The invention belongs to the technical field of polyoxymethylene materials, and specifically relates to a polyoxymethylene material with improved anti-friction and wear resistance and a preparation method thereof. The raw materials of the modified polyoxymethylene include capsules, a compatibilizer and polyoxymethylene; the capsules consist of a capsule shell and a capsule core, the raw material of the capsule shell is polyamide thermoplastics, and the raw material of the capsule core is an anti-wear oil agent. The modified polyoxymethylene material is obtained by mixing polyoxymethylene, capsules and compatibilizer, adding the mixture into a twin-screw extruder, and performing extrusion granulation. This technical scheme can solve the technical problem that polyoxymethylene materials in the prior art have unsatisfactory friction and wear resistance during long-term use. Oil-containing capsules are added into polyoxymethylene, and the surface of the capsules is damaged by friction during use to realize slow release of the oil layer, which ensures that polyoxymethylene products maintain excellent friction and wear resistance during use, thereby achieving the purpose of reducing product powder falling during long-term use and having ideal application and popularization value.
