| titleOfInvention | A kind of heat-resistant polyester type method for preparing thermoplastic polyurethane elastomer |
| abstract | The invention discloses a kind of heat-resistant polyester type method for preparing thermoplastic polyurethane elastomer, the steps include: 1) PEPA, catalyst are added in reactor, under heating, vacuum condition, it is dehydrated to obtain component A；By 1,5 naphthalene diisocyanates, chain extender are mixed homogeneously with component A after heating respectively, then by double screw extruder extrusion reaction, obtain PAUR elastomer；2) by epoxy resin and step 1) PAUR that obtains elastomer blended blend, then blend is placed in temperature be 80～150 DEG C, under the conditions of pressure is 0.08～0.1MPa, it is dried 4～24h, obtains heat-resistant polyester type Polyurethane Thermoplastic Elastomer.Utilize the heat-resistant polyester type thermoplastic polyurethane elastic that this disclosure of the invention method prepares, the TPU application being mainly used under higher temperature. |
