Abstract

Ultra high molecular weight polyethylene composite with low molar mass and high friction resistance, preparation and application thereof. Raw materials of 100 parts by weight of ultra high molecular weight polyethylene, 0.1-10 parts by weight of wear-resisting agent, 0.1-5.0 parts by weight of processing aid is prepared into highly friction resistant composite by mixing, chill-pressing, heating to melt, compression molding, cooling for shaping and cutting. The mentioned utra high molecular weight polyethylene has a matrix molecular weight of greater than 6 millionl. The mentioned wear-resisting agent is MoS2 surface treated by coupling agent, black lead, lubricating grease of molybdenum, copper powder, or mixture of more than two of them. The mentioned processing agent is organic silicon oil with high boiling point, polytetrafluroethylene, oxidized polyethylene wax, olefin or polyethylene wax with high boiling point, or mixture of more than two of them.

Description

technical field [0001] The invention relates to a polymer material and a preparation method thereof, in particular to an ultra-high molecular weight polyethylene composite material with low friction coefficient, high wear resistance and relatively high strength and a preparation method thereof. The invention also relates to the application of the above-mentioned materials, which are mainly used as wear-resistant materials for bridge structure supports and bearings. Background technique [0002] Polytetrafluoroethylene (PTFE) is widely used as a wear-resistant part in the manufacture of bridge supports and bearings because of its good self-lubricating and wear-resistant properties. However, with the continuous improvement of construction technology requirements, more and more requirements have been put forward for the compressive strength, compression creep performance, long-term wear resistance, allowable relative sliding speed and sliding distance bearing capacity of bridge...
