Abstract

The invention discloses a preparation process of a lubricating oil thickening agent. Firstly, raw materials are prepared in parts by weight, the raw materials comprise base oil, viscosity index agent dry glue and an antioxidant, and the base oil is divided into dissolved oil, diluting oil and cleaning oil according to functions; injecting the dissolved oil into a sol kettle to be heated to 120-150 DEG C, and performing heat preservation; sequentially adding the viscosity index agent dry glue and the antioxidant into the dissolving oil, and stirring and mixing to obtain a mixed solution; stopping heat preservation, injecting diluent oil into the sol kettle for mixing and stirring, completing dilution and cooling, and then conveying the diluent oil into a buffer tank for buffering; injecting cleaning oil into the sol kettle for cleaning and then conveying into the buffer tank; treating the oil product in the buffer tank through a homogeneous emulsification pump to obtain the lubricating oil thickening agent; according to the invention, the viscosity index agent dry glue is prevented from thermal oxidation deterioration by selecting the viscosity index agent dry glue, adding the antioxidant, controlling the temperature of the dissolving oil, the particle size of the viscosity index agent dry glue, stirring time, diluting and cooling, and the like, so that the performance of the lubricating oil thickening agent is improved.

Description

technical field [0001] The invention relates to the technical field of lubricating oil production, in particular to a preparation process of a lubricating oil thickener. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. As long as it is applied between two relatively moving objects and can reduce the friction and wear of the two objects due to the function of contact, it is a lubricating oil. [0003] Viscosity index improver is a high-molecular-weight oil-soluble compound polymerized from low-molecular-weight monomers. The monomers can be the same or different molecules. They are generally rubbery or solid at room temperature, so they are generally The viscosity index improver is called viscosity index dry glue...
