This research aimed to produce foams with properties of good adhesion. Blend-modified epoxy/polyurethane foam was synthesized by step-preparation method. The effect of epoxy mass fraction on the foam adhesion and the changing pattern of adhesion property were studied. The performance of adhesion, internal structure and thermal stability of the foam were characterized. The results showed that the mass fraction of epoxy had great effect on the adhesion property of the foam. The optimal adhesive property and the thermal stability were obtained when the mass fraction of epoxy was 50%, and the epoxy/polyurethane foam developed a structure of interpenetrating polymer networks.
