| titleOfInvention | Polyurethane resin composite material, application thereof and high-strength high-modulus polyurethane material |
| abstract | The invention discloses a polyurethane resin composite material, application and a polyurethane material. The high-strength high-modulus polyurethane resin composite material comprises: the component A comprises oligomer polyol, a small molecular chain extender and a compatilizer; the component B comprises one or more of polymethylene polyphenyl isocyanate, diisocyanate and diisocyanate derivatives; and the component C is epoxy functionalized polyphenyl ether microsphere particles. A, B and the component C are stirred and mixed and then are subjected to heat curing to obtain the high-strength high-modulus polyurethane material, wherein the tensile strength can reach 62-82MPa, the bending strength can reach 110-135MPa, and the bending modulus can reach 2.8-3.0 GPa. |
