Description

technical field [0001] The invention belongs to the technical field of corrosion protection of wear-resistant coatings, and in particular relates to a p-phenol-based polyetheretherketone resin in a wear-resistant composite coating in a marine corrosion environment and a preparation method thereof. Background technique [0002] Polymer-based friction materials generally contain three elements, namely matrix, anti-friction component and anti-wear component. The earliest polymer-based friction material in the world is a phenolic resin-based composite material. With the rapid development of the polymer industry, new synthetic resins continue to emerge. Polyethylene, polytetrafluoroethylene, nylon, epoxy resin, polyetherimide and polyetheretherketone have been developed successively, making polymer-based friction materials widely used in many fields. [0003] Polyetheretherketone resin has the advantages of high heat resistance, radiation resistance, chemical resistance, fatigue...
