The invention discloses an enhanced self-lubricating joint bearing gasket material preparation method, which comprises: coating inorganic nano-powder with a borate polymer, and under the synergistic effect of organic-metal coordination and B-N coordination, simply and efficiently preparing a core-shell structure nano-powder with an adjustable shell thickness. According to the present invention, byusing the strong affinity between the borate polymer and the matrix resin and the hydrogen-bond interaction between the surplus boric acid or catechol functional group on the surface and the matrix resin, the dispersity of the nanoparticles in the matrix resin is improved, and the comprehensive mechanical properties of the coating material are improved. 本发明公开了一种增强型自润滑关节轴承衬垫材料的制备方法，采用硼酸酯聚合物包覆无机纳米粉体，在有机-金属配位和B-N配位协同作用下简单高效制备壳层厚度可调的核壳结构纳米粉体，利用硼酸酯聚合物和基体树脂较强的亲和力和表面富余的硼酸或邻苯二酚官能团与基体树脂之间的氢键作用，提升纳米粒子在基体树脂中的分散性，提高涂层材料的综合力学性能。
