To improve the sand and gravel erosion resistance of the helicopter rotor leading edge，elastic resin was used as the base resin，silicon carbide and polytetrafluoroethylenepowder were used as wear-resistant fillers to prepare component A of the elastic sand corrosionresistant coatings，and elastic curing agent was used as component B of sand corrosion resistantcoatings. The focus was on discussing the effects of different base resins，different curing agents，different ratios of n（— NCO）to n（— OH）， different wear-resistant fillers，and the amount of wear-resistant fillers on the performance of elastic sand corrosion resistant coatings.The results showed that the prepared elastic sand corrosion resistant coatings had a wear lossof 10mg，a tensile strength of 26. 3 MPa，a fracture elongation of 278%，and excellent sand and dust resistance，which could meet the requirements for protecting the stainless steel partsof the helicopter rotor leading edge.
