The air-entraining agent is characterized in that it contains Camellia oleifera saponin; the preparation method is characterized in that: taking Camellia oleifera as a raw material, adopting a hydrophilic solvent aqueous solution, extracting and filtering under conditions above normal temperature; after the filtrate is separated by membrane under pressure to remove macromolecular impurities, Remembrane separation to remove small molecular impurities, and concentrated into a concentrated solution with a Baumé degree of not less than 10 Be (60 ° C), spray-dried into a solid dosage form; or by adding modifiers to make an air-entraining agent for liquid dosage forms. The invention has novel concept, abundant raw materials, high production efficiency, low production energy consumption, low production cost, simple preparation method, green environmental protection, convenient implementation, small amount of air-entraining agent, large gas production, and introduced bubble pore size during concrete engineering application. Small, small spacing, concrete pores are more uniform, dense, non-connected, and have greater promotion.
