Abrasion-resistance and low-warpage polyformaldehyde material as well as preparation method and application thereof

The invention relates to an abrasion-resistance and low-warpage polyformaldehyde material as well as a preparation method and application thereof. The material mainly comprises the following components in part by weight: 100 parts of polyformaldehyde, 5 to 20 parts of alkali-free glass beads, 5 to 20 parts of PTFE powder treated by coupling agent, 0.1 to 2 parts of formaldehyde absorption agent, 0.1 to 2 parts of antioxidant and 0.1 to 2 parts of lubricant. Through properly adding the alkali-free glass beads and the PTFE powder treated by the coupling agent, the abrasion resistance and the size stability of the abrasion-resistance and low-warpage polyformaldehyde material are improved; through using the abrasion-resistance and low-warpage polyformaldehyde material, the abrasion resistance of a gear, a bearing and the like of a final product can be improved, and the shrinkage percentage of a modified polyformaldehyde product is reduced, so that the warpage is reduced, the stability of the final product is guar
