Abstract
The invention relates to a regenerated base oil lubricating oil anti-photothermal stabilizer, and belongs to the technical field of lubricating oil preparation. The stabilizer is characterized by being prepared from the following raw materials in parts by weight: 3-5 parts of 2, 6-butylated hydroxytoluene, 3-5 parts of zinc dialkyl dithiophosphate, 5-10 parts of an ultraviolet light absorber, withthe balance of base oil. the preparation method comprises the following steps: mixing 2, 6-butylated hydroxytoluene and base oil according to a weight ratio of 1: 10-15 to obtain a component A; mixing zinc dialkyl dithiophosphate and the base oil according to the weight ratio of 1: 10-15 to obtain a component B; mixing the ultraviolet light absorber and the base oil according to a weight ratio of1: 10-20 to obtain a component C; and adding the component A, the component B and the component C into lubricating oil to be updated through online blending and filling equipment. A quantitative premixing device, a nitrogen adding pulse blending device and a suction type replacement device are sequentially connected 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...
