Polycarbonate resin / styryl resin non-halogen flame-retardant composite material

Abstract

The invention relates to the technical field of the high polymer materials, in particular to a halogen-free flame-retardant compound material consisting of polycarbonate resin and acrylonitrile-styrene-acrylate. The halogen-free flame-resistant compound materials comprise polycarbonates (PC), acrylonitrile-styrene-acrylates, anti-flamming agents, and antioxidant additives. The invention is characterized in that the compound materials also comprise nanometer kaolin accounting for 3 per cent to 20 per cent of the total weight. The invention enhances the rigidity of the material, greatly improves the size stability of the material and maintains the impact ductility of the material simultaneously.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant composite material of polycarbonate resin and styrene-based resin. Background technique [0002] Compositions of polycarbonate resins and styrene-based resins, especially ABS, have high impact resistance, good heat resistance and excellent processability. The composition is widely used in auto parts, home appliances and electrical and electronic components, etc., and there is a requirement for heat-resistant and flame-retardant materials, and halogen compounds are usually added to provide flame retardancy. However, halogenated flame retardants have become pollutants diffused everywhere in the daily environment, and the threats to the environment and human beings are increasing. The act of manufacturing, recycling, or discarding home appliances and other consumer products is the main way these pollutants are released into the environment. ...

Problems solved by technology

However, the flame-retardant PC / ABS alloy added with such flame retardants still has some shortcomings in performance, such as poor dimensional stability of the material, especially poor rigidity. Therefore, it is necessary to add some reinforcing materials to make up for these shortcomings, but ordinary Although the reinforced material (such as ordinary filler) can increase rigidity and improve dimensional stability, the toughness of the material will decrease significantly, and the surface gloss will become very dull
