A presente invenção se refere a um método de preparação de um material polimérico resistente ao desgaste, que compreende as seguintes etapas: Etapa 1: preparação de pó de diboreto de hfno epoxidado; Etapa 2: preparação de pó de diboreto de hfno modificado: dissolução de 2,2'-diaminodiphenyl disulfide in an organic solvent, stirring uniformly, adding epoxidized hafnium diboride powder, performing ultrasonic treatment, heating and stirring for reaction, collecting solid particles by suction filtration after reaction, washing with alcohol three times and drying to obtain modified hafnium diboride powder; Step 3: preparing wear-resistant polymer material: blending nylon resin and modified hafnium diboride powder in a twin-screw extruder, heating to melting, extruding and pelletizing to obtain the wear-resistant polymer material. Compared with traditional nylon materials, the polymer material prepared by the present invention not only has greatly improved mechanical strength, but also better wear resistance, high temperature resistance and low-temperature toughness.
