Microwave-assisted method for preparing glass fiber reinforced PC/ABS alloy low in volatility

The invention provides a microwave-assisted method for preparing glass fiber reinforced PC/ABS alloy low in volatility. The method comprises the following steps that raw materials are prepared and include, by weight, 5-90 parts of polycarbonate resin, 5-90 parts of acrylonitrile-butadiene-styrene resin, 1-40 parts of glass fiber, 1-20 parts of compatilizer, 0-20 parts of filler and 0.2-10 parts ofassistant. The polycarbonate resin, the acrylonitrile-butadiene-styrene resin, the glass fiber, the compatilizer, the filler and the assistant are mixed to obtain a mixed material; the mixed materialand glass fiber are fed into an extrusion machine, and fusion, extrusion and granulation are performed under the condition of microwave heating. Microwaves are introduced in PC/ABS alloy preparation,it can be ensured that heat permeates into the preparation raw materials, excessive reaction caused by local overheating is avoided, and volatile small organic molecules are decreased. The microwave-assisted method is simple i
