The invention discloses a coating material for a voyage screw propeller paddle. The coating material is prepared from the following raw materials in parts by weight: 50 to 60 parts of vinyl resin, 60 to 70 parts of styrene, 5 to 10 parts of polybutylene terephthalate, 15 to 20 parts of polyvinylidene fluoride, 15 to 20 parts of a modifier, 5 to 10 parts of a cross-linking agent and 5 to 10 parts of a stabilizer. The coating material for the voyage screw propeller paddle, disclosed by the invention, is densely applied on the surface of the paddle and a formed protection coating has relatively high hardness and adhesive force, high impact-resisting strength and extremely strong wearing resistance; the protection coating is not broken and does not fall off under high-strength seawater abrasion. The coating material disclosed by the invention has extremely corrosion resistance; even if the coating material is immersed in high-concentration seawater for long time, the coating material is not corroded by the seawat
