This invention discloses a high-temperature resistant and anti-wetting thermal transfer TPU alloy material, its preparation method, and its application in the field of thermal transfer. The high-temperature resistant and anti-wetting thermal transfer TPU alloy material, in terms of mass fractions, comprises the following raw materials: 30-70 parts of TPU, 30-70 parts of PBT, 0.5-5 parts of crosslinking agent, and 2-10 parts of glass fiber. In terms of mass fractions, the raw materials of TPU include: 20-80 parts of polyester diol, 15-35 parts of diisocyanate, 2-15 parts of HQEE, and 2-15 parts of aromatic diamine chain extender. Preparation method: Melt extrude TPU, PBT, glass fiber, and crosslinking agent through a twin-screw extruder to obtain the high-temperature resistant and anti-wetting thermal transfer TPU alloy material; the crosslinking agent is side-fed into the twin-screw extruder in melt form.
