Problems solved by technology

However, polyaniline has poor water solubility, and polyaniline is unevenly distributed in the solution, forming a mixed polyaniline cutting fluid. The anti-rust and anti-corrosion oxide film formed on the metal surface is unevenly distributed, which affects the effect of anti-rust and anti-corrosion to a certain extent.

Abstract

The invention relates to a water-based nano polyaniline cutting fluid and a preparation method thereof. The water-based nano polyaniline cutting fluid is characterized in that a component 1 comprises the following components in part by weight: 5 to 10 parts of aniline, 5 to 12 parts of ammonium persulfate, 1 to 5 parts of hydrochloric acid, 3 to 6 parts of dodecylbenzene sulfonic acid, 10 to 16 parts of water soluble phosphate and 30 to 50 parts of water, and is prepared through emulsion polymerization in an ice-water bath for 6 to 8 hours; and a component 2 comprises the following components in part by weight: 20to 30 parts of triethanolamine, 3 to 6 parts of polyethylene glycol, 30 to 50 parts of base oil, 1 to 5 parts of extreme-pressure lubricant, 1 to 5 parts of aqueous anticorrosive agent and 30 to 50 parts of water, and is prepared by adding the components into a reaction kettle, uniformly mixing, heating to the temperature of between 40 and 45DEG C and keeping the temperature for 30 to 50 minutes; and a weight ratio of the component 1 to the component 2 is 1:1-1:2. The nano-scale water-based polyaniline cutting fluid has high water solubility and lubricating property, and the anticorrosive and antirust properties of the cutting fluid are improved.

Description

technical field [0001] The invention relates to the field of cutting fluids in metal processing. In particular, it relates to a water-based nano-polyaniline anti-rust and anti-corrosion cutting fluid and a preparation method thereof. Background technique [0002] Metal cutting fluid is an important supporting material for cutting. In order to reduce the friction between the tool and the workpiece, increase the lubricity and take away the heat generated by friction, it is necessary to inject lubricating coolant between the tool and the metal material to be cut. Therefore In the metal cutting process, choosing a suitable metal cutting fluid can play a good role in lubrication, cooling, cleaning and rust prevention. In addition to the above functions, the cutting fluid should also have good anti-corrosion performance to ensure that the processed parts are clean and free from corrosion. Embroidery, so as to improve the surface accuracy of the processed workpiece, the product si...
