preparation example Construction

[0017] For the preparation method of the water-soluble polyaniline of the present invention, refer to the Chinese patent application number 200410011266.2, the number-average molecular weight of the polyether polyol is preferably 800-1000; the number-average molecular weight of the polyacrylamide is preferably 700,000-950,000.

[0018] The preparation method of polyaniline cutting fluid of the present invention comprises as follows:

[0019] Add water into the reaction kettle, raise the temperature to 40-80°C, add water-soluble polyaniline into the reaction kettle, stir until the water-soluble polyaniline is fully dissolved, and then add polyacrylamide, polyether polyol, three The polyaniline cutting fluid is obtained after ethanolamine, di-n-butyl phosphite, boric acid and emulsified silicone oil are fully stirred and mixed evenly.

[0020] The polyaniline cutting fluid of the present invention is suitable for various metal cutting, grinding, drilling and other processing te...

Embodiment 1

[0023] Add 53 parts of water into the reaction kettle, raise the temperature to 40°C, add 10 parts of water-soluble polyaniline to the reaction kettle, stir until the water-soluble polyaniline is fully dissolved, and then add polyaniline with a number average molecular weight of 700,000 to the reaction kettle 10 parts of polyacrylamide, 2 parts of polyether polyol with a number-average molecular weight of 800, 10 parts of triethanolamine, 5 parts of di-n-butyl phosphite, 5 parts of boric acid, 5 parts of emulsified silicone oil, stirring while feeding, after mixing evenly That is, the polyaniline cutting fluid was obtained.

[0024] The workpiece was treated with the polyaniline cutting fluid prepared in Example 1 of the present invention, and the experimental results showed that the treated workpiece was not rusted after being soaked in seawater for 60 days, and the cutting production line was free from rancidity without changing the bath fluid for 120 days.

Embodiment 2

[0026] Add 53 parts of water to the reaction kettle, raise the temperature to 55°C, add 10 parts of water-soluble polyaniline to the reaction kettle, stir until the water-soluble polyaniline is fully dissolved, and then add polyaniline with a number average molecular weight of 820,000 to the reaction kettle 10 parts of polyacrylamide, 2 parts of polyether polyol with a number-average molecular weight of 920, 10 parts of triethanolamine, 5 parts of di-n-butyl phosphite, 5 parts of boric acid, 5 parts of emulsified silicone oil, stirring while feeding, after mixing evenly That is, the polyaniline cutting fluid was obtained.

Abstract

The invention provides polyaniline cutting fluid, belongs to the technical field of metal machining, and solves the problems of poor lubricating property and extreme pressure resistance of the existing polyaniline cutting fluid. The polyaniline cutting fluid comprises the following components by weight percent of 5-15 parts of water-soluble polyaniline, 10-15 parts of polyacrylamide, 2-4 parts of polyether polyol, 10-15 parts of triethanolamine, 5-10 parts of dibutyl phosphate, 5-10 parts of boric acid, 5-10 parts of silicone emulsion, and the balance of water. The polyaniline cutting fluid disclosed by the invention has good lubricating property and extreme pressure resistance besides good corrosion resistance and mildew-proof performance; and the maximal anti-bite load value is greater than 70kg.

Description

technical field [0001] The invention belongs to the technical field of metal cutting, and in particular relates to a polyaniline cutting fluid. Background technique [0002] Synthetic water-based cutting fluid has good cooling and cleaning functions, and is popular with users because it does not contain oil. In order to improve the ability of anti-rust and anti-mildew, the patent CN1778879A introduced a polyaniline anti-rust metal cutting fluid. For the first time, polyaniline was used in the field of cutting fluids, and achieved results in anti-rust and anti-mildew, but the synthetic type The lubricity and extreme pressure resistance of water-based cutting fluid are not good. Contents of the invention [0003] The object of the present invention is to provide a kind of polyaniline cutting fluid, this polyaniline cutting fluid not only has good anti-corrosion and anti-mildew properties, meanwhile, the polyaniline cutting fluid of the present invention has good lubricity a...
