| 摘要 |
The additive of the present invention is intended for transferring, to a final coating, biocidal, UV protection, and flame retardant properties and in general the selected properties intrinsic to the metals and compounds of Ag, Au, Cu, Mg, Zn, Bi, Sb, said additive includes the use of solvents, surfactants, dispersants and resins that make it compatible with the final coating. Said coating treated with additive ensures perfect distribution and dispersion of the nanoparticles throughout it, without the need to be subjected to an inorganic substrate. The process for manufacturing the additive starts from existing nanoparticles of the aforementioned metals and compounds, which can be in aqueous organic media or alternatively as dry powders, being submitted to a treatment that allows them to be incorporated in coatings used in a wide variety of environmental conditions. The process can be used for obtaining a variety of functionalized additives. |
