Abstract
The invention relates to an UV nano metallic coating material. The UV nano metallic coating material is prepared from composite modified polyurethane acrylate, modified epoxy acrylic resin, modified pure acrylic oligomer, 1,6-hexanediol diacrylate, monomer tripropylene glycol diacrylate, monomer tetramethyl propylene diamine and a complex type photoinitiator. The UV nano metallic coating materialprovided by the invention is excellent and balanced in various properties, all ingredients of the formula are matched with one another, and properties such as the metal surface adhesion power of the coating material, the impact resistance, the elasticity of a cured film, the hardness and flexibility of the cured film, the bonding strength and durability of the coating material and the yellowing resistance and transparency of the coating material are balanced, so that the coating material has the above-mentioned characteristics, particularly excellent adhesive power, flexibility and impact resistance. Meanwhile, the coating material provided by the invention is a nano coating material and is fine in particle, so that metal surfaces can be uniformly coated with the coating material; and thesurface of a coating film is very flat and does not occur defects such as trickling or vortex eyes, so that the coating film is attractive and can protect the surface of a metallic substrate, and thecoating material has a broad application prospect.
Description
technical field [0001] The invention relates to the technical field of coatings, in particular to a UV nano metal coating with excellent adhesion, flexibility and impact resistance. Background technique [0002] UV nano-metal coatings are used for rust prevention of steel, color-coated steel plates, aluminum alloy door and window protection, and metal decorative panel manufacturing. After the metal surface is coated with UV coatings, it is both beautiful and can protect the surface of the metal substrate. In most cases, metals are exposed to complex external environments, which can easily cause various damages such as wear and scratches on the surface of the metal coating. This is all due to the poor adhesion of the coating to the metal material. Due to the smooth surface of the metal substrate and the presence of an oxide film, these factors will affect the adhesion between the coating film and the metal, which will also affect the coating film. flexibility and impact resi...
