Document Type and Number:
WIPO Patent Application WO/2024/114482
Kind Code:
A1
Abstract:
The present invention relates to the technical field of high polymer materials. Disclosed are a polypropylene composition and a preparation method therefor. According to the polypropylene composition in the present invention, a cellulose nanofibril having a specific length-diameter ratio is selected to match a maleic anhydride grafted polypropylene modifier having a high grafting rate as components, so that the compatibility of the cellulose nanofibril and a polypropylene resin matrix is remarkably improved; in addition, the cellulose nanofibril has good dispersion in product components, so that the paint adhesion of the product is improved, the damage of the outside to the surface of the product can be effectively resisted, and the scratch resistance of the product is improved. Also disclosed in the present invention are a preparation method for the polypropylene composition and a use of the polypropylene composition in the preparation of automobile plastic parts.
