Problems solved by technology

However, ABS is easy to burn in the air, and its oxygen index is about 18. It is a flammable material, and it releases black smoke and toxic gases when burned, which is prone to fire safety hazards. Flame retardant modification of ABS, people usually add flame retardant to ABS for flame retardant and smoke suppression treatment
However, the heat resistance of ABS itself is not high, and the heat distortion tempera

Description

technical field [0001] The invention relates to the technical field of ABS preparation, in particular to a flame-retardant and heat-resistant ABS composition and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene resin, referred to as ABS, is a terpolymer composed of acrylonitrile, butadiene and styrene. It is a light yellow or milky white granular non-crystalline resin. Because ABS can show the synergistic performance between the three components, it has excellent properties such as high surface hardness, toughness, good low temperature impact resistance, good creep resistance, good dimensional stability, small molding shrinkage, and excellent processing performance. With comprehensive physical and mechanical properties, it is widely used in household appliances, office supplies, electronic devices, automobile industry and other fields. However, ABS is easy to burn in the air, and its oxygen index is about 18. It is a flammable mate...
