The invention relates to powder material for boiler tube high temperature resistance and wear resistance protecting and a preparation method thereof, and belongs to the technical field of surface engineering. The power material comprises the following components, by weight percentage, 10-20% of titanium-nickel alloy powder, 1.5-3.5% of graphite powder, 0.5-1% of silica powder, 8-25% of nickel-chromium alloy powder Ni80Cr20, 5-10% of iron boride powder and the balance of tri-chromium dicarbide powder. The preparation method comprises the following steps that power material is prepared, mix powder is formed, liquid-containing binders are prepared, sizing agents are prepared from the mix powder, prilling is completed through spray drying, and finished product powder is prepared from screening the prilling powder and is used for preparing a cladding layer. The metal cladding layer with high wear resistant duplex ceramic is formed through laser cladding, and the hardness ranges from 1100 HV to 1600 HV, so that the powder material for boiler tube high temperature resistance and wear resistance protecting and the preparation method thereof has the advantages that efficiency of the laser cladding is higher, loss of powder spattering is low, grain of the cladding layer is tiny, wear resistance of the cladding layer is high and the like.
