The invention provides a modified molybdenum disulfide wear-resistant agent and a preparation method, a wear-resistant agent composition, a nylon composition, a nylon material and applications. The modified molybdenum disulfide wear-resistant agent provided by the present invention comprises: an inner core and a shell layer, wherein the inner core is molybdenum disulfide nanoparticles; the material of the shell layer includes modified hyperbranched polymer, molybdenum disulfide nanoparticles and modified hyperbranched polymer The compounds are linked by an aminosilane coupling group. The modified hyperbranched polymer of the modified molybdenum disulfide anti-wear agent provided by the present invention contains a borate group and a polysiloxane group, and the borate group undergoes a chemical reaction on the friction surface to form diboron trioxide deposition Film, the siloxane groups migrate to the surface of the nylon resin to form a polysiloxane lubricating film, and when it is added to the nylon material, it is easier to disperse uniformly, reduce the occurrence of agglomeration, and when sliding friction occurs, the molybdenum disulfide layer Slip, boron trioxide deposition film and polysiloxane lubricating film synergistically reduce friction and improve wear resistance. |
