The invention provides a master batch material, a foaming master batch preparation method and a foaming material preparation method, and belongs to the technical field of high polymer material processing. The master batch material is specifically prepared from, by weight, 30-60 parts of a carrier resin, 30-80 parts of a foaming agent and 0-5 parts of an auxiliary agent, wherein the foaming agent is a medium-high temperature or ultra-high temperature expandable microsphere, the expandable microsphere is characterized in that a volatile expanding agent serving as a core agent is wrapped in a shell formed by a polymer, the shell is formed by polymerizing a monomer mixture of polymerizable monomers, and the polymerizable monomers are at least one of acrylonitrile, acrylate monomers, acrylamide monomers and acrylic acid monomers. According to the treatment scheme, the prepared foaming master batch is uniform in foaming, good in weight reduction effect and wide in application range. 本发明提供了一种母粒材料、发泡母粒制备方法及发泡材料制备方法，属
