Document Type and Number:
WIPO Patent Application WO/2021/042692
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for preparing PEBAX into a TPV foam material, and a TPV foam material, said method comprising the following steps: ① pre-vulcanization of PEBAX/MPU or PEBAX/EPDM-MAH: mixing a vulcanizing agent and an alkaline filler evenly to prepare a mixture, and plasticizing MPU or EPDM-MAH into softened MPU or EPDM-MAH; kneading the mixture and the plasticized MPU or EPDM-MAH until the components are evenly mixed to obtain a kneaded material; blending the kneaded material and PEBAX to obtain a TPV material, and performing a vulcanization operation on the TPV material to obtain a pre-vulcanized TPV material; ② supercritical foaming: after cooling to room temperature, placing the pre-vulcanized TPV material in a high-pressure reaction vessel and performing supercritical foaming to obtain a TPV foam material. The TPV foam material obtained in the present invention combines excellent performance of two types of material, is lightweight and flexible, and has good resilience. Tensile strength, tearing strength, peel strength and adhesiveness are all greatly improved relative to PEBAX, and the material has good formability, excellent energy absorption and shock absorbing performance, and is more suited for fields such as the manufacturing of shock absorbing components or shock absorbing packaging material.
