Embodiment Construction

[0017] After the components are fully mixed under high-speed stirring, they are melted, kneaded, extruded, cooled, dried, pelletized and packaged through a twin-screw extruder. The temperature of each partition of the screw barrel should be kept between 180 and 240 °C. The length-to-diameter ratio of the twin-screw extruder is 32-40, and the screw speed is 300-500 rpm.

[0018] In this experiment, acrylonitrile-butadiene-styrene polymer (ABS) and HIPS with a butadiene rubber content of 3-10%, brominated triazine and decabromodiphenylethane flame retardants were used.

Abstract

The present invention discloses a flame-retarding polystyrene resin composite containing brominated triazine and a preparation method thereof. The composite comprises the components with the following portions: 75 to 91 percent of polystyrene resin, 6 to 18 percent of brominated triazine flame retarding agent, 2 to 7 percent of retardant synergist and 0.1 to 1 percent of antioxidant, which are one-time extruded and processed by a double screw extruder. The composite of the invention has good mechanical performance, unchanged processing performance, high flame retarding efficiency, high-grade flame retarding performance, small environmental pollution and small human harm, can meet the strict requirements for environment protection internationally at present, simultaneously has the advantages of easy forming and good surface glossiness, and is suitable for making shells of various electrical appliances.

Description

technical field [0001] The invention relates to the technical field of high-impact polystyrene resin modification, in particular to a flame-retardant polystyrene resin compound containing bromotriazine and a preparation method thereof. Background technique [0002] Polystyrene resins mainly include the following resins: high impact polystyrene, acrylonitrile-butadiene-styrene polymer, acrylonitrile-styrene-chlorinated polyethylene graft copolymer, acrylate-styrene - Acrylonitrile graft copolymers, EPDM-styrene-acrylonitrile graft copolymers and methyl methacrylate-butadiene-styrene polymers. Among them, high-impact polystyrene and acrylonitrile-butadiene-styrene polymer are the most used in the market. [0003] Polystyrene (PS) was industrialized in 1930 by I.G Farben (predecessor of BASF) in Germany. As one of the five general-purpose plastics, it has the advantages of excellent formability, hard quality, transparency, rigidity, electrical insulation, low hygroscopicity, ...
