A nano-calcium carbonate/silane coupling agent (NCC/SCA) master batch was prepared by the reaction of a silane coupling agent (γ-aminopropyl triethoxy silane,trade name KH550) with the hydroxyl groups of the nano-CaCO3.Fourier transform infrared and thermal gravimetric analysis both indicated that the nanoparticles were grafted by the silane coupling agent.An epoxy resin was modified by adding the NCC/SCA master batch.A simple dipping test suggested that a better dispersion of the treated NCC in epoxy could be obtained than that of untreated NCC.Then, samples of epoxy nano-composites were prepared by a hot press process.The compressive property of the epoxy nano-composites was investigated.The results of the mechanical property tests revealed that the compressive strength, elastic modulus and the total fracture work of the epoxy matrix filled with the treated NCC were significantly improved relative to that filled with un-treated NCC.
