The present invention discloses a method for preparing a silica sol modified azodicarbonamide foaming agent, and belongs to the field of preparation of foaming agents. According to the method, methyltrimethoxysilane and sodium dodecyl benzene sulfonate are mixed for preparation of a modified silane solution, then ammonia water is dropwise added into the modified silane solution for preparation of silica hydrosol, by mutual dispersion of the silica hydrosol and azodicarbonamide, the azodicarbonamide is fully mixed by silica, and the purposes of not easy agglomeration and moisture absorption of the prepared foaming agent can be achieved. The beneficial effects are that: the preparation method is simple, after the prepared product is mixed with a liquid or a paste-like polymer, the product is not easy to agglomerate; when the foaming agent is used in foaming, particles are dispersed uniformly, the product surface is smooth and free of pocking marks, and the use effect is good.
