The present invention discloses a glass fiber reinforced halogen-free flame retardant polyester alloy material and a preparation method thereof, relating to the technical field of flame retardant material preparation. The preparation process of the glass fiber reinforced halogen-free flame retardant polyester alloy material comprises: firstly, adding 40% polyethylene terephthalate (PET), 35% polybutylene terephthalate (PBT), 10% ammonium polyphosphate, 5% glass fiber, 5% tribasic lead sulfate and 5% copolyester PET into a medium-speed mixer; adjusting the medium-speed mixer to a speed of 200 r/min for a mixing time of 5 minutes; standing after mixing, and then feeding the mixed raw materials into a twin-screw extruder; finally obtaining the flame retardant material through melting, extrusion and pelletization. Through the design of the glass fiber reinforced halogen-free flame retardant polyester alloy material, the present invention improves the mechanical properties, creep resistance, fatigue resistance, abrasion resistance, electrical insulation properties and chemical resistance of the flame retardant material, and solves the problems of poor thermal stability and weather resistance of traditional flame retardant materials.
