The invention belongs to the technical field of tile surface processing, and more specifically relates to a tile antislipping agent, and a preparation method thereof. The tile antislipping agent is composed of a component A and a component B through combination; the component A comprises, by weight, a corrosion inhibitor, a dispersion stabilizing agent, a humectants, and water; the component B comprises, by weight, a fluorine salt, silicone oil, a surfactant, a dispersion stabilizing agent, a silane coupling agent, multi-thorn nanometer zinc oxide, and water. According to the preparation method, the component A and the component B are mixed at a certain volume ratio to be uniform, and is used for coating of tile surfaces, and tile surfaces are dried. The fluorine salt and the corrosion inhibitor are combined, nanometer structures are formed on tile surfaces, antislipping effect is achieved; the multi-thorn nanometer zinc oxide is capable of increasing the friction force on thorn surfaces, and in using, the corrosion inhibitor and the component B are mixed, so that corrosion inhibitor invalidation can be prevented, and influences on antislipping effect are avoided.
