Problems solved by technology

[0002] At present, domestic textile machinery is generally lubricated with greases such as general-purpose lithium-based grease, sodium-based grease, and white lithium-based grease. These greases are more or less difficult to be cleaned and removed after contacting textiles.
[0003] General-purpose lithium-based grease has excellent lubricating properties, but the oil stains left by general-purpose lithium-based grease on textiles cannot be removed by water washing, and the oil stains are darker in color; although sodium-based grease can be washed and removed, but due to the darker color of the grease , the appearance of textiles will still be affected after cleaning; although white lithium-based grease does not affect the appearance of textiles, it cannot be removed by washing

Embodiment 1

[0034] This embodiment relates to a special lubricating grease for textile machinery, which is prepared from the following raw materials in parts by weight:

[0035]

[0036] It is prepared by the following method:

[0037] 1) Warm up 40 parts of industrial white oil and stearic acid to 85°C, then add NaOH aqueous solution, then raise the temperature to 110°C for 2 hours;

[0038] 2) Then raise the temperature to 150°C and add 30 parts of industrial white oil; continue to heat up to 200°C for refining, keep the temperature for 10 minutes, and then cool down.

[0039] 3) Add benzotriazole below 110°C, add tert-butyl p-cresol below 105°C, grind at 105°C, add remaining industrial white oil and adjust the consistency.

[0040] 4) Degassing the prepared lubricating grease to obtain a finished product.

Abstract

The invention relates to the technical field of lubricating grease, in particular to lubricating grease for textile machinery, which is prepared from the following raw materials in parts by weight through chemical reaction: 10-15 parts of stearic acid, 1.5-2.2 parts of NaOH, 0.03-0.05 part of antirust agent, 0.3-0.5 part of antioxidant and 84-89 parts of industrial white oil. A light-color sodium soap thickening agent obtained by reacting stearic acid with NaOH is mixed with industrial white oil to prepare white basic lubricating grease easy to wash, and the white basic lubricating grease is subjected to mixing, grinding, degassing and other technological procedures to prepare the lubricating grease with good performance for textile machinery.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a special lubricating grease for textile machinery and a preparation method thereof. Background technique [0002] At present, domestic textile machinery is generally lubricated with general-purpose lithium-based grease, sodium-based grease, white lithium-based grease, etc. These greases are more or less difficult to be cleaned and removed after contacting textiles. [0003] General-purpose lithium-based grease has excellent lubricating properties, but the oil stains left by general-purpose lithium-based grease on textiles cannot be removed by water washing, and the oil stains are darker in color; although sodium-based grease can be washed and removed, but due to the darker color of the grease , After cleaning, it still has a certain influence on the appearance of textiles; although white lithium-based grease does not affect the appearance of textiles, it cannot be rem...
