Influence Factors Study on the Properties of Epoxy Resin Modified by Polyurethane

Abstract:

Polyurethane-modified epoxy resin was prepared with Polyurethane prepolymer(PUP). The effects of the PUP content and epoxy resin type on mechanical and thermal properties of materials were discussed. The results indicate that the tensile strength and impact strength of the material increase to maximum successively, and then decrease with the increasing addition of PUP. When the mass fraction of PUP was 15%, the tensile strength and the impact strength of materials were all the best. There were significant differences in mechanical and thermal properties of material for different epoxy, and the best results were cured epoxy TDE-85.
