Abstract

The invention relates to a wear-resistant epoxy resin composite material, which is characterized in that the wear-resistant epoxy resin composite material is mainly prepared from an epoxy resin matrix material and a tungsten sulfide / graphene oxide nanocomposite material dispersed in the epoxy resin matrix material. The mass ratio of the tungsten sulfide / graphene oxide nanocomposite material to the epoxy resin matrix material is 0.0005-0.15:1. Wear resistance of the epoxy resin is enhanced by the adoption of the tungsten sulfide / graphene oxide nanocomposite material. Through excellent properties of the flaky tungsten sulfide / graphene oxide nanocomposite material and good dispersity of the nanocomposite material in the epoxy resin, the prepared composite material is endowed with excellent wear resistance.

Description

technical field [0001] The invention belongs to the field of preparation of polymer-based composite materials, and in particular relates to wear-resistant epoxy resin composite materials and a preparation method thereof. Background technique [0002] In recent years, epoxy resin has been more and more used in industrial fields to replace traditional metal materials due to its excellent mechanical properties, insulation properties, and process properties. However, epoxy resin has a relatively high friction coefficient and poor wear resistance, so it needs to be modified. [0003] According to reports, nano-materials are currently used to modify and improve the wear resistance of epoxy resins. Nano-silica, nano-silicon carbide, nano-alumina, carbon nanotubes and other materials are used to modify epoxy resin. However, nanomaterials are prone to agglomeration because of their large specific surface and high surface energy, which affects the improvement of the wear resistance ...
