Abstract

The invention discloses a flame retardant acrylonitrile butadiene styrene (ABS) composition with high heat resistance and high toughness and a preparation method and the application of the composition; the flame retardant ABS composition comprises the components in parts by weight: 100 parts of high temperature resistant ABS masterbatches, 10-25 parts of environment-friendly brominated flame retardant, 5-10 parts of flame retardant synergist, 0.5-2 parts of maleic anhydride grafting styrene block copolymer (SEBS), 5-15 parts of flexibilizer and 0.5-5 parts of processing agent. The preparation method of the flame retardant ABS composition comprises two steps of: firstly, preparing the high temperature resistant ABS masterbatches; and secondly, mixing the temperature resistant ABS masterbatches, the environment-friendly brominated flame retardant, the flame retardant synergist, the maleic anhydride grafting SEBS, the flexibilizer and the processing agent, adding the mixture into a twin-screw extruder and then carrying out extruding and pelleting to obtain the flame retardant ABS plastic particles with high heat resistance and high toughness. The flame retardant ABS composition with high heat resistance and high toughness has high heat resistance, impact resistance and flame retardant effect as well as excellent stability and mechanical property, thus being widely applied to the fields such as a motor, a blower, a power supply box, a microwave oven, an electric cooker, an extension socket, an automobile instrument, a heat-resistant storage battery and the like.

Description

technical field [0001] The invention belongs to the technical field of functional polymer materials, and in particular relates to a flame-retardant ABS composition with high heat resistance and high toughness, a preparation method and application thereof. Background technique [0002] Styrene-butadiene-acrylonitrile (ABS) resin combines the rigidity and heat resistance of acrylonitrile, the gloss and processability of polystyrene, and the impact resistance of polybutadiene, and can be widely used in Household appliances, office equipment, instrumentation, transportation, building materials, daily appliances and packaging materials and other fields. However, the oxygen index of ABS resin is only 18, which is a flammable material. In order to improve its combustion behavior and make it difficult to burn or self-extinguish when it is away from fire, it is necessary to modify the flame retardant of ABS. However, for motors, hair dryers, power boxes, microwave ovens, rice cooke...
