Document Type and Number:
WIPO Patent Application WO/2024/066969
Kind Code:
A1
Abstract:
The present invention belongs to the field of polymers, and particularly relates to a polypropylene composition, and a preparation method therefor and use thereof. The polypropylene composition comprises the following components in parts by weight: 40-95 parts of a random copolymer polypropylene resin, 5-55 parts of a homopolymer polypropylene resin, 2-8 parts of a chlorinated polypropylene resin, 0.1-0.5 parts of an antioxidant, 0.24-0.4 parts of a light stabilizer, 0.1-0.5 parts of a nucleating agent, and 0.1-0.5 parts of a lubricant; the chlorinated polypropylene resin has a chlorine content of 20 wt%-26 wt%; the homopolymer polypropylene resin has isotacticity mmmm of > 97%. According to the present invention, by adding the chlorinated polypropylene resin, the nucleating agent, etc. to the random copolymer polypropylene resin and homopolymer polypropylene resin components for modification, the obtained polypropylene composition has relatively high visible light transmittance and ultraviolet light transmittance, and has excellent ultraviolet aging resistance, which can effectively prolong the service life of the prepared product.
