Problems solved by technology

However, the ordinary water-based cleaning agent added with the above-mentioned anti-rust agent, its anti-rust time is difficult to reach one month, which cannot meet the requirements for anti-rust time in the process of bearing processing and turnover.
In addition, if the concentration of antirust agent added to the water-based cleaning agent is high, there will be more residue on the surface of the cleaned bearing, and the measurement result of the vibration value will be higher
Therefore, water-based cleaning agents are often difficult to meet the requirements of precision bearings for cleaning, anti-rust and vibration values.

Embodiment 1

[0028] The electrolyte sodium carbonate is first dissolved in pure water, and the concentration of the prepared sodium carbonate is ≥10%. Add this sodium carbonate solution into the electrolytic cell with negative and positive electrodes and ion diaphragm, connect the DC power supply, make the water undergo electrolysis reaction, and control the pH value of the generated electrolyzed water to be 11.5-13.0.

[0029] Take 98.6kg of the above strong alkaline electrolyzed water, 0.4kg of sodium oleate, 0.8kg of sodium undecyl dibasic acid, and 0.2kg of sodium citrate, dissolve and mix the above materials evenly to obtain the product.

Embodiment 2

[0031] The electrolyte potassium carbonate is firstly dissolved in pure water, and the concentration of the prepared potassium carbonate is ≥15%. Add the potassium carbonate solution into an electrolytic cell with negative and positive electrodes and an ion diaphragm, connect a direct current power supply, make the water electrolyze, and control the pH value of the generated electrolyzed water to be 12.0-13.5.

[0032] Take 99.2kg of the strongly alkaline electrolyzed water, 0.35kg of potassium oleate, 0.3kg of potassium undecyl dibasic acid, and 0.15kg of potassium citrate, dissolve and mix the above materials evenly to obtain the product.

Embodiment 3

[0034] Get 98.8kg of strongly alkaline electrolyzed water made in Example 2, 0.5kg of potassium oleate, 0.6kg of potassium undecyl dibasic acid, and 0.1kg of potassium citrate, and dissolve and mix the above materials to obtain the product.

Abstract

The invention relates to a water-based cleaning agent with an antirust function special for bearings, which is prepared by first electrolyzing water into strong alkaline electrolyzed water, then utilizing the strong alkaline electrolyzed water to serve as a raw material, and adding oleate, citrate and undecyl dibasic acid salt into the strong alkaline electrolyzed water. The weight percentage of components in the bearing cleaning agent is: 98.5%-99.3% of strong alkaline electrolyzed water, 0.3%-0.6% of oleate, 0.1%-0.4% of citrate and 0.2%-1.0% of undecyl dibasic acid salt. The cleaning agent can be used for cleaning and interprocess rust prevention of bearings, accessories of the bearings or other black metals of steel or cast iron and the like.

Description

technical field [0001] This product belongs to the metal cleaning agent in the field of fine chemical industry. It is mainly used for cleaning and rust prevention of parts and finished products in the bearing processing process, and can also be used for cleaning and rust prevention of other metal processing parts. Background technique [0002] During the bearing production process, metal powder, abrasive powder, grinding fluid, ultra-essential oil, oil stains brought in during the operation of the equipment, and dust in the air during the storage and handling of the workpiece remain on the surface of the parts and finished products during the bearing production process. At present, most bearings are cleaned with organic cleaning agents such as kerosene or carbonized water. The cleaning mechanism of organic cleaning agents such as kerosene or carbonized water is to dissolve the oily dirt on the surface of the workpiece and wash away various solid powders. When the amount of b...
