preparation example Construction

[0020] A preparation method of lubricant, comprising the steps of:

[0021] S1. Heat the base oil. When the oil temperature reaches 80-100°C, add stearic acid and an emulsifier with an HLB value of <6 and mix evenly to obtain an oil phase for later use;

[0022] S2. Mix water and polyhydric alcohol evenly to obtain water phase A. After fully stirring, slowly add water phase A to the oil phase and continue stirring for emulsification to obtain emulsion a for later use;

[0023] S3. Mix the polyol, the emulsifier with an HLB value>15, and water evenly to obtain an aqueous phase B, add the emulsion a obtained in step 2 into the aqueous phase B under stirring, and continue to stir for emulsification to obtain an emulsion b, which is set aside;

[0024] S4. Potassium hydroxide is mixed with water to obtain a potassium hydroxide solution; then the emulsion b obtained in step 3 is added to the potassium hydroxide solution under stirring for saponification reaction to obtain a soap-ba...

Embodiment 1

[0028] First heat the base oil, when the oil temperature reaches 80-100°C, add stearic acid and an emulsifier with an HLB value 15, and water to obtain water phase B, and step 2 Add the obtained emulsion a into the water phase B under stirring and continue to stir for emulsification to obtain emulsion b for later use, then mix potassium hydroxide with water to obtain a potassium hydroxide solution; then add the emulsion b obtained in step 3 under stirring Carry out saponification reaction in potassium hydroxide solution to obtain soap-based lubricants, and then carry out inspection and testing on each batch of products to check whether the specific gravity, pH value and other indicators of the products meet the quality requirements, and do a sample test for each batch, and it is qualified The finished product is directly discharged through gravity flow, and finally the qualified product enters the automatic packaging machine through the feeding pump from the outlet of the open...

Embodiment 2

[0030] In embodiment one, add following operation:

[0031] When mixing stearic acid and emulsifier in step 1, the rotating speed of the stirrer is kept at 1000~1200rpm, and the stirring is carried out for 20-30min.

[0032] First heat the base oil, when the oil temperature reaches 80-100°C, add stearic acid and an emulsifier with an HLB value 15, and water to obtain water phase B, and step 2 Add the obtained emulsion a into the water phase B under stirring and continue to stir for emulsification to obtain emulsion b for later use, then mix potassium hydroxide with water to obtain a potassium hydroxide solution; then add the emulsion b obtained in step 3 under stirring Carry out saponification reaction in potassium hydroxide solution to obtain soap-based lubricants, and then carry out inspection and testing on each batch of products to check whether the specific gravity, pH value and other indicators of the products meet the quality requirements, and do a sample test for each...

Abstract

The invention discloses a preparation method of a lubricant. The preparation method comprises the following steps: heating base oil, adding stearic acid and an emulsifier with an HLB value of less than 6 when the oil temperature reaches 80-100 DEG C, uniformly mixing to obtain an oil phase for later use, uniformly mixing water and polyol to obtain a water phase A, and sufficiently stirring, slowlyadding the water phase A into the oil phase, continuously stirring and emulsifying to obtain an emulsion a for later use, and then uniformly mixing polyol, an emulsifier with an HLB value of more than 15 and water to obtain a water phase B; by adopting the preparation method, the grease can form an emulsion with a water-in-oil-in-water structure before saponification reaction, the emulsion is fully dispersed, the contact surface area of the grease and alkali liquor is increased in the saponification reaction, the reaction rate is increased, the base oil is heated before production, and then the raw materials are added, the process of heating the raw materials one by one can be omitted, energy can be saved, meanwhile, preparation steps are reduced, and the process is simplified.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to a preparation method of lubricants. Background technique [0002] Lubricants are substances used to lubricate, cool and seal the friction parts of machinery. They are divided into oily liquid lubricating oils, grease-like semi-solid greases and solid lubricants. Lubricants can cool, clean and prevent pollution to friction pairs. Most of them are distributed to the parts that need to be lubricated through the lubrication system, which has the advantages of good cooling performance, good permeability and little environmental pollution; [0003] Soap-based lubricants are widely used because of their good lubricating and protective effects on mechanical parts. However, in the prior art, the conventional oil saponification process requires high temperature and long-term reaction. Generally, the saponification temperature needs to be greater than 100°C. The time is at least 3 to 4 ...
