Document Type and Number:
WIPO Patent Application WO/2024/082522
Kind Code:
A1
Abstract:
The present invention relates to a flame-retardant polycarbonate composite material, a preparation method therefor and an application thereof. The flame-retardant polycarbonate composite material is characterized in comprising the following components in parts by weight: 10-99.9 parts polycarbonate resin, 5-50 parts styrene resin, 0.05-5 parts modified high-carbon resin, 1-30 parts toughening agent, and 0.01-2 parts stabilizer. Adding a specific modified high-carbon resin to the flame-retardant polycarbonate composite material results in a flame-retardant polycarbonate composite material which not only has a relatively low combustion rate, but also maintains excellent impact strength (including low-temperature impact strength) and good appearance.
