The application discloses a low interfacial tension surfactant and a preparation method and application thereof in anti-freezing glass water, and relates to the technical field of surfactants. The low interfacial tension surfactant is prepared by the following steps: 2,4,6-trivinyl-2,4,6-trimethylcyclotrisiloxane is reacted with 5-amino-1-mercaptopentane under the action of a photoinitiator to generate an intermediate 1,3,6,9,12,15,18-hexaoxanonadecane-1-amine, the intermediate 1 is reacted with 1H,1H-perfluorooctyl acrylate to generate an intermediate 2, the intermediate 2 is reacted with epichlorohydrin to generate an intermediate 3, and the intermediate 1 is reacted with the intermediate 3. The prepared surfactant has low surface tension and contact angle, and exhibits excellent wetting performance and low-temperature stability.
