Synthesis and research of epoxy resin toughening agent
In this paper, a synthesis method of epoxy resin toughening agent was presented, then the chemical composition and molecular number were studied, which include the DSC curves analysis, the fracture surface morphology and bonding strength. In addition, the mechanism of epoxy resin toughening agent and the effect of toughening agent's content to bonding strength were studied. The testing results reveal that this toughening agent can form a micro two phase structure in epoxy amine system, which results in the stable chemical properties and excellent physical properties.
