WIPO Patent Application WO/2024/066487
Kind Code:
A1
Abstract:
The present invention relates to a polypropylene composite material having good paint adhesion, a preparation therefor and a use thereof. The components comprise: co-polypropylene, POE, talcum powder, a nucleating agent and a processing aid. The polypropylene composite material of the present invention has excellent performance in high-pressure water flushing tests on the ability to bond with paint, and the coating does not fall off; moreover, the material has good balance of rigidity and toughness, and the notched impact strength is greater than 25 KJ/m2; thus, the polypropylene composite material is suitable for automotive exterior paint-sprayed parts such as bumpers and exterior trim plates.
