PREPARATION AND CHARACTERIZATION OF BIOMASS-BASED EPOXY ADHESIVES WITH SILANE-TREATED SILICAS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 1
Abstract
In this work, we prepared biomass-based epoxy adhesives with silane-treated silicas. The effect of three types of silane-treated silicas on adhesive characterization of epoxidized soybean oil (ESO)/epoxy adhesives with different contents of ESO, i.e, 0.5, 1.0, and 2.0 wt.% was studied. As a result, the lap shear strength of the adhesives was increased as a polar component of surface free energy and oxygen functional groups of the silicas. The lap shear strength of the adhesives was also increased with increasing ESO content upto 2.0 wt.%. Consequently, ESO was one of the candidate materials for improvement of adhesives in bio-based epoxy adhesive system.
