Problems solved by technology

Because the parts and finished products of the bearing are covered with a lot of grease and dirt inside and on the surface during machining, heat treatment and assembly, if not cleaned, it will affect the various processes and product quality
[0003] At present, the traditional method in the bearing industry is to use petroleum solvents, kerosene and gasoline to clean the bearings. This not only has the problem of waste of petroleum raw materials and environmental pollution, but also has a low ignition point of petroleum solvents, which can easily cause fires. The skin is also prone to damage

Embodiment 1

[0026] Present embodiment is example with preparing 100kg cleaning agent, and its preparation process is as follows:

[0027] Take by weighing the consumption of each raw material reagent by raw material formula, the consumption of each raw material reagent is as follows:

[0028] Surfactant ① sodium dodecylbenzene sulfonate 10kg

[0029] ②Nonylphenol polyoxyethylene ether 5kg

[0030] Corrosion inhibitor ① Hexatropine 2kg

[0031] ② Benzotriazole 0.5kg

[0032] Defoamer Methylsiloxane 3.0kg

[0033] Chelating agent Sodium edetate 1kg

[0034] Deionized water 78.5kg

[0035] First add deionized water into the stirring tank, then add surfactants, corrosion inhibitors, chelating agents, and defoamers into the stirring tank in sequence, stir while adding materials, and stir for 5 minutes after all the addition is completed. After being filled evenly, a special cleaning agent for bearings that replaces kerosene can be obtained.

Embodiment 2

[0037] Present embodiment is example with preparing 100kg cleaning agent, and its preparation process is as follows:

[0038] Take by weighing the consumption of each raw material reagent by raw material formula, the consumption of each raw material reagent is as follows:

[0039] Surfactant ① Alkyl ether phosphate triethanolamine salt 8kg

[0040] ②Nonylphenol polyoxyethylene ether 2kg

[0041] Corrosion inhibitor ① Hexatropine 2kg

[0042] ② Benzotriazole 0.5kg

[0043] Defoamer Methylsiloxane 3.0kg

[0044] Chelating agent Sodium edetate 1kg

[0045] Deionized water 80.5kg

[0046] First add deionized water into the stirring tank, then add surfactants, corrosion inhibitors, chelating agents, and defoamers into the stirring tank in sequence, stir while adding materials, and stir for 5 minutes after all the addition is completed. After being filled evenly, a special cleaning agent for bearings that replaces kerosene can be obtained.

Abstract

The invention discloses an axle bearing single-purpose cleaning agent to displace coal oil and preparing method in industrial cleaning agent technical domain, which comprises the following steps: allocating 5-15% surfactant, 0.5-5.0% inhibitor, 1- 5.0% defoamer, 1-5.0% chelant and water as raw material; putting deionized water into stirring autoclave; adding surfactant, inhibitor, chelant and defoamer into stirring autoclave sequentially; stirring at the same time; stirring five minutes until the all are finished; mixing evenly and completely; getting the product. It's a water-based cleaning agent, which possesses effects of cleanliness, anti-rust, low-foam and environmental protection.

Description

technical field [0001] The invention relates to a special bearing cleaning agent replacing kerosene and a preparation method thereof, belonging to the technical field of industrial cleaning agents. Background technique [0002] Bearing cleaning is an important process to ensure the quality of bearing products. Because the parts and finished products of the bearing are covered with a lot of grease and dirt inside and on the surface during machining, heat treatment and assembly, if they are not cleaned, it will affect the various processes and product quality. [0003] At present, the traditional method in the bearing industry is to use petroleum solvents, kerosene and gasoline to clean the bearings. This not only has the problem of waste of petroleum raw materials and environmental pollution, but also has a low ignition point of petroleum solvents, which can easily cause fires. The skin is also vulnerable. Therefore, research and development of a water-based special cleanin...
