Embodiment 1
[0027] High-impact polystyrene 84.0 parts, brominated flame retardant decabromodiphenylethane 8.0 parts, brominated flame retardant tetrabromobisphenol A 3.0 parts, auxiliary flame retardant antimony trioxide 4.0 parts, stabilizer 0.2 part of tris(2,4-di-tert-butylphenyl) phosphite, 0.6 part of lubricant magnesium stearate.
[0028] The preparation method is as follows:
[0029] (1) Measure each component according to the formula;
[0030] (2) Pour high-impact polystyrene and diffusion oil into the high-speed mixer first, and mix for 3 minutes;
[0031] (3) Then pour the brominated flame retardant, auxiliary flame retardant, stabilizer, lubricant, and diffusion oil into the high-speed mixer in sequence, and mix for 3 minutes;
[0032] (4) The fully mixed materials are melted, mixed, extruded, cooled, pelletized and packaged through a twin-screw extruder.
[0038] The preparation method is the same as in Example 1.

Abstract
The invention relates to the field of the modified polystyrene, and provides a high impact-resistance anti-smoldering polystyrene resin composite and a preparation method thereof. The composite comprises the following components: 70 to 85 parts of polystyrene, 8 to 15 parts of fire retardant, 3 to 4.5 parts of auxiliary fire retardant, 0.2 to 1.5 parts of stabilizer, 0.2 to 1.0 part of lubricant,0 to 0.5 part of dispersion oil and 0.2 percent of other assist agents. The high impact-resistance anti-smoldering polystyrene resin composite is prepared by selecting the high impact-resistance polystyrene, fire retardant and other assist agents and by improving the compatibility of the fire retardant and the basal material high impact-resistance polystyrene (HIPS). The composite has high fire retardance, no smoldering and good impact resistance, and is particularly suitable for producing the products requiring high retardance such as electronic elements, parts, shell materials of electronicdevice, and the like.
Description
technical field [0001] The present invention relates to a modified polystyrene composition, furthermore, relates to a high-impact anti-smoldering polystyrene composition and a preparation method thereof. Background technique [0002] High-impact polystyrene has good processability, excellent comprehensive performance and low price. As an important branch of general-purpose plastic polystyrene, high-impact polystyrene is mostly used in the manufacture of electronic components, components, and housings for electronic equipment. In most cases, flame retardant properties are required for these applications, and the general requirement is UL-94-V0 (3.0mm thickness, the same below). When the wall of the part is relatively thin, it is usually required to reach UL-94-V0 V0 (1.5mm thickness). [0003] Due to the nature of high-impact polystyrene, it is a flammable plastic. Usually in order to make it have a certain flame retardant performance, brominated flame retardants are added...
