preparation example Construction

[0036] The preparation method of the above-mentioned aluminum foil and copper foil no-cleaning oily cutting fluid comprises the following steps:

[0037] (1) After mixing trialkylamine and halogenated alkane, add it to solvent acetone or acetonitrile, the molar ratio of reactants is trialkylamine: halogenated alkane)=1:(1.25~1.75), every trialkylamine and solvent The ratio of 0.1mol:100mL. The above solution is reacted under a protective atmosphere of 70-90°C for 24-48h, washed and dried to obtain polyalkylammonium halide; the trialkylamines are triethylamine, tripropylamine, tributylamine, and triamylamine , a kind of trihexylamine; halogenated alkane is bromoethane, bromopropane, bromobutane, bromopentane, bromohexane, iodoethane, iodopropane, iodobutane, iodopentane, iodohexane a kind of;

[0038](2) Add polyalkylammonium halide to deionized water, stir well, then add metal salt solution, the molar ratio of polyalkylammonium halide to metal salt solution is 1:(1.25~1.75),...

Embodiment 1

[0042] Follow the steps below to first synthesize polyalkyl ionic liquids:

[0043] (1) 0.1 mol of tripropylamine and 0.10 mol of bromopropane were mixed and added to 100 mL of acetone, reacted under a nitrogen atmosphere at 70° C. for 24 h, washed and dried to obtain tetrapropylammonium halide;

[0044] (2) Add the tetrapropylammonium halide obtained in step (1) into 100 mL of deionized water, stir evenly, then add 0.125 mol of metal salt solution, stir for 10 h, then add dichloromethane to extract the organic phase, and collect the organic phase by liquid separation , and then repeatedly washed with deionized water for many times, and finally the dichloromethane in the solution was removed by rotary evaporation, and the polyalkyl ionic liquid was obtained by drying;

[0045] (3) Weigh the components of the following proportions respectively:

[0046] Table 1 embodiment 1 material ratio (mass percent)

[0047] Saturated alkanes 10％ Decene 10％ 2-Ethyl-1-...

Embodiment 2

[0050] Follow the steps below to first synthesize polyalkyl ionic liquids:

[0051] (1) 0.1 mol of trihexylamine and 0.125 mol of iodopentane were mixed and added to 100 mL of acetone, reacted under a protective atmosphere of 70°C for 36 h, washed and dried to obtain trihexyl-pentyl-ammonium halide;

[0052] Trihexylamine can be replaced with triethylamine or tributylamine. Iodopentane can be a kind of in other halogenated alkanes such as bromoethane, bromobutane, bromopentane, iodoethane, iodopropane, iodobutane and iodohexane;

[0053] (2) Add the trihexyl-pentyl-ammonium halide obtained in step (1) into 100 mL of deionized water, and stir

[0054] uniformly, then add 0.10moL metal salt solution, stir for 8h, then add dichloromethane to extract the organic phase, collect the organic phase through liquid separation, and then repeatedly wash with deionized water for several times, and finally remove the dichloride in the solution by rotary evaporation Methane, after drying t...

Abstract

The invention discloses a volatile compound cutting fluid for aluminum foils and copper foils and a preparation method thereof, the compound cutting fluid comprises 10-50% of saturated alkane, 10-70% of olefin, 10-75% of Guerbet alcohol and 1-10% of ionic liquid, oxygen atoms on hydroxyl in the Guerbet alcohol have large electronegativity and nucleophilic property, and oxygen atoms on the hydroxyl in the Guerbet alcohol have large electronegativity. The carbon atoms of the olefin are easily coupled with hydroxyl oxygen, and the structure formed by coupling the Guerbet alcohol and the olefin has a structure with a plurality of alkanes, so that the lubricating property which cannot be achieved by independently adding the olefin or independently adding the Guerbet alcohol is synergistically exerted; saturated alkane is light mineral oil with the carbon chain length of C8-C16 and can be volatilized under the condition of natural placement at room temperature, meanwhile, the lubricating property is enhanced, the overall molecular weight of a Guerbet alcohol and olefin coupling structure is increased, the overall flash point of the cutting fluid is increased to 60 DEG C or above, and the cutting fluid is higher in safety and convenient to transport.

Description

Technical field [0001] The invention belongs to the field of lubricants for metal processing, and specifically relates to a volatile compound cutting fluid for aluminum foil and copper foil and a preparation method thereof. Background technique [0002] Aluminum foil and copper foil are widely used in daily life and industrial production, and have good plasticity, electrical conductivity, thermal conductivity and corrosion resistance. In the field of new energy batteries and capacitors, most of the current collectors used are aluminum foil and copper foil. As the demand for power batteries increases, the demand for raw materials such as aluminum foil and copper foil will also increase. During the cutting process of aluminum foil and copper foil, the machine tool tool and the aluminum workpiece will rub at high speed and generate a large amount of heat, which will increase the processing temperature, reduce the tool life, and affect the accuracy of the aluminum workpiece. In...
