Promotion of Nano-coating materials

Coating materials can be found everywhere in our life, of course, the most common ones are still in our daily life, such as wall paints, wood coatings and so on. But when it comes to nano-coating materials, perhaps you can understand in detail through the following materials.
Necessary Condition:
1) At least one phase has a size of 1~100nm;
2) The performance of the coating is significantly improved or has new functions because of the existence of the nano phase.
Scientifically speaking, nano-coating materials should be called Nano Coating, because the coating itself is a kind of composite material, the reason why called nano-coating materials, just as nano plastics, nano ceramics, etc., is just a customary call, strictly speaking, it should be called nano-composite plastics, nano-composite ceramics. About the definition of nano-coating and called need to further point out that: first of all, not with the nano-materials coating are nano-coating; Secondly, is not a very good performance is nano-coating; Finally, nano-composite coatings are called more scientific, but as a habit, called nano-coating materials are not uncompensated. For example, we usually call acrylic emulsion paint, water-based wood paint, most of the time we introduce them to our customers as environmentally friendly coatings. Therefore, a certain kind of coating does meet the two conditions of nano-coating, we can call it nano-coating.
Composition and System:
According to the composition of nano-coating materials will be divided into three categories: completely for a nano-materials system, two (or more) nano-materials constitute a composite system, called 0-0 composite; add nano-materials composite system, called 0-2 composite.
Traditional coating technology to add nanomaterials, can make the traditional coating of the function of the leap to improve the technology does not need to increase the cost of too much. This nano-added composite system coating will soon be available to the market to show a strong momentum of application.
The use of existing coating technology, for the performance of the coating, the addition of nanomaterials, can be obtained nano-composite system coating. Nanocoatings can be applied to traditional material substrates, powder particles or fibres to modify, coat, modify or add new properties to surfaces.

Functions and their related applications：
1, high hardness and wear resistance: adding nano-phase in high hardness, wear-resistant coatings can further improve the hardness and wear-resistant properties of the coating and maintain high toughness.
2, super lubrication, high temperature resistance, corrosion and oxidation resistance: the addition of nanoparticles to the surface coating can achieve the effect of reducing the coefficient of friction, the formation of self-lubricating materials, and even obtain super lubrication function. The introduction of nanomaterials in the coating can significantly improve the material’s high temperature resistance and oxidation resistance.
3, weather resistance, bactericidal cleaning function: nanomaterials coating can improve the corrosion protection ability of the substrate to achieve the purpose of surface modification and decoration. Adding nanoparticles in paint or coating can further improve its protective ability, which can resist atmospheric and ultraviolet rays, so as to achieve the effect of anti-degradation and anti-discolouration, etc. In addition, it can be used in building materials products, such as sanitary wares, indoor spaces, appliances, etc. Nanomaterials coating can be applied to produce bactericidal and cleaning effects.
4, nano-material coating has a wide range of optical properties: its optical transmission spectrum can be extended from the ultraviolet band to the far-infrared band. Nano-multilayer combination coatings appear to fluoresce in the visible range after treatment, and are used for a variety of optical application needs, such as sensors and other devices. Apply nano-material coating on the surface of various signs to make them light-emitting and reflective; change the composition and characteristics of the nano-coating to get photochromic, thermochromic, electrochromic effects, etc., which can produce special anti-counterfeiting and identification means. In products such as glass and other products coated with nano-materials on the surface coating, can achieve to reduce light transmission and heat transfer effect, produce heat insulation; in the paint to add nano-materials, can play a role in flame retardant, heat insulation, play a role in fire prevention.
5, after nanocomposite coating materials, with excellent electromagnetic properties: the use of nanoparticle coatings formed by the coating has a good wave-absorbing ability, can be used for stealth coating. Nanoparticles of titanium oxide, chromium oxide, iron oxide and zinc oxide with semiconductor properties are added to the resin to form a coating with good electrostatic shielding properties.
