Embodiment 1

[0021] A kind of lubricant, its composition and the amount of each composition of this vegetable oil-based microemulsion cutting fluid can be:

[0022] ① 30g of vegetable oil, 4g of pH regulator, 8g of differential pressure regulator, 12g of emulsifier, 3.5g of corrosion inhibitor, 0.1g of stabilizer, 0.3g of defoamer, 1g of fungicide and 23g of water .

[0023] ② 50g of vegetable oil, 4g of pH regulator, 18g of differential pressure regulator, 22g of emulsifier, 0.1g of corrosion inhibitor, 3g of stabilizer, 0.01g of defoamer, 5g of fungicide and 13g of water.

[0024] ③ 36g of vegetable oil, 11g of pH regulator, 12g of differential pressure regulator, 19g of emulsifier, 1g of corrosion inhibitor, 1.2g of stabilizer, 0.1g of defoamer, 3g of bactericide and 16g of water.

[0025] ④ 44g of vegetable oil, 7g of pH regulator, 15g of differential pressure regulator, 15g of emulsifier, 2g of corrosion inhibitor, 0.8g of stabilizer, 0.2g of defoamer, 2g of fungicide and 20g of wate...

Embodiment 2

[0029] According to an embodiment of the present invention, the specific type of vegetable oil is not particularly limited. According to a specific embodiment of the present invention, the vegetable oil can have a density of 0.85 to 0.93 g / cm 3 , the kinematic viscosity at a temperature of 40 degrees Celsius is 30.0-44.0mm 2 / s vegetable oil,

[0030] According to a specific example of the present invention, the specific type of vegetable oil is not particularly limited, and the vegetable oil in ①~⑥ in embodiment 1 can be at least one of soybean oil, castor oil, peanut oil, palm oil and rapeseed oil, This type of vegetable oil can be used as the basic component for forming water-soluble cutting fluid microemulsion, and the formed system has good lubricity and heat transfer. For example, the vegetable oil may be: ① soybean oil; ② castor oil; ③ peanut oil; ④ palm oil; ⑤ rapeseed oil; ⑥ soybean oil and peanut oil; ⑦ palm oil and rapeseed oil; ; ⑨ soybean oil, castor oil and pea...

Embodiment 3

[0032] According to all embodiments of the present invention, the pH value of the lubricant is not particularly limited, and the pH value of the cutting fluid for the cutting fluid in ①~⑥ in Example 1 can be 7.5~9.3, preferably, the pH value It can be 8.0-9.0. The cutting oil in this pH range can not only inhibit the reproduction of bacteria, but also not cause skin contact and discomfort to the operator due to an excessively high pH value.

Abstract

The invention relates to a lubricant. The vegetable oil based micro-emulsion cutting fluid is prepared from the following components in parts by weight: 30-50 parts of vegetable oil, 4-14 parts of pHregulator, 8-18 parts of differential pressure regulator, 12-22 parts of emulsifier, 0.1-3.5 parts of corrosion inhibitor, 0.1-3 parts of stabilizer, 0.01-0.3 part of defoamer, 1-5 parts of bactericide and 13-23 parts of water. The lubricant has good wear resistance, extreme pressure lubrication performance, rust resistance and biodegradability.

Description

technical field [0001] The invention relates to a lubricant for metal processing. Background technique [0002] With the increasing difficulty of modern manufacturing processes and the continuous emergence of new materials, the requirements for the lubrication performance of cutting fluids are increasing day by day. However, with the wide application of cutting fluid, it is found that cutting fluid is the main source of pollution in metal cutting. Not only will it cause harm to the health of operators when it is used, but the discharge of waste fluid will also pollute the environment. As one of the main raw materials of metal cutting fluid, mineral oil has poor biodegradability and can stay in water and soil for a long time, causing lakes, rivers, oceans and underground rivers to be polluted to varying degrees. Vegetable oil has good biodegradability, non-toxicity, good viscosity-temperature performance, cheap, abundant resources, renewable, and is the best substitute for m...
