Title:
GLASS FIBER REINFORCED POLYCARBONATE COMPOSITE MATERIAL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/036613
Kind Code:
A1
Abstract:
Disclosed are a glass fiber reinforced polycarbonate composite material, a preparation method therefor and an application thereof, the material comprising the following composition: component A: 40-90 parts of polycarbonate; component B: 1.5-50 parts of a polysiloxane block copolymer; component C: 5-60 parts of glass fiber; component D: 0.1-30 parts of a phosphorus-containing compound; and component E: 0.01-30 parts of a polyolefin compound. In the present invention, specific contents of a polysiloxane block copolymer, a phosphorus-containing compound and a polyolefin compound are selected to be added to the formula of a glass fiber reinforced polycarbonate composite material so as to ensure that the final prepared composite material has a specific siloxane content and a specific weight ratio of phosphorus to silicon, so that the prepared composite material not only has the characteristics of excellent high modulus and high toughness, but also has excellent processing properties. Compared with conventional reinforcement modification means, the described composite material has both rigidity and toughness, and is especially suitable for fields such as automobiles, electronic and electrical products, the communications industry, and the construction industry.
