Embodiment 1

[0038] Metal cutting fluid, including the following components by mass percentage:

[0039]

[0040]

[0041] 2. Production process:

[0042] A: Synthetic triethanolamine oleic acid soap

[0043] Add triethanolamine and oleic acid to the reaction kettle according to the specified amount, start stirring, and slowly raise the temperature for 3-5°C / 10 minutes to 80±1°C. The temperature rise rate and the controlled temperature do not produce different reactants, and the lubrication of the finished product And anti-rust performance is different, heat preservation reaction at this temperature for 4 hours, to obtain viscous triethanolamine oleic acid soap, standby.

[0044] B: Add 400 kg of deionized water to the reactor, then add a specified amount of sodium tripolyphosphate into the reactor, start stirring, slowly raise the temperature to 60°C, and add triethanolamine oleic acid soap after the sodium tripolyphosphate is completely dissolved. After the oleic acid soap is com...

Embodiment 2

[0047] Metal cutting fluid, including the following components by mass percentage:

[0048]

[0049]

[0050] The production process of metal cutting fluid comprises the following steps:

[0051] A: Synthetic triethanolamine oleic acid soap

[0052] Add the above-mentioned triethanolamine and oleic acid in mass percentage to the reaction vessel, stir, raise the temperature to 81°C for 3°C / 10 minutes, and keep the temperature for 3 hours to obtain triethanolamine oleic acid soap for later use;

[0053] B: Add 300 kg of deionized water into the reaction vessel, then add the above-mentioned sodium tripolyphosphate in terms of mass percentage, stir, heat up to 55°C, add triethanolamine oleic acid soap after the sodium tripolyphosphate is completely dissolved, wait After the oleic acid soap is completely dissolved, add the above-mentioned other components in terms of mass percentages in the above order, and after all the substances are dissolved, raise the temperature of the...

Embodiment 3

[0056] Metal cutting fluid, including the following components by mass percentage:

[0057]

[0058]

[0059] The production process of metal cutting fluid comprises the following steps:

[0060] A: Synthetic triethanolamine oleic acid soap

[0061] Add the above-mentioned triethanolamine and oleic acid in mass percentages into the reaction vessel, stir, raise the temperature to 79°C for 5°C / 10 minutes, and keep warm for 4.5 hours to obtain triethanolamine oleic acid soap for later use;

[0062] B: Add 500 kg of deionized water to the reaction vessel, then add the above-mentioned sodium tripolyphosphate in terms of mass percentage, stir, heat up to 55°C, and add triethanolamine oleic acid soap after the sodium tripolyphosphate is completely decomposed. After the oleic acid soap is completely dissolved, add the above-mentioned other components in terms of mass percentages in the above order, and after all the substances are dissolved, raise the temperature of the entire ...

Abstract

The invention discloses a metal cutting liquid, the metal cutting liquidcomprises following components in percentages by mass: 1-10% of sodium naphthenate, 5-15% of sodium petroleum sulfonate, 8-25% of 32# engine oil, 1-10% of vegetable oleic acid, 7-12% of triethanolamine, 0.5-5% of cocinic acid triethanolamine, 0.5-5% of 42# chlorinated paraffin, 1-5.0% of OP-10 emulsifier, 1-6% of sodium tripolyphosphate, 0.01-0.4% of bactericide, 0.01-0.3% of anti-foaming agent and the balance of de-ionized water. The cutting liquid can provide buffer action provided by the liquid lubricant, chemical adhesive force and excellent extreme pressure lubricating performance provided by the boundary lubrication during the metal processing by combination of the above effective components; the product does not contain nitrite which has serious damage to human body and has no heavy metal ion which pollutes the environment.

Description

technical field [0001] The invention relates to component processing auxiliary materials, in particular to a metal cutting fluid.
