Coating knowledge: application prospect of nano materials in Marine Coatings

Core tip: nano materials have great application space in the field of naval ship equipment, and ship coating is an important application direction 1、 One of the most important functions of stealth coating is as a part of stealth materials The special effects of nano materials provide a new way and a new absorbing mechanism for stealth materials According to the research, nano multilayer composite films (including multilayer granular films, inorganic / organic multilayer composite films, metal / dielectric multilayer composite films, etc.) are expected to be new materials with high strength and certain frequency bandwidth microwave absorption A company in the United States uses a kind of ultra-fine ceramic ball powder in the protective coating of equipment Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Coating home news: nano materials have a great application space in the field of naval ship equipment, and ship coating is an important application direction 1、 One of the most important functions of stealth coating is as a part of stealth materials The special effects of nano materials provide a new way and a new absorbing mechanism for stealth materials According to the research, nano multilayer composite films (including multilayer granular films, inorganic / organic multilayer composite films, metal / dielectric multilayer composite films, etc.) are expected to be new materials with high strength and certain frequency bandwidth microwave absorption A company in the United States uses a kind of ultra-fine ceramic ball powder in the protective coating of equipment, which can provide the equipment's stealth ability, and can also be coated on electronic equipment to deal with electronic interference The absorption rate of radar wave can reach 99%, while the thickness is only micron The composite powder of nano alumina, iron oxide, silicon oxide and titanium oxide combined with polymer fiber has a strong absorption performance in the mid infrared band, and this composite has a good shielding effect on the infrared detector in this band When this kind of material is added to the coating, it not only has excellent radar wave absorption characteristics, but also has good infrared absorption and dissipation performance, and has obvious stealth function The key technology of submarine camouflage coating is its wet reflectivity and aging resistance The application of nano dark pigments, such as carbon black, iron black and other dark pigments, may be one of the effective ways to reduce the wet reflectance and aging resistance of camouflage coatings 2、 The agglomerates of nano silica in hull paint and antifouling paint are amorphous white powder with three-dimensional network structure It has strong ultraviolet absorption and infrared reflection characteristics, which can improve the anti-aging properties of coatings Nano titanium dioxide also has the effect of absorbing ultraviolet rays, which can improve the aging resistance of the coating Both of them can be used as the main additives in the development of super weather resistant hull paint Ship antifouling coating is one of the materials with the most special performance and the most difficult research technology in ship coatings Due to the increasing attention of the world to the requirements of environmental protection, the time limit for banning the use of organotin antifouling agent in an all-round way has been determined The development of new and efficient antifouling agent has become the focus of ship paint researchers all over the world The use of nano antifouling agents, such as nano cuprous oxide and nano zinc oxide, may be an effective way, or the use of microcapsule technology, the use of a water-soluble resin material to wrap the nano antifouling agent powder into particles, and then prepared in the paint In practical applications, due to the role of seawater, the microcapsules gradually dissolve, slowly and effectively release the antifouling agent to achieve Stable and long-term antifouling function 3、 Nano materials such as nano titanium dioxide and nano zinc oxide can be used as antibacterial agents which are non-toxic to human body, have a wide range of antibacterial activities and have good thermal stability The nonmetallic materials and coatings used in the cabin of ships are easy to grow molds and be polluted because they are often in humid and small space, especially in the subtropical and tropical marine environment It can make use of the antibacterial effect of nano materials to prepare a new type of high-efficiency anti bacteria and anti mildew materials and coatings in the cabin 4、 The fire resistance ability of the ship with fire retardant coating is the key factor to the safety of the ship, especially to the battle and survival of the ship Some nano particles have the function of flame retardant, such as nano zinc oxide can be added to the interior decoration materials of ship cabin as flame retardant or prepared into flame retardant coating, so as to improve the fire resistance of non-metallic decoration materials and flame retardant coating of ship [focus on WeChat official
