Abstract

The invention relates to a production process of a regenerated base oil lubricating oil anti-light and heat stabilizer, belonging to the technical field of lubricating oil preparation. It is characterized in that it is made from the following raw materials, and the parts are all parts by weight: 2,6-di-tert-butyl-p-cresol, 3-5 parts; dialkyl zinc dithiophosphate, 3-5 parts; UV absorber, 5-10 parts; the rest is base oil; 2,6-di-tert-butyl-p-cresol and base oil are mixed according to the weight ratio of 1:10-15 to obtain component A; Zinc thiophosphate and base oil are mixed according to the weight ratio of 1:10-15 to obtain component B; the ultraviolet absorber and base oil are mixed according to the weight ratio of 1:10-20 to obtain component C; the above-mentioned component A , Component B and Component C are added to the lubricating oil to be renewed through online blending and filling equipment; the quantitative premixing device, nitrogen-adding pulse blending device and suction displacement device are sequentially set up from front to back.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil preparation, and in particular relates to an anti-light and heat stabilizer for regenerated base oil lubricating oil. Background technique [0002] In industrial production, the oxidation of lubricating oil base oils is mostly due to the oxidation, thermal oxidation and thermal degradation of various hydrocarbons, especially polycyclic aromatic hydrocarbons, in the air or under the action of engine combustion gases (especially under high temperature, light and metal catalysis). The process of oxidation and conversion into various oxidation products. [0003] The existing equipment is to add light stabilizer, and all crude oil or stock solution needs to be taken out after the production is stopped, and then replaced with new oil and refilled. The process of changing oil products is not only time-consuming and labor-intensive, but also shuts down the whole line, delaying the production proc...
