| titleOfInvention | A kind of polyether polyol containing ester group to improve the compressive performance of slow rebound sponge and preparation method thereof |
| abstract | The invention discloses a polyether polyol containing an ester group to improve the compression resistance of a slow-resilience sponge and a preparation method thereof, and relates to the technical field of slow-resilience sponges. An ester group-containing polyether polyol is composed of the following components: polyol, caprolactone, initiator, cross-linking agent, polymerization monomer, and catalyst. The preparation method includes the following steps: S1, using a small molecular polyol with more than 2 functionalities as an initiator, adding an initiator stannous isooctanoate, and then adding caprolactone and a crosslinking agent for reaction polymerization to obtain a polycaprolactone polyol alcohol; S2, adding a catalyst to grow by polymerizing monomers to generate polyether polyol. The advantages of the present invention lie in that: the polyol is modified by reaction, the polyether is grafted on the polyester, and the polyether polyol obtained after modification has the presence of ester groups in the polycaprolactone segment, and the cohesion is large. , the tensile effect is good, it has a small viscosity at room temperature, and the slow-rebound sponge has good compressive performance. |
