The present invention provide it is a kind of it is microwave-assisted prepare the low method for distributing PC/ABS alloy, include the following steps: in parts by weight, to weigh and prepare raw material and be blended, obtain mixture；Preparing raw material includes: 5~95 parts of polycarbonate resin, 5~95 parts of acrylonitrile-butadiene-styrene resin, 0~40 part of filler, 0.2~10 part of auxiliary agent；Mixture feeding is melted into extruder and under microwave heating condition, squeeze out, is granulated, obtains and low distributes PC/ABS alloy.Microwave is introduced into the preparation of PC/ABS alloy by the present invention, heat leak can be ensured to the inside of raw material, hot-spot is avoided to lead to unnecessary overreaction, and then the amount that raw material is decomposed into volatile organic micromolecule compound when producing PC/ABS alloy is effectively reduced, reduce distributing for small organic molecule；It is simple process, environmentally protective, without additionally adding the auxiliary agent for reducing small organic molecule；The performance of PC/ABS alloy will not be impacted. |
