Embodiment 1

[0022] Embodiment 1, base oil vacuum distillation cutting treatment.

[0023] The distillation temperature is less than 220°C, the vacuum degree is less than negative 0.95Pa, about 10-15% light oil is cut out, the flash point (closed) of the remaining oil is increased by more than 150°C, and the kinematic viscosity at 40°C is controlled at (5.5-6.5 mm2 / s), and then the remaining oil is deodorized and decolorized by adsorption of activated clay at 90°C, and filtered by a filter press to become a special magnetic cutting oil as a base oil.

Embodiment 2

[0024] Embodiment 2, compared with embodiment 1, the difference is that the percentages of some components are different, and the rest are the same.

[0025] Pure rapeseed oil 4%, epoxidized soybean oil 2%, olive oil 2%, deesterified lard 2%, (T501) di-tert-butyl-p-cresol 0.5%, (T551) benzotriazole derivatives 0.2%.

Embodiment 3

[0026] Embodiment 3, compared with embodiment 1, the difference is that the percentages of some components are different, and the rest are the same.

[0027] 75% of base oil, 0.3% of antistatic agent, 3% of oleic acid ester, 5% of alcohol amine ester, 10.7% of complex agent in Example 2, 2% of S additive, 3% of P additive, and 1% of CL additive.

[0028] The compounding reaction process is as follows: first put the base oil into the reaction blending kettle, heat and stir to 65-70°C, add various additives, stir and dissolve until uniform and transparent, then cool down to about 60°C, then add extreme pressure additives to continue After stirring the oil to be uniform and transparent, keep it warm and stir for 45 minutes. When the temperature of the oil is .50°C, filter the finished product with 5um ultra-fine filter while it is hot.

Abstract

The invention relates to special oil products for petrochemical products, in particular to special magnetic cutting oil and a preparation method thereof. The special magnetic cutting oil is suitable for lubricating, cooling, anti-attrition, and reducing attrition of tools in various processing methods of cutting, sawing, grinding, drilling, and the like of hard materials of non-metallic hard special magnetism, rock quartz, diamond, silicon crystal, and the like, and comprises the following components in percentage content by weight: 75% of base oil, 10% of animal and vegetable oil, 6% of extreme-pressure additive, 0.7% of anti-oxidant, 0.3% of static inhibitor, and 8% of oiliness additive. The special magnetic cutting oil has excellent lubricity and cooling performance, meets the requirement of enough lubricating and cooling performance of a tool and a processing workpiece, prolongs the service life of the tool, has favorable penetrating quality, ensures the surface of the processing piece to be bright, clean and smooth, and ensures lubricating and cooling during processing of non-metallic hard materials.

Description

technical field [0001] The invention relates to a special oil product for petrochemical products, especially a kind of lubricating oil suitable for cutting, sawing, grinding, drilling and other hard materials such as non-metallic hard special magnetic, crystal stone, diamond, silicon crystal, etc. , Cooling, reducing wear, reducing tool wear special magnetic cutting oil and its preparation method. Background technique [0002] With the rapid development of national economy and national defense science and technology, the mechanical processing industry is rapidly improving to high speed and precision, and the cutting oil (fluid) for processing hard materials such as hard special magnetism, crystal stone, diamond, and silicon crystal is getting higher and higher. requirements. At present, the metal cutting oil and water-based cutting fluid provided by the society have been unable to meet the cooling and lubrication requirements for non-metallic hard materials, especially for ...
