Abstract

The invention discloses a flame-retardant PC / HIPS composite material and a preparation method thereof. The composite material is prepared by the following raw materials: polycarbonate, polystyrene, flame retardant, flame-retardant synergist, flexibilizer, compatilizer, antioxidant and other adjuvants; and the preparation method comprises the following steps of: a. forced air drying the polycarbonate and the polystyrene respectively at 100-130 DEG C and 70-90 DEG C for 4-8 hours; b. preparing high impact polystyrene grafting glycidyl methacrylate compatilizer; c. weighing the dried polycarbonate, the polystyrene, the flame retardant, the flame-retardant synergist, the flexibilizer, the compatilizer, the antioxidant and other adjuvants; d. putting the raw materials in the step c into a high-speed mixer for dry mixing for 3-5min;and e. putting the mixed raw materials into a twin-screw extruder for melt extruding and pelleting. The composite material has prominent toughness and excellent flame retardance; in addition, the preparation method is simple, the operation is convenient and the cost is low.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and relates to a flame-retardant PC / HIPS composite material and a preparation method thereof. Background technique

[0002] Polycarbonate (PC) is a polymer with a large number of benzene ring structures in its molecular chain. The molecular chain is relatively rigid, not easy to crystallize and has a high glass transition temperature. The molecular chain structure determines that it has outstanding impact resistance, good creep resistance and dimensional stability, heat resistance, low water absorption, non-toxic, excellent dielectric properties, high gloss, and self-extinguishing. One of the five general-purpose engineering plastics, it is widely used in automobiles, electrical and electronic, construction, office equipment, packaging, sports equipment, medical care and other fields. Its output and consumption are second only to nylon engineering plastics, ranking second. However, po...
