Abstract

The invention relates to a composition for preparing a self-lubricating wear-resistant material, a self-lubricating wear-resistant paint, a self-lubricating wear-resistant coating, and a self-lubricating wear-resistant material, and belongs to the technical field of self-lubricating materials. The composition for preparing the self-lubricating wear-resistant material is mainly composed of a resinand the following components in parts by weight: 11-12 parts of molybdenum disulfide, and 0.088-0.3 part of graphene. The composition uses molybdenum disulfide as a lubricant and graphene as a lubricating additive, the similarity of the two-dimensional layered structure of molybdenum disulfide and graphene is utilized, molybdenum disulfide and graphene are compounded according to a specific ratioto prepare the wear-resistant material, the synergistic lubricating effects of molybdenum disulfide and grapheme can be exerted, and thus the wear resistance and self-lubricating property of the wear-resistant material are significantly improved. Particularly the self-lubricating anti-friction wear-resistant coating prepared by using the composition has good lubrication and anti-friction property,wear resistance and environmental adaptability under dry friction and seawater conditions.
