Problems solved by technology

For the motor industry, the minimum operating temperature of traditional lubricating oil is -30°C. If the temperature is lower, the lubricating oil will solidify and cannot rotate, which severely limits the application of the motor industry in severe cold and harsh environments.

Abstract

The invention discloses low-temperature-resistant lubricating oil and a preparation method thereof. The lubricating oil is prepared from components in parts by weight as follows: base oil, nano tin powder, 1-phenyl cyclopentanecarboxylic acid, nano vanadium hydroxide, silicotungstic acid, calcium chloride, bis(cyclopentadiene)hafnium dichloride, sulfated castor oil, calcium gluconate, sodium dodecyl benzene sulfonate, a dandelion extracting solution, barium dinonyl naphthalene sulfonate, glycolic acid, ethoxy modified trisiloxane, lauryl alcohol phosphate acid ester, an antioxidant 1035 and glycerin, wherein the base oil is prepared from poly-alpha-olefin, castor oil and polyethylene glycol in the weight ratio being 5:2:4. The prepared lubricating oil has the lower pour point, smaller wear spots and the maximum non-seizure load, shows good low-temperature resistance, wear resistance and lubricating effect, is applicable to low-temperature complex environments and can effectively prolong the service life of use equipment.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a low-temperature resistant lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil plays an important lubricating role in mechanical transmission and is mainly used in mechanical equipment, automobiles, home appliances and other fields. Lubricating oil is generally composed of base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil and give new performance to lubricating oil. [0003] In addition to good anti-wear, anti-rust performance, load resistance performance, oxidation resistance, etc., lubricating oils have different performance requirements for different types of transmission machinery and application fields. For the motor industry, the minimum operating temperature of tra...
