Attapulgite (ATP) nano-powder was functionalized by ionic liquid (IL) and silane coupling agent, and then functional ATP reinforced epoxy (EP) composite was prepared. The tribological properties of the composite rubbing against GCr15 bearing steels were investigated under dry friction conditions in a model TRM-1000 pin-on-disc tribometer. The tribological mechanism was analyzed based on the characterization of interfacial microstructures and tribo-chemical reactions. The results show that the surface functionalization of ATP significantly restrains the agglomeration and promotes its uniform dispersion in the resin. Moreover, the maximum wear resistance is achieved by filling EP with functionalized ATP modified by IL (3%, in mass fraction). The wear resistance is enhanced by 60%, compared to neat EP. Iron oxide and silicon oxide-based tribofilm formed at the friction interface mitigated the direct contact of the friction pairs, thus improving the wear resistance of EP materials. It is indicated that ATP could be used as a promising friction functional mineral filler in wear-resistant polymer.
