Embodiment 1

[0026] Add 237g of Dagang lithium material and 46g of stearic acid mixture (including 4g of lauryl hydroxystearic acid) into the kettle, heat to 75°C, add 45g of isopropyl titanate, and keep warm for 90 minutes. After the heat preservation is over, continue heating to raise the temperature to 135° C., add 27 g of terephthalic acid, and keep the temperature at this temperature for 20 minutes. After the heat preservation is over, stop heating and add 50g of cold oil, add 5g of distilled water when the temperature in the kettle drops to 80°C, and resume heating, so that the temperature in the kettle rises to 175°C, and refine at this temperature for 45 minutes at high temperature. After high-temperature refining, stop heating, add 230g of remaining cold oil, and grind the product after the temperature of the material drops to 90°C to obtain the product, whose physical and chemical properties are shown in Table 1.

Embodiment 2

[0028] Add 340g of Dagang lithium material and 48g of stearic acid mixture (including 2g of lauryl hydroxystearic acid) into the kettle, heat to 90°C, add 40g of isopropyl titanate, and keep warm for 45 minutes. After the heat preservation is over, continue heating to raise the temperature to 140° C., add 29 g of terephthalic acid, and keep the temperature at this temperature for 40 minutes. After the heat preservation is over, stop heating and add 50g of cold oil, add 8g of distilled water when the temperature in the kettle drops to 90°C, and resume heating, so that the temperature in the kettle rises to 190°C, and refine at this temperature for 35 minutes. After high-temperature refining, stop heating, add 250g of remaining cold oil, and grind the product after the temperature of the material drops to 100°C to obtain the product, whose physical and chemical properties are shown in Table 1.

Embodiment 3

[0030] Add 330g of Dagang lithium material and 49g of stearic acid mixture (including 1g of dodecyl hydroxystearic acid) into the kettle, heat to 75°C, add 50g of isopropyl titanate, and keep warm for 60 minutes. After the heat preservation is over, continue heating to raise the temperature to 150° C., add 23 g of terephthalic acid and keep the temperature at this temperature for 60 minutes. After the heat preservation is over, stop heating and add 50g of cold oil, add 8g of distilled water when the temperature in the kettle drops to 90°C, and resume heating, so that the temperature in the kettle rises to 185°C, and refine at this temperature for 60 minutes at high temperature. After high-temperature refining, stop heating, add 280g of remaining cold oil, and grind the product after the temperature of the material drops to 90°C to obtain the product, whose physical and chemical properties are shown in Table 1.

Abstract

The present invention provides a preparation method for compound titanium base grease lubricant, according to the sequence, the following steps are included: firstly, fatty acid and base oil are mixed together and heated, when the temperature is raised to 70 to 90 DEG C, the tetraiopropyl titanate is added in for reaction; secondly, when the temperature is raised to 130 to 150 DEG C, aromatic acid is added in for reaction; thirdly, cool oil is added in for reducing the temperature, and distilled water is added in; fourthly, the temperature is increased to 170 to 200 DEG C for high temperature refining, the rest cool oil is added in, the temperature is reduced, and the reactant is ground to get the end product. The product got from the present invention has obviously better mechanical stability, as well as better abrasion resistance under the extreme pressure than that got from the prior technology.

Description

technical field [0001] The invention relates to a preparation method of lubricating grease, in particular to a preparation method of composite titanium-based lubricating grease, and a product obtained therefrom. Background technique [0002] As we all know, titanium not only has a high content in the earth's crust, but also has environmental friendliness, and is widely used in steel, oil refining, chemical industry and other fields. In the field of grease, in the early 1990s, Indian researchers successfully developed a high-performance and multifunctional composite titanium-based grease, which was recognized as a major breakthrough in the grease industry. From the performance point of view, the extreme pressure performance of the composite titanium-based grease (base grease) without adding any functional additives is comparable to or even exceeds that of the currently widely used extreme-pressure lithium-composite grease with anti-wear agents added; and the Grease has good ...
