I. Hull paint and bottom antifouling paint
The aggregation of nanometer silica is a kind of amorphous white powder, and the surface state is a three-dimensional net structure. It has very strong ultraviolet absorption and infrared reflectance, which can improve the anti-aging performance of coatings. Nano-titanium dioxide also has the effect of absorbing ultraviolet rays, can improve the aging resistance of coatings. They can be used as the main additive for the development of super weathering Hull paints.
Marine antifouling paint has been the most special performance in marine coatings, one of the most difficult materials to study technology, because of the increasing attention to environmental protection in the world, the time limit for the use of Organotin antifouling agent has been established, and the development of new and efficient antifouling agent has become the attention goal of the ship paint researchers. The use of nano-scale anti-fouling agents, such as nano-cuprous oxide, nano-ZnO may be an effective way, or the use of Microcapsule technology, a water-soluble resin material is used to form particles of nanometer antifouling agent, then prepared in the coating, in practical application, because of the effect of seawater, the microcapsules gradually dissolve, and the antifouling agent is released slowly and effectively to achieve a stable and long-lasting anti-fouling function.
II. ANTIBACTERIAL COATINGS
Nano-titanium dioxide, nano-zinc oxide and other nano-materials can be non-toxic to the human body, wide range of antibacterial, good thermal stability of antibacterial agents. Non-metallic materials and coatings for the interior of Ships cabin because of the often humid and small space pollution environment, especially in the subtropical and tropical marine environment, very easy to grow mold and contaminated. The antibacterial action of nanometer materials can be used to prepare new type of high efficient anti bacteria and mildew resistant materials and coatings in cabin.
III. Fire retardant coatings for ships
The fire-fighting ability of ships is the key factor that affects the ship's safety, especially the warship's combat effectiveness and survivability. Some nanoparticles have the function of flame-retardant, such as nano-zinc oxide can be added to the ship cabin interior decoration materials or with flame retardant paint, improve the ship's non-metallic decorative materials and fire-retardant paint.
