The invention discloses a polyester resin solid lubricating block and a preparation method thereof, belonging to the field of solid lubricating materials. The polyester resin solid lubricating block is prepared from the following components in parts by weight: 30-45 parts of unsaturated polyester resin, 25-35 parts of modified hollow glass beads, 8-20 parts of emulsified oil, 5-15 parts of lubricating filler, 3-7 parts of an accelerator, 4-10 parts of a curing agent, 2-5 parts of methyl silicone oil and 2-4 parts of a reactive diluent. The lubricating block prepared by the invention has good hardness and extremely low friction coefficient, can be widely applied to heavy-load sliding or rolling friction pairs, adopts the distilled residual oil obtained by preparing stearic acid by hydrolyzing palm oil, comprehensively utilizes resources, does not need to additionally add lubricating grease, has excellent self-lubricating performance, is beneficial to environmental protection and saving steel resources, is light and portable in high polymer material, and is beneficial to reducing the load of machinery. |
