The leading cause of death in fires is not death by burning, but by choking with smoke. The PC/ABS alloy material is like most other plastics, belongs to a combustible material, and emits a large amount of smoke during combustion. Because of the great use of the PC/ABS alloy material in the fields of electronic appliances, automobile industry and the like, the reduction of the smoke density of the PC/ABS alloy material has important significance from the viewpoint of protecting the life safety of people.
The smoke density refers to the light flux loss caused by the reflection of light by solid dust in smoke generated by a material under specified experimental conditions, and is an important index for evaluating the flame retardance of plastics. The PC/ABS material with low smoke density reported at present is mainly subjected to smoke suppression treatment by adding molybdenum compounds, but the molybdenum compounds are expensive, and some metal ion compounds can cause polycarbonate degradation and influence product performance. Chinese patent CN102604315A discloses a low-smoke-density PC/ABS alloy for automobile interior parts and a preparation method thereof, wherein four flame-retardant smoke inhibitors such as zinc borate, molybdenum trioxide, ammonium octamolybdate, zinc molybdate and the like are compounded in the low-smoke-density PC/ABS alloy, so that the flame-retardant effect is effectively improved in the PC/ABS alloy, the smoke density can be effectively reduced, and the smoke is efficiently inhibited. However, molybdenum compounds such as molybdenum trioxide, ammonium octamolybdate and zinc molybdate have also been used in this patent.

Further, in some embodiments of the present invention, the flame retardant is preferably bisphenol a-bis (diphenyl phosphate) (BDP for short). BDP is a flame retardant for industrial production, has low price and excellent flame retardant effect, and is suitable for large-scale industrial production and application.
Further, in some embodiments of the present invention, the antioxidant is preferably one or both of antioxidant 1010 and antioxidant 168.

(1) weighing the raw materials, and respectively drying;
(2) and (2) mixing the dried raw materials in the step (1), and then carrying out melt extrusion on the mixed raw materials through a double-screw extruder to obtain the low-smoke-density flame-retardant PC/ABS alloy.
Further, the drying treatment in the step (1) is drying for 7-9 hours at a temperature of 85-110 ℃.
