Abstract

The invention discloses a preparation method of a metal wearing self-repairing protective agent. The method includes: a) centrifugally separating a graphene oxide solution at low speed and collectinga supernatant for later use; physically mixing the supernatant with shell powder according to mass part ratio of 4-20:1, and freeze-drying the uniformly mixed solution to form loose composite powder of graphene oxide and shell powder; b) heating the composite powder under vacuum to constant dryness, and blending the composite powder, plant pine oil, a dispersion medium and a dispersant according to the weight part ratio of 20:2:80-100:10-15, and fully stirring the mixture; c) feeding the mixture into a shear machine, performing a reaction at 40-45 DEG C for 30-40 min, and when the reaction iscompleted, physically stirring the product to obtain the metal wearing self-repairing protective agent, which has excellent repairing effect and the like advantages.

Description

technical field [0001] The invention relates to the technical field of repairing materials for metal wear, and more specifically, to a preparation method of a self-repairing protective agent for metal wear. Background technique [0002] The wear and tear of moving parts caused by operation in mechanical equipment is an inevitable phenomenon. The damage of the moving parts caused the failure of the mechanical equipment. In order to reduce wear, lubricating oil is injected into the running parts, but the existing lubricating oil can only reduce wear, and the degree of reduced wear is limited. For this reason, some people have studied adding ore powder in lubricating oil to protect and repair the wear of metal running parts, but the protection and repair effect is relatively poor. The use of additives in lubricating oil can be used to enhance or supplement the efficacy of lubricating oil, but it cannot fundamentally solve the wear problem of parts, let alone repair the worn s...
