A kind of microemulsion cutting fluid for aluminum alloy and preparation method thereof

Abstract

The invention discloses a micro-emulsion cutting fluid for aluminum alloy and a preparation method of the micro-emulsion cutting fluid. The micro-emulsion cutting fluid comprises the following raw materials in parts by weight: 12-16 parts of paraffin-based oil, 3-5 parts of star anise oil, 4-7 parts of eucalyptus oil, 5-7 parts of sorbitan fatty acid, 3-4 parts of triethanolamine oleate, 3-4 parts of petroleum sodium sulfonate, 7-8 parts of sorbitan monooleate, 3-4 parts of monoethanolamine, 6-7 parts of zinc sulfate, 4-7 parts of sodium oleate, 6-8 parts of dimethicone, 2-4 parts of sodium molybdate, 4-7 parts of octylphenol polyoxyethylene ether, 4-7 parts of chlorinated paraffin, 4-5 parts of ricinoleic acid, 0.5-1.5 parts of dodecanol, 1.2-1.5 parts of imidazolidinyl urea, 10-15 parts of additives and 15-25 parts of deionized water. The micro-emulsion cutting fluid for aluminum alloy also has the outstanding performances on the aspects of corrosion inhibition property, corrosion resistance, lubrication, rust resistance, defoaming property, service life and the like.

Description

technical field [0001] The invention relates to a cutting fluid for mechanical processing, in particular to a microemulsion cutting fluid for aluminum alloy and a preparation method thereof. Background technique [0002] Cutting fluid (coolant) is an industrial liquid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. Cutting fluid is made of a variety of super functional additives through scientific compound compatibility. It has four main functions of cooling, lubrication, cleaning and rust prevention. Due to the continuous improvement of cutting technology, the continuous emergence of advanced cutting machine tools, and the development of cutting tools and workpiece materials, the variety of cutting fluids has been promoted. It is also required that the cutting fluids used should have good stability and be stable during storage and use. Precipitation or stratification, oil separation, soap separation and aging will occur. It has a c...

Problems solved by technology

Traditional cutting fluids will basically cause certain harm to the human body and the environment. With the advancement of technology, many pollution-free or low-pollution semi-synthetic cutting fluids have been created. and cutting ability and other technical indicators are not good enough, for example: CN201310390530.7 discloses a kind of boron-free, chlorine-free, formaldehyde-free microemulsion cutting fluid and its application. Short question; CN201310490879.8 discloses an environmentally friendly lubricating cutting fluid. The water-based cutting fluid has poor technical indicators such as lubricating performance, extreme pressure and anti-wear performance, anti-rust performance and cutting ability, especially when processing aluminum alloy parts. Corrosion and blackening will occur when
