Three applications of titanium nanomaterials in ship coatings

1. Ship hull paint and ship bottom anti-fouling paint
The nano-silica aggregate is an amorphous white powder, the surface state is a three-dimensional network structure. It has strong ultraviolet absorption and infrared light reflection characteristics, which can improve the anti-aging performance of the coating. Nano titanium dioxide also has the effect of absorbing ultraviolet light, which can improve the aging resistance of coatings. They can both be used as major additives in the development of ultra-weather-resistant ship hull paints.
Marine antifouling coatings have always been one of the most special properties of Marine coatings, research technology is one of the most difficult materials, due to the increasing attention to the requirements of environmental protection in the world, in the total ban on the use of organic tin antifouling agents has been determined the time period, the development of new and efficient antifouling agents has become the focus of Marine paint researchers in various countries. The use of nano-level antifouling agents, such as nano cuprous oxide, nano zinc oxide, etc., may be an effective way, or the use of microencapsulation technology, with a water-soluble resin material to coat the nano antifouling agent fine powder to form particles, and then prepare in the paint, in practical applications, due to the role of seawater to dissolve the microcapsules gradually. The antifouling agent is released slowly and effectively to achieve a stable and long-lasting antifouling function.

2. Antibacterial paint
Nano titanium dioxide, nano zinc oxide and other nanomaterials can be used as non-toxic to human body, a wide range of antibacterial, excellent thermal stability of antibacterial agents. The non-metallic materials and coatings used in the cabin of the ship are very easy to grow mold and be polluted because they are often in the environment of humidity and small space, especially in the subtropical and tropical Marine environment. The antibacterial effect of nanomaterials can be used to prepare new high-efficiency anti-bacterial and anti-mold materials and coatings in the cabin.

3. Ship flame retardant paint
The fire prevention capability of ship is a key factor related to the safety of ship, especially the combat effectiveness and survivability of ship directly. Some nanoparticles have flame retardant functions, such as nano-zinc oxide can be added as a flame retardant to the decorative materials in the ship cabin or formulated into flame retardant coatings to improve the fire resistance of non-metallic decorative materials and flame retardant coatings on ships.
