preparation example Construction

[0032] The preparation method of the above-mentioned aluminum foil and copper foil no-cleaning oily cutting fluid comprises the following steps:

[0033] (1) Accurately weigh each raw material required for preparing cutting fluid according to the proportioning ratio;

[0034] (2) Add the weighed light mineral oil, long-chain olefin, and polyfatty acid ester into the stirring tank successively, and fully stir for 30min to 90min under normal temperature and pressure to obtain the first mixture solution;

[0035] (3) Mix the antirust agent and alkanol and fully stir at normal temperature and pressure, until the antirust agent is completely dissolved in the alkanol, the stirring can be stopped to obtain the second mixture solution;

[0036] (4) Add the second mixture solution into the first mixture solution, and fully stir at normal temperature and pressure for 1-2 h to obtain the no-cleaning oily cutting fluid for aluminum foil and copper foil.

Abstract

The invention relates to an aluminum foil and copper foil no-clean oily cutting fluid and a preparation method thereof. The invention belongs to the field of lubricating oil for metal processing, and is suitable for cutting aluminum foils, copper foils, tabs and the like in lithium ion batteries, capacitors and other devices. The invention discloses a special no-clean oily cutting fluid for aluminum foils and copper foils, which uses light mineral oil as base oil and comprises long-chain olefin, alkanol, polyfatty acid ester and an antirust agent. According to the invention, the selected base oil is light mineral oil composed of isoparaffin containing side chains and produced by petroleum refining, and has the advantages of small viscosity, easy volatilization and good lubricity. A gas chromatography-mass spectrometry test verifies that the cutting fluid can be completely volatilized within 30 minutes at room temperature after being coated on an aluminum foil, and no residue is left, so that a cleaning process after the aluminum foil is cut is omitted, and the processing cost is greatly saved.

Description

technical field [0001] The invention belongs to the field of lubricating oil for metal processing, and in particular relates to a no-cleaning oily cutting fluid for aluminum foil and copper foil and a preparation method thereof. Background technique [0002] Aluminum foil and copper foil have the characteristics of low density and high lightness, and the specific strength is close to that of high alloy steel. They have good plasticity, electrical conductivity, thermal conductivity and corrosion resistance, etc., and are widely used in industrial life. Especially in the field of new energy batteries and capacitors, most of the current collectors used are aluminum foil and copper foil. [0003] During the cutting process of aluminum foil and copper foil, the machine tool and the aluminum workpiece will rub against each other at high speed and generate a lot of heat, which will increase the processing temperature, reduce the life of the tool, and affect the accuracy of the alum...
