preparation example Construction

[0020] A preparation method of multifunctional composite grease, comprising the following steps:

[0021] S1 After mixing the fatty acid and oil, add a strong alkali aqueous solution to perform a saponification to obtain the first paste. When adding the lye, add it slowly. This process is carried out in a high-speed shearing machine in the reactor;

[0022] S2 Adding base oil to the paste, performing secondary saponification by cyclic shearing, to obtain a second paste, which is viscous, silky, uniform and free of particles; this process is carried out in a high-speed shearing machine in a reactor;

[0023] S3 Adding organic bentonite, anti-wear agent, anti-rust agent, stabilizer and extreme pressure agent to the second paste, and cyclically shearing to obtain the multifunctional compound grease. This process is carried out in a high-speed shearing machine in a reactor.

Abstract

The invention discloses multifunctional composite lubricating grease and a preparation method thereof. The multifunctional composite lubricating grease comprises the following components in parts by weight: 5-20 parts of fatty acid, 10-50 parts of grease, 12-30 parts of a strong alkali aqueous solution, 5-30 parts of organic bentonite, 2-5 parts of an anti-wear agent, 0.1-0.3 part of an anti-rust agent, 0.1-0.2 part of a stabilizer, 5-6 parts of an extreme pressure agent and 10-50 parts of base oil. The multifunctional composite lubricating grease has the following advantages that the dropping point reaches about 420 DEG C, the cutting resistance is high, the oxidation resistance is excellent, use is long-acting, the low-temperature fluidity is high, the use range is wide, the biodegradability is high, the extreme pressure performance is high, the rust resistance is strong, the water resistance is high, and the like.

Description

technical field [0001] The invention belongs to the technical field of lubricants, and in particular relates to a multifunctional composite lubricating grease. Background technique [0002] With the continuous updating of mechanical equipment, the requirements for lubricating grease are getting higher and higher. my country is a big consumer of lubricating grease in the world, but the quality of lubricating grease production is still relatively backward compared with developed countries. my country mainly produces anhydrous calcium-based grease and Ordinary lithium-based grease is the mainstay, and the sales of these two kinds of grease account for about 90% of the market. The dropping point of anhydrous calcium grease does not exceed 65°C, the dropping point of national standard lithium-based grease is 120°C, and the non-standard lithium-based grease is 80°C , the production process of these two kinds of grease is more polluting. To produce 4 tons of lubricating grease, 60 kg...
