| titleOfInvention | Preparation process of polyurethane runway composite material |
| abstract | The invention discloses a preparation process of a polyurethane runway composite material, which comprises the following steps: 1) under the inert atmosphere, enabling polyol and diisocyanate to react under the action of a chain extender containing a disulfide bond and a catalyst to generate a polyurethane prepolymer; 2) and uniformly mixing the polyurethane prepolymer, the compound drier, the tri (2-carboxyethyl) phosphine and the EPDM rubber particles to prepare the polyurethane runway composite material. According to the method, the TCEP is utilized to break the disulfide bond in the chain extender, so that sulfydryl is generated and reacts with NCO groups quickly, the drying speed of the aliphatic isocyanate adhesive system is increased, and meanwhile, the runway has excellent yellowing resistance. |
