preparation example Construction

[0049] The preparation method of above-mentioned railway train axle bearing lubricating grease cleaning agent, step is as follows:

[0050] ⑴ Prepare all materials required for preparation in proportion;

[0051] ⑵Put the alcohol amine into the reaction kettle and start stirring;

[0052] (3) Add organic polycarboxylic acid and boric acid into the reaction kettle, stir for 60-120min, and the temperature is 20-80℃, until completely dissolved and reacted;

[0053] (4) Add distilled water to the reaction kettle in turn, and then add the remaining materials in turn, and stir for 20-40 minutes until the mixture is uniform, and the railway train axle bearing lubricating grease cleaning agent is obtained.

Embodiment 1

[0055] A kind of lubricating grease cleaning agent for railway train axle bearings, each material proportioning (mass percentage) is:

[0056] Monoethanolamine 0.2%, Triethanolamine 1.2%, Dodecanedibasic acid 0.5%, Isodecanol Polyoxyethylene Polyoxypropylene Ether 15%, Lauryl Alcohol Polyoxyethylene Polyoxypropylene Ether 5%, 3-Methoxy - 3.5% of 3-methyl-1-butanol, 2% of silicone defoamer, and the balance is distilled water.

[0057] Preparation method: first add monoethanolamine and triethanolamine to the reaction kettle, stir evenly, then add dodecanedibasic acid, stir and react for 60-120min, temperature 20-40°C, until dodecanedibasic acid is completely dissolved and reacted, Then add distilled water, and then add other materials sequentially, stir and mix evenly, and obtain the lubricating grease cleaning agent for railway train axle bearings.

Embodiment 2

[0059] A kind of lubricating grease cleaning agent for railway train axle bearings, the proportion of each material is:

[0060] Monoethanolamine 1%, triethanolamine 12%, terpolymeric acid 2%, boric acid 2%, benzotriazole 0.8%, polysiloxane 1%, isotridecyl alcohol polyoxyethylene polyoxypropylene ether 10%, 3-methoxy-3-methyl-1-butanol 4%, silicone defoamer 1.5%, and the balance is water.

[0061] Preparation method: Add monoethanolamine and triethanolamine to the reaction stirred tank, stir and mix evenly, then add ternary polycarboxylic acid and boric acid, stir for 60-90min, temperature 60-80℃, until the solid is completely dissolved and react, then add distilled water , and then add the remaining materials in turn, stir for 20-40min, and mix evenly to obtain the railway train axle bearing lubricating grease cleaning agent.

Abstract

The invention relates to a lubricating grease cleaning agent for railway train axle bearings. The composition and parts by weight are as follows: 10-25 parts of surfactant, 3-8 parts of co-solvent, 0.1-5 parts of organic polycarboxylic acid, 0-5 parts of boric acid 2 parts, 1-10 parts of alcohol amine, 0-3 parts of non-ferrous metal corrosion inhibitor and anti-rust agent, 0.2-2 parts of defoamer, and distilled water to make up to 100 parts. The cleaning agent of the present invention has extremely strong emulsifying properties for bearing lubricating grease, and can effectively emulsify and dissolve lubricating grease under the condition of 40-80 ° C. After cleaning, there is no white spot residue on the surface of the workpiece, no corrosion to the workpiece, and has certain rust resistance. Meet short-term anti-rust requirements. The cleaning agent has good compatibility with anti-rust oil or grease, and the workpiece after cleaning can be directly dipped in anti-rust oil or coated with grease.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, in particular to a cleaning agent for lubricating grease of railway train axle bearings and a preparation method thereof. Background technique [0002] After a certain period of time or a certain mileage of the railway train, the lubricating grease of the axle bearings will age and the lubricating performance will decline, so regular maintenance is required to clean and remove the aged lubricating grease on the axle bearings, and replace with new lubricating grease Grease to ensure the normal and safe running of the train. [0003] Railway train axle bearing grease has good high temperature stability, mechanical stability, water resistance, extreme pressure and anti-wear properties, and can meet the lubrication requirements under harsh conditions such as high temperature, water spraying, and high load. It has stable physical and chemical properties and is relatively difficult to clean. B...
