The present invention discloses a method for preparing spray-free PC/ABS material by a paraffin method and a twin-screw extruder thereof, relating to the field of PC/ABS material preparation, comprising an extruder main body, the top of the extruder main body is fixedly communicated with a recovery device, one end of the recovery device is fixedly communicated with a conveying device, the other end of the conveying device is fixedly communicated with a supplement device, and a heating plate is movably mounted on the outer wall of the extruder main body. In the present invention, the driving and volatilization of paraffin fluid make the mixing of aluminum powder and ABS material more uniform. At the same time, a volatile paraffin condensation and recovery system is designed, and the recovered paraffin can be recycled to achieve the purpose of environmental protection. The spray-free PC/ABS material prepared by this method has improved fluidity and uniformity of the contained aluminum powder, and can reduce the problems of flow marks and weld lines.
