The application relates to the technical field of C09D5 / 03, in particular to a high-transmittance acrylic powder resin and a preparation method thereof, raw materials for preparing the acrylic powder resin by weight percentage at least include: 80-100 parts of soft monomers, 400-600 parts of hard monomers, 0-10 parts of carboxyl functional monomers, 200-400 parts of ester functional monomers, 20-100 parts of hydroxyl functional monomers, 10-30 parts of initiators, 5-20 parts of chain transfer agents, 800-1200 parts of solvents and 1-10 parts of nano additives; the nano additives are added, and the synthesis process of the acrylic resin is optimized, so that the prepared acrylic powder resin has high transmittance and good weather resistance, and can meet the actual use requirements in the fields of automobile hubs and photovoltaics.

The present invention discloses a method for preventing the inner wall of a ship's seawater pipe from being corroded and fouled, and relates to the field of ship protection technology. The present invention is applied to a composite material anti-corrosion coating and anti-fouling technology for the inner wall of a ship's seawater pipe. The coating has excellent anti-corrosion and anti-fouling capabilities, excellent mechanical impact resistance, and good adhesion between the coating and the pipe wall substrate, which perfectly demonstrates the dual protection technology of the coating's anti-corrosion and anti-fouling. The coating prepared by the present invention is composed of polyurea modified resin, inorganic antibacterial powder and other additives and solvents. Compared with traditional polyethylene anti-corrosion coatings, it has better corrosion resistance and mechanical impact resistance, and stronger adhesion to the substrate. It will not fall off or even block the pipeline, affect the normal operation of the pipeline system, or even constitute a safety hazard that poses a normal and safe navigation of the ship, which may occur when polyethylene materials are used as anti-corrosion coatings.
