Title:
FOAMED THERMOPLASTIC POLYSILOXANE-POLYURETHANE BLOCK COPOLYMER, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/228541
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of chemical material synthesis, and especially relates to a foamed thermoplastic polysiloxane-polyurethane block copolymer, a preparation method therefor and a use thereof. The foamed thermoplastic polysiloxane-polyurethane block copolymer comprises a thermoplastic polysiloxane-polyurethane block copolymer having a silica content of 0.5-30 wt% and a Shore hardness of 30A-80D. The thermoplastic polysiloxane-polyurethane block copolymer is used int he present invention to prepare the foamed thermoplastic polysiloxane-polyurethane block copolymer. On the basis that the thermoplastic polysiloxane-polyurethane block copolymer has excellent properties of being skin-friendly, yellowing-resistant, stain-resistant and penetration-resistant and excellent mechanical properties, the obtained foamed thermoplastic polysiloxane-polyurethane block copolymer is also light in weight and has a high resilience on the basis of these excellent properties.
