Example Embodiment

[0030] Example 1:

[0031] 1) Component: overbased calcium sulfonate detergent (base value 320mgKOH / g): 200g (20.0%)

[0032]

[0033] 2) Production process: Put 200g (20.0%) of an overbased calcium sulfonate detergent with a base value of 320mgKOH / g into a small autoclave, add 10g (1%) of methanol to make calcium carbonate with a calcite structure, and stir quickly. Heat to 90~100℃, keep the temperature until the system materials gradually thicken, and gradually add 10g (1%) lithium hydroxide powder, 50g (5%) salicylic acid and twelve carbon to the system at 95~100℃. Dibasic acid 50g (5%), after a constant temperature reaction for 60 minutes, gradually increase the temperature, keep at 130~135℃ for 60 minutes, gradually increase the temperature to 220-222℃ for 5-10 minutes, adjust the consistency with polyolefin No. 8. The addition amount is 680g (68%), and the final grease obtained is 990g (methanol is volatilized during production, not in the components), and the working penetr...

[0034] Example 2:

[0035] 1) Component: overbased calcium sulfonate detergent (base value 320mgKOH / g): 350g (35%)

[0036]

[0037] 2) Production process: Put 350g (35.0%) of an overbased calcium sulfonate detergent with a base value of 320mgKOH / g into a small autoclave, add 30g (3%) of methanol to make calcium carbonate with calcite structure, and stir quickly. Heat to 90~100℃, keep the temperature until the system materials gradually thicken, and gradually add 20g (2%) lithium hydroxide powder, 80g (8%) salicylic acid and twelve carbon to the system at 95~100℃. Dibasic acid 100g (10%), after a constant temperature reaction for 60 minutes, gradually increase the temperature, keep the temperature at 130~135℃ for 60 minutes, gradually and slowly increase the temperature to 220-222℃ constant temperature for 5-10 minutes, adjust the consistency with polyolefin No. 8. The added amount is 420g (42%), and the final grease obtained is 970g (methanol is volatilized during production, not...

Abstract

The invention relates to a composition of compound calcium sulfonate-based lubricating grease for improving high-temperature performance and a preparation method thereof. The composition is prepared from a high-alkalinity calcium sulfonate cleaner, methanol, lithium hydroxide, salicylic acid, C12-C16 salicylic acid and base oil. The lubricating grease provided by the invention has relatively good high-temperature resistance and meets the seepage loss of ASTM D4290 and ASTM D1263 (industrial standard is SH/T0326). Experiments show that the seepage loss ranges from 5 to 10 which is obviously better than that (15-35g) of marketed products. The improving method provided by the invention can be used for prolonging the retentivity of the lubricating grease in a friction pair so as to ensure the operating reliability of equipment. The high-temperature performance of the prepared sample is obviously better than that of the marketed products.

Description

technical field [0001] The invention belongs to the technical field of lubricating grease, in particular to a method for improving the high-temperature performance of complex calcium sulfonate-based lubricating grease. Background technique [0002] With the development of industrial technology, the requirements for lubricating grease are getting higher and higher, especially for some iron and steel industry equipment, bearings and gears generally have a short service life in harsh environments, but most of these parts are steel enterprise equipment Once the core components are damaged, it will have a great impact on the quality of the products produced. Therefore, how to play a greater role in these core components, prolong the service life, and ensure the overall performance of the running parts is the direction pursued by the machinery and equipment industry. [0003] Grease usually contains two types of organic thickener and inorganic thickener. Most thickener types are o...
