| titleOfInvention | Polyurethane elastomer and preparation method thereof |
| abstract | The invention belongs to the field of polymers, and particularly relates to a polyurethane elastomer and a preparation method thereof. The preparation method of the polyurethane elastomer comprises the following steps: (1) mixing diisocyanate and a silane coupling agent and carrying out condensation reaction, wherein the silane coupling agent has two amino groups, and the molar ratio of the diisocyanate to the silane coupling agent is (5-10): 1, so as to obtain a condensation reaction product; (2) and carrying out polycondensation reaction on the condensation reaction product, polyol and a chain extender to obtain a product containing the polyurethane elastomer. The polyurethane elastomer prepared by the method provided by the invention has high bonding performance. |
