Problems solved by technology

However, the higher filling ratio of inorganic fillers and smaller particle size characteristics make it difficult to disperse into a uniform system in the resin carrier
The traditional coupling modification treatment technology can only partially reduce the surface energy of the filler particles, and cannot realize the uniform blending of the inorganic filler and the organic carrier resin, which in turn makes it easy to cause scars caused by uneven dispersion and production during the stone paper processing process. However, under the traditional stone paper masterbatch processing system, in order to solve the above problems, it is necessary to increase the amount of coupling agent or dispersant, which pushes up the production cost and seriously limits the stone paper.

Description

technical field [0001] The invention belongs to the technical field of stone papermaking, and in particular relates to a multilayer coated core-shell structure stone paper functional masterbatch and a preparation method thereof. Background technique [0002] Stone paper is made of inorganic powder as the main raw material, mixed with resin carrier, melted, extruded and thinned. The material has the dual characteristics of ordinary fiber paper and plastic products, and has great application value in the fields of packaging, printing, electronics and biopharmaceuticals. However, the higher filling ratio of inorganic fillers and smaller particle size characteristics make it difficult to disperse into a uniform system in the resin carrier. The traditional coupling modification treatment technology can only partially reduce the surface energy of the filler particles, and cannot realize the uniform blending of the inorganic filler and the organic carrier resin, which in turn make...
