Abstract

The invention discloses a PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene) composite material as well as a preparation method and application thereof, and belongs to the technical field of high polymer materials. The preparation method of the PC / ABS composite material comprises the following steps: uniformly mixing the ABS resin, the toner, the auxiliary agent and the PC resin to obtain a mixture A; uniformly mixing the compound pearl powder and the PC resin to obtain a mixture B; adding the mixture A into an extruder; adding the flame retardant into the extruder and mixing with the mixture A; the mixture B is added into the extruder to be mixed with the mixture A and the flame retardant, the melting temperature ranges from 220 DEG C to 250 DEG C, and the PC / ABS composite material is obtained; wherein the mixture B is added into the extruder at 7 / 12-3 / 4 of the total melt blending reaction process. The PC / ABS composite material disclosed by the invention has pearlescent and fantastic color effects while ensuring the flame retardant property, and can present different colorful effects at different angles.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and more particularly, to a PC / ABS composite material and a preparation method and application thereof. Background technique [0002] Polycarbonate (PC) is a thermoplastic engineering plastic with excellent comprehensive properties. It has excellent mechanical properties and certain flame retardancy. Its own flame retardancy can reach V2 level. However, polycarbonate (PC) material also has its shortcomings, such as poor processability, etc., and is usually blended with styrene-butadiene-acrylonitrile (ABS) to form an alloy. [0003] With the continuous introduction of global safety regulations, in terms of household appliances such as fireproof enclosures, switches, and connectors, the plastic materials used are required to have good flame retardancy, and the flame retardancy must reach V0 level. In order to improve the flame retardant performance, in the prior art, a large amount of f...
