The invention provides a composite foaming functional master batch as well as a preparation method and application thereof, and belongs to the technical field of composite functional master batch granulation. The composite foaming functional master batch is prepared from the following raw materials in parts by weight: 20-50 parts of carrier resin, 50-80 parts of a foaming agent and 0.1-5 part of a nucleating agent, wherein the foaming agent is composed of expandable microspheres and a modified chemical foaming agent, the modified chemical foaming agent is composed of one or two of modified baking soda and modified AC, the mass ratio of baking soda to a modifier in the modified baking soda is 10:(3-10), and the mass ratio of AC to a modifier in the modified AC is 10:(3-10). Compared with an existing foaming agent, the composite foaming functional master batch has the characteristics of high foaming ratio, uniform foaming, good resilience and convenience in operation and processing. 本发明提出了一种复合发泡功能母粒及其制备方法和应用，属于
