Abstract


In this work we have synthesized a new bifunctional epoxy resin namely diglycidyl 3-aminopropyl triethylsilane (DGAPTES).
This resin was synthesized in two steps: the first one is condensing the epichlorohydrin with 3-aminopropyl triethylsilane; the second is introducing the calcium carbonate as a base to form the oxirane cycle.
The resin obtained was characterized by infrared Fourier transformation spectroscopy (FTIR), its chemical structure was also confirmed by the nuclear magnetic resonance of 1H and proton and carbon 13C (1H NMR and 13C NMR) on the one hand, and we have improved the thermal properties of the standard resin (DGEBA) by adding an amount of (DGAPTES) as an organic load in the standard matrix, on the other hand. This formulation has been studied by thermogravimetry as a macroscopic approach. The uptake of humidity of the standard DGAPTES and the crosslinked DGEBA/DGAPTES/MDA according to 80%/20%/traces was studied in order to improve the Fickien behavior.


Author Keywords: DGEBA, DGAPTES, formulation, thermogravimetry and humidity uptake.
