Problems solved by technology

[0002] At present, the materials used for ship propellers are mainly made of stainless steel. During the operation of the ship, under the action of high-speed water erosion and centrifugal force, the surface of the propeller will not produce marine biofouling; when it is moored, the propeller is prone to marine biofouling
The marine biofouling of the propeller, especially the marine biofouling of hard shells, will increase the navigation resistance and fuel consumption of the ship, reduce the speed of the ship, and at the same time incre

Abstract

The invention discloses an antifouling paint for marine propellers. The antifouling paint is prepared from a material a and a material b, wherein a weight ratio of the material a to the material b is1 to (0.2 to 0.5); the material a is prepared from the ingredients in parts by weight: 100 to 140 parts of bisphenol F type liquid resin, 10 to 20 parts of composite flexibilizer, 8 to 14 parts of kieselguhr, 4 to 8 parts of tourmaline powder, 4 to 6 parts of germanite, 15 to 25 parts of filler, 2 to 4 parts of dispersant, 2 to 4 parts of defoamer and 2 to 4 parts of wetting agent; the material bis prepared from the ingredients in parts by weight: 6 to 12 parts of diethylaminopropylamine and 40 to 60 parts of water. The antifouling paint disclosed by the invention is suitable for varieties ofenvironments and temperatures, can avoid defects of surface upwarping, falling and the like caused by poor adhesive force, has high adhesion strength with the surfaces of the propellers and has excellent waterproof performance and long service life.
