Problems solved by technology

At present, most of the halogen-free flame retardants used in halogen-free flame-retardant HIPS materials are metal hydrates. The flame-retardant efficiency of this type of halogen-free flame retardants is low, and a large amount of filling is usually required to make HIPS materials have excellent flame-retardant properties. However, such a high filling amount will seriously damage the mechanical strength, formability, and appearance quality of the material, and even make the material lose its use value.

Abstract

The invention provides a halogen-free flame-retardant HIPS composite material. The composite material mainly comprises high-impact polystyrene resin and a composite halogen-free flame retardant according to a ratio by mass percentage being (66%-70%):(30%-34%), the halogen-free flame retardant comprises modified magnesium hydroxide powder, modified aluminum hydroxide powder and red phosphorus microcapsules. The halogen-free flame-retardant HIPS composite material is reasonable in component setting and is prepared by adopting a melt blending method, the preparation is simple to operate and easy to implement, the prepared HIPS composite material is stable in mechanical performance, high in appearance quality, has outstanding and comprehensive flame-retardant performance, and can be widely produced into HIPS sheets in the fields of electronics and office equipment.

Description

technical field [0001] The invention relates to a HIPS material, in particular to a halogen-free flame-retardant HIPS composite material, which 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] Halogen-free flame-retardant tech...
