The invention discloses a fluoride-free waterproof agent with a stereo silane structure and a preparation method of the fluoride-free waterproof agent. In a formula I of a polymer, R1 refers to a long-chain acrylate structural chain segment, R2 refers to a polyhedral oligomeric silsesquioxane structural chain segment, R3 refers to a functional monomer structural chain segment, X refers to a natural number in a range of 1-150, and Y and Z refer to natural numbers in a range of 1-100. The fluoride-free waterproof agent is aqueous emulsion of the polymer shown as the formula I. By adoption of a polyhedral oligomeric silsesquioxane monomer with a vinyl structure for preparation of the fluoride-free waterproof agent through microemulsion polymerization, introduction of polyhedral oligomeric silsesquioxane with a stereo structure to a lateral group of a polymer long chain is realized, a low-surface-energy siloxane cubic structure can migrate to the fabric fiber surface more effectively in an emulsion film forming spread process to form continuous projections on the fabric fiber surfaces, and consequently waterproof effects are greatly improved. The fluoride-free waterproof agent is an environment-friendly waterproof agent, free of biotoxicity and nondegradability and harmless to organisms and environment.
