WIPO Patent Application WO/2024/066525

A1

A reinforced polypropylene composite material, a preparation method therefor, and use thereof. The enhanced polypropylene composite material comprises the following components: 30-78 parts by weight of unimodal polypropylene homopolymer, 5-30 parts by weight of unimodal polypropylene random copolymer, 5-20 parts by weight of bimodal polypropylene, 10-30 parts by weight of a flat glass fiber powder, 2-10 parts by weight of a compatibilizer, 0.1-1 part by weight of an antioxidant, 0.05-0.5 parts by weight of a nucleating agent, and 0.1-0.5 parts by weight of a synergist. The length of the flat glass fiber powder is 30-50 μm. The synergist comprises epoxy resin, triisopropanolamine, hydrotalcite, and zinc stearate. The matrix resin of the present technical solution is compounded of three polypropylene materials and used in conjunction with flat glass fiber powder and the specific synergist to provide a reinforced polypropylene composite material having excellent airtightness, high-temperature static-pressure durability, and resistance to alternating high and low temperatures.
