Fabric liner coating material of self-lubricating joint bearing and preparation method thereof

The invention provides a fabric liner coating material of a self-lubricating joint bearing and a preparation method thereof, and relates to a self-lubricating coating material and the preparation method thereof. The coating comprises the following components: 60 to 80 parts of epoxy resin, 0.1 to 5 parts of POSS (Polyhedral Oligomeric Silsesquioxane), 5 to 25 parts of polytetrafluoroethylene powder, 15 to 35 parts of a diluent, 0.5 to 5 parts of a silane coupling agent, 10 to 25 parts of a curing agent and 0.1 to 1 part of a surface active agent. The environment-friendly method and a way for preparing the self-lubricating abrasion-resistant liner coating material is provided; and the nanoscale polytetrafluoroethylene powder which is the same as the material of a fabric body is served as a filler in the formula, so that the friction coefficient is decreased greatly and the product appearance is improved. In addition, the nanoscale, the high surface energy and the similar 'bearing ball' effect of a cage shaped structure of the POSS are utilized, so that the friction reducing performance, the abrasion resisting performance and the self-lubricating performance of the coating are improved effectively.
