Embodiment 1

[0016] First prepare low oil mist anti-rust cutting oil: In a 1000L electric heating glass-lined reactor, add 600kg of DB-10 transformer oil, heat to 80°C while stirring, add 60kg of borated glyceride, 45kg of vulcanized fat, and 90kg of soybean oil in sequence and 5 kg of butyl octyl zinc dithiophosphate, after the addition, stop heating and continue to stir for 1 hour to obtain 800 kg of light yellow transparent oil, which is low oil mist antirust cutting oil.

[0017] Then, in a 1000L electric heating glass-lined reactor, add 600kg of low oil mist anti-rust cutting oil, heat to 70°C while stirring, add 70kg of triethanolamine oleic acid soap, 26kg of phosphoric acid ester and N,N-(dibenzo Triazole methylene) laurylamine 10kg, after feeding, stop heating, continue to stir 1 hour, sampling inspection.

Embodiment 2

[0019] Prepare low oil mist antirust cutting oil, same as Example 1.

[0020] Then, in a 1000L electric heating glass-lined reaction kettle, add 600kg of low oil mist anti-rust cutting oil, heat to 60°C while stirring, add 60kg of castor oil polyoxyethylene condensate, 60kg of phosphate ester and N-acetyl benzo Triazole 12kg, after feeding, stop heating and continue to stir for 1 hour, sampling inspection.

Embodiment 3

[0022] Preparation of low oil mist antirust cutting oil: same as Example 1.

[0023] Then, in a 1000L electric heating glass-lined reactor, add 600kg of low oil mist anti-rust cutting oil, heat to 80°C while stirring, add 90kg of triethanolamine ricinoleate sulfonate, 18kg of phosphoric acid ester and benzotriazepam in sequence Azole 3kg, after feeding, stop heating and continue to stir for 1 hour, sampling inspection.

[0024] The cutting fluid prepared by the present invention is used after being diluted with water. It can be diluted with water in proportion (1:5~1:20). The dilution has excellent extreme pressure lubricity and rust resistance. The performance can reach or exceed the relevant indicators of SY1374-77, and the antirust time of a single chip can reach 72 hours, far exceeding the standard. In the processing of some difficult-to-cut materials (such as titanium alloys, stainless steel, etc.) Very low, no irritating odor.

Abstract

The invention relates to a water-soluble low oil mist antirust cutting liquid used for the ferrous and nonferrous metal heavy-duty cutting operation, and the preparation method thereof. The preparation method comprises the following steps: firstly, the low oil mist antirust cutting liquid is prepared; secondly, the low oil mist antirust cutting liquid is added in a reaction vessel as the base oil, and is mixed, heated and warmed up to 60 to 80 DEG C; and then 5 to 15 percent of emulsifying agent, 3 to 10 percent of water solubility phosphate ester and 0.5 to 2 percent of copper / aluminum corrosion inhibitor by the base oil wight are added in sequence; after the completion of feeding, the heating to the reaction vessel is stopped, and the mixed liquor is agitated continuously untill in the uniform and transparent state. The prepared cutting liquid is used after being diluted by adding water, is particularly suitable for metal drilling, threading, gear processing and other heavy-duty cutting operations, and has good extreme pressure lubricating property and anti-rust property. The production cost of the cutting liquid is low, the oil mist is extremely low when in use, and no penetrating odor exists.

Description

technical field [0001] The invention relates to a water-soluble low-oil-mist anti-rust cutting fluid for heavy-duty cutting of black and non-ferrous metals and a preparation method thereof. Background technique [0002] Cutting fluid is essential in metal cutting. At present, ordinary cutting fluids are used for light-load cutting and grinding, but in the processing of difficult-to-cut materials (such as titanium alloys, stainless steel, etc.) and difficult machining processes (such as drilling, tapping), ordinary cutting fluids cannot achieve The ideal requirement is replaced by heavy-duty caustic water-soluble cutting fluid or cutting oil, but the biggest disadvantage of cutting oil is that it is extremely expensive to use and the production environment is poor. At present, the general heavy-duty water-soluble cutting fluids are deficient in terms of rust resistance, oil mist, and odor during use.
