Abstract
In order to modify the rheological properties of epoxy resin adhesive in casting moulding technology and improve its bonding quality, the effects of thixotropic agents of hydrophilic nano-silica, organic bentonite and the composite agent of the two thixotropic ones on the rheological properties of epoxy resin (E-44) were studied by the evaluation parameters of viscosity and thixotropic index in this paper. The variation regulation of rheological properties of epoxy resin (E-44) with different thixotropic agents as the storage time was also investigated. The results show that the two thixotropic agents play a significant role in thickening the density and modifying the thixotropy of the epoxy resin (E-44). Especially, the thickening and thixotropic effects of the composite agent of 3phr hydrophilic nano-silica with 6phr organic bentonite are the most remarkable and the storage stability is also excellent.
