Embodiment 1

[0024] The invention provides an environment-friendly microemulsion cutting fluid, which is composed of narrow fraction naphthenic oil, oily agent, water, antirust agent, pH regulator, surfactant, bactericide and defoamer. The weight percentage of narrow cut naphthenic oil in the cutting fluid is 37.5%. Put the naphthenic oil into the distillation tower and carry out atmospheric and vacuum distillation. The distillate oil is then subjected to hydrofining. During the hydrofinishing process, the reaction pressure of the reactor is 12MPa, the reaction temperature is 320°C, the total space velocity of the oil feed is 0.5 / h, and the reaction hydrogen oil volume ratio is 850. The hydrogen treatment catalyst space velocity is 0.65 / h, relative to the hydrofinishing catalyst space velocity of 1.5 / h, the catalyst in the hydrofinishing process is Mo-W / Al 2 o 3 , to obtain narrow-cut naphthenic oil; then add oily agent A and oily agent B to narrow-cut naphthenic oil, and the weight perce...

Embodiment 2

[0034] The invention provides an environment-friendly microemulsion cutting fluid, which is composed of narrow-fraction naphthenic oil, oily agent, water, antirust agent, pH regulator, surfactant, bactericide and defoamer. The weight percent of the narrow cut naphthenic oil in the cutting fluid is 35%. Put the naphthenic oil into the distillation tower and carry out atmospheric and vacuum distillation. The distillate oil at ~350°C is then subjected to hydrofining. During the hydrofining process, the reaction pressure of the reactor is 10MPa, the reaction temperature is 350°C, the total space velocity of the oil feed is 0.45 / h, and the reaction hydrogen oil volume ratio is 900. Relative to the hydrotreating catalyst space velocity of 0.7 / h, relative to the hydrotreating catalyst space velocity of 1.2 / h, the catalyst in the hydrotreating process is Ni-W-Co / Al 2 o 3 , to obtain narrow cut naphthenic oil. Then add oily agent C and oily agent D to the narrow fraction naphthenic o...

Embodiment 3

[0044] The invention provides an environment-friendly microemulsion cutting fluid, which is composed of narrow-fraction naphthenic oil, oily agent, water, antirust agent, pH regulator, surfactant, bactericide and defoamer. The weight percent of the narrow fraction naphthenic oil in the cutting fluid is 30%, the naphthenic oil is injected into the distillation tower, and subjected to atmospheric and vacuum distillation. The distillate oil at ~350°C is then subjected to hydrofining. During the hydrofinishing process, the reaction pressure of the reactor is 15MPa, the reaction temperature is 330°C, the total space velocity of oil feed is 0.55 / h, and the volume ratio of hydrogen to oil is 930. Relative to the hydrotreating catalyst space velocity of 0.75 / h, relative to the hydrotreating catalyst space velocity of 1.2 / h, the catalyst in the hydrotreating process is Ni-W-Co / Al 2 o 3 , to obtain narrow cut naphthenic oil. Add oily agent A, oily agent B and oily agent C to narrow cu...

Abstract

The invention provides an environment-friendly micro-emulsified cutting fluid. The cutting fluid is prepared from, in percentage by weight, 30%-40% of narrow-fraction naphthenic oil, 15%-20% of an oiliness agent, 15%-20% of water, 3%-5% of an antirust agent, 8%-10% of a pH value regulator, 6%-10% of a surfactant, 6%-8% of a bactericide and 0.1%-0.5% of an antifoaming agent. The cutting fluid is safe, environment-friendly and harmless to the human body.

Description

technical field [0001] The invention belongs to the chemical industry field and relates to a metal processing fluid, in particular to a cutting fluid, in particular to an environment-friendly microemulsion cutting fluid and a preparation method thereof. Background technique [0002] Cutting fluid is an industrial liquid used in metal cutting and grinding to cool and lubricate cutting tools and workpieces. Cutting fluids are divided into two categories: oil-based and water-based. Traditional oil-based cutting fluids have good lubricating performance, but poor cooling and cleaning effects; compared with oil-based cutting fluids, water-based cutting fluids have better cooling and cleaning effects, but also have poor lubricating performance and are prone to deterioration The stink problem. Contents of the invention [0003] The object of the present invention is to provide a kind of environment-friendly microemulsion cutting fluid and preparation method thereof, described th...
