Embodiment 1

[0014] Embodiment 1, preparation functional lubricating grease

[0015] In a normal-pressure reactor with a volume of 100L and heating, cooling and stirring, add 42kg of 100°C viscosity 16.1mm 2 / s base oil, 3.48kg 12-hydroxystearic acid, heated to 80°C, added 0.507kg lithium hydroxide, 2.51kg water, heated to react, heated to 202°C, and then 16.52kg100°C viscosity 16.1mm 2 / s Base oil is added to the kettle, the temperature of the material in the reactor is lowered to 180°C, stirred, circulated and cooled, and then lowered to 110°C, circulated, filtered, homogenized, and degassed to become a product. The test results are listed in Table 1 and Table 2.

Embodiment 2

[0016] Embodiment 2, preparation functional lubricating grease

[0017] In a normal-pressure reactor with a volume of 100L and heating, cooling and stirring, add 35kg of 100°C viscosity 9.6mm 2 / s base oil, 3.15kg 12-hydroxystearic acid, heated to 82°C, added 0.459kg lithium hydroxide, 2.3kg water, heated to react, heated to 202°C, and then 21.85kg100°C viscosity 9.6mm 2 / s Base oil is added to the kettle, the temperature of the material in the reactor is lowered to 180°C, stirred, circulated and cooled, and then lowered to 110°C, circulated, filtered, homogenized, and degassed to become a product. The test results are listed in Table 1 and Table 2.

Embodiment 3

[0018] Embodiment 3, preparation functional lubricating grease

[0019] In a normal-pressure reactor with a volume of 100L and heating, cooling and stirring, add 35kg of 100°C viscosity 12.3mm 2 / s base oil, 3.15kg12-hydroxystearic acid, heated to 82°C, added 0.459kg lithium hydroxide, 2.3kg water, heated to react, heated up to 202°C, and then 21.85kg100°C viscosity 44.5mm 2 / s base oil is added to the kettle, and the temperature of the material in the reactor is lowered to 180°C, stirred, circulated and cooled, and continued to drop to 110°C, circulated, filtered, homogenized, and degassed to become a product. The test results are listed in Table 1 and Table 2.

Abstract

The invention discloses a functional grease lubricant and a preparation method thereof. In the preparation method, fraction oil obtained through high-acid naphthene base crude oil is used as the base oil of the grease lubricant and is reacted with 12 hydroxy stearic acid, lithium hydroxide and water for obtaining the finished product of the functional grease lubricant. The viscidity of the fraction oil under the temperature of 100 DEG C is 9.5 to 44.5mm<2>s and is preferably to be 9.5 to 16.5mm<2>s and is more preferably to be 9.5 to 44.5mm<2>s; the acidity is equal to or more than 0.5mgKOH / g; the weight portion ratio of the base oil of the grease lubricant to the 12 hydroxy stearic acid, lithium hydroxide and water is 49 to 65: 3.0 to 3.6: 0.45 to 0.53 : 2.2 to 2.6. The preparation method provided by the invention can reduce the consumption of a thickening agent, improve the structure of the grease lubricant and reduce the production cost. The produced grease lubricant meets the index requirements of the National Standard GB7324-94.

Description

technical field [0001] The invention relates to the fields of petroleum refining and chemical industry, in particular to a functional lubricating grease and a preparation method thereof. Background technique [0002] At present, in the production of lubricating oil base oil, there is a production pattern of lubricating oil base oil in which the "three sets of furfural clay" processing technology and hydrotreating technology coexist. No matter the production of lubricating oil base oil by "hydrotreating" or "old three sets of furfural clay" process, naphthenic acid and most of polycyclic aromatic hydrocarbons and colloids in raw materials are removed. Due to the removal of naphthenic acid, the acid value of the grease base oil is less than or equal to 0.05mgKOH / g. Usually, in the production process of lithium-based grease, naphthenic acid needs to be added to improve the colloidal structure and performance of the grease. [0003] The general production process of lubricating...
