Abstract
The invention discloses a polycarbonate composition, which comprises the following composition in parts by weight: a, 86-99.9 parts of polycarbonate; b, 0.1-14 parts of flame retardant; wherein, a, b The sum of the parts by weight of the two components is 100 parts. In the present invention, when the content of perfluoro-substituted alkyl acid and its derivatives is ≤100ppm based on the total weight of the polycarbonate composition, the content of perfluoro-substituted alkyl acid and its derivatives in the formula of the polycarbonate composition is selected. Low water solubility, not easy to fail in the presence of water, can significantly improve the mechanical properties and flame retardancy of the polycarbonate composition under high temperature and high humidity conditions, its flame retardancy reaches 1.5mm / v-0, at 85% humidity And under the condition of 85 ℃, the retention rate of mechanical properties and flame retardant properties is high, and it is especially suitable for forming chargers and battery industries.
Description
technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a polycarbonate composition and its preparation method and application. Background technique [0002] Due to its excellent performance, polycarbonate flame retardant materials are widely used in the charger and battery industries, but the flame retardant and mechanical properties of polycarbonate flame retardant materials will be greatly reduced in humid environments, which cannot meet the high temperature and high temperature requirements of these industries. Industry requirements for wet conditions. [0003] A large number of documents describe how to improve the flame retardancy of aromatic polycarbonate resins, these methods include the addition of halogenated flame retardants or non-halogenated flame retardants. Halogenated flame retardants include brominated polystyrene, brominated polyphenylene ether, brominated bisphenol A epoxy resin, brominated styrene-mal...
