Problems solved by technology

[0004] When the emulsification resistance of the grinding oil is low, the viscosity of the emulsified grinding oil becomes larger. When the emulsification is severe, a large amount of foam will be produced from watery fluid to viscous cream. At this time, the fine grinding produced during the grinding process Impurities such as swarf, grinding wheel or oil stone dust and dust do not settle at the bottom and float on the grinding oil, which seriously affects the precision and surface roughness of the workpiece. At the same time, the deterioration of the grinding oil shortens the service life and speeds up the replacement cycle.
[0005] Up to now, there are no relevant reports on improving the demulsibility of grinding oil

Embodiment 1

[0024] Add 12 parts of 5# white oil into the reactor by weight and heat it to 110-120°C to dehydrate it. When the temperature of the 5# white oil in the reactor drops to 80°C, add 3 parts of sodium petroleum sulfonate , 1.2 parts of dodecenylsuccinic acid, 9 parts of boric acid ester and 0.2 part of anti-emulsifier T1001 are added into the reactor together and stirred evenly to make it completely dissolved, and the temperature of the dissolved matter in the reactor is reduced to At 40°C, add 74.6 parts of kerosene into the reaction kettle and stir evenly to obtain a primary grinding oil, and then filter the primary grinding oil when it is lowered to room temperature, and then obtain an anti-emulsification grinding oil.

Embodiment 2

[0026] Add 14 parts of 5# white oil into the reactor by weight and heat it to 110-120°C to dehydrate it. When the temperature of the 5# white oil in the reactor drops to 80°C, add 3.5 parts of sodium petroleum sulfonate , 1.0 parts of dodecenylsuccinic acid, 8 parts of boric acid esters and 0.4 parts of anti-emulsifier T1001 are added into the reaction kettle together and stirred evenly to make it completely dissolved, and the temperature of the dissolved matter in the reaction kettle is lowered to At 40°C, 73.1 parts of kerosene was added into the reaction kettle and stirred evenly to obtain primary grinding oil, which was then filtered when the primary grinding oil was lowered to room temperature, and anti-emulsification grinding oil was obtained after filtration.

Embodiment 3

[0028] Add 16 parts of 5# white oil into the reactor by weight and heat it to 110-120°C to dehydrate it. When the temperature of the 5# white oil in the reactor drops to 80°C, add 4 parts of sodium petroleum sulfonate , 0.8 parts of dodecenylsuccinic acid, 7 parts of boric acid esters and 0.6 parts of anti-emulsifier T1001 are added to the reactor together and stirred evenly to make it completely dissolved, and the temperature of the dissolved matter in the reactor is reduced to At 40°C, 71.6 parts of kerosene were added into the reaction kettle and stirred evenly to obtain primary grinding oil, which was then filtered when the primary grinding oil was lowered to room temperature, and anti-emulsification grinding oil was obtained after filtration.

Abstract

The invention relates to a preparation method of demulsified grinding oil. The preparation method comprises the following steps of: adding 10-20 parts by weight of white oil No.5 into a reaction kettle, and heating to 110-120 DEG C for dehydration; when the temperature of white oil No.5 in the reaction kettle is reduced to 80 DEG C, simultaneously adding 3-5 parts of petroleum sodium sulfonate, 0.5-1.5 parts of dodecenylsuccinic acid, 5-10 parts of borate and 0.2-1 part of demulsifying agent T1001 into the reaction kettle; uniformly stirring to completely dissolve the mixture; when the temperature of a solute in the reaction kettle is reduced to 40 DEG C, adding 70-80 parts of coal oil into the reaction kettle, and uniformly stirring to obtain primary grinding oil; and cooling the primary grinding oil to room temperature, and filtering to obtain the demulsified grinding oil. The demulsified grinding oil has high demulsibility and no emulsification or blistering phenomenon, and is suitable for rough grinding and fine grinding of a workpiece containing a surface active substance and water; and the grinding precision and the surface roughness of the workpiece are improved, and the service life of the demulsified grinding oil is prolonged.

Description

technical field [0001] The invention belongs to the technical field of grinding oil, and in particular relates to a preparation method of an anti-emulsification grinding oil. [0002] Background technique [0003] Grinding oil plays the role of cooling, lubrication, rust prevention and cleaning in the machining process, especially plays a key role in improving the surface shape accuracy, dimensional accuracy and surface roughness of the workpiece. The workpiece must go through rough grinding and fine grinding before grinding, and then it is generally ground directly without cleaning and drying. At this time, some grinding fluid will remain on the surface of the workpiece, and the water and surface active substances can cause the emulsification of the grinding oil. [0004] When the emulsification resistance of the grinding oil is low, the viscosity of the emulsified grinding oil becomes larger. When the emulsification is severe, a large amount of foam will be produced from ...
