The present invention relates to a kind of preparation methods of Fanglun slurry cake composite master batch.The inorganic filler generated by in-situ polymerization is adequately isolated Fanglun slurry cake, and coupling agent is recycled further to modify the pulp after isolation, with thermoplastic particles or powder extruding pelletization after dry and high speed fluffy, prepares corresponding Fanglun slurry cake composite master batch.This method can be such that the microfibril of Fanglun slurry cake is fully extended out, and generated in-situ particle plays better buffer action to fento, and the combination of pulp and matrix can be further increased after coupling agent modified.Compared with directly Fanglun slurry cake is isolated with inorganic particle, the isolation effect of this method becomes apparent from, and the properties of basis material also obtain raising. |
