Title:
GLASS-FIBER-REINFORCED POLYPROPYLENE COMPOSITION, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/242298
Kind Code:
A1
Abstract:
Disclosed are a glass-fiber-reinforced polypropylene composition, a preparation method therefor and the use thereof. The polypropylene composition comprises the following components in parts by weight: 70-80 parts of a polypropylene resin, 5-10 parts of a polyethylene resin, 3-10 parts of a compatilizer, 10-20 parts of chopped glass fibers, 0.5-2 parts of a blow molding stabilizer, 0.1-0.8 parts of a light stabilizer, and 0-5 parts of a toughening agent, wherein the blow molding stabilizer comprises a hyperbranched epoxy resin and nano calcium carbonate. In the present invention, by using the polypropylene resin and the polyethylene resin combined with the blow molding stabilizer, the prepared glass-fiber-reinforced polypropylene composition can have a good three-dimensional blow molding performance and also have a high rigidity and heat resistance, and can thus be effectively used as an automobile pedal material.
