Abstract

The invention discloses a high content inorganic powder modified filler masterbatch. The high content inorganic powder modified filler masterbatch is prepared form the following raw materials: inorganic powder, elastomer materials, a graft compatibilizer, a dispersing agent, siloxan and trifluorobromopropene monomer. The filler masterbatch can significantly improve the tensile strength and elongation at break of plastics, the preparation cost is low, and the filler masterbatch can be used for plastic filling granulation, filling injection molding, film blowing filling, wire drawing filling andthe like.

Description

technical field [0001] The invention belongs to the technical field of filler masterbatch preparation, and in particular relates to a high-content inorganic powder modified filler masterbatch. Background technique [0002] The scientific and appropriate use of various fillers in plastic processing can not only save precious synthetic resins made from petroleum, but also improve the performance of some aspects of plastic materials while reducing the cost of raw materials for plastic products. [0003] Whether inorganic powder can be used as plastic filler needs to meet at least two conditions: first, inorganic powder is inorganic, plastic is organic, the compatibility between the two is very poor, and the mechanical properties of plastic are greatly reduced. Therefore, it is necessary to Inorganic powders are organically modified; second, inorganic powders must have relatively stable chemical properties, and there will be no melting, decomposition, etc. during the processing ...
