After nano-silver and other nano-products have high-tech meanings, they must be matched with the corresponding nanotechnology. After the nano-scale materials are simply added, the products with no significant improvement in performance are not nano-products. Some people say that Nano-coatings are more suitable as nano-composite coatings. Coatings themselves are a kind of composite materials. Therefore, coatings with nano-materials can be called nano-coatings. In foreign countries, many coating products use nanotechnology, but because of technical confidentiality, it is not directly called.
The Green Show will not only showcase “unflavored” paints, but also showcase advanced technologies for non-toxic coatings, as well as exhibiting high-tech nano-coatings. This high-tech nano-coating is not only non-toxic and harmless, but also slowly releases a substance that degrades indoor formaldehyde, xylene and other harmful substances.
2 coating properties
For example, when the particle size enters the nanometer scale, the increase of the surface active center of the material can improve its chemical catalysis and photocatalytic reaction ability, and the coating can be self-cleaning under the action of ultraviolet light and oxygen; the surface active center and the functional group of the film-forming substance can occur. The combination of chemical bonds greatly increases the rigidity and strength of the coating, thereby improving the scratch resistance of the coating; the surface of the nano-material with high surface energy can be modified to obtain the characteristics of both hydrophobic and eucalyptus oil, which can be used for interior and exterior wall coatings. Improve the anti-staining property of the coating and improve the weather resistance; some nano-materials with a particle size of less than 10 nm have absorption and scattering effects on the Y-ray, which can improve the radiation-proof ability of the coating, and can be used in interior and exterior wall coatings. Anti-helium effect; the use of nano-materials in the primer can increase the adhesion of the primer to the substrate, improve the mechanical strength, and the strong force and filling effect of the nano-scale pigment and primer can help improve The interface of the primer-coating layer; the nano-material can play the surface filling and smoothing effect in the topcoat, improve the gloss of the topcoat and reduce the resistance; The addition of silica to the exterior wall coating can improve the scrub resistance of the coating; the addition of nano-titanium dioxide to the exterior coating of the building can increase the weatherability of the latex paint to a new level, while also providing the aging resistance of the latex paint. Great improvement; nano-zinc oxide added to the exterior wall coating can make the coating have ultraviolet shielding, infrared absorption and sterilization and anti-virus effects.
