Abstract

The invention relates to a glass fiber-reinforced flame-retardant polystyrene resin composition, which comprises the following components in weight part: 50-70 parts of polystyrene resin, 11-13 parts of halogenated flame retardant, 3-4 parts of antimonic flame retardant, 6-20 parts of glass fibers, 3-7 parts of flexibilizer, 3-5 parts of compatilizer, 0.2-0.4 part of anti-oxidant, 0.5-1.5 parts of lubricant, and 0.1-0.2 part of anti-dripping agent. According to the technical scheme of the invention, the impact strength of the resin composition is greatly improved. Meanwhile, the defect that the existing glass fiber-reinforced flame-retardant polystyrene resin is poor in impact strength can be overcome. The application range of glass fiber reinforced flame-retardant polystyrene is expanded. The glass fiber-reinforced flame-retardant polystyrene resin provided by the invention is high in impact strength, high in rigidity, high in flame-retardant efficiency, good in flowability, and the like. Meanwhile, the glass fiber-reinforced flame-retardant polystyrene resin has a wide application prospect to meet the market requirements of light weight and thin wall upside to the current trend.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a glass fiber reinforced flame-retardant polystyrene resin composition and a preparation method thereof. Background technique [0002] Polystyrene is a flammable polymer material. It is widely used in electronic appliances, office equipment, communication equipment, household appliances and other fields. When it is used in products with flame retardant requirements such as electronic appliances, it needs to be flame retardant modified. to meet its safety and fire protection requirements; at the same time, under the market trend of constant pursuit of lightweight and thin walls, the rigidity of polystyrene has been difficult to meet the performance requirements of parts, and the dimensional stability is poor, so it is necessary to To modify polystyrene to improve its rigidity and dimensional stability, the most effective and low-cost method is glass fiber reinforced mo...
