Preparation method of full-synthetic type cutting fluid

Abstract

The invention discloses a preparation method of a full-synthetic type cutting fluid. The preparation method of the full-synthetic type cutting fluid comprises the following operation steps of (1) after mixing boric acid and triethanolamine, heating, carrying out insulation treatment to obtain boric acid triethanolamine; (2) adding samarium chloride and lanthanum chloride into water, then adding naphthenic acid into a mixture, uniformly mixing and stirring, rising the temperature of a mixture to 88 to 92 DEG C, carrying out insulation treatment for 3 to 4 hours to obtain a naphthenic acid rareearth mixture; (3) uniformly mixing boric acid triethanolamine, the naphthenic acid rare earth mixture, sodium hydrosulfite, polyglycerol monosterate, polyoxyethylene sorbitan monolaurate, calcium stearoyl lactylate and deionized water, carrying out ultrasonic treatment for 20 to 30 min to obtain the full-synthetic type cutting fluid. The preparation method of the full-synthetic type cutting fluidprovided by the invention is green, environmentally-friendly and low in cost; the prepared full-synthetic type cutting fluid has excellent extreme pressure lubrication performance and antirust property, and can effectively avoid the occurrence of the phenomenon of discoloration of non-ferrous metal.

Description

technical field [0001] The invention belongs to the technical field of cutting fluids, and in particular relates to a preparation method of fully synthetic cutting fluids. Background technique [0002] Non-ferrous alloy is an alloy composed of a non-ferrous metal as the base (usually more than 50%) and adding one or several other elements. Non-ferrous metals usually refer to all metals except iron (and sometimes manganese and chromium) and iron-based alloys. Non-ferrous metals can be divided into heavy metals (such as copper, lead, zinc), light metals (such as aluminum, magnesium), precious metals (such as gold , silver, platinum) and rare metals (such as tungsten, molybdenum, germanium, lithium, lanthanum, uranium). With the continuous development and application of new non-ferrous metal materials and processing technology, some difficult-to-machine materials, such as non-ferrous alloy materials such as nickel alloys, titanium alloys and aviation aluminum alloys, the heavy...

AI Technical Summary

Problems solved by technology

Cutting fluid generally has three types: emulsified type, semi-synthetic type (microemulsion type) and fully synthetic type. Emulsified type cutting fluid has good lubricating performance, but poor cooling performance, easy to deteriorate, and serious pollution, high post-processing cost; semi-synthetic type The lubrication performance of cutting fluid is between emulsified type and fully synthetic type, and there is also pollution; fully synthetic cutting fluid has low cost, long shelf life, excellent cooling and cleaning performance, good visibility, but extreme pressure lubrication performance and rust prevention Poor performance, may also cause discoloration of non-ferrous metals
