Description

technical field [0001] The invention relates to the technical field of PC / ABS alloy materials for automobiles, in particular to a flame-retardant electroplated PC / ABS alloy material for automobiles and a preparation method thereof. Background technique [0002] ABS resin is a fine polymer material with high strength, good toughness, easy processing and high cost performance. It is suitable for making general mechanical parts, wear-reducing and wear-resistant parts, transmission parts and electrical parts. Poor weather resistance, poor mechanical properties and flammability limit its application. PC is a high-toughness thermoplastic resin with excellent properties such as transparency, heat resistance, corrosion resistance, and high impact strength. The ABS / PC blend obtained by melt blending ABS and PC has easy processing, good low temperature toughness, excellent impact resistance and good heat resistance, so it is used as an important commercial material in many processing...
