Problems solved by technology

The tribological study of pure polyetheretherketone resin shows that there are many obvious scratches and furrows on the worn surface of pure polyether ether ketone, and flake particles will fall off the surface of the material after a long time of work, mainly due to the friction process. The increase of medium friction temperature leads to thermoplastic deformation and flow of the surface material of polyetheretherketone under the action of periodic stress, which eventually leads to a large friction coefficient and high wear rate of pure polyetheretherketone

Abstract

The invention provides a polyether-ether-ketone/nanometer zinc oxide/carbon fiber wear-resistant composite material and a preparation method thereof, and application of the composite material to mechanical polishing of retaining rings, belonging to the technical field of polymer-based composite materials. The composite material is composed of, by mass, 75 to 90% of polyether-ether-ketone resin, 5 to 20% of carbon fibers coated by polyethersulfone and 2.5 to 7.5% of nanometer zinc oxide modified by a coupling agent, summing to 100%. To improve dispersibility of zinc oxide nanoparticles and reduce the agglomeration degree of the zinc oxide nanoparticles, the coupling agent is employed for surface modification of the zinc oxide nanoparticles; and polyethersulfone is used for physical coating of the surfaces of the carbon fibers so as to improve compatibility between the carbon fibers and polyether-ether-ketone. Compared with a polyether-ether-ketone composite material without any treatment, the wear-resistant composite material provided by the invention has more excellent strength, wear resistance and antifriction performance, is low in processing cost and is applicable to mechanical polishing of retaining rings.
