Embodiment 1

[0017] A water-insoluble cutting oil consisting of the following components by weight:

[0018] Base oil 60%

[0019] Grease 19%

[0020] Sulfur-based extreme pressure agent 14%

[0021] Lubricant 6.2%

[0022] Antioxidant 0.3%

[0023] Oil mist suppressant 0.5%.

[0024] The base oil is polybutene (or mineral oil, polyoxyethylene polyoxypropylene ester of dimer linoleic acid, ethylene glycol ester of dimer linoleic acid, pentaerythritol tetraoleate, pentaerythritol tetrastearate).

[0025] The oil ester is vegetable oil (or soybean oil, semi-bran oil, cottonseed oil). The sulfur-based extreme pressure agent is sulfurized isobutylene (or polysulfurized olefin, sulfurized whale oil, sulfurized lard, sulfurized vegetable oil, dinonyl polysulfide, didodecanyl polysulfide). The lubricant is sodium petroleum sulfonate (or calcium petroleum sulfonate, magnesium petroleum sulfonate) with a base value ≥ 400. The antioxidant is 2,6-di-tert-butyl-p-cresol (or 4,4'-methylenebis(2,...

Abstract

The water insoluble cutting oil consists of base oil, grease, sulfide extreme pressure additive, lubricant agent, antioxidant and mist inhibitor mixed together. The product of the present invention excellent extreme pressure lubricating performance, and is suitable for low speed high load cutting to raise service life of cutting tool and ensure excellent machining surface. It is used as common cutting oil for broaching and forming gear, has excellent use effect, no uncomfortable smell and no harmful matter, and is good for environment protection.

Description

Technical field: [0001] The invention relates to a water-insoluble cutting oil for metal broaching and gear forming. Background technique: [0002] In the broaching and gear forming processing of steel, cast iron, aluminum alloy and other metal materials, due to the high requirements on the lubricating performance of the cutting fluid, most of the current non-water-soluble cutting fluid is used, and a large amount of chlorine-based extreme pressure lubrication is added. agent to provide the necessary lubricating properties to ensure machining accuracy and tool life. However, because chlorinated paraffin as a chlorine-based extreme-pressure agent contains carcinogens and easily produces hydrogen chloride gas after incineration, it has been banned in Europe and some developed countries. In the same type of cutting oil produced by some domestic manufacturers, chlorinated paraffin, a substance harmful to human body and environment, is still widely used as extreme pressure lubri...
