Title:
POLYPROPYLENE COMPOSITION, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/179486
Kind Code:
A1
Abstract:
Disclosed in the present invention are a polypropylene composition, a preparation method therefor and an application thereof. The polypropylene composition comprises the following components in parts by weight: 38-83.7 parts of polypropylene resin, 0.5-2 parts of tannin, 0.1-2 parts of compound X, 15-25 parts of toughening agent, 0.3-1 part of antioxidant, and 0.2-1 part of weather-resistant agent, wherein the compound X has a group capable of generating a hydrogen bond with the tannin. By introducing a hydrogen bond ligand into the polypropylene resin, the performance influence of thermal aging on the material can be greatly relieved, the performance change caused by thermal aging is reduced, and the full-toughness requirement of low-temperature multi-axis impact after aging is realized.
