| titleOfInvention | Modified isocyanate prepolymer, polyurethane composite material, and preparation method and application thereof |
| abstract | The invention discloses a modified isocyanate prepolymer, a polyurethane composite material, a preparation method and application thereof, wherein the modified isocyanate prepolymer is a reaction product of isocyanate and a polymer (A) with a reactive group to the isocyanate, and the polymer (A) with the reactive group to the isocyanate contains low molecular weight polyamide resin polyol. The polyurethane composite material comprises a polyol mixture and a modified isocyanate prepolymer; the polyurethane composite material can be used for preparing high-performance polyamide-polyurethane hybrid materials. The invention has wide addition range of filling particles, good elasticity of hybrid materials, wide adjustable range of density and hardness and wide application. The addition of the low molecular weight polyamide resin polyalcohol improves the heat resistance of the hybrid material, so that the hybrid material can be applied to high temperature environment. |
