Embodiment 1

[0050] The production method of the lubricating grease that the present embodiment enumerates comprises the following processing steps:

[0051] (1) Ingredients:

[0052] Heat up about 2 / 3 base oil (2500kg of ingredient oil), 480kg of lauryl hydroxystearic acid, 120kg of azelaic acid, 32kg of boric acid and 136kg of lithium hydroxide monohydrate aqueous solution (the mass ratio of water to alkali is 2:1) to 60-85°C, stir in the batching tank for 20-30 minutes to mix evenly, after the material is transferred to the feeding tank (at the same time, the second tank material is prepared in the batching tank to ensure continuous feeding production), start the pump cycle, and the feeding The material in the feed kettle is pumped into the tube furnace.

[0053] (2), saponification reaction:

[0054] The mixed material is subjected to saponification reaction and high-temperature compounding and refining in a tube furnace (heat convection coil, heat radiation coil). The time is 8-10 ...

Embodiment 2

[0063] raw material: Dodecyl hydroxystearic acid 400 kg, adipic acid 76 kg, boric acid 20 kg, lithium hydroxide monohydrate 112 kg, about 2 / 3 of the base oil (2300 kg of ingredient oil) saponification, about 1 / 3 of the base oil (blend oil 1500 kg) adjustment The consistency of grease product; Technology is with embodiment 1, and additive is with embodiment 1.

[0064] The saponification rate of the lubricating grease in this embodiment is 99.6%, and the performance testing indexes are shown in Table 4.

Embodiment 3

[0066] raw material: Lauryl hydroxystearic acid 400 kg, sebacic acid 112 kg, boric acid 28 kg, lithium hydroxide monohydrate 116 kg, about 2 / 3 of base oil (2500 kg of ingredient oil) saponification, about 1 / 3 of base oil (blend oil 1500 kg) adjustment The consistency of grease product; Technology is with embodiment 1, and additive is with embodiment 1.

[0067] The saponification rate of the lubricating grease of this embodiment is 99.4%, and the performance testing indexes are shown in Table 4.

Abstract

The invention discloses a production method of lubricating grease, in particular to a large-scale continuous production method of lubricating grease. The method is applicable to the production of grease of composite lithium base grease, lithium base grease, calcium base grease, composite calcium base grease and the like. The production method of the lubricating grease of the invention comprises five process steps: material preparation, saponification reaction, flash evaporation dewatering, thickening and post treatment. The saponification reaction carries out saponification reaction in a heatconvection coil pipe of a pipe type furnace, and the high-temperature compounding and refining is carried out in a heat radiation coil pipe. The furnace material feeding pressure is controlled between 1.0 and 1.5 MPa, the furnace outlet temperature is controlled between 250 and 280 DEG C, and the reaction time is between 8 and 10 min. The saponification rate of the production method of lubricating grease of the invention can reach 99.5 percent, the integral energy consumption can reach 1940 MJ / t, the energy source consumption is low, the production efficiency is high, and the quality is stable and reliable.

Description

technical field [0001] The invention relates to a production method of lubricating grease, in particular to a large-scale continuous production method of lubricating grease, which is suitable for producing complex lithium-based grease, lithium-based grease, calcium-based grease, and complex calcium-based grease and other oil production. Background technique [0002] Grease plays a role in reducing friction and wear, maintaining the normal operation of various mechanical equipment, prolonging the service life of mechanical equipment, etc., and occupies a very important position in industrial applications. The production process of lubricating grease has an important impact on the quality of lubricating grease. At the same time, the production method and production process are also of great significance in saving energy and reducing energy consumption. At present, the normal pressure method and contactor method are mostly used in the production of lubricating grease in our co...
