The invention provides an aliphatic high-efficiency water reducing agent and a preparation method thereof, wherein the aliphatic high-efficiency water reducing agent ensures that concrete has good workability and durability, has small content of sodium sulfate, has small pollution to the environment, and has no crystals in winter. The aliphatic high-efficiency water reducing agent is prepared by the following raw materials in percentage by mass: 10 to 18 percent of 65 to 85 percent anhydrous sodium sulfite, 5 to 10 percent of 96 to 100 percent sodium sulfanilate, 0.5 to 2 percent of 30 to 40 percent sodium hydroxide, 8 to 15 percent of 99 to 100 percent acetone, 15 to 35 percent of 36.5 to 37.5 percent formaldehyde, and the balance being water. The water reducing agent prepared by the method has low requirement on reaction equipment, can save a large amount of investment, and has the advantages of simple and convenient operation, short production period, no waste materials, wide source ...
