Problems solved by technology

In automatic large-scale production and processing, a high cooling rate is usually required. High pressure and high flow rate are conducive to chip breaking and can quickly flush the chips away from the chip parts, but this will cause foam problems. A large amount of foam will make the liquid volume sign

Abstract

The invention relates to a cutting liquid for metal processing and a preparation method of the cutting liquid, and in particular relates to a micro emulsion type cutting liquid with high lubrication, low foam and long service life. The cutting liquid comprises the following components in percentage by weight: 25-35% of base oil. 10-20% of alkali holding agent, 5-10% of anionic surfactant, 5-8% of anti-rusting agent, 3-4% of coupling agent, 0.5-1% of emulsifier, 5-7% of extreme pressure agent, 0.1-0.2% of defoaming agent, 0.2-0.5% of bactericide and the balance of water. The preparation method of the micro emulsion type cutting liquid with high lubrication, low foam and long service life comprises the following steps: in a system of base oil, adding the alkali holding agent, the anionic surfactant, the anti-rusting agent, the coupling agent, the emulsifier, the extreme pressure agent, the defoaming agent, the bactericide and the water, and uniformly mixing and stirring. Compared with the prior art, the cutting liquid is not only good in lubrication property, improves the processing precision and surface smoothness and reduces the source for generating foam, but also is long in service life and convenient to manage.

Description

[technical field] [0001] The invention relates to a cutting fluid for metal processing and a preparation method thereof, in particular to a microemulsion cutting fluid with high lubrication, low foam and long service life. [Background technique] [0002] In machining, water-based metal cutting fluid is currently widely used. Among them, microemulsion (semi-synthetic) cutting fluid can not only provide good lubrication like emulsion, but also have good cooling and stability like fully synthetic cutting fluid, so it is widely used. In automatic large-scale production and processing, a high cooling rate is usually required. High pressure and high flow rate are conducive to chip breaking and can quickly flush the chips away from the chip parts, but this will cause foam problems. A large amount of foam will make the liquid volume significantly Swelling and odor are more volatile and form aerosol, which cannot make the lubrication function work normally. And because the inside o...
