Problems solved by technology

Existing lubricating base oils will produce yellowing phenomenon when exposed to ultraviolet rays, especially its light components have poorer UV resistance. The main reason for discoloration is oxidation, due to the combination of unsaturated free radicals in lubricating base oils , triggering the oxidation of all oil products and overall discoloration
At the same time, the molecular structure of the light component of the existing lubricating base oil will be destroyed by the high temperature of traditional distillation during processing, and it will also bring a little odor

Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention are clearly described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] The invention discloses a method for processing anti-yellowing lubricating base oil, which specifically includes the following steps:

[0021] Extract light components, select hydro-refined 60N lubricating base oil, flash distillation for a very short time under a residual pressure of 20Pa, supercritical point high vacuum environment, the distillation temperature is controlled at 165-170℃, and the distillation time is controlled at Within 30s;

[0022] The light components are recovered. The light components of the lubricating base oil vol...

Abstract

The invention discloses anti-yellowing lubricating base oil and a processing method thereof. The processing method comprises the following steps: lightweight component extraction, lightweight component recovery, steam purification, circulating water cooling, ultraviolet irradiation and finished product storage. The anti-yellowing lubricating base oil prepared according to the technical scheme is low in viscosity, colorless, and free from extraneous odor; no yellowing phenomenon is generated after long-time irradiation of ultraviolet rays, so that the purity is high and the performance is reliable; a supercritical point flash technology is utilized, so that lubricating base oil can be distilled under the condition of ultimate vacuum, and a molecular structure of the lightweight component can be protected to an extremely great degree.

Description

Technical field [0001] The invention relates to the technical field of lubricating base oils, in particular to a lubricating base oil and a processing method thereof. Background technique [0002] Lubricating base oil is an indispensable chemical product in the production and life of modern society. It is widely used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Existing lubricating base oils will produce yellowing when exposed to ultraviolet rays, especially their light components are less resistant to ultraviolet rays. The main cause of discoloration is oxidation, because the unsaturated free radicals in the lubricating base oils combine with oxygen , Causing oxidation of all oils and overall discoloration. At the same time, the molecular structure of the light component of the existing lubricating base oil will be destroyed by the high temperature of traditional distillation during processing, and will a...
