This invention discloses a reinforced halogen-free flame-retardant battery casing material and its preparation method, belonging to the technical field of battery casing materials. It comprises the following raw materials in parts by weight: 78-84 parts of ABS matrix resin, 14-16 parts of flame retardant, 0.2-0.3 parts of antioxidant, 0.8-0.9 parts of light stabilizer, and 0.8-0.9 parts of processing aid; the flame retardant is hyperbranched flame-retardant graft-modified zirconium phosphate. According to the formula, the antioxidant and light stabilizer are weighed and mixed evenly, then the flame retardant, processing aid, and ABS matrix resin are added and pre-mixed in a mixer. The pre-mixture is then fed into a twin-screw extruder for extrusion and granulation. The prepared flame-retardant plastic particles are dried and then injection molded. This invention achieves a V-0 flame retardant rating by adding the halogen-free flame retardant hyperbranched flame-retardant graft-modified zirconium phosphate. Furthermore, the addition of the flame retardant not only does not reduce the mechanical properties of the material but actually improves them.
