The invention discloses sulphate aluminium cement and a preparation method thereof, and relates to the field of building materials. The sulphate aluminium cement comprises the following components in percentage by mass: (1) 50.0%-70.0% of sulphate aluminium cement clinker, (2) 3.0%-8.0% of alginate fiber, (3) 10.0%-25.0% of ferro-alloy slag, (4) 5.0%-15.0% of boron slag, (5) 5.0%-10.0% of pulverized fuel ash, and (6) 2.5%-5.0% of gypsum. The preparation method of the sulphate aluminium cement comprises the following steps: (1) preparing materials, (2) grinding, and (3) pulverizing. The sulphate aluminium cement has the characteristics of being high in hardening rate and high in early strength, and besides, the condition that the long-term strength of the sulphate aluminium cement is reduced greatly is avoided, and the service life of the sulphate aluminium cement is prolonged. Besides, the preparation method for the sulphate aluminium cement, provided by the invention, adopts primary grinding and mixed pulverizing processes, the granularity of the prepared sulphate aluminium cement is relatively small, the specific surface area is relatively large, and the performance is stable.
