The invention discloses a preparation method of an anti-radiation basalt fiber material for concrete. The preparation method comprises the following steps: putting chopped basalt fibers into stirring equipment; adding a modifier under a stirring condition, and forming a modified layer on the surface of the short-cut basalt fiber at set modification time and modification temperature; and adding boron carbide, and continuously stirring for a set time at a set temperature, so as to prepare the anti-radiation basalt fiber material for concrete. According to the method, high-speed stirring equipment commonly used in the industry is adopted for conducting dry treatment on the basalt fibers, the surfaces of the basalt fibers are coated with a layer of modifying agent, then boron carbide is added, and therefore the anti-radiation basalt fiber material is prepared, the technological process is simple, feasible, stable, reliable and low in cost, and industrial production is easy to achieve. Production can be carried out under existing production process and equipment conditions, industrial large-scale production can be achieved, and the anti-radiation basalt fiber material can be applied to the field of anti-radiation concrete.
