Abstract

The invention discloses a halogen-free flame-retardant polycarbonate composite material and a preparation method thereof. The halogen-free flame-retardant polycarbonate composite material is characterized by having high transparency, and the flame retardance can reach 1mm UL94V-0 level. The polycarbonate composite material comprises the following components in parts by weight: 92.5 to 99 parts of polycarbonate resin, 0.5 to 5 parts of an organosilicone flame retardant, 0.1 to 0.5 part of a sulfonate flame retardant and 0.4 to 2 parts of aids. The preparation method comprises the following steps: mixing the polycarbonate resin, the organosilicone flame retardant, the sulfonate flame retardant and the aids in a high mixing machine, extruding and pelleting by double screws, drying and performing injection molding to obtain the polycarbonate composite material. The halogen-free flame-retardant polycarbonate composite material can reach 1.0 mm UL94V-0 level, has high transparency, is halogen-free and environment-friendly, and has excellent mechanical property, thermal property and processing property.

Description

technical field [0001] The invention relates to the technical field of polycarbonate modified materials, in particular to a halogen-free flame-retardant polycarbonate material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is a kind of thermoplastic engineering plastic with excellent comprehensive properties. Because of its excellent weather resistance, high impact resistance, and excellent electrical insulation, it is widely used in the automotive industry, instrumentation, electronic appliances and other fields. Polycarbonate itself has certain flame retardancy, but it cannot meet the occasions that require high or very high flame retardancy. Commonly used halogen-free flame retardants (phosphate ester flame retardants, sulfonate flame retardants, silicon-based flame retardants) flame-retardant polycarbonate can only achieve 1.5mm V0 transparency and 1.0mmV2, and cannot achieve ultra-thin 1.0mm V0 is transparent. Adding anti-dripping a...
