preparation example Construction

[0037] The present invention also provides a kind of preparation method of cutting oil, comprises the following steps:

[0038] a) Putting synthetic ester and vegetable oil into a blending kettle to mix and stir;

[0039] b) Stir the base oil obtained in a) to 60°C to 100°C, add antioxidant, anti-rust agent, extreme pressure anti-wear agent and metal deactivator, stir, then lower the temperature to below 50°C, stop stir;

[0040] The weight percentage of each component is: 20%-40% of synthetic ester, 60%-80% of vegetable oil, 0%-3% of antioxidant, 0%-2% of anti-rust agent, 1%-5% of extreme pressure and anti-wear agent , metal deactivator 0% ~ 1%;

[0041] c) filtering the oil product obtained in b) to obtain a cutting oil product.

Embodiment 1

[0043] a) 30% by weight of synthetic ester and 65.3% of rapeseed oil are mixed and stirred in a blending kettle, wherein the synthetic ester consists of trimethylolpropane triolein, isooctyl stearate, and isooctyl oleate Octyl esters are mixed according to the mass ratio of 3:1:1;

[0044] b) Heat and stir the base oil obtained in a), heat up to 70°C, add 1% of 2,6-di-tert-butyl-p-cresol, 0.6% of rust inhibitor, 3% of trialkyl phosphate and 0.1 % of benzotriazole derivatives, stirred, then cooled to 40°C, and stopped stirring, wherein the rust inhibitor was mixed with dodecenylsuccinic acid semi-fat and ammonium salt type rust inhibitor according to the mass ratio of 4:1 made;

[0045] c) filtering the oil product obtained in b) to obtain a cutting oil product.

Embodiment 2

[0047] a) 25% by weight of synthetic ester and 65.6% of vegetable oil are mixed and stirred in a blending tank, wherein the synthetic ester consists of trimethylolpropane triolein, isooctyl stearate, and isooctyl oleate It is mixed according to the mass ratio of 2:1:1.5; the vegetable oil is prepared by mixing rapeseed oil and oxidized rapeseed oil according to the mass ratio of 8:2;

[0048] b) Heat and stir the base oil obtained in a), heat up to 80°C, add 3% L57 octyl / butyl diphenylamine, 1.2% rust inhibitor, 5% phosphorus nitrogen complex and 0.2% methyl Benzotriazole derivatives, stirring, then cooling down to 45°C, and stopping stirring, wherein the antirust agent is mixed with dodecenylsuccinic acid semifat and ammonium salt type antirust composite agent according to the mass ratio of 3:1 made;

[0049] c) filtering the oil product obtained in b) to obtain a cutting oil product.

Abstract

The invention provides environmentally-friendly efficient atomization cutting oil, which comprises the following components in percentage by weight: 20 to 40 percent of synthetic ester, 60 to 80 percent of vegetable oil, 0 to 3 percent of antioxidant, 0 to 2 percent of anti-rusting agent, 0 to 5 percent of extreme pressure abrasion-resistant agent and 0 to 1 percent of metal passivator. The synthetic ester and the vegetable oil are matched and used base oil, so the cutting oil has the advantages of good lubricating property and biodegradability, resource recycle, no toxicity and the like, has low toxin and low harm to the human body and the ecological environment, meets the requirements of related environmental indexes, has good low-temperature performance and oxidation stability and strong universality, is suitable for metal cutting and processing of most materials, is particularly special cutting oil for modern advanced semi-dry and trace lubrication processing and development, and is mainly used for oil mist lubrication; and the gas and liquid two-phase oil mist can play a role in lubricating, take away a large amount of heat, reduce the consumption of cutting fluid, lower the cost and reduce the discharge of waste solution, and is favorable for environmental protection.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a cutting oil and a preparation method thereof. Background technique [0002] In the process of metal cutting, in order to improve the cutting efficiency, improve the precision of the workpiece and reduce the surface roughness of the workpiece, prolong the service life of the tool and achieve the best economic effect, it is necessary to reduce the friction between the tool and the workpiece, the tool and the chip, Take away the heat generated by material deformation in the cutting zone in time. To achieve these goals, on the one hand, through the development of high-hardness and high-temperature-resistant tool materials and improved tool geometry; Get good economic benefits. [0003] In recent years, with the advancement of manufacturing equipment, new mechanical equipment has been developed in the direction of reducing volume, reducing mass, increasing power, improving efficienc...
