The invention discloses fireproof silica gel soft package and a manufacturing method thereof. The fireproof silica gel soft package comprises a decorative layer, a silica gel foaming layer and a baseplate layer which are sequentially connected from top to bottom, wherein the silica gel foaming layer is prepared from the following components in parts by weight: 75-85 parts of vinyl silicone oil, 35-45 parts of white carbon black, 115-125 parts of hydroxyl silicone oil with viscosity of 1500Mpa.s, 20-30 parts of hydroxyl silicone oil with viscosity of 20-30Mpa.s, 1-2 parts of a platinum catalyst, 3-4 parts of a vinylcyclo retarder, and 70-75 parts of hydrogen-containing silicone oil with hydrogen atom content of 1.6%. The fireproof silica gel soft package is fireproof and waterproof, is simple and easy to process in structure, adopts environment-friendly and pollution-free components, is high in practicability, is easy to clean; and each layer is connected by heating and compounding, sothat connection is tight, coming off is not liable to occur, and the service life is long.
