Abstract
The invention relates to the field of master batches, and particularly to a preparation method of a dehydrated master batch. The preparation method of the master batch comprises the following steps: (1) uniformly mixing polyethylene, calcium oxide, a dispersant and a stearate according to a proportion to obtain a mixture; (2) putting the mixture into a high-speed mixer, carrying out stirring and carrying out cooling, wherein the stirring time is 30 minutes, the cooling time is 5-10 minutes, and the cooling temperature is 20 DEG C; and (3) pouring the cooled mixture into a twin-screw extruder and carrying out granulation. The master batch prepared by the preparation method can absorb moisture contained in the raw materials, the processing is facilitated, the energy consumption is reduced, and the quality of finished products is improved.
