The invention discloses an ammonium salt organic amine early-strength non-alkaline accelerator which is characterized by consisting of the following raw materials in percentage by mass: 10-25% of hydrofluoric acid, 7-15% of aluminum hydroxide, 0.5-2% of organic amine, 15-40% of aluminum sulfate, 8-20% of sodium sulfate, 3-8% of a sodium hydroxide solution, 1-30% of nitrate amine, 0.2-1% of coppersulfate, 0.1-0.3% of polyacrylamide and the balance of water. The preparation method comprises the following steps: grinding aluminum sulfate and sodium sulfate, and performing screening; and adding the raw materials in sequence to a reactor, controlling the reactant temperature to 50-90 DEG C, after addition, and performing stirring for 30-50 minutes, so as to obtain an organic amine reinforced early-strength non-alkaline accelerator. The ammonium salt organic amine early-strength non-alkaline accelerator prepared by the invention has a standard alkali content, high early-strength, high later-strength and moderate cost, and can be widely used in tunnel engineering and construction.
