Molecular material.PC and its solvent butyl oxide link used in the present invention, the optional water of flocculation solvent, methanol, ethyl alcohol, acetone, second two
Alcohol etc., preferably water, ethylene glycol.
Water,, will not when being directly added into polymer composite mixed liquor since its surface tension is very big as flocculation solvent
Spheric granules is formed, and film is formed on the surface of water, therefore, it is necessary to add in surfactant in water to reduce its surface
Power.As surfactant, (including higher fatty acid salt, aliphatic hydrocarbon is generally 11-17 carbon to optional anion surfactant
Long-chain；Hydrosulphate, fat hydrocarbon chain is between 12-18 carbon；Azochlorosulfonate acid compound, fat hydrocarbon chain is between 8-18 carbon), sun from

Obtained polymer composite mixed liquor can directly obtain polymer composite master batch by way of stirring or flowing,
So as to eliminate traditional extruding pelletization process.Prilling process proposed by the present invention greatly reduces thermal energy in conventional method
Loss, and by that recycling design can be reused to greatest extent for the selection for the solvent that flocculates, this can be also reduced due to molten
Cost caused by the use of agent.
As the process by stirring-granulating, as shown in Figure 1.Obtained polymer composite mixed liquor is added drop-wise to wadding
In solidifying solvent, by stir flocculation solvent can the particle of polymer composite mixed liquor do not flock together and formed
Polymer composite master batch.Used agitating mode can be mechanical agitation or magnetic agitation.In addition, it is flocculated by heating
Solvent can cause master batch more quickly to solidify.It again can be by polymer composite master batch and mixed solvent point by filtering
From.
As the process by fluidized granulation, as shown in Figure 2.Polymer composite mixed liquor is added drop-wise in flowing
It flocculates in solvent, the flocculation solvent of flowing can prevent adjacent polymer composite master batch adhesion from luming, molten with flocculating
Agent flow on filter screen to collect composite masterbatch, and mixed solvent can be collected in container.
Most polymer composite master batch obtains the master batch that can be molded by drying at last.
