Description
Polyurethane-modified TDE-85/MeTHPA epoxy resin was prepared with polyurethane prepolymer (PUP). The effects of the molecular weight of polypropylene glycol (PPG), the content of PUP, and other factors on the resin's mechanical properties were discussed. The results indicate that the tensile strength and impact strength of the material increase to maximum successively, then decrease with the increasing addition of PUP. The mechanical properties of materials obtained are distinctively different because of different molecular weight of PPG. When the PPG's molecular weight is 1000 and the mass fraction of PUP is 15%, the integrity mechanical property of the modified material is improved obviously. Its tensile strength is 69.39 MPa and its impact strength is 23.56 kJ/m2. (authors)
