Problems solved by technology

Although some manufacturers switch to magnesium hydroxide whiskers with higher modulus and strength as a flame retardant, which can simultaneously play a role in flame retardancy and reinforcement for HIPS materials, but due to the high surface energy of magnesium hydroxide whiskers , lack of affinity with HIPS, when the amount of magnesium hydroxide whiskers is large, its superiority cannot be fully reflected in HIPS materials

The invention discloses the high-performance flame retardant HIPS composite material. The HIPS composite material has reasonable preparation, the preparation process is simple and convenient and the HIPS composite material is toxin-free and cheap so that the HIPS composite material is convenient for industrial production; and the HIPS composite material has good flame retardant performance, has high tensile strength and impact toughness and has a wide application field.

Description

technical field [0001] The invention relates to a HIPS material, in particular to a HIPS composite material with flame-retardant effect, and belongs to the technical field of plastic materials. Background technique [0002] High-impact polystyrene HIPS is a commonly used plastic with high mechanical properties. The HIPS sheet produced by it is widely used in various industries such as electronic appliances, food, medicine, office supplies, toys, etc. Due to the influence of HIPS molecular structure and components, HIPS is flammable, which requires flame retardant modification of HIPS to obtain HIPS materials that meet the requirements of flame retardant use. Usually, the flame retardancy of HIPS materials is achieved by adding an appropriate type and amount of flame retardants to the HIPS matrix resin, and utilizing the gas phase and condensed phase flame retardancy of the flame retardant / HIPS composite system during combustion. [0003] As an environment-friendly flame ret...
