Document Type and Number:
WIPO Patent Application WO/2018/099217
Kind Code:
A1
Abstract:
Disclosed are a polycarbonate composition and a preparation method therefor. The polycarbonate composition comprises the following components in part by weight: 40-75 parts of polycarbonate, 0-35 parts of grafted copolymer, 5-30 parts of flame retardant, and 8-45 parts of mineral filler, wherein based on the total weight of the polycarbonate composition, the weight content of zinc element is 0.1-20 ppm. According to the present invention, the content of zinc element in the polycarbonate composition can be controlled in the range of 0.1-20 ppm by adding a zinc-containing compound having lower soluble zinc content in the polycarbonate composition and reducing or avoiding addition of other zinc-containing compounds, so that the prepared polycarbonate composition ages for 500 h at 80°C, the thermo-oxidative ageing MI increase rate is less than 30%, and the thermo-oxidative stability is significantly improved.
