Abstract
The invention relates to an oil product light stabilizer, and belongs to the technical field of lubricating oil preparation. The oil product light stabilizer is characterized by being prepared from the following raw materials in parts by weight: 3-5 parts of an antioxidant 1010, 5-10 parts of an ultraviolet light absorber; 5-10 parts of an antioxidant 168; and balance of base oil. The preparation method comprises the following steps: mixing the antioxidant 1010 and the base oil according to a weight ratio of 1: 10-15 to obtain a component A; mixing the ultraviolet light absorber and base oil according to a weight ratio of 1: 10-20 to obtain a component B; mixing the antioxidant 168 and the base oil according to a weight ratio of 1: 10-15 to obtain a component C; and blending the component A, the component B and the component C by online blending and filling equipment and adding the blended components into lubricating oil to be renewed, wherein the adding mass of the oil product light stabilizer is 0.1%-0.2% of the lubricating oil to be updated. 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 oil light stabilizer. 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 process. In view of this, the applicant designed an oi...
