example 1

[0030] S1: Take 10kg of base oil 150N by weight percentage and add it to the stirring tank, then add 1kg of high molecular weight polymer ester sulfide extreme pressure agent, 2kg of high alkali value calcium sulfonate, and 0.2kg of di-tert-butyl p-formaldehyde phenol.

[0031] S2: Turn on the agitator with a rotation speed of about 60r / min, and start the heating function at the same time. When the temperature of the material rises to 70~100°C, stir at a constant temperature for 30 minutes, and then turn off the heating function.

[0032] S3: Weigh 86.8kg of base oil 150N into the stirring tank, and continue stirring for 30 minutes to obtain 100kg of metalworking fluid.

example 2

[0034] S1: Weigh 10kg of base oil 150N into the stirring tank, add 2kg of high-molecular polymer ester sulfide extreme pressure agent, 2kg of high-molecular-weight ester polymer, and 0.2kg of di-tert-butyl-p-cresol.

[0035] S2: Turn on the stirrer at 60r / min, and start the heating function at the same time. When the temperature of the material rises to 70~100°C, stir at a constant temperature for 30min, and then turn off the heating function.

[0036] S3: Weigh 85.8kg of base oil 150N and put it into a stirring tank, and stir at room temperature for 30 minutes to obtain a metalworking fluid.

[0037] During the use of this metalworking fluid, there is no reaction on the production line and there are problems of irritating smell or skin irritation. For high-speed cutting aluminum alloy, stainless steel, and brass products, the life of the tool and the yield of the product can reach the same level as the purchased product. equivalent effect of metalworking fluids.

example 3

[0039] S1: Weigh 10kg of base oil 150N into the stirring tank, add 3kg of high-molecular polymer ester sulfide extreme pressure agent, 4kg of high-molecular-weight ester polymer, 0.2kg of di-tert-butyl-p-cresol, 0.2kg high molecular weight mixed esters.

[0040] S2: Turn on the stirrer at 60r / min, and start the heating function at the same time. When the temperature of the material rises to 70~100°C, stir at a constant temperature for 30min, and then turn off the heating function.

[0041] S3: Weigh 82.6kg of base oil 150N and put it into a stirring tank, then add all the concentrated solution prepared above, and stir at room temperature for 30 minutes to obtain 100kg of metalworking fluid.

Abstract

The invention provides a multifunctional oil cutting fluid for metal finish machining. The multifunctional oil cutting fluid comprises the following raw materials by weight percentage: 75-98% of baseoil; 1-8% of an extreme pressure agent; 1-10% of a lubricant; and 0.1-7% of a compound agent. The base oil is class II hydrogenated oil. The extreme pressure agent is the sulfur-containing extreme pressure agent and high alkali value calcium petroleum sulfonate, wherein the sulfur-containing extreme pressure agent contains 10-30% of sulfur, has excellent anti-extreme pressure properties, and has negligible smell compared with that of sulfurized olefin, sulfur is inactive at a temperature of 100DEG C or below, is non-corrosive to nonferrous metals and black metals, and at the same time the additive also has good lubrication performance. High alkali value calcium petroleum sulfonate can provide very high extreme pressure resistance, and also has certain detergency.

Description

technical field [0001] The invention relates to the technical field of metal finishing. In particular, the invention relates to a multifunctional oily cutting fluid for metal high-speed finishing, which can be used for high-speed and high-precision milling of various metal materials such as aluminum alloys, copper alloys, and steels. Background technique [0002] Alloy metals are the most commonly used, such as aluminum alloys, stainless steel, copper alloys and other materials are widely used in notebook computers, smart phones, watches and other electronic products industries. In this field, many metal parts are directly cut and formed by CNC precision machine tools, and then undergo surface treatments such as sandblasting, polishing, anodizing, PVD coating, and electroplating. Cutting fluid is used in CNC machining, and the cutting fluid mainly acts as lubrication and cooling. At present, there are two types of commonly used cutting fluids: oily and water-based. Althou...
