摘要:
A method for dispersing a filler having high agglomerating properties in a resin and a micro-dispersing mixer used in the method are provided. Further, a method for producing a sealing material that can avoid a defect caused by agglomerates of a filler (for example, carbon black) in an electronic material such as a semiconductor package, a masterbatch resin produced by the method, and a micro-dispersing mixer used in the method are provided. When a filler is dispersed in a molten resin composition to produce a filler-dispersed molten resin composition, a resin composition containing filler aggregates and a molten resin composition is preliminarily mixed by a mixing means, and, thereafter, the preliminarily mixed mixture is allowed to pass through the micro-dispersing mixer with a fine flow path to disperse the filler in a filler resin composition.
