Abstract

The invention provides a modified inorganic nanoparticle / epoxy resin composite material with higher friction and wear properties, comprising the following components by weight percentage: 95-99.9% of epoxy resin and 0.1-5.0% of modified inorganic nanoparticle, wherein the total quantity of the components is 100%. A preparation method of the material comprises the following steps of: firstly, respectively carrying out carboxylation modification and amino functionalization modification on an original carbon nano tube, mechanically mixing the obtained aminated carbon nano tube and epoxy resin, curing to obtain the carbon nano tube-enhanced epoxy resin composite material, and plating a layer of Ni-P-CNTs composite plating layer on the surface of the epoxy resin composite material by a surface chemistry composite plating technology. The effect of friction reduction and wear resistance can be achieved due to the organic synthesis between the filling of the nano-particles and the surface chemistry composite plating technology. Furthermore, the method is simple in technology and easy to implement, so that the abrasive resistance of the epoxy resin can be obviously improved.

Description

technical field [0001] The invention belongs to the technical field of composite materials and nanometer materials, and in particular relates to a modified inorganic nanoparticle / epoxy resin composite material with improved friction and wear performance and a preparation method thereof. Background technique [0002] As a commonly used thermosetting plastic, epoxy resin has excellent mechanical properties, low shrinkage, chemical corrosion resistance and thermal stability, so it has been widely used in petroleum pipelines, cars, machinery and other fields. With the continuous expansion of its application fields, people put forward higher and higher requirements for the wear resistance of epoxy resin. However, due to the three-dimensional cross-linked network structure of epoxy resin during curing, its friction and wear properties are poor. [0003] Carbon nanotubes have excellent mechanical properties, so they can be added to epoxy resin substrates as reinforcing materials t...
