Abstract

The invention discloses a preparation method of a bio-based composite anti-wear agent, and belongs to the technical field of lubricating oil additives. When the self-made bio-based anti-wear substancephosphide is rubbed on the metal surface, the self-made bio-based anti-wear substance phosphide is firstly adsorbed on the metal surface; then C-O bond breakage occurs under the boundary condition, aphosphorous acid metal salt or phosphoric acid metal salt organic film is generated, the wear resistance of the product is improved, the self-made anti-wear substance is prepared with bio-oil as a base material, the degradability is excellent, the acid value is lower compared with that of an acid anti-wear agent, and metal is not prone to corrosion; self-made nanometer lanthanum oxide is also added; nanometer material of rare earth element, friction conditions, the rare earth element diffuses and permeates into the metal matrix to change the crack propagation resistance of the surface layer,an easy-to-shear film can be formed on the friction surface, the nano lanthanum oxide has higher diffusivity and self-diffusivity, a permeation layer or a diffusion layer with excellent wear resistance can be easily formed on the metal surface, and the wear resistance effect of the friction material is improved.

Description

technical field [0001] The invention discloses a preparation method of a bio-based composite antiwear agent, which belongs to the technical field of lubricating oil additives. Background technique [0002] Antiwear agent is a high-tech engine oil (lubricating oil) additive. The antiwear agents usually used in lubricating oil include sulfur antiwear agents, phosphorus antiwear agents, sulfur phosphorus antiwear agents, and halogen antiwear agents. Agents, organometallic antiwear agents and boron antiwear agents can reduce engine wear and increase engine power, so they are also called engine maintenance agents or powerful repair agents, which can prolong the service life of engine oil, save fuel and increase power. [0003] As one of the five major additives of modern lubricating oil, antiwear agent plays an important role in lubricating oil additives. However, with the rapid development of modern industry and the continuous improvement of human awareness of natural environme...
