| Abstract: | This article has studied the properties of epoxy resin modified with the stearamine.The properties of modified resin containing various amount of stearamine and curing agent were measured by impact tests,thermal deformation under load tests,shore hardness tests,DMA and TG.It was observed that the shore hardness and thermal deformation temperature slowly decrease with the stearamine content and form a wave crest with the increasing curing agent.However,the impact strength gradually increases with increasing stearamine concentration,attains a maximum and then decreases.The best formulation was found out,acquiring the biggest impact strength and the better heat stability. |
