of a black metal inhibitor, 5-10% of a coupling agent, 0.5-1.0% of a copper alloy inhibiter, 3-10% of a lubricating agent, 1-2% of a bactericide, 0.2-0.5% of a defoaming agent and the balance water.The black metal inhibitor is added into the emulsified type cutting fluid formula, excellent interprocess dust-proof protection is provided, and it is ensured that corrosion is avoided before a machined workpiece is transferred to the next process; by adding the lubricating agent and the compound of the anionic and nonionic surfactants, the excellent lubricating performance and corrosion resistance and the outstanding hard water resistance are obtained; the working fluid is long in service life, contains no nitrite, phenols and other toxic and harmful substance, and is beneficial to health of environmental protection and workers.

Description

technical field [0001] The invention relates to the technical field of metal cutting fluid, in particular to an antirust emulsified metal cutting fluid. Background technique [0002] Cutting fluid is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, cutting and grinding. It is made of a variety of super functional additives through scientific compounding. agent. There are many functions of cutting fluid, among which lubrication, rust prevention, cleaning and cooling are the most important functions, so it can prolong the service life of cutting tools, prevent metal parts from rusting, take away the heat generated during processing, and effectively clean parts and cutting tools Chips and dust particles on the surface can improve processing quality and increase production efficiency. [0003] According to the composition, cutting fluid is usually divided into two categories: oil-based fluid and water-based fluid. The cost of ...
