| titleOfInvention | High-strength flame-retardant rigid polyurethane foam prepared from boron-nitrogen-containing polycyclic polyether polyol and preparation method thereof |
| abstract | The invention discloses high-strength flame-retardant polyurethane rigid foam prepared from boron-nitrogen-containing polycyclic polyether polyol and a preparation method thereof. The invention introduces a flame-retardant polyether polyol containing boron-oxygen hexacyclic, aromatic ring and nitrogen heterocyclic ring in the preparation process of polyurethane rigid foam, which forms a component A with polyether polyol, polyester polyol, foam stabilizer, catalyst, cross-linking agent and foaming agent, wherein the component B is polymethylene polyphenyl polyisocyanate. A. And the component B is uniformly mixed and foamed under certain conditions, and the high-strength flame-retardant polyurethane rigid foam is obtained after curing and curing. The polyurethane rigid foam prepared by the invention has higher mechanical property and flame retardant property, and the density is 42.5-45.0kg/m 3 The compression strength is 0.45-0.58MPa, and the limiting oxygen index is 27.5-30.0%. |
