摘要： A glass fiber reinforced polycarbonate composite material, a preparation method and an application thereof; the material includes the following components:
component A: 40 parts to 90 parts of a polycarbonate;
component B: 1.5 parts to 50 parts of a polysiloxane block copolymer;
component C: 5 parts to 60 parts of a glass fiber;
component D: 0.1 parts to 30 parts of a phosphorus-containing compound; and
component E: 0.01 parts to 30 parts of a polyolefin compound.
In the present invention, a polysiloxane block copolymer, a phosphonus-containing compound and a polyolefin compound with a specific content are selected to be added to formula of a glass fiber reinforced polycarbonate composite material so as to ensure that the finally 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 performances. 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 industry, communications industry, and construction industry.
